Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connection devices are designed and manufactured specifically for a given application, then connection quality is improved, but cost increases and replaceability decreases

Engineering Contradiction:
Improveconnection qualityVSAvoidcost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection device is divided into two separate components: a reusable connection cord with spring-loaded conductive pins and a disposable interconnection module with connection pads. This segmentation allows the expensive, precision-engineered cord to be reused while only the cheaper module is application-specific, reducing overall cost while maintaining connection quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring-loaded conductive pins are extracted from the application-specific connector and placed in a separate, reusable connection cord. This extraction allows the pins to be used across multiple applications through different interconnection modules, reducing manufacturing costs while preserving the high-quality electrical connection capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If connection devices are designed specifically for a given application, then connection reliability is improved, but adaptability decreases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidreplaceability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connection cord with spring-loaded pins is designed as a universal component that can interface with multiple types of interconnection modules through standardized mechanical and electrical interfaces. This universality allows a single cord to serve multiple applications, improving adaptability while maintaining reliable connections through the consistent spring-loaded pin design.

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

Solution Approach 2:

The interconnection module acts as an intermediary between the reusable connection cord and the application-specific circuit board. It provides the necessary adaptation while allowing the high-quality cord to remain unchanged, enabling replaceability without sacrificing connection reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If spring-loaded conductive pins are used, then electrical conductivity is improved, but device complexity increases

Engineering Contradiction:
Improveelectrical conductivityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The complex spring-loaded conductive pin mechanism is extracted and isolated in a dedicated reusable connection cord, separate from the simpler interconnection module. This extraction concentrates the complexity in one component that can be reused, while the application-specific module remains simple and inexpensive to manufacture.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spring-loaded pins provide self-aligning and self-contacting capabilities through their inherent mechanical design. The spring force automatically ensures electrical contact without requiring complex alignment mechanisms or additional adjustment components, maintaining simplicity while ensuring reliable electrical conductivity.

Inventive Principle:
Principle #25Self-service
