Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional water-cooled cooling device with multiple hoses and flow paths is used, then cooling capability is provided, but assembly process becomes complicated and contact area with battery module is reduced
Solution Approach 1:
The patent merges the cooling function directly into the base plate by integrating cooling channels within the base plate structure itself, eliminating the need for separate hoses and auxiliary inlet structures. This consolidation simplifies assembly while maintaining effective cooling capability across multiple battery modules.
Solution Approach 2:
The base plate serves multiple functions simultaneously: it provides structural support for the battery modules, acts as a cooling device with integrated channels, and eliminates the need for separate hose connections. This multi-functionality reduces device complexity while maintaining cooling efficiency.
2Ease of manufacture
If round-shaped flow channels are used in base plate, then cooling device is simple, but contact area with battery module is insufficient for effective cooling
Solution Approach 1:
The patent transitions from simple round cross-sectional channels to rectangular channels that extend in multiple dimensions beneath the battery modules. This dimensional expansion increases the contact area between the cooling channels and battery modules, significantly improving heat transfer efficiency while maintaining manufacturing simplicity.
