Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional techniques are used for textile coloring, then manufacturing simplicity is maintained, but dynamic control of structural colors is not achieved

Engineering Contradiction:
Improvedynamic control of structural colorsVSAvoidtextile structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The textile is divided into multiple functional layers including a base fabric layer, structural color layers with different periodic structures, and control elements. Each layer performs a specific function, allowing dynamic control of structural colors while maintaining manufacturing feasibility through modular construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple materials with different optical properties (materials with different refractive indices) to create composite textile structures. These composite structures enable dynamic structural color control by manipulating light interaction through layered configurations of different materials

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If structural color layers are added to control dynamic colors, then design expression is enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improvetextile design expressionVSAvoidtextile manufacturing process
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The control device is designed to perform multiple functions: it can control different structural color layers independently, adjust various color parameters, and adapt to different textile configurations. This multi-functionality reduces the need for separate control systems for each layer, simplifying the overall manufacturing process

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

Solution Approach 2:

The patent utilizes changes in physical parameters (such as periodic structure dimensions, material refractive indices, and layer thicknesses) to achieve dynamic structural color control. By adjusting these parameters rather than adding complex mechanical components, the manufacturing process remains relatively simple while achieving enhanced design expression

Inventive Principle:
Principle #35Parameter changes
