Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If card edge connectors with exposed printed circuit board are used, then high density electrical connections can be achieved, but reliability and safety deteriorate due to exposed conductive contacts

Engineering Contradiction:
Improvenumber of electrical connectionsVSAvoidsafety and reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent employs a disposable connector housing that integrates the printed circuit board within an enclosed structure. This disposable approach allows for high-density connections while eliminating the need for exposed conductors, as the entire connector can be replaced rather than maintained, ensuring safety without compromising connection density

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The connector design integrates multiple functions into a single enclosed housing: the printed circuit board provides electrical connections, the housing provides structural support and environmental protection, and the integrated design eliminates the need for separate exposed conductor elements. This multi-functionality achieves high-density connections while maintaining safety through enclosure

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

2Quantity of substance

If card edge connectors are designed for specific circuit boards, then electrical connection can be achieved, but manufacturing cost increases due to lack of scalability

Engineering Contradiction:
Improveelectrical connection capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The connector housing is designed as a universal platform that can accommodate different printed circuit board configurations. The standardized enclosed housing structure allows the same basic design to serve multiple applications, enabling economies of scale in manufacturing while maintaining the ability to provide high-density electrical connections for various systems

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

3Quantity of substance

If exposed conductive surfaces are used for electrical connection, then electrical coupling is achieved, but contamination and degradation increase over time

Engineering Contradiction:
Improveelectrical conductivityVSAvoidcontamination and degradation
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes an enclosed housing structure that acts as a protective shell around the printed circuit board and conductive elements. This enclosure prevents direct exposure to environmental contaminants while maintaining electrical functionality through sealed interfaces, thereby eliminating contamination and degradation issues associated with exposed conductors

Inventive Principle:
Principle #30Flexible shells and thin films
