Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cooling structures and reinforcement structures are provided separately, then thermal management and structural strength requirements are met, but space utilization is reduced and weight increases
Solution Approach 1:
The patent combines the cooling structure and reinforcement structure into a single integrated component. The heat exchange plate is designed with rib structures that simultaneously provide thermal management functionality and structural reinforcement, eliminating the need for separate cooling plates and reinforcement beams, thereby reducing weight while maintaining both thermal management and structural strength requirements
Solution Approach 2:
The heat exchange plate is designed to serve multiple functions: it acts as a cooling component for thermal management, provides structural reinforcement through integrated rib structures, and serves as a mounting platform for battery modules. This multi-functional design eliminates the need for separate components, reducing overall battery weight while meeting all structural and thermal requirements
