English Abstract


Expert system and method for computing an application procedure for
painting vinyl panels a target color at a paint application site while
preventing vinyl warping. A target reflectivity indicator is computed for
the vinyl panels once painted. When the target color and target
reflectivity indicator are met by application of the multiple paint layers,
the application procedure computed identifies a pigmentable waterborne
paint composition , one or more proportioned paint pigments to achieve
the target color at a predictable transmissivity and a preparatory
waterborne paint composition considering a corresponding predictable
reflectivity. Applying the pigmentable waterborne paint composition,
once pigmented with the one or more proportioned paint pigments, over
the preparatory waterborne paint composition meets the target
reflectivity indicator for the vinyl panels at the target color. Instructions
are then sent to a remote device comprising the application procedure
for painting the vinyl panels at the target color while preventing vinyl
warping.

SYSTEM AND METHOD FOR SELECTING PAINT COMPOSITIONS
PER LAYER BASED ON SUBSTRATE CONDITIONS
Technical field
100021 The present invention relates to a paint compositions and, more
particularly, to
different exterior paint compositions.
Background
[0003] Different materials are used to cover exterior of houses. Vinyl is
a very popular
material for covering houses. Typically, long and narrow panels made of
colored unplasticized
polyvinyl chloride (uPVC or simply PVC or vinyl) are intertwined over exterior
walls. It has
been noticed that vinyl panels, after being painted, sometimes have a greater
tendency to warp
than unpainted vinyl panels.
[0004] The present invention addresses this problem.
Summary
100051 This summary is provided to introduce a selection of concepts in a
simplified form
that are further described below in the Detailed Description. This Summary is
not intended to
identify key features or essential features of the claimed subject matter, nor
is it intended to be
used as an aid in determining the scope of the claimed subject matter.
[0006] A first aspect of the present invention is directed to an expert
system for computing
an application procedure for painting vinyl panels a target color at a paint
application site while
preventing vinyl warping. The system comprises a non-transitory memory, a
processing module
comprising one or more processors and a network interface module comprising
one or more
physical network interface. A first set of software instructions, stored in
the non-transitory
memory, when executed by the processing module, obtain a thickness indicator
of the vinyl
1
CA 2979100 2017-09-12

panels to be painted at the paint application site considering a request
received, for the
application procedure at the application site, through the network interface
module from a
remote device. A second set of software instructions, stored in the non-
transitory memory, when
executed by the processing module, compute, based on the thickness indicator
and the target
color for the vinyl panels, a target reflectivity indicator for the vinyl
panels once painted for
preventing vinyl warping. A third set of software instructions, stored in the
non-transitory
memory, when executed by the processing module, determine that the target
reflectivity
indicator for the vinyl panels once painted the target color is met by
application of multiple paint
layers of different paint compositions. A fourth set of software instructions,
stored in the non-
transitory memory, when executed by the processing module upon determination
that the target
color is met by application of the multiple paint layers compute the
application procedure. The
computed application procedure that identifies a pigmentable waterborne paint
composition, one
or more proportioned paint pigments to achieve the target color at a
corresponding predictable
transmissivity and a preparatory waterborne paint composition considering a
corresponding
predictable reflectivity. Applying the pigmentable waterborne paint
composition, once
pigmented with the one or more proportioned paint pigments, over the
preparatory waterborne
paint composition on the vinyl panels meets the target reflectivity indicator
at the target color.
The fourth set of software instructions, stored in the non-transitory memory,
when executed by
the processing module also send instructions, through the network interface
module to the
remote device, comprising the application procedure for painting the vinyl
panels at the target
color while preventing vinyl warping.
100071 The non-transitory memory may comprise one or more preparatory
records each
associated with one of at least one preparatory waterborne paint composition
of predictable
reflectivity, a plurality of pigment records each associated with a paint
pigment having a
pigmentation identifier and one or more pigmentable records each associated
with at least one
pigmentable waterborne paint composition of predictable transmissivity once
pigmented.
[0008] The third set of software instructions, when executed by the
processing module, may
further determine that the target reflectivity indicator for the vinyl panels
once painted the target
color is met by application of a self-standing pigmentable waterborne paint
composition. The
fourth set of software instructions, when executed by the processing module,
may then compute
the application procedure that identifies the self-standing pigmentable
waterborne paint
composition and the one or more proportioned paint pigments to achieve the
target the target
reflectivity indicator at the target color. Applying the self-standing
pigmentable waterborne
paint composition, once pigmented with the one or more proportioned paint
pigments, in such a
2
CA 2979100 2017-09-12

case, meets the target reflectivity indicator for the vinyl panels at the
target color. The non-
transitory memory may further comprise one or more self-standing pigmentable
records each
associated with at least one self-standing pigmentable waterborne paint
composition.
[0009] Optionally, the thickness indicator for the plurality of vinyl
panels may be a
thickness value measured physically at the site, evaluated visually at the
site, obtained from a
default thickness indicator associated with the paint application site,
determined considering a
current color of the vinyl panels and/or determined considering an unpainted-
color of the vinyl
panels.
[0010] The expert system may optionally further comprise a fifth set of
software
instructions, stored in the non-transitory memory, that, when executed by the
processing
module, obtain surface characteristics for the vinyl panels comprising sun
position data for
geographical coordinates of the painting site and geographical alignment value
of the vinyl
panels. Computing the target reflectivity indicator may then further be based
on the surface
characteristics.
[0011] The expert system may optionally further comprise a sixth set of
software
instructions, stored in the non-transitory memory, that, when executed by the
processing
module, compute an adjustment procedure for adjusting one or more of the
waterborne paint
compositions using one or more chemical compounds. Computing the adjustment
procedure
may yet further comprise computing an expected surface temperature value of
the vinyl panels
at an expected time of application.
[0012] The thickness indicator may provide a range thickness value for
thicknesses of one
or more of the vinyl panels and computing the target reflectivity indicator
may further comprise
matching the range thickness value with an acceptable reflectivity range
value.
[0013] In some embodiments, the one or more proportioned pigments may
each be
identified with a relative value established in relation to the pigmentable
waterborne paint
composition or the self-standing pigmentable waterborne paint composition.
Alternately or in
addition, the one or more proportioned pigments may each be identified with an
absolute
volumetric value established in relation to a volume of a container of the
pigmentable
waterborne paint composition or the self-standing pigmentable waterborne paint
composition.
[0014] The expert system may further compute a second application procedure
for the paint
application site for a different set of vinyl panels (e.g., different target
color and/or different
thickness or thickness indicator and/or different surface characteristics
(different sun
orientation, etc.)).
3
CA 2979100 2017-09-12

[0015] A second aspect of the present invention is directed to a method
for computing an
application procedure for painting vinyl panels a target color at a paint
application site while
preventing vinyl warping. The method comprises at a processing module of an
expert system,
obtaining a thickness indicator of the vinyl panels to be painted at the paint
application site
considering a request received from a remote device for the application
procedure. The method
continues with computing. at the processing module of the expert system, based
on the thickness
indicator and the target color for the vinyl panels, a target reflectivity
indicator for the vinyl
panels once painted for preventing vinyl warping before determining that the
target reflectivity
indicator for the vinyl panels once painted the target color is met by
application of multiple paint
layers of different paint compositions. Upon determination that the target
color is met by
application of the multiple paint layers, the method follows with computing
the application
procedure that identifies a pigmentable waterborne paint composition, one or
more proportioned
paint pigments to achieve a predictable transmissivity at the target color and
a preparatory
waterborne paint composition considering a corresponding predictable
reflectivity. Applying
the pigmentable waterborne paint composition, once pigmented with the one or
more
proportioned paint pigments, over the preparatory waterborne paint composition
meets the target
reflectivity indicator for the vinyl panels at the target color. The method
then follows with
sending instructions comprising the application procedure for painting the
vinyl panels at the
target color while preventing vinyl warping.
[0016] Optionally, the method may further comprise determining at the
processing module
that the target reflectivity indicator for the vinyl panels once painted the
target color may be met
by application of a self-standing pigmentable waterborne paint composition
considering
corresponding predictable reflectivity and, upon determination that the target
reflectivity
indicator at the target color is met by application of the self-standing
pigmentable waterborne
paint composition, computing the application procedure that identifies the
self-standing
pigmentable waterborne paint composition and the one or more proportioned
paint pigments to
achieve the target color. In such a case, applying the self-standing
pigmentable waterborne paint
composition, once pigmented with the one or more proportioned paint pigments,
meets the target
reflectivity indicator for the vinyl panels at the target color.
[0017] In some embodiments, the thickness indicator for the plurality of
vinyl panels is a
thickness value measured physically at the site, evaluated visually at the
site, obtained from a
default thickness indicator associated with the paint application site,
determined considering a
current color of the vinyl panels and/or determined considering an unpainted-
color of the vinyl
panels.
4
CA 2979100 2017-09-12

[0018] The method may also optionally comprise obtaining surface
characteristics for the
vinyl panels comprising sun position data for geographical coordinates of the
painting site and
geographical alignment value of the vinyl panels. Computing the target
reflectivity indicator is
then further based on the surface characteristics.
[0019] The method mat also optionally comprise computing an adjustment
procedure for
adjusting one or more of the waterborne paint compositions using one or more
chemical
compounds. Computing the adjustment procedure may then further comprise
computing an
expected surface temperature value of the vinyl panels at an expected time of
application.
[0020] The thickness indicator may provide a range thickness value for
thicknesses of one
or more of the vinyl panels and wherein computing the target reflectivity
indicator further
comprises matching the range thickness value with an acceptable reflectivity
range value.
[0021] In some embodiments, the one or more proportioned pigments may
each be
identified with a relative value established in relation to the pigmentable
waterborne paint
composition or the self-standing pigmentable waterborne paint composition.
Alternately, or in
addition, the one or more proportioned pigments may each be identified with an
absolute
volumetric value established in relation to a volume of a container of the
pigmentable
waterborne paint composition or the self-standing pigmentable waterborne paint
composition.
[0022] In some embodiments, the method may also compute a second
application procedure
for the paint application site for a different set of vinyl panels (e.g.,
different target color and/or
different thickness or thickness indicator and/or different surface
characteristics (different sun
orientation, etc.)).

invention will become

Detailed description
[0028] As previously mentioned, painted vinyl panels, after being
painted, sometimes have
a greater tendency to warp than unpainted vinyl panels. Conversely, it is
possible that some
unpainted vinyl panels that exhibited a tendency to warp react better after
being painted. Vinyl
panel warping, or vinyl warping, is defined in the context of the present
invention as a
deformation of the vinyl panel that is or would be perceptible to the eye when
the vinyl panel is
installed on a house or other structure. It has been noticed that certain
conditions of exposition
to the sun at different ambient temperature may cause vinyl warping. The
position of an eventual
visible deformation does not matter in the context of the present invention.
The general purpose
of the present invention is to minimize the risks of vinyl panel warping for
painted vinyl panels.
[0029] Thicker vinyl panels do not tend to exhibit vinyl warping, which
typically holds true
whether the vinyl panel is painted or not and also holds true no matter what
paint color is applied
to the vinyl panel. However, thinner vinyl panels have a higher tendency to
wrap, especially
when painted with darker colors. The thickness of the vinyl panel typically
varies between 0.035
inch and 0.055 inch (0.9mm to 1.4mm). Though advertising material sometimes
mention
thicknesses between 0.35mm and 0.55mm, it appears to be a mistaken measurement
unit these
would be too thin ¨ and are simply not sold on the market.
[0030] Research has been done from these observations to provide a paint
procedure that
would minimize, or would not increase, the likelihood of vinyl warping of
vinyl panels once
painted.
[0031] The heat stability of the vinyl used in common vinyl panels is
poor and the vicat
softening temperature is therefore typically low. Considering that the vicat
softening
temperature is constant for all vinyl panel thicknesses, it may be that
thicker vinyl panels support
higher temperature before exhibiting vinyl warping (e.g., general better
mechanical stability of
the thicker panels), but it appears more plausible that thicker panels present
a greater volume of
matter that can absorb more energy before reaching the vicat softening
temperature. In any case,
the ability of the vinyl panels to diffuse energy is critical.
[0032] Radiant energy is defined as energy of electromagnetic radiation in
the present
context, typically expressed in joules (J). Radiant exposure is defined as
radiant energy for a
surface per unit area, typically expressed in watts per square meters (J/m2 or
J=m-2). Radiant-
6
CA 2979100 2017-09-12

related values are also often expressed per unit of time (i.e., power-related
units instead or
energy-related units). Radiant flux (or radiant power) is defined as radiant
energy for a surface
per unit of area over a period of time. As radiant flux is a measure of power
(energy over time),
and not strictly a measure of energy, it is most often expressed in joules per
second (J/s or Js')
or watts (W). Irradiance is defined as radiant flux received by a surface per
unit area, typically
expressed in watts per square meters (W/m2, W=m-2, J/s.m2 or J=s-1.m-2).
Irradiance therefore
corresponds to the rate at which radiant flux is delivered onto a surface.
Radiant exitance is
defined as radiant flux delivered away from a surface per unit area or, said
differently, the rate
at which radiant flux is delivered away from a surface, typically also
expressed in watts per
square meters (W/m2, W=m-2, J/s.m2 or J=s-I=m-2). The radiant energy-related
concepts are
typically dependent upon the wavelength, or frequency, of the radiant energy,
which then define
a set of "spectral" values. The radiant energy-related concepts may also be
discussed from the
perspective of a point on a surface and a direction of propagation or
hemispherical propagation.
We will limit our discussion to the basic values as they appear sufficient for
the skilled person
to fully understand the teachings of the present invention.
100331 As the skilled person will note, radiant exitance is composed of
radiant flux reflected
by the surface (related to capacity to reflect energy of the surface or
reflectivity) and radiant flux
emitted by the surface (related to capacity to emit absorbed energy of the
surface or emissivity)
as well as radiant flux transmitted through the surface (related to capacity
to transmit energy of
the surface or transmissivity). In order for the temperature of the surface to
remain constant, the
irradiance must be equal to the radiant exitance. In the context of the
present discussion, the
radiant flux transmitted by the vinyl panels once painted is considered
negligible or constant
(see below) and only the reflected and emitted radiant flux components from
the radiant exitance
are considered.
[0034] In order to remain at constant temperature. irradiance and radiant
exitance from the
painted vinyl panels must be equal. In the context of the present invention,
it will be assumed
that all energy absorbed by the vinyl panels is converted into thermal energy
or, to the same
effect, that energy consumed by other processes in the vinyl panels is
negligible (e.g., color
change requires some energy, etc.). In that context, emitted energy from the
surface (related to
the radiant flux emitted) will correspond to the absorbed energy, as the
temperature would
otherwise raise. The capacity of a surface to emit radiant energy is referred
to as emissivity
(between 0% and 100%). If emissivity of a surface augments, the energy
absorbed by the surface
augments as well. The radiant flux reflected does not affect temperature of
the surface and, in
the context of the temperature ranges relevant to present discussion, is not
affected by the
7
CA 2979100 2017-09-12

temperature of the surface. The capacity of a surface to reflect radiant
energy is referred to as
reflectivity (between 0% and 100%). The capacity of a surface to transmit
radiant energy is
referred to as transmissivity (between 0% and 100%). Considering a constant or
irrelevant
transmissivity of the painted vinyl panels, it can be appreciated that
emissivity and reflectivity
are complementary. In order to limit the energy absorbed by the vinyl panels,
reflectivity should
be maximized, which implies that emissivity is to be minimized.
[0035] Emissivity, generally discussed only for the infrared spectrum, is
the ratio of the
radiant exitance from a surface to the radiant exitance from a perfect black
body at the same
temperature. Any material, at a given temperature, emits radiant energy in the
infrared spectrum.
A perfect blackbody absorbs all incoming radiant energy, and does not reflect
any. Said
differently, the radiant exitance of a perfect blackbody does not comprise any
reflected radiant
flux. Emissivity can have a value from 0 (e.g., shiny mirror) to 1.0 (perfect
blackbody). The
surface roughness and many different factors will affect emissivity of a
surface.
[0036] As a reference, from different sources, emissivity of "raw" vinyl
appears to vary
between 0.91 and 0.97 in the infrared spectrum. However, the emissivity of
painted plastic is
said to vary between 0.80 and 0.95. The present invention is focused on
properly considering
the effect of one or more paint compositions on reflectivity of painted vinyl
panels.
[0037] For the purpose of the present description, it is sufficient to
establish that the vinyl
panels are expected to exhibit a desired color after being painted (e.g.,
radiant exitance in the
visible spectrum from the perspective of the human eye, mainly reflected)
while being able to
diffuse (e.g., radiant exitance mainly in the infrared spectrum; reflected,
emitted and
transmitted) enough of the irradiance to maintain desired heat stability
(e.g., controlled vinyl
warping). It will also be assumed that the vinyl panels have a negligible
radiant flux transmitted
therethrough or, to the same effect, that the radiant flux transmitted remains
constant for given
thicknesses of the vinyl panels, no matter the type of paint composition(s)
and number of paint
layers applied thereon. The visible spectrum of the radiant exitance will not
be analyzed further
herein and it will be assumed that the skilled person will be able to
determine the proper
pigmentation to use in relevant paint compositions. However, potential effect
on the radiant
exitance, in the infrared spectrum, of the pigmentation and other component
used in one or more
of the paint compositions will be analyzed.
[0038] As previously discussed, different paint compositions, exhibit
different emissivity.
Transmissivity and reflectivity also vary between paint compositions. Within
certain limits, it is
possible to control emissivity, transmissivity and/or reflectivity of a paint
composition. While
8
CA 2979100 2017-09-12

transmissivity is considered constant or negligible for the vinyl panels once
painted, it is not
considered negligible for different layers of paint compositions applied on
the vinyl panels. In
fact, it has been determined that applying a layer of preparatory waterborne
paint composition
having a predictable reflectivity value before a applying a layer of pigmented
waterborne paint
composition having a predictable transmissivity value provides a resulting
painted surface over
the vinyl panels that has predictable reflectivity and emissivity values, with
transmissivity of the
painted vinyl panels, then, being considered negligible.
[0039] The present invention generally relates to systems and methods for
computing an
application procedure for painting vinyl panels a target color at a paint
application site while
preventing vinyl warping and/or for determining characteristics of pigmented
waterborne paint
compositions for preventing vinyl warping and/or for identifying proper
pigmented waterborne
paint compositions for preventing vinyl warping. In the context of the present
invention, at least
one preparatory waterborne paint composition is provided having a predictable
reflectivity and
more than two pigmented waterborne paint compositions, with different
pigments, are provided
having a predictable transmissivity once applied over a preparatory layer.
[0040] The present invention relies on the possibility ofpredictably
establish the reflectivity
of vinyl panels once painted by selecting one or more paint compositions
applied thereon. One
or more paint pigments are used in one or more layer to reach that the target
color. The paint
pigments are typically categorized as reflective ("solar reflective") or
transmissive ("solar
transparent"). Depending on the intended use of the paint composition once
pigmented, the
selection of the right pigments in the right quantity or proportion can be
established. The method
and system allow for determination of a target reflectivity (e.g., expressed
as an indicator or as
a value) for the painted vinyl panels at the target color considering
thickness of the vinyl panels
(e.g., thickness indicator expressed as a thickness value, range thickness
value, etc.). The target
reflectivity value is determined at least considering the thickness of the
vinyl panels and may
also be influenced by the target color.
[0041] From the target reflectivity, the method and system allow for
determination as to
whether the target reflectivity can be obtained using a single layer from a
single paint
composition (referred to hereinafter as a "self-standing" pigmentable paint
composition). For
instance, the target reflectivity may be achieved by adjusting a starting
exterior waterborne paint
composition into the self-standing paint composition using one or more
chemical compounds
(e.g., provided with the paint pigments or separately). In other embodiments,
different self-
standing paint compositions can be provided with different resulting
reflectivity (e.g., depending
on pigments) and a selection can be made between them. In certain
circumstances, it may be
9
CA 2979100 2017-09-12

preferable to rely on more than one layer of paint compositions. For instance,
it may be that the
target reflectivity cannot be met by a single layer or would be more difficult
to meet with a
single layer. It may be that the target reflectivity cannot be met because of
the extent of the
adjustment required, which would provide a paint composition that is
inefficient, undesired or
simply unworkable (e.g., characteristics of the paint composition such as flow
characteristics
(or fluidity) incompatible with application equipment(s), paint application
conditions at the paint
application site not compatible with required drying characteristics or
hardening properties,
etc.). It may also be that the target color can more predictably be achieved
using two layers. The
customer at the paint application site may also insist, for good or bad
reasons, on more than one
layer being applied. It may also be more cost-effective to apply two layers
(e.g., considering the
cost of the self-standing paint composition and/or of equipment required
considering the self-
standing paint composition or the likelihood of having to redo the painting
considering warranty
conditions. etc.)
[0042] When it is determined that two or more layers of paint
compositions are to be applied
on the vinyl panels to meet the target reflectivity at the target color,
proper preparatory and
pigmentable paint compositions are selected. It should be noted that the
preparatory paint
composition may also be pigmentable, but it has not been mentioned in every
case for the sake
of simplicity and readability of the present description. As mentioned
previously, one or more
paint pigments are used to obtain the target color in the right quantity or
proportion. The
selection of the proper pigmentable paint composition is made considering
transmissivity
characteristics thereof once pigmented when applied over the preparatory
layer. The selection
of the proper preparatory paint composition is made considering the
reflectivity potential when
the preparatory layer is covered by the pigmentable paint composition once
pigmented.
Essentially, when the preparatory paint composition and the colored
pigmentable paint
composition are applied successively, the vinyl panels will meet the target
reflectivity at the
target color.
[0043] In some embodiments, the self-standing paint composition, the
preparatory paint
composition and/or the pigmentable paint composition may be adjusted by
selectively adding
one or more chemical compounds in order to obtain adjusted waterborne paint
composition(s)
(e.g., pigmentable or not; self-standing or not; preparatory or not). The
adjustment may be made
for adjusting transmissivity and reflectivity thereof considering the target
reflectivity once the
vinyl panels are painted. The adjustment to transmissivity and reflectivity
may be made, in that
regard, by the paint pigment themselves and/or by specific chemical compounds.
The
adjustment may also be made, additionally or alternatively, for other reasons
related to the
CA 2979100 2017-09-12

expected application conditions at the paint application site (e.g., weather
conditions for the
application day and/or time).
[0044] Final proportion(s) of the added chemical compound(s) may be set
within
established tolerance intervals. A usual volume of starting exterior
waterborne paint
composition may be used to determine an actual volume to be added for each
chemical
compound. Different starting exterior waterborne paint compositions may also
be provided and
the method and system may therefore indicate which one of the starting
exterior waterborne
paint compositions is to be used and whether it is to be used without
modification or actual
volume(s) to be added for one or more chemical compounds.
[0045] The expected conditions comprise exterior substrate identification
data (which
comprise different types of vinyl compositions), environmental conditions
expected for a
predetermined application day and/or time at which the paint composition(s)
are expected to be
applied. The expected conditions may also comprise application equipment
characteristics (e.g.,
spray, brush, and roller), geographical characteristics of the exterior
surface including spatial
alignment thereof. The environmental conditions may be obtained from
forecast(s) and/or actual
measurement(s). Examples of environmental conditions include weather
conditions (e.g., air
temperature and/or surface temperature, wind speed and direction, relative
humidity and cloud
coverage) and sun position. In some embodiments, the expected conditions are
determined only
once and, accordingly, the paint composition(s) may be selected/adjusted once.
In other
embodiments, the expected conditions are determined more than once (e.g., 24
hours before the
application, when arriving on site and at the time of the application) and the
paint composition(s)
may then be adjusted more than once (while the paint composition(s) may be
selected only once
when more than one is available). As conditions change during application, the
paint
composition(s) may sometimes be adjusted again during application.
[0046] Reference is now made to the drawings, in which Figure 1 shows a
logical modular
view of an exemplary expert system 1100 is depicted. The expert system 1100 is
for computing
an application procedure for painting vinyl panels a target color at a paint
application site while
preventing vinyl warping. The expert system comprises a processing module
1130, a memory
module 1120 and a storage system 1500. In the depicted embodiment of Figure 1,
a networked
group of computers 1000 comprises the expert system 1100. The networked group
of computers
1000 is depicted with additional remote devices 1200 and 1300 that may send
one or more
request to the expert system 1100. The remote devices and the expert system
1100, 1200 and
1300 may be connected via a network 1400, via direct connections or a mix of
direct and network
connections. Various network links may be implicitly or explicitly used in the
context of the
11
CA 2979100 2017-09-12

present invention. While a link may be depicted as a wireless link, it could
also be embodied as
a wired link using a coaxial cable, an optical fiber, a category 5 cable, and
the like. A wired or
wireless access point (not shown) may be present on links. Likewise, any
number of routers
and/or switches (not shown) may be present on links, which may further transit
through the
Internet.
[0047] The processing module(s) 1130, 1230 and/or 1330 may represent a
single processor
with one or more processor cores or an array of processors, each comprising
one or more
processor cores. The memory module 1120 may comprise various types of memory
(different
standardized or kinds of Random Access Memory (RAM) modules, memory cards,
Read-Only
Memory (ROM) modules, programmable ROM, etc.). The network interface module
1140
represents at least one physical interface that can be used to communicate
with other network
nodes. The network interface module 1140 may be made visible to the other
modules of the
computer system 1100 through one or more logical interfaces. The actual stacks
of protocols
used by the physical network interface(s) and/or logical network interface(s)
1142, 1144, 1146,
1148 of the network interface module 1140 do not affect the teachings of the
present invention.
The variants of processing module 1130, memory module 1120 and network
interface module
1140 usable in the context of the present invention will be readily apparent
to persons skilled in
the art.
[0048] A bus 1170 is depicted as an example of means for exchanging data
between the
different modules of the computer system 1100. The present invention is not
affected by the
way the different modules exchange information between them. For instance, the
memory
module 1120 and the processing module 1130 could be connected by a parallel
bus, but could
also be connected by a serial connection or involve an intermediate module
(not shown) without
affecting the teachings of the present invention.
[0049] Likewise, even though explicit mentions of the memory module 1120
and/or the
processing module 1130, or explicit mentions of other modules in the computer
systems 1200
and 1300, are not made throughout the description of the various embodiments,
persons skilled
in the art will readily recognize that such modules are used in conjunction
with other modules
of the computer system 1100, 1200 and/or 1300 to perform routine as well as
innovative steps
related to the present invention. Similarly, two systems 1100 and 1200 or 1300
may be involved
for obtaining an adjusted exterior waterborne paint composition for an
exterior surface to be
painted at a paint application site.
12
CA 2979100 2017-09-12

[0050] In some embodiments, the expert system 1100 may comprise a
dedicated paint
compositions module 1132 dedicated to storing paint composition data and/or
computing paint
compositions. In other embodiments, alternatively or in addition, functions of
the paint
compositions module 1132 are shared with the processing module 1130 and the
storage system
1500 (e.g., the paint compositions module 1132 is a sub-module ofthe
processing module 1130).
For instance, the paint composition module may comprise and/or manage access
to data records
for one or more paint compositions. The data records may comprise predictable
reflectivity
and/or predictable transmissivity, which may be expressed as ranges or maximum
values and/or
associated with pigmentation information (e.g., different
reflectivity/transmissivity ranges for
different pigments or pigment ranges). In some embodiments, the data records
may also
comprise resin chemistry data, surfactants characteristics, wetting agents
characteristics and/or
flow agents characteristics. The paint composition module may also comprise
and/or manage
access to data records each associated with a paint pigment having a
pigmentation identifier.
The data records associated with the paint compositions and/or the pigments
may comprise one
or more tolerance values for relative humidity in relation to temperature
(e.g., air temperature
or surface temperature). For instance, the tolerance values may be expressed
as a range of
relative humidity and temperatures that represent for proper application
conditions for the paint
composition. The tolerance values may comprise more than one range (e.g.,
recommended
conditions, acceptable conditions, non-acceptable conditions). The tolerance
values are set in
order to maintain appropriate characteristics of the paint composition. The
appropriate
characteristics comprise transmissivity and/or reflectivity of the paint
composition and may also
comprise, in certain embodiments, flow characteristics (i.e., avoid low flow
and excessive flow)
and drying characteristics of the paint composition (i.e., allow a film to
appropriately form and
appropriately adhere to the vinyl panels).
[0051] In some embodiments, the expert system 1100 may comprise a dedicated
application
conditions module 1134 dedicated to storing, computing and/or obtaining
application conditions
data. In other embodiments, alternatively or in addition, functions of the
application conditions
module 1134 are shared with the processing module 1130 and the storage system
1500 (e.g., the
application conditions module 1134 is a sub-module of the processing module
1130).
Application conditions data include a thickness indicator for the vinyl panels
on which the paint
composition(s) is to be applied. The thickness indicator may be expressed as
thickness value
and/or a thickness value range for purposes of computation, but may also be
presented on a scale
(e.g., 1 to 5), which may be sufficient for the purpose of the computation
and/or desired for the
purpose of simplifying the computation. The thickness value or thickness value
range may be
13
CA 2979100 2017-09-12

measured at the paint application using a direct physical measurement tool
local to the remote
device 1200, 1300 (e.g., a caliper). The thickness value or thickness value
range may also be
evaluated visually at the site (e.g., by experience of the painter at the
paint application site). The
thickness value or thickness value range may also be associated with the type
of the vinyl panels
(e.g., using a trade-mark or other specific sign) leading to the thickness
value or range value
(e.g., after a lookup in one or more database that may or may not be part of
the storage system
1500). The thickness value or thickness value range may also be obtained from
a default
thickness indicator associated with the paint application site (e.g.,
information provided by the
customer at the paint application site and available to the expert system).
The thickness value or
thickness value range may also be determined considering a current color of
the vinyl panels
and/or determined considering an unpainted-color of the vinyl panels. More
than one source of
thickness data may also be used to come to a final determination of the
thickness indicator from
multiple values or value ranges. In some embodiments, when the thickness
indicator cannot be
readily obtained or may be obtained without sufficient confidence, a default
thickness value may
be set that corresponds to the thinnest possible vinyl panel that could be
present at the paint
application site (e.g., considering year of installation, color, trademark /
type of panel, etc.).
[0052] Application conditions data may also comprise environmental
conditions data
including weather conditions such as maximum air temperature applicable for
the paint
application site (e.g., obtained from historical data). Other environmental
conditions data may
also include wind speed and direction, relative humidity and cloud coverage as
well as and sun
position. When application conditions for a specific date are also to be
considered, the
application conditions module 1134 may obtain forecast(s) of relevant
environmental conditions
(e.g., interacting through the network interface module 1140 with a remote
forecast provider)
and/or actual measurement(s) of relevant environmental conditions (e.g.,
interacting with one
or more instruments (not shown) local to the expert system 1000, local to the
remote 'device
1200, 1300 and/or remote to both the expert system 1100 and the remote device
1200, 1300).
The application conditions module 1134 may also store and/or compute
temperature data for the
vinyl panels to be painted. For instance, surface temperature may be computed,
measured
directly, or measured directly and thereafter computed to provide an expected
variability for a
period of time such as a range of temperatures, a maximum value (e.g., when
application is
expected while air temperature is rising and/or sun is rising) and/or minimum
value (e.g., when
application is expected while air temperature is dropping and/or sun is
setting).
100531 Figure I also shows examples of the storage system 1500 as a
distinct database
system 1500A, a distinct module 1500B of the computer system 1100, a sub-
module 1500C of
14
CA 2979100 2017-09-12

the memory module 1120 of the computer system 1100, a sub-module 1500D of the
paint
compositions module 1132 of the computer system 1100 or a sub-module 1500E of
the
application conditions module 1134 of the computer system 1100. The storage
system 1500 may
be distributed over different systems A, B, C, D and/or E or may be in a
single system. The
storage system 1500 may comprise one or more logical or physical as well as
local or remote
hard disk drive (HDD) (or an array thereof). The storage system 1500 may
further comprise a
local or remote database made accessible to the computer system 1100 by a
standardized or
proprietary interface or via the network interface module 1140. The variants
of storage system
1500 usable in the context of the present invention will be readily apparent
to persons skilled in
the art.
[0054] Reference is now concurrently made to Figure 1 and Figure 2, which
show a flow
chart of an exemplary method 2000 for computing painting vinyl panels a target
color at a paint
application site while preventing vinyl warping. The method 2000 comprises
obtaining 2010
obtaining a thickness indicator of the vinyl panels to be painted at the paint
application site by
the processing module 1130 of the expert system 1100. In some embodiments,
environmental
conditions may also be obtained for the paint application site as explained in
greater details
elsewhere in the present disclosure in relation to optional features of the
present invention. As
previously explained, the thickness indicator may be obtained 2010,
alternatively or in addition,
from one or more actual measurements at the paint application site. The
thickness indicator and,
when relevant, environmental conditions may be stored and retrieved and/or
computed through
the application conditions module 1134 of the expert system 1130.
[00551 In some embodiments, the thickness indicator is obtained 2010 only
after receiving
2002 a request for the paint application procedure from a remote device 1200,
1300 through the
network interface module 1140. The expert system 1100 may obtain 2010 the
thickness indicator
partly or completely from the remote device 1200, 1300 (e.g., in the received
2002 request or in
association with the received 2002 request). For instance, one or more
instruments (not shown)
local to the remote device 1200, 1300, may be used in order to obtain the
thickness indicator.
The instrument may be in communication with the remote device 1200/1300 (e.g.,
short range
wireless such as Bluetooth or wired) or the expert system 1100 (long range
wireless such as
WIFI or LTE or wired) or may simply be read by a user to input a value into
the Graphical user
interface of the remote device 1200/1300. The instrument may also be
integrated with the remote
device 1200, 1300 or connected via a wire to the remote device 1200, 1300.
[00561 The thickness indicator may be obtained 2010 for a single one of
the vinyl panels or
multiple determination (e.g., measurements) may be made. The thickness
indicator obtained
CA 2979100 2017-09-12

2010 may therefore be a mean values, minimum values and/or maximum values for
the vinyl
panels. In certain embodiments, different sets of vinyl panels may be
determined and treated
separately from the perspective of the method 2000 (e.g., different
thicknesses, different target
color, different geographical alignment, different original color or material,
etc.). For instance,
the minimum thickness value may be used for the paint application site to
obtain 2010 the
thickness indicator, thereby ensuring that the target reflectivity will be set
for the worst case
scenario.
100571 Once the thickness indicator is obtained 2010 for the paint
application site at the
geographical coordinates for the specific date by the processing module 1130
of the expert
system 1100, the method 2000 follows with step 2020. In the step 2020, the
processing module
1130 of the expert system 1100 computes 2020 a target reflectivity indicator
for the vinyl panels
once painted in order to prevent vinyl warping. Of course, the computing 2020
may focus on
emissivity instead of reflectivity, as the skilled person will acknowledge
from the previous
discussion on the subject. The computing 2020 is based on the thickness
indicator previously
obtained and the target color for the vinyl panels. The maximum air
temperature expected at the
application site throughout a typical year may also be considered during the
computing 2020. A
maximum expected irradiance for the vinyl panels may be computed (not shown)
considering
sun position data for geographical coordinates of the paint application site
and/or geographical
alignment value of the vinyl panels to be painted. The geographical alignment
value of the vinyl
panels, or a subset of the vinyl panels, may be provided with different
degrees of granularity.
For instance, the granularity may be limited to North, South, East or West (or
closest 90 ). As
skilled person will recognize, the granularity could be set anywhere between
high precision (to
1 , 50, 10 , etc.) up to 90 .
[0058] More precise substrate identification data for the vinyl panels
may optionally be
relied upon during the computing 2020 (e.g., specific type of PVC). The
computing 2020 of the
target reflectivity indicator may involve a more detailed computation (not
shown) of specific
emissivity value for the vinyl panels once painted the target color. The
emissivity may be
obtained from a lookup (not shown) into one or more database that may or may
not be part of
the storage system 1500. In some embodiments, the emissivity database(s) is be
built with time
(based on results / feedback from past paint jobs) by the expert system 1000
acting as a learning
system. In some embodiments, the emissivity may also be computed by
extrapolating from
existing emissivity data (e.g., exact target color emissivity may be unknown
but may be
computed/interpolated from different "higher" and "lower" tones around the
target color).
16
CA 2979100 2017-09-12

[0059] Skilled persons will recognize that the detailed substrate
identification data may be
obtained from one or more default values (i.e., the expert system 1100 is
compatible with a
single type of substrate or only one type of substrate at a time), may be
provided in the received
request 2002 or may otherwise be obtained by the expert system 1100 for the
paint application
site (e.g., provided by the customer or in database of historical contracts).
[0060] In some embodiments, emissivity / reflectivity of the vinyl panels
may be obtained
(not shown) through direct testing. The direct testing may be performed as an
empirical step for
building a database of relevant data or as an additional validation step (not
shown) in the context
of the present invention. Tests may be performed on a portion of the vinyl
panels themselves at
the application site or on a section panel identical in characteristics to the
vinyl panels (e.g., test
performed at the application site or remote thereto. For instance, extra
section panel(s) for the
paint application site or section panel(s) known to have the same
characteristics may be sued for
testing. The test may be performed prior to painting of the test panel (raw
capacity), after
application of one or more paint layers in accordance with the method 2000
(i.e., validation) or
after application of one or more paint layers in accordance with different
procedures (i.e., test).
The test may involve measurement of the actual temperature of the test panel
(e.g., surface
temperature from a contact thermometer) and knowledge of the applicable
maximum
temperature for the test panel before exhibiting vinyl warping (i.e., vicat
softening temperature).
For instance, an instrument may be applied to a relevant portion of the test
panel. When the test
is performed at the application site, the instrument may be in communication
with the remote
device 1200/1300 (e.g., short range wireless such as Bluetooth or wired) or
the expert system
1100 (long range wireless such as WIFI or LTE or wired) or may simply be read
by a user to
input a value into the Graphical user interface of the remote device
1200/1300. The test panel is
submitted to controlled irradiance. The temperature of the test panel, once
stabilized, may be
measured. It is possible to determine whether the test panel exhibits vinyl
warping once the
controlled irradiance reaches the expected maximum irradiance at the paint
application site or
to limit the controlled irradiance before the vicat softening temperature is
reached. Alternately,
or in addition, maximum irradiance tolerated by the test panels before
exhibiting vinyl warping
may be determined (e.g., considering the measured temperature or when the test
panel actually
exhibits vinyl warping (destructive test)).
[0061] After computing 2020 of the target reflectivity indicator, the
method 2000 then
continues by determining 2030 at the processing module 1130 of the expert
system 1100 that
the target reflectivity indicator for the vinyl panels once painted the target
color is met by
application of multiple paint layers of different paint compositions. The
determination 2030 may
17
CA 2979100 2017-09-12

be made by the expert system 1000 because the target reflectivity cannot be
met, or can only be
met with difficulty, by a single layer. fhe expert system 1000 may rely on one
or more data
records from the storage module 1500 that allow for the computation or
determination of a
maximum predictable reflectivity for a self-standing waterborne paint
composition for the target
color (e.g., after adjustment using one or more chemical compounds or as is).
For instance, if
the maximum predictable reflectivity is lower than the target reflectivity,
then more than one
layer is required. As mentioned previously, other reasons may allow to
determine that more than
one layer is required (the target color can more predictably be achieved using
two layers,
customer request, cost-effectiveness, warranty conditions, etc.) Upon
determination 2030 that
the target reflectivity at the target color is met by application of the
multiple paint layers, the
method 2000 continues with the processing module 1130 of the expert system
1000 computing
2040 the application procedure accordingly. That is, the computing 2040
identifies a
pigmentable waterborne paint composition considering a predictable
transmissivity, one or more
proportioned paint pigments to achieve the target color at the predictable
transmissivity and a
preparatory waterborne paint composition considering a corresponding
predictable reflectivity.
The computing 2040 is done such that applying the pigmentable waterborne paint
composition,
once pigmented with the one or more proportioned paint pigments, over the
preparatory
waterborne paint composition meets the target reflectivity indicator for the
vinyl panels at the
target color. The computing 2040 may rely on the storage module 1500 having
one or more
preparatory records each associated with one preparatory waterborne paint
composition, having
one or more pigmentable records each associated with at least one pigmentable
waterborne paint
composition and a plurality of pigment records each associated with a paint
pigment having a
pigmentation identifier. In some embodiments, a single preparatory paint
composition may be
provided with a predictable reflectivity value. However, the effective
reflectivity of the vinyl
panels once paintcd may depend on characteristics of the pigmentable paint
composition and of
the one or more proportioned pigments therein. The data records may provide
one or more range
values for the transmissivity/reflectivity considering pigmentation. The data
records may also
provide the range values for the pigmentable paint composition that vary
depending on the
characteristics of the preparatory paint composition (e.g., reflectivity
characteristics, flow
characteristics and/or drying characteristics).
[0062] Optionally, the determination 2030 made by the processing module
1130 may be
that the target reflectivity indicator for the vinyl panels once painted the
target color may be met
by application of a self-standing pigmentable waterborne paint composition
considering
corresponding predictable reflectivity. In such cases, the method 2000 then
continues with
18
CA 2979100 2017-09-12

computing 2045 the application procedure that identifies the self-standing
pigmentable
waterborne paint composition the one or more proportioned paint pigments to
achieve the target
color considering corresponding predictable transmissivity. The computing 2045
is done such
that applying the self-standing pigmentable waterborne paint composition, once
pigmented with
the one or more proportioned paint pigments, meets the target reflectivity
indicator for the vinyl
panels at the target color. The computing 2045 may rely on the storage module
1500 having on
one or more self-standing pigmentable records each associated with at least
one self-standing
waterborne paint composition of predictable transmissivity. The data records
may provide one
or more range values for the reflectivity considering pigmentation.
[0063] The method 2000 then follows with sending 2050 instructions
comprising the
application procedure for painting the vinyl panels at the target color while
preventing vinyl
warping.
[00641 The application procedure may also specify (not shown) one or
more chemical
adjustment compounds to be added to the paint composition(s) before the
application on the
vinyl panels. For instance, the application procedure may provide one or more
volumetric values
for one or more corresponding adjustment compounds. The method 2000 may also
comprise
obtaining (not shown) a volume of a container for the paint composition and
the application
procedure may comprise absolute volumetric values for each the corresponding
adjustment
compounds. For instance, the adjustment compounds may comprise a surfactant or
wetting agent
for adjusting surface tension characteristics of the paint composition and/or
a flow agent for
adjusting levelling characteristics of the paint composition. Some other
adjustment compounds
may include rheology agent or rheology modifier (e.g., paint thickener) and
coalescing solvents
or filming agents (e.g., hydrophilic solvent, hydrophobic solvent). Different
wetting, flow,
rheology and/or filming agents (e.g., even from the same agent type, but
having different
"strength", premix of different agents, etc.) may alternatively or
concurrently be specified in the
application procedure.
[0065] In some embodiments, the application procedure provides a
suggested duration of a
mixing or shaking operation appropriately mixing the paint composition, e.g.,
following
addition of the adjustment compounds. The suggested duration may be set by
default or may be
computed by the processing module 1130 of the expert system 1100 considering
the adjustment
compounds added and/or total volume added (e.g., relative or absolute values).
In some
embodiments, the one or more proportioned pigments may each be identified with
a relative
value established in relation to the pigmentable waterborne paint composition
or the self-
standing pigmentable waterborne paint composition. Alternately, or in
addition, the one or more
19
CA 2979100 2017-09-12

proportioned pigments may each be identified with an absolute volumetric value
established in
relation to a volume of a container of the pigmentable waterborne paint
composition or the self-
standing pigmentable waterborne paint composition.
[0066] The method 2000 may also optionally comprise associating (not
shown) a tolerance
interval with each ofthe radiology characteristics (transmissivity,
reflectivity and/or emissivity).
[0067] In some embodiments, the method 2000 may be executed 2060 more
than once for
additional sets of vinyl panels to be painted at the paint application site.
The method 2000 may
therefore allow to select different paint compositions for the paint
application site, e.g., because
the target color is different and/or because of different surface
characteristics (e.g., different
geographical alignment value).
[0068] The method 2000 may also optionally comprise computing an
adjustment procedure
for adjusting one or more of the waterborne paint compositions using one or
more chemical
compounds. Computing the adjustment procedure may then further comprise
computing an
expected surface temperature value ofthe vinyl panels at an expected time of
application. Details
of this optional features are provided with reference to Figure 4 hereinbelow.
[0069] In some embodiments, the remote device 1200/1300 comprises a
graphical user
interface (not shown) for interacting with one or more users (not shown) and
may also be a
smartphone, a tablet, a phablet, a computer (e.g., portable or fixed to a
mobile unit) or other
multi-purpose processing device.
[0070] Figure 3 shows a flow and nodal operation chart in accordance with
an exemplary
system 3000 in accordance with an embodiment of the present invention for
providing
instructions to a user 3010 for painting vinyl panels a target color at a
paint application site while
preventing vinyl warping. The user 3010 has access to a mobile device 1200 and
a site-data
collection device 3020. Also, depicted in the example of Figure 3 are optional
weather provider
3030 and optional sun position provider 3040 as well as a paint adjustment
expert system 1100.
The mobile device 1200 may comprise the site-data collection device 3020
(e.g., as a sub-
module) or the site-data collection device 3020 may be a standalone device.
Likewise, weather
and sun position may be provided by external providers 3030 / 3040 as depicted
but may also
be provided completely or partially (e.g., validated by external providers) by
the mobile device
1200 and/or the site-data collection device 3020.
[0071] In the example of Figure 3, the user 3010 provides the mobile
device 1200 with
paint product data 3100. The paint product data may, for instance, identify
the target color of
for the vinyl panels as well as available paint compositions and pigments
(e.g., by trademark
CA 2979100 2017-09-12

and/or by chemical characteristics; providing volume or weight of paint,
etc.). The paint product
data may also comprise one or more available adjustment compounds (e.g., by
trademark and/or
by chemical characteristics). In some embodiments, the user 3010 may also
input a specific date
for the paint application or current date may be used. The user 3010 may also
input an expected
time for the paint application or current time may be used. The user 3010 may
also input (not
shown) a location for a paint application site. The location, date and/or time
may also be
obtained by the mobile device 1200 (e.g., using a GPS module thereof) and/or
by the site-data
collection device 3020 (e.g., using a GPS module thereof). Thickness of the
vinyl panels and
location of the paint application site as well as additional information
concerning the paint
application site (e.g., number of exterior surfaces, detailed substrate
identification, alignment of
exterior surfaces, etc.) may also be provided by the user 3010 and/or
retrieved (not shown) from
a database storing site-specific information. The location or another
identifier (civic address,
client name, etc.) may be used to retrieve the site-specific data from the
database storing site-
specific information.
[0072] In some embodiments, the user 3010 requests environmental conditions
data 3110
to the site-data collection device 3020. The site-data collection device 3020
may then obtain
data from the weather provider 3030 and the sun position provider 3040 before
returning the
requested environmental conditions data. The user 3010 may also directly
request (not shown)
the weather data from the weather data provider 3030 and the sun position data
from the sun
position provider 3040. In these embodiments, the user 3010 then provides the
obtained
environmental conditions data to the mobile device 1200 in a request for paint
advice 3200.
[0073] Alternatively to obtaining the environmental conditions data by
the user 3010, the
user 3010 may send the request for paint advice 3200 without environmental
conditions data.
As a first option, the mobile device 1200 may then request 3114 environmental
conditions data
from the site-data collection device 3020, the weather provider 3030 and the
sun position
provider 3040. The mobile device 1200 may alternatively request the
environmental conditions
data (not shown) from the site-data collection device 3020, which may then in
turn obtain data
from the weather provider 3030 and the sun position provider 3040 before
returning the
requested environmental conditions data. The mobile device 1200 then sends a
request 3222 for
paint advice to the paint adjustment expert system 1100 with the obtained
environmental
conditions data. As a second option, the mobile device 1200 may send a request
3220 for paint
advice to the paint adjustment expert system 1100 without environmental
conditions data. The
paint adjustment expert system 1100 may then request 3112 environmental
conditions data from
the site-data collection device 3020. the weather provider 3030 and the sun
position provider
21
CA 2979100 2017-09-12

3040. The paint adjustment expert system 1100 may alternatively request the
environmental
conditions data (not shown) from the site-data collection device 3020, which
may then in turn
obtain data from the weather provider 3030 and the sun position provider 3040.
[0074] The paint adjustment expert system 1100 may receive (not shown) a
specific date of
application and/or an expected time of application or may alternatively, or by
default if none are
received, use the current date and time. A default time may also be
predetermined (e.g., noon)
or only the specific date without expected time may be used by the paint
adjustment expert
system 1100. The paint adjustment expert system 1100 may also obtain (not
shown) a location
for a paint application site (e.g., from a database storing site-specific
information, from the
mobile device 1200 (e.g., using a GPS module thereof) and/or by the site-data
collection device
3020 (e.g., using a GPS module thereof)). The location of the paint
application site as well as
additional information concerning the paint application site (e.g., number of
exterior surfaces,
detailed substrate identification, alignment of exterior surfaces, etc.) may
also be obtained (not
shown) by the paint adjustment expert system 1100 from the database storing
site-specific
information. The location or another identifier (civic address, client name,
etc.) may be used to
retrieve the site-specific data from the database storing site-specific
information.
[0075] Once the paint adjustment expert system 1100 obtains the thickness
indicator for the
vinyl panels, an application procedure is computed by the paint adjustment
expert system 1100.
Optionally, the environmental conditions data together with location and other
relevant
information for the paint application site may be used to compute an
adjustment procedure.
Instructions are then sent 3300 therefrom towards the mobile device 1200
comprising the
application procedure and, optionally, the adjustment procedure, for painting
vinyl panels a
target color at a paint application site while preventing vinyl warping. The
mobile device 1200
then provides the instructions 3310 to the user 3010 (e.g., using a Graphical
User Interface (GUI)
thereof). As mentioned with reference to other examples, some or all of the
steps depicted on
Figure 3 may be repeated for different application sites, repeated for
different surfaces at a single
paint application site and/or repeated for a single surface at different time.
[0076] Reference is now concurrently made to Figure 1 and Figure 4, which
show a flow
chart of an exemplary method 4000 for computing an adjustment procedure for
transforming a
starting exterior waterborne paint composition (e.g., the pigmentable paint
composition or self-
standing paint composition previously discussed) comprising a plurality of
base chemical
compounds into an adjusted exterior waterborne paint composition for an
exterior surface to be
painted on a specific date. A base value is associated with each one of the
plurality of base
chemical compounds in the starting exterior waterborne paint composition.
22
CA 2979100 2017-09-12

[0077] The method 4000 comprises obtaining 4010 environmental conditions
for a paint
application site at geographical coordinates for the specific date by the
processing module 1130
of the expert system 1100. The environmental conditions comprise relative
humidity data for
the geographical coordinates and temperature data for the geographical
coordinates. The
environmental conditions may also comprise sun position data, expected cloud
coverage data
and/or wind speed value and wind direction or orientation value. The
environmental conditions
may be obtained 4010 from a weather forecast provider (e.g., government
agency, public or
private weather network, etc.). The environmental conditions may be obtained
4010
alternatively or in addition from a weather instruments and/or actual
measurements. The
environmental conditions may also be obtained 4010 by computing data stored at
the expert
system 1100 and/or retrieved from the forecast provider and/or measurements by
the expert
system 1100 (e.g., sun position data may be computed from historical data and
dew point may
be computed from the relative humidity and temperature value). Skilled person
will readily
acknowledge that providing the dew point for the specific date may be
sufficient to compute the
relevant relative humidity data. The environmental conditions may be stored
and retrieved
and/or computed through the application conditions module 1134 of the expert
system 1130.
10078.1 In some embodiments, the environmental conditions are obtained
4010 only after
receiving 4002 a request for the adjustment procedure from a remote device
1200, 1300 through
the network interface module 1140. The expert system 1100 may obtain 4010 the
environmental
conditions partly or completely from the remote device 1200, 1300 (e.g., in
the received 4002
request or in association with the received 4002 request). For instance, one
or more instruments
(not shown) of the remote device 1200, 1300 may be used in order to obtain at
least some of the
environmental conditions. Alternatively, or in addition, the remote device
1200, 1300 may
communicate with the weather forecast provider (e.g., government agency,
public or private
weather network, etc.) and/or networked weather instruments to obtain some or
all of the
environmental conditions. The temperature data may also be represented by a
temperature range.
[0079] The environmental conditions may be obtained 4010 for a default
time on the
specific date (e.g., noon). The environmental conditions may be obtained 4010
as mean values,
minimum values and/or maximum values for the specific date or for one or more
time periods
on the specific date. For instance, the minimum and maximum temperature values
may be
obtained, the minimum and maximum relative humidity values may be obtained
while only the
maximum speed value is obtained and only the mean wind orientation value is
obtained. When
the environmental conditions are obtained 4010 for short time periods on the
specific date (e.g.,
an hour or two hours), only means values may be required (e.g., mean values
every hour for the
23
CA 2979100 2017-09-12

specific date). The time period(s) may also correspond to the morning,
afternoon and/or night
on the specific date. The time periods may also be determined considering an
expected time of
application associated with one or more of the surfaces to be painted at the
paint application site.
For instance, different surfaces may be planned at different application times
on the specific
date and the different periods may be set in accordance with the expected
application times
(starting at 7:00AM, for 2 hours 4 surface A; starting on 7:20, for 4 hours 4
surface B, starting
at 12:00PM, for 6 hours 4 surface C, etc.). A maximum time period length may
also be set in
order to avoid too much gap between the highest and lowest values for one or
more of the
environmental conditions. For instance, each time period may be limited to 2
hours.
[0080] In some embodiments, the environmental conditions 4010 are obtained
only once
e.g., the day before the specific date (e.g., considering forecast only) or on
the specific date (e.g.,
considering forecast and/or measurements). In some embodiments, the
environmental
conditions 4010 are obtained more than once (e.g., on the day before the
specific date and on
the specific date). The adjustment procedure may be computed every time the
environmental
conditions are obtained 4010 or may be computed only when the environmental
condition(s)
obtained 4010 from one or more forecasts are determined to be reliable (e.g.,
considering
forecast fluctuations throughout the period of time or throughout the specific
date and/or
highest/lowest probability of precipitation value(s)).
[0081] Once the environmental conditions are obtained 4010 for the paint
application site
at the geographical coordinates for the specific date by the processing module
1130 of the expert
system 1100, the method 4000 follows with step 4020. In the step 4020, The
processing module
1130 of the expert system 1100 computing 4020 a target value for each of a
plurality of target
chemical compounds in an adjusted exterior waterborne paint composition for an
exterior
surface to be painted. The plurality of target chemical compounds are computed
4020 based on
the environmental conditions previously obtained 4010 and substrate
identification data for the
exterior surface to be painted. Specifically, the plurality of target chemical
compounds are
computed 4020 based at least on the relative humidity data for the specific
date for the
geographical coordinates, the temperature data for the specific date for the
geographical
coordinates and the substrate identification data for the specific date.
Computing 4020 the
plurality of target values each associated with one of the plurality of target
chemical compounds
in the adjusted exterior paint composition may also be performed considering
an expected time
of application for the specific date. Whenever relevant, the expected time of
application may be
determined from the period of times, used for obtaining 4010 the environmental
conditions or
vice-versa (i.e., the period of times being determined from the expected time
of application).
24
CA 2979100 2017-09-12

[0082] In some embodiments, the method 4000 may also comprise obtaining
(not shown)
surface characteristics for the exterior surface to be painted with the
adjusted exterior paint
composition at the paint application site. The surface characteristics
comprises the substrate
identification data and may further comprise sun position data for the
geographical coordinates,
a geographical alignment value of the exterior surface to be painted and an
actual and/or
expected surface temperature for the exterior surface to be painted. Skilled
persons will
recognize that the substrate identification data may obtained from one or more
default values
(i.e., the expert system 1100 is compatible with a single type of substrate or
only one type of
substrate at a time), may be provided in the received request 4002 or may
otherwise be obtained
by the expert system 1100 for the paint application site (e.g., provided by
the customer or in
database of historical contracts). The substrate identification data may be
associated to one or
more starting paint compositions. For instance, the substrate identification
data may comprise
identification of the exterior surface to be painted as being PVC cladding,
aluminum cladding,
wood, a pre-painted water-base surface, a pre-painted oil-base surface, etc.
Each of a plurality
of starting paint compositions may be associated to each of the substrates.
[0083] The geographical alignment value of the exterior surface may be
provided with
different degrees of granularity. For instance, the granularity main be
limited to North, South,
East or West (or closest 90 ). As skilled person will recognize, the
granularity could be set
anywhere between high precision (to 1 , 50, 10 , etc.) up to 90 .
[0084] Computing 4020 the plurality of target values each associated with
one of the
plurality of target chemical compounds in the adjusted exterior paint
composition may fitrther
comprise computing (not shown), at the processing module 1130 of the expert
system 1100, the
actual and/or expected surface temperature value of the surface
characteristics for the exterior
surface considering the relative humidity data at the geographical coordinates
and the
temperature data for the geographical coordinates. Actual temperature of the
surface to be
painted may be obtained by direct measurement. For instance, an instrument may
be applied to
a significant portion of the surface to be painted. The instrument may be in
communication with
the remote device 1200/1300 (e.g., short range wireless such as Bluetooth or
wired) or the expert
system 1100 (long range wireless such as WIFI or LTE or wired) or may simply
be read by a
user to input a value into the Graphical user interface of the remote device
1200/1300. Sun
position data, expected cloud coverage data and/or the expected time of
application may further
be considered by the expert system 1100 when computing the expected surface
temperature
value of the surface characteristics for the exterior surface to be painted.
Likewise, the wind
speed value at the geographical coordinates, the wind orientation value at the
geographical
CA 2979100 2017-09-12

coordinates and the geographical alignment value may be considered,
alternatively or in
addition, by the expert system 1100 when computing the expected surface
temperature value.
The expected surface temperature value may be represented by a temperature
range. The
temperature range may also be associated with a time range (e.g., between 23 C
and 26 C
between 10:00 and 12:00)
[0085] The method 4000 then continues by determining 4030 at the
processing module
1130 of the exert system 1100 whether one or more base values of the starting
exterior
waterborne paint composition is different from corresponding target values as
computed in 4020
by the expert system 1100. When the plurality of target values is determined
in 4030 to be
different from the plurality of base values, the method 4000 continues by
computing 4040, at
the processing module 1130 of the expert system 1100, an adjustment procedure
for
transforming the starting exterior waterborne paint composition into the
adjusted exterior paint
composition for the exterior surface to be painted. Once the procedure is
computed 4040, the
method continues with sending instructions 4050 to the remote device. The
instructions sent
4050 comprise the adjustment procedure for obtaining the adjusted exterior
waterborne paint
composition from the starting exterior waterborne paint composition for the
exterior surface to
be painted.
[0086] In some embodiments, the adjustment procedure provides one or more
volumetric
values for one or more corresponding adjustment compounds for the plurality of
target values
to be determined equivalent to the plurality of base values. The plurality of
target values may
be determined equivalent to the plurality of base values when each of the
plurality of base values
is within corresponding tolerance interval(s). The method may then also
comprise obtaining (not
shown) a volume of a container for the starting exterior paint composition and
the adjustment
procedure may be absolute volumetric values for each the corresponding
adjustment
compounds. For instance, the adjustment compounds may comprise a surfactant or
wetting agent
for adjusting surface tension characteristics of the adjusted paint
composition and/or a flow
agent for adjusting levelling characteristics of the adjusted paint
composition. Some other
adjustment compounds may include rheology agent or rheology modifier (e.g.,
paint thickener)
and coalescing solvents or filming agents (e.g., hydrophilic solvent,
hydrophobic solvent).
Different wetting, flow, rheology and/or filming agents (e.g., even from the
same agent type,
but having different "strength", premix of different agents, etc.) may
alternatively or
concurrently be specified in the adjustment procedure.
[0087] In some embodiments, the adjustment procedure provides a suggested
duration of a
mixing or shaking operation appropriately mixing the adjusted paint
composition following
26
CA 2979100 2017-09-12

addition of the adjustment compounds. The suggested duration may be set by
default or may be
computed by the processing module 1130 of the expert system 1100 considering
the adjustment
compounds added and/or total volume added (e.g., relative or absolute values).
[0088] The method 4000 may also optionally comprise associating (not
shown) a tolerance
interval with each of the plurality of target values. The plurality of target
values is then
determined 4030 different from the plurality of base values when at least one
base value from
the plurality of base values is outside of the corresponding tolerance
interval. One or more of
the plurality of associated tolerance intervals may be relative values
established in relation to
the starting exterior paint composition, in relation to the adjusted exterior
paint composition and
in relation to the associated target value or the corresponding base value.
One or more of the
plurality of associated tolerance intervals may be an absolute volumetric
value established in
relation to a volume of a container of the starting exterior paint composition
or a remaining
volume estimated or measured (e.g., weighted or measured volume).
[0089] In some embodiments, the starting paint composition may be a
previously adjusted
(or may be roughly adjusted) paint composition. A subsequent adjustment
procedure (or
sequential adjustment procedure) may then further be computed, i.e., similar
to 4002-4050 with
the previously adjusted paint composition as the starting paint composition.
In such an example,
the subsequent adjustment procedure may also indicate one or more adjustment
compounds to
be added. The subsequent adjustment procedure may yet also indicate to dilute
the previously
adjusted paint composition with a plain (i.e., non-adjusted) starting paint
composition and, in
some cases, to afterwards add one or more adjustment compounds following
dilution.
[0090] In some embodiments, the method 4000 may be executed 4050 more
than once for
additional exterior surface(s) to be painted at the paint application site.
The method may
therefore allow to transform the starting exterior paint composition into a
second adjusted
exterior paint composition for a second exterior surface to be painted at the
paint application
site at the geographical coordinates (e.g., a second container of the same
starting composition
or a different starting composition selected based on the substrate
identification of the second
surface). Obtaining the surface characteristics may therefore further comprise
obtaining the
surface characteristics for the second exterior surface to be painted with the
second adjusted
exterior paint composition at the paint application site, the surface
characteristics comprising
the second substrate identification data, a second geographical alignment
value and a second
actual or expected surface temperature for the second exterior surface to be
painted. For instance
the same instrument used to measure the actual temperature of the first
surface may be used for
measuring the temperature of the second surface. The second expected surface
temperature
27
CA 2979100 2017-09-12

value of the surface characteristics may therefore be computed for the second
exterior surface
considering the relative humidity data at the geographical coordinates, the
temperature data for
the geographical coordinates and the second geographical alignment value for
the second
exterior surfaces, and/or wind speed value at the geographical coordinates and
wind orientation
value at the geographical coordinates.
[0091] In some embodiments, the remote device 1200/1300 comprises a
graphical user
interface (not shown) for interacting with one or more users (not shown) and
may also be a
smartphone, a tablet, a phablet, a computer (e.g., portable or fixed to a
mobile unit) or other
multi-purpose processing device. The remote device 1200/1300 may also comprise
an
adjustment compound distribution module (not shown) for receiving the
adjustment procedure
and selectively adding one or more adjustment compounds to the starting
exterior paint
composition in accordance with the adjustment procedure. The adjustment
compound
distribution module may be a module local to the remote device 1200/1300
(e.g., integrated
therewith) or may be a standalone module (not shown) in communication with the
remote device
1200/1300 (e.g., using Bluetooth or other short-range wireless protocol, over
WIFI, over
Ethernet, over USB, etc.). The remote device 1200/1300 may also comprise a
paint mixer tool
and/or paint shaker tool (not shown) for appropriately mixing the adjusted
paint composition
following addition of the adjustment compounds. Duration of the mixing or
shaking operation
may be controlled by the remote device 1200/1300, e.g., in accordance with the
received
adjustment procedure.
[0092] A method is generally conceived to be a self-consistent sequence
of steps leading to
a desired result. These steps require physical manipulations of physical
quantities. Usually,
though not necessarily, these quantities take the form of electrical or
magnetic / electromagnetic
signals capable of being stored, transferred, combined, compared, and
otherwise manipulated.
It is convenient at times, principally for reasons of common usage, to refer
to these signals as
