Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high energy storage density is achieved by increasing battery cell arrangement compactness, then energy density improves, but temperature control effectiveness deteriorates due to limited heat dissipation space
Solution Approach 1:
The temperature control element extends in multiple directions (first direction for heat transfer surface, second direction for holding projection) to provide both thermal management and mechanical support functions, effectively utilizing spatial dimensions to resolve the conflict between compact energy storage and effective temperature control
Solution Approach 2:
The temperature control element serves dual functions: it acts as a heat transfer component for temperature control and simultaneously provides mechanical support through the holding projection for guiding and positioning battery cells, thereby achieving multi-functionality in a compact design
2Device complexity
If traditional temperature control elements are used without holding projections, then device complexity remains low, but mechanical guidance and positioning of battery cells deteriorates
Solution Approach 1:
The temperature control element is designed to perform multiple functions simultaneously: heat transfer for temperature control and mechanical support through holding projections for guiding and positioning battery cells, eliminating the need for separate components
Solution Approach 2:
The holding projection is integrated directly into the temperature control element, merging the thermal management function and mechanical support function into a single unified component, thereby simplifying the overall structure while improving functionality
