Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If contacts are retained in housing without additional support structures, then device complexity is reduced, but contact deformation occurs under compression
Solution Approach 1:
The locating pole acts as an intermediary support structure between the housing and the contact. It provides additional mechanical support to the resilient portion of the contact without requiring major changes to the housing design, thereby preventing contact deformation under compression while maintaining relatively simple device complexity.
2Ease of operation
If contacts are made more resilient to ensure electrical connection, then ease of operation is improved, but contact deformation under compression worsens
Solution Approach 1:
The locating pole provides localized support specifically to the resilient portion of the contact that is prone to deformation. This allows the contact to maintain its resilience for making electrical connections while the locating pole prevents excessive deformation under compression, effectively addressing different functional requirements in different regions of the contact structure.
3Ease of operation
If contact passages are enlarged to accommodate contact movement, then ease of operation is improved, but contact stability deteriorates
Solution Approach 1:
The locating pole serves as a mediator that allows the contact to move within the contact passage for engagement purposes while simultaneously providing positional stability. The pole is positioned to permit necessary movement but prevents excessive displacement, thereby maintaining contact position stability without restricting operational capability.
