Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Reliability
If connection devices are designed specifically for a given application, then connection reliability is improved, but adaptability decreases
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.
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.
3Reliability
If spring-loaded conductive pins are used, then electrical conductivity is improved, but device complexity increases
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.
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.
