Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery case is designed with a fixed cooling structure, then manufacturing costs increase when accommodating battery modules with different cooling requirements, but using a variable cooling structure would require replacing cooling components
Solution Approach 1:
The cooling flow passage is designed with asymmetric cross-sectional areas at different positions, creating local variations in cooling capacity. The first cross-sectional area (first cooling region) and second cross-sectional area (second cooling region) are deliberately made different to provide localized cooling optimization for battery modules with varying heat generation characteristics, eliminating the need to replace entire cooling components
Solution Approach 2:
The cooling flow passage employs an asymmetric geometry where the cross-sectional area varies along the flow direction. This asymmetric design allows the cooling panel to accommodate battery modules with different characteristics by orienting the panel differently, providing adaptability without requiring component replacement while maintaining a simple fixed structure
2Adaptability or versatility
If cooling flow passage has uniform cross-sectional area, then manufacturing is simpler, but cooling performance cannot be optimized for different battery characteristics
Solution Approach 1:
The cross-sectional area parameter of the cooling flow passage is deliberately varied along the flow direction, creating regions with different cooling capacities. This parameter change enables the single cooling panel to be optimized for different battery characteristics by changing its installation orientation, achieving adaptability while maintaining manufacturability through a fixed molded structure
