Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a textile connector is made flexible to adapt to changing shape, then adaptability is improved, but structural stability and connection reliability deteriorate

Engineering Contradiction:
ImproveflexibilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The textile connector is divided into multiple functional layers: outer textile patches for flexibility and adaptability, inner conductive patches for electrical connection, and thermoplastic patches for structural stability. Each layer performs its specific function while working together to resolve the contradiction between flexibility and connection stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The textile connector uses composite material construction combining textile materials (for flexibility and wear resistance) with conductive materials (for electrical conductivity) and thermoplastic materials (for structural stability). This composite structure allows the connector to simultaneously achieve flexibility and connection reliability.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If traditional manufacturing methods are used, then manufacturing simplicity is maintained, but manufacturing precision and connection reliability deteriorate

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidconnector positioning accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The connector wire is pre-positioned through the thermoplastic patch with a through-hole before lamination. This preliminary positioning action ensures accurate alignment of the conductive path components, achieving high manufacturing precision while maintaining relatively simple manufacturing processes.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the connector wire is exposed for connection, then ease of operation is improved, but protection against wear and tear deteriorates

Engineering Contradiction:
Improvewire accessibilityVSAvoidwear and tear
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The connector wire has different exposure characteristics at different locations: it is exposed through the through-hole at the connection point for ease of operation, while remaining covered and protected by the thermoplastic and textile patches in other areas to protect against wear and tear. This local differentiation resolves the contradiction between accessibility and protection.

Inventive Principle:
Principle #3Local quality
