Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed voltage level capacitor is used, then the device structure is simple, but the adaptability and expansion capability are limited

Engineering Contradiction:

Improveexpansion capabilityVSAvoidmodule structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The capacitor system is divided into multiple independent flexible textile capacitor modules, each with standardized terminals. These modules can be independently manufactured and then combined through the flexible connecting board to achieve different total capacitances and voltage levels, resolving the contradiction between simplicity and adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flexible connecting board is designed with universal compatibility to support multiple connection configurations (series, parallel, series-parallel). This single component enables the same modular structure to serve multiple functions and achieve different electrical specifications without requiring different device designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple capacitors are connected through rigid connecting boards, then the electrical connection is stable, but the flexibility and adaptability of the textile module is reduced

Engineering Contradiction:

ImproveflexibilityVSAvoidelectrical connection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The connecting board is made from flexible textile material rather than rigid PCB material. This flexible connecting board maintains electrical connectivity through conductive traces while accommodating the bending and flexing required for textile applications, thus preserving both flexibility and electrical reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If fixed voltage level capacitors are used, then the manufacturing process is simple, but the applicability to different power consumption devices is limited

Engineering Contradiction:

Improveapplication rangeVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system is segmented into standardized capacitor modules that can be manufactured using consistent processes. The adaptability to different applications is achieved through configuration (series/parallel connections) rather than through customized manufacturing processes, maintaining ease of manufacture while expanding application range.

Inventive Principle:

Principle #1Segmentation
