Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple circuit boards and components are integrated into a compact housing, then functionality and portability are improved, but connection reliability and assembly complexity worsen
Solution Approach 1:
The conductive pin is inserted through a through-hole in the housing, with its first portion inside the housing and second portion extending outward. The flexible circuit board is positioned between the conductive pin and the second circuit board, creating a nested arrangement where multiple components are integrated within the compact housing space, enabling efficient use of limited volume while maintaining multiple functions
Solution Approach 2:
The flexible circuit board acts as an intermediary component between the conductive pin and the second circuit board. It provides electrical connection and mechanical flexibility, mediating the connection between rigid components and allowing for assembly tolerance while maintaining connection reliability in the compact structure
2Adaptability or versatility
If conductive pin extends through housing to enable external connection, then connectivity is improved, but structural integrity and protection worsen
Solution Approach 1:
The conductive pin is nested within the housing structure, with its first portion disposed in a through-hole formed on the housing. This nested arrangement allows the pin to extend outward for external connectivity while being protected by the housing, reducing structural vulnerability while maintaining connectivity functionality
Solution Approach 2:
The conductive pin is pre-positioned within the housing before final assembly, with its first portion already disposed in the through-hole. This preliminary positioning ensures proper alignment and protection before the flexible circuit board and other components are assembled, preventing misalignment damage and ensuring structural integrity
