Engineering Contradiction Analysis
1Reliability
If additional fastening components are used to connect sensing members to bus bars, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The bus bar is designed with an integrated insertion part (groove or through hole) that combines the functions of electrical connection and mechanical fastening into a single component, eliminating the need for separate fastening components and reducing device complexity while maintaining connection reliability
Solution Approach 2:
The bus bar structure itself provides the fastening function through its built-in insertion part, allowing the sensing member to be securely connected without requiring external fastening components, thereby simplifying the overall device structure
2Reliability
If additional fastening components are used to connect sensing members to bus bars, then connection reliability is improved, but manufacturing cost increases
Solution Approach 1:
The insertion part is integrated into the bus bar as a single component, eliminating the need for separate fastening parts and reducing the total number of components that need to be manufactured and assembled, thereby lowering manufacturing cost while maintaining connection reliability
Solution Approach 2:
The bus bar structure itself provides the fastening function through its built-in insertion part, allowing the sensing member to be securely connected without requiring external fastening components, thereby simplifying the overall device structure
3Reliability
