Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If five primary colors (magenta, yellow, cyan, black, white) are used to construct the HSB color space, then the color space can be built with basic mixing, but the color yield is low and chromatography is narrow

Engineering Contradiction:

Improvecolor space constructionVSAvoidcolor yield

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The invention divides the color space construction into multiple stages: first establishing a basic five-primary-color framework, then segmenting and adding specialized color regions (red, green, blue, cyan, magenta, yellow) to expand the gamut. This segmentation allows systematic expansion from a simple to a comprehensive color space

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a composite color space model that integrates five basic primary colors with eight expanded primary colors. This composite approach combines the simplicity of the original five-color system with the expanded gamut of the eight-color system, achieving both ease of construction and high color yield

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If five primary colors are used for color mixing, then the mixing process is simple, but the chromatography coverage is narrow

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention extends the color space from a basic 5-color model to an 8-color model by adding three-dimensional color depth. This dimensional expansion allows the system to cover broader chromatography ranges while maintaining the operational simplicity of systematic color mixing procedures

Solution Approach 1:

The invention implements a dynamic color space meshing system that adapts to different color gamut requirements. The mesh structure can dynamically adjust its density and distribution based on the specific color matching task, enabling both high precision in critical regions and comprehensive coverage across the full color gamut

AI summary

A method for constructing a meshed model and a discrete chromatography of eight primary color HSB color space is provided. By a meshed digital model and a discrete algorithm of color space, the color value and the color distribution in any point, line, surface and space area in the HSB color space can be quickly obtained based on color values of eight primary colors and coordinate values of mesh points in the HSB color space, thereby (i) realizing the full color gamut discrete chromatography of the HSB color space, (ii) realizing the visualization of the full color gamut of the color space, and (iii) improving the work efficiency of color matching.
