Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If card edge connectors are used to achieve high-density electrical connections, then the number of signals that can be connected increases, but safety risks increase due to exposed conductive surfaces

Engineering Contradiction:
Improvenumber of signalsVSAvoidsafety risks from exposed conductors
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent embeds the conductive contacts within an enclosed connector housing that integrates the printed circuit board. The contacts are nested inside the housing structure rather than exposed on the board edge, allowing high-density connections while preventing direct exposure to the environment. This nesting approach resolves the contradiction by maintaining signal density while eliminating safety hazards from exposed conductors.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent uses a standardized printed circuit board design that can be easily manufactured and replaced. The enclosed connector housing protects the conductive elements, allowing for cost-effective manufacturing while maintaining safety. This approach enables high-density connections without the specialized, expensive custom designs required by traditional card edge connectors.

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

2Quantity of substance

If card edge connectors with exposed printed circuit boards are used, then high-density connections are achieved, but manufacturing cost increases due to specialized designs

Engineering Contradiction:
Improvenumber of signalsVSAvoidmanufacturing cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent employs a universal printed circuit board design with standardized contact arrangements that can be used across multiple applications. The enclosed connector housing provides a generic platform that accommodates various signal densities without requiring custom board designs. This universality reduces manufacturing costs while maintaining the capability for high-density electrical connections.

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

Solution Approach 2:

The patent combines the printed circuit board, contact elements, and protective housing into an integrated connector assembly. This merging of components eliminates the need for separate specialized board designs and reduces manufacturing complexity. The integrated design achieves high-density connections at lower cost by consolidating functions into a single manufacturable unit.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If exposed printed circuit boards are used in card edge connectors, then electrical connections are established, but reliability decreases due to contamination and degradation

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidcontamination and degradation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses an enclosed housing structure that acts as a protective shell around the conductive contacts and printed circuit board. This enclosure prevents contaminants, moisture, and other environmental factors from reaching the electrical contacts. The housing maintains reliable electrical connections by isolating the conductive elements from degrading environmental conditions throughout the product lifecycle.

Inventive Principle:
Principle #30Flexible shells and thin films

4Reliability

If card edge connectors are designed for specific circuit boards, then connections are optimized, but adaptability decreases across different systems

Engineering Contradiction:
Improveconnection optimizationVSAvoidsystem compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs the connector with a standardized enclosed housing and contact arrangement that can interface with various printed circuit board configurations. The universal design allows the same connector type to be adapted to different systems and signal densities without requiring custom specialized designs, thereby improving both adaptability and maintaining connection reliability through standardized interfaces.

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