Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interface portion is made configurable for different applications, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The connector is divided into a cable portion and an interface portion that can be separately configured and assembled. The interface portion can be adapted for different applications by selecting different geometric configurations, while the cable portion remains standardized. This segmentation allows adaptability without proportionally increasing overall complexity.
Solution Approach 2:
The connector design allows a single basic structure to serve multiple functions by configuring the interface portion for different applications. The same fundamental connector type can be adapted to various interface geometries, making it universally applicable across different scenarios without requiring entirely different connector designs.
2Adaptability or versatility
If the connector is constructed from multiple pieces for variable configuration, then the adaptability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The interface portion is pre-configured with specific geometric adaptations during manufacturing, allowing for easy final assembly. By preparing the interface portion in advance with the required configuration, the actual assembly process becomes simpler and more efficient, despite the multi-piece construction.
3Ease of manufacture
If the inner interface contact is directly attached to the cable insulator, then the manufacturing simplicity is improved, but the reliability of electrical connection may deteriorate
Solution Approach 1:
The cable insulator serves as an intermediary element that provides both mechanical support and electrical insulation between the inner interface contact and the outer conductor. This intermediary role ensures reliable electrical connection while maintaining proper insulation, resolving the potential conflict between manufacturing simplicity and connection reliability.
