Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid connection members are used to connect single cells, then connection strength is improved, but mounting failure occurs due to dimensional errors between cells and wiring module
Solution Approach 1:
The connection member is designed with a flexible portion that can elastically deform, transforming the rigid connection into a dynamic one. This allows the connection member to adapt to dimensional variations between single cells through elastic deformation, preventing mounting failure while maintaining connection strength.
Solution Approach 2:
The connection member's physical state is changed by introducing a flexible portion with different rigidity characteristics. This parameter change allows the connection member to accommodate dimensional errors by deforming within elastic limits, resolving the contradiction between maintaining strength and avoiding mounting failure.
2Manufacturing precision
If precise dimensional control is implemented between cells and wiring module, then mounting accuracy is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The invention extracts the dimensional error compensation function from the manufacturing process and transfers it to the connection member's elastic deformation capability. This eliminates the need for precise dimensional control during manufacturing, reducing complexity while maintaining mounting accuracy.
Solution Approach 2:
The flexible portion of the connection member serves as a pre-designed compensation mechanism that absorbs dimensional errors before they cause mounting failure. This beforehand cushioning approach eliminates the need for post-manufacturing adjustments or extremely tight tolerances.
3Reliability
If multiple adjustment mechanisms are added to accommodate dimensional errors, then mounting reliability is improved, but device complexity increases
Solution Approach 1:
The invention merges the dimensional error compensation function directly into the connection member's structure through the flexible portion. This integration eliminates the need for separate adjustment mechanisms, maintaining mounting reliability while avoiding increased device complexity.
Solution Approach 2:
The connection member's flexible portion automatically compensates for dimensional errors through elastic deformation without requiring external adjustment mechanisms. This self-service approach improves mounting reliability while keeping the structure simple.

AI summary
A cell wiring module is configured to include a plurality of connection members connecting adjacent electrode terminals of a plurality of single cells having positive and negative electrode terminals. The cell wiring module includes a first unit housing a housed connection member, and a second unit connected to the first unit by a linking connection member different from the housed connection member. Sliding occurs in the connection direction of the connection members between the linking connection member for connection and at least one of the first unit and the second unit.
