Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling systems are used for large electrical storage devices, then the device volume can be accommodated, but the thermal regulation efficiency is insufficient and the system becomes complex
Solution Approach 1:
The patent combines the support structure and thermal regulation function into a single integrated rigid support part. The support part contains both receiving cavities for battery cells and channels for thermal regulation fluid, merging structural support and thermal management into one component, thereby simplifying the overall system while improving thermal regulation efficiency
Solution Approach 2:
The rigid support part serves multiple functions simultaneously: it provides mechanical support for the battery cells, acts as a thermal regulation medium through its high thermal conductivity material, and contains integrated channels for fluid circulation. This multi-functionality reduces the need for separate cooling system components
2Temperature
If thermal regulation means are placed close to electrical elements, then heat transfer efficiency improves, but thermal homogeneity across the element deteriorates
Solution Approach 1:
The rigid support part is segmented into multiple receiving cavities and channels arranged in a specific pattern. The channels are distributed to contact different regions of the battery cells, ensuring that heat is extracted from multiple points simultaneously, which maintains high heat transfer efficiency while achieving uniform thermal distribution across the entire cell
Solution Approach 2:
The patent applies different thermal regulation characteristics to different regions by strategically positioning channels at specific locations around the receiving cavities. The rigid support part's high thermal conductivity material locally transfers heat from the battery cell surfaces to the channels, creating optimal thermal contact zones while maintaining overall thermal homogeneity
