Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If discrete encoded values are used to represent colors in digital devices, then storage and communication efficiency is improved, but color accuracy and precision deteriorate due to approximations in the continuous color space

Engineering Contradiction:
Improvedata storage efficiencyVSAvoidcolor accuracy
Core Design Contradiction:
Loss of substanceVSMeasurement precision

Solution Approach 1:

The color space is segmented into a hierarchical structure with a root node representing the full color space and child nodes representing progressively finer color subdivisions. This segmentation allows selective precision - using fewer segments (coarser granularity) for colors that don't require high accuracy, and more segments (finer granularity) for colors that do, thereby optimizing the trade-off between data storage efficiency and color accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the granularity of color representation based on the specific color being encoded. Rather than using a fixed discrete encoding scheme, the system can adaptively allocate more precision to certain color regions where human perception is more sensitive, while using coarser encoding in less critical regions, thus improving overall color accuracy without proportionally increasing data storage requirements.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If higher precision color encoding is used, then color accuracy is improved, but data storage requirements and communication overhead increase

Engineering Contradiction:
Improvecolor accuracyVSAvoiddata storage requirements
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The color encoding system uses a nested hierarchical structure where child nodes are contained within parent nodes. Each level of the hierarchy represents a different granularity of color precision. This nesting allows the system to store color information at multiple levels of detail, enabling efficient compression by storing only the necessary precision for each color rather than always using maximum precision, thereby reducing overall data storage requirements while maintaining color accuracy where needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If standardized color systems like CMYK or Pantone are used, then ease of operation and device compatibility are improved, but manufacturing precision and color reproduction accuracy deteriorate due to system limitations

Engineering Contradiction:
Improvedevice compatibilityVSAvoidcolor reproduction accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The fractal-based color encoding system is designed to be universal and compatible with multiple existing color systems including CMYK, Pantone, and device-specific color spaces. The system can translate between these different color models while maintaining the benefits of fractal encoding, thereby providing both ease of operation across different devices and high manufacturing precision through its ability to represent colors with arbitrary precision independent of device-specific limitations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
