Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known feedthrough elements use multiple individual components to provide electrical connection, then electrical conduction is achieved, but device complexity increases and electrical insulation becomes difficult
Solution Approach 1:
The patent combines multiple functions (electrical conduction, insulation, sealing, and mechanical retention) into a single integrated element body. The element body includes a conductive section for electrical connection, an insulating section circumferentially surrounding the conductive section, and a lateral surface that provides sealing and retention, eliminating the need for multiple separate components
Solution Approach 2:
The element body is segmented into functionally distinct sections: a conductive section for electrical conduction, an insulating section for electrical insulation, and a lateral surface for sealing and mechanical retention. This segmentation allows each section to perform its specific function while being part of a unified structure
