Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a simple texture film is arranged in the housing, then the manufacturing process is simple, but the visual effect and appearance aesthetics are insufficient

Engineering Contradiction:
Improvemanufacturing process simplicityVSAvoidvisual effect and appearance aesthetics
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The texture layer is divided into multiple structural units (first structural unit, second structural unit, etc.), each containing multiple texture stripes. This segmentation creates a multi-segment curve pattern that mimics hair texture, transforming a simple flat texture into a complex multi-dimensional visual structure that achieves rich appearance effects while maintaining manufacturability through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional flat texture pattern to a three-dimensional multi-segment curve structure by arranging texture stripes at different angles (including -90° to 90° ranges) and creating protruding structures with varying heights. This dimensional transformation enables light to interact with the surface at multiple angles, producing dynamic light and shade changes that enhance visual complexity without significantly complicating the manufacturing process

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a complex multi-layer texture structure is created, then the visual effect and light and shade changing effect are improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvelight and shade changing effectVSAvoidtexture stripe arrangement precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Different first-level regions are designed with different preset angles for texture stripes (ranging from -90° to 90°), creating local variations in light reflection and refraction. This local quality differentiation allows each region to contribute differently to the overall light and shade effect, achieving complex visual outcomes through controlled local variations rather than requiring uniform high-precision manufacturing across the entire surface

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent varies the preset angles of texture stripes across different first-level regions, creating a parameter distribution strategy where angles range from -90° to 90° in different zones. This parameter change approach enables the structure to produce dynamic light and shade effects by controlling the orientation of protruding structures, achieving complex visual effects through parameter variation rather than requiring extremely tight manufacturing tolerances

Inventive Principle:
Principle #35Parameter changes
