Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate cooling component (fan) is installed on each battery module, then cooling performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges multiple separate cooling components into a single centralized cooling system. One fan is installed in the container to supply cooling air to multiple battery modules through shared inlet and outlet ducts, eliminating the need for individual fans on each module. This reduces device complexity while maintaining cooling effectiveness across all modules.
Solution Approach 2:
The centralized cooling system serves multiple battery modules simultaneously through a universal cooling infrastructure. The single fan and duct system provides cooling functionality to the entire battery array, making the cooling system multi-functional rather than dedicated to individual modules.
