Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If partitions with cooling passages are installed between battery cells, then cooling function is provided, but structure becomes complicated and manufacturing becomes difficult
Solution Approach 1:
The cooling function is segmented from the partition structure. Instead of forming passages within partitions, the patent uses separate cooling members (plates with passages) that are coupled to the case, dividing the cooling function into distinct modular components that are easier to manufacture and assemble.
Solution Approach 2:
The cooling passages are extracted from the partition structure and relocated to separate cooling members. This extraction simplifies the partition design while providing the cooling function through dedicated cooling components that can be independently manufactured and assembled.
2Temperature
If partitions with cooling passages are used, then cooling is achieved, but circulation of heat transferring medium is not smooth
Solution Approach 1:
The cooling system is segmented into separate cooling members with dedicated passages, allowing the heat transferring medium to flow smoothly through purpose-designed channels rather than navigating complex partition structures. The segmentation enables optimized passage geometry for smooth circulation.
Solution Approach 2:
Cooling members act as intermediary components between the battery cells and the heat transferring medium. These intermediaries provide dedicated passageways that facilitate smooth circulation of the cooling medium, improving heat transfer efficiency without requiring complex integration into the partition structure.
3Temperature
If complicated structure with passages in partitions is used, then cooling function is provided, but manufacturing becomes difficult
Solution Approach 1:
The manufacturing process is simplified by segmenting the cooling function into separate cooling members that can be manufactured independently using standard fabrication techniques. This avoids the need to manufacture complex integrated partition-passage structures, reducing manufacturing difficulty and cost.
Solution Approach 2:
The cooling passages are extracted from the partition manufacturing process and placed in separate cooling members. This extraction allows each component to be manufactured using simpler, more standard processes, reducing overall manufacturing complexity and difficulty.
