Engineering Contradiction Analysis
1Power
If multiple battery cells are electrically connected to form a battery module, then output and capacity are enhanced, but space utilization of the battery pack deteriorates
Solution Approach 1:
The side plate, cell terminal, and busbar holder are integrated into a single symmetrically arranged structure that combines multiple functional components. This merging reduces the number of separate parts and optimizes space utilization while maintaining enhanced output and capacity from multiple battery cells.
Solution Approach 2:
The side plate serves multiple functions: it provides structural support, houses the cell terminal, accommodates the busbar holder, and enables symmetric arrangement of components. This multi-functionality allows the battery module to achieve high power output while maintaining compact space utilization.
2Volume of moving object
If symmetric arrangement of side plates, cell terminals, and busbar holders is implemented, then space utilization is improved, but device complexity increases
Solution Approach 1:
While the overall arrangement is symmetric, the individual components (side plate with protruding portion, busbar holder with opening) have asymmetric features that simplify manufacturing and assembly. The asymmetric design of individual parts enables the symmetric configuration to achieve optimal space utilization without excessive complexity.
