Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing color cards designed for low color display standards are used, then the color card generation process is simple, but the visual effects are abnormal when applied to high color display standards

Engineering Contradiction:

Improvevisual effect accuracyVSAvoidcolor card generation process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent transforms color data from one color space to another by changing the parameter representation. Specifically, it converts standard colors from the first color display standard's color space to the second color display standard's color space using color space transformation algorithms, ensuring accurate visual effects on high color display standards while maintaining a systematic generation process

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary color space transformation process between the original color card data and the final output. By using color space conversion as an intermediary step, it bridges the gap between different color display standards, allowing color cards designed for one standard to be accurately adapted to another standard with different color gamuts

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If color space transformation and channel separation are performed, then the color gamut matching is improved, but the processing complexity increases

Engineering Contradiction:

Improvecolor gamut matchingVSAvoidprocessing steps

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies channel separation to divide the color data into individual color channels (e.g., R, G, B channels). By segmenting the color information, it enables precise adjustment of each channel's characteristics to match the target color display standard's color gamut, achieving accurate color reproduction through targeted channel-specific processing

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adjusts color components locally in each color channel rather than applying uniform processing to all color data. By performing channel separation and adjusting color components independently for each channel, it achieves precise local optimization of color characteristics to match the target color gamut, improving color accuracy without unnecessarily complicating the overall process

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If standard colors are transferred to a larger color range standard, then the color richness is improved, but the data transformation complexity increases

Engineering Contradiction:

Improvecolor display compatibilityVSAvoiddata transformation process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal color card generation method that can adapt to multiple different color display standards. By establishing a standardized transformation pipeline that works across different color spaces and standards, it enables a single color card generation system to produce compatible color cards for various display technologies, from standard dynamic range to high dynamic range displays

Inventive Principle:

Principle #6Universality (Multi-functionality)
