Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mass-produced paint color swatches do not effectively assess the hiding power of paints, leading to unexpected color outcomes on painting projects due to the poor hiding power of high chroma paints, and users are unaware of how to improve this with neutral white or gray primers.
Innovation Solution
A paint swatch test device with a transparent substrate and multiple primer coating patches of varying white and gray shades, allowing users to visually evaluate the color and hiding power of topcoat paints, including the effect of neutral primers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mass-produced paint color swatches are used to evaluate paint color, then color selection is simplified and inventory is managed economically, but hiding power assessment is completely lost
Solution Approach 1:
The test device segments the evaluation process by separating color assessment from hiding power assessment. It uses multiple substrate types (opaque white, opaque gray, translucent) to independently evaluate different paint properties, allowing users to assess both color and hiding power without requiring multiple separate swatch sets.
Solution Approach 2:
The test device combines multiple evaluation functions into a single swatch set. By incorporating various substrate types that represent different real-world painting scenarios, the device universally evaluates both color appearance and hiding power across different surface conditions, replacing the need for separate color swatches and hiding power tests.
2Quantity of substance
If high chroma paints are used to achieve vivid colors, then color saturation is improved, but hiding power deteriorates causing substrate color show-through
Solution Approach 1:
The test device applies local quality by using different substrate types in specific regions to represent different real-world conditions. Opaque substrates simulate surfaces requiring high hiding power, while translucent substrates simulate surfaces where some show-through is acceptable, allowing users to evaluate how high chroma paints perform in each specific context.
Solution Approach 2:
The device evaluates color changes by comparing the appearance of high chroma paint on different substrate backgrounds. Users can observe how the paint color shifts when applied over white versus gray substrates, and how much substrate color shows through, providing comprehensive feedback on both color saturation and hiding power performance.
3Reliability
If neutral white or gray primers are applied to improve hiding power, then substrate show-through is reduced, but the complexity of the painting process increases
Solution Approach 1:
The test device performs preliminary action by pre-applying neutral white and gray primer coatings to specific substrate areas before the user applies the test paint. This allows users to evaluate the effect of priming on hiding power and color appearance without having to separately apply primers in the field, simplifying the overall process while maintaining evaluation accuracy.
Solution Approach 2:
The primer coatings serve as intermediaries between the substrate and the topcoat paint. By incorporating these intermediary layers into the test device, users can evaluate how different primer types affect the final color appearance and hiding power, providing guidance on whether priming is necessary for their specific painting project.
4Reliability
If multiple coats of paint are applied to achieve adequate hiding power, then substrate show-through is eliminated, but material cost and time consumption increase
Solution Approach 1:
The test device applies partial action by using substrates with varying degrees of opacity (from opaque white to translucent) to simulate the effect of applying different numbers of paint coats. A single coat of paint evaluated on a translucent substrate simulates the appearance after one coat, while the same paint on an opaque substrate simulates the appearance after sufficient coats, allowing users to predict the number of coats needed without actually applying multiple coats.

AI summary
A paint swatch test device includes a transparent or translucent substrate, such as a sheet of polymeric material, and a plurality of different primer coating patches on the substrate. The patches preferably form a grayscale series of neutral white and gray primer patches having stepwise increments in light reflectance values. The patches can also be provided on an opaque substrate. The color suitability and/or hiding power of a topcoat paint desired to be applied to a surface to be painted can be determined by coating the topcoat paint on at least a portion of a surface of the transparent or translucent substrate, providing a grayscale series of patches between the paint coating and the surface to be painted, and observing the appearance of the paint coating where patches are beneath the coating and where patches are not beneath the coating.
