Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection structure with multiple connection units is used, then reliable electrical connection between cells is achieved, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent combines multiple separate connection units into a single integrated connector that simultaneously connects multiple cells. The integrated connector includes multiple connection terminals that can electrically connect multiple cells in series or parallel configurations within a single component, eliminating the need for multiple separate connection units and their associated fasteners.
Solution Approach 2:
The integrated connector is designed to perform multiple functions: it provides electrical connection between cells, structural support for the cells, and integration for both series and parallel connection configurations. This multi-functional design reduces the overall number of components needed in the battery assembly.
2Reliability
If conventional connection structure with multiple connection units is used, then electrical connection between cells is achieved, but production cost increases due to increased number of parts
Solution Approach 1:
By merging multiple connection units into a single integrated connector, the patent reduces the total number of parts that need to be manufactured, inventoried, and assembled. This consolidation directly reduces production costs while maintaining the necessary electrical connection reliability through the integrated design.
3Reliability
If conventional connection structure with multiple connection units is used, then cells can be connected in series, but the volume of connection structure increases
Solution Approach 1:
The integrated connector consolidates multiple connection functions into a single compact component that occupies less space than multiple separate connection units. The design allows for efficient spatial arrangement of connection terminals to achieve series connections while minimizing the overall volume of the connection structure.
4Reliability
If conventional connection structure with multiple connection units is used, then electrical connection is achieved, but assembly process becomes complicated
Solution Approach 1:
The integrated connector reduces the number of assembly steps by consolidating multiple connection operations into a single assembly action. Instead of installing multiple separate connection units, the integrated connector can be installed as one component, significantly simplifying the assembly process and improving production efficiency.
