Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling fins are used to accommodate battery cells, then cooling function is provided, but assembly time increases and assembly efficiency decreases
Solution Approach 1:
The housing sheet integrates multiple functions: it serves as both the structural housing and incorporates cooling fin units with thermal interface material. This merging of housing and cooling functions into a single component eliminates the need for separate cooling assemblies, thereby reducing assembly steps and improving assembly efficiency while maintaining effective cooling of battery cells.
2Strength
If multiple housing members are used to accommodate battery cell assembly, then structural support is provided, but module size increases and energy density decreases
Solution Approach 1:
The housing sheet consolidates multiple housing members into a single integrated component that provides comprehensive structural support for the battery cell assembly. By merging the housing function with cooling fins and thermal interface material into one sheet, the overall module size is reduced, volume is optimized, and energy density is improved while maintaining necessary structural strength.
Solution Approach 2:
The housing sheet performs multiple functions simultaneously: it provides structural housing, incorporates cooling fins for thermal management, and includes thermal interface material for heat transfer. This multi-functionality eliminates the need for separate components, reducing module size and increasing energy density while maintaining structural integrity and cooling performance.
3Strength
If conventional housing structure is used, then battery cells are supported, but number of components increases and manufacturing complexity increases
Solution Approach 1:
The housing sheet combines the housing structure, cooling fins, and thermal interface material into a single integrated component. This merging reduces the number of parts from multiple separate housing members and cooling components to one unified sheet, thereby simplifying manufacturing processes, reducing assembly steps, and maintaining adequate support for battery cells.
