Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery modules are mounted in multiple stages, then installation location diversity is improved, but assembly convenience deteriorates
Solution Approach 1:
The battery system is divided into multiple battery modules that can be mounted in different stages (upper and lower cases). Each module is independently coolable with its own cooling block, allowing flexible installation configurations while maintaining assembly simplicity through modular design.
Solution Approach 2:
The cooling apparatus design allows the same cooling block structure to be universally applied to different battery modules regardless of their installation location (upper or lower case). The cooling blocks can be attached to various surfaces including curved surfaces, providing multi-functional cooling capability across diverse installation configurations.
2Productivity
If cooling hose is connected in parallel to multiple cooling blocks, then cooling efficiency is improved, but connection complexity increases
Solution Approach 1:
The cooling hose system employs a dynamic parallel connection configuration where the hose can be flexibly routed to connect multiple cooling blocks simultaneously. This parallel arrangement allows the cooling medium to flow through multiple cooling blocks at the same time, improving overall cooling efficiency while the flexible hose design accommodates the increased number of connections without requiring complex rigid piping.
3Area of stationary object
If battery system is installed away from bottom of vehicle, then space utilization is improved, but vibration stability deteriorates
Solution Approach 1:
The cooling blocks are designed with different lengths in the longitudinal direction to match the specific installation location and battery module configuration. The lowermost cooling block has the largest length, while upper cooling blocks have progressively smaller lengths. This localized adaptation ensures optimal cooling coverage and vibration damping at each installation position, whether in the upper or lower case.
