Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode terminals and bus components are used to achieve electrical connection between battery cells, then reliable electrical connection is achieved, but assembly complexity and time increase significantly
Solution Approach 1:
The patent extracts and removes the electrode terminals and bus components from the battery cell structure, replacing them with a simplified connector system. The connector is directly integrated into the housing, eliminating the need for separate terminal and bus bar assemblies, thus reducing assembly complexity while maintaining electrical connection reliability
Solution Approach 2:
The patent merges the electrical connection function directly into the housing structure by integrating the connector with the housing body. This consolidation eliminates multiple separate components (terminals, bus bars, adapting plates) and simplifies the assembly process into a single plugging operation
2Reliability
If electrode terminals and bus components are used to achieve electrical connection between battery cells, then electrical connection is achieved, but assembly time and manpower requirements increase
Solution Approach 1:
The connector is pre-integrated into the housing structure during manufacturing, so that during assembly, only a simple plugging action is required. The complex electrical connection setup is prepared in advance, eliminating the need for on-site assembly of terminals and bus components
3Reliability
If bus components are provided and connected to electrode terminals, then electrical connection between battery cells is achieved, but internal space utilization decreases
Solution Approach 1:
The connector is merged with the housing structure, eliminating the need for separate bus components and adapting plates. This integration reduces the space required for electrical connections and improves internal space utilization of the battery cell
