Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional beams and structures are added to ensure electrical insulation and heat conduction, then safety performance is improved, but space utilization rate decreases and energy density is reduced
Solution Approach 1:
The heat conducting member is designed to perform multiple functions simultaneously: it conducts heat away from battery cells, provides electrical insulation through its material composition, and serves as a structural support element within the battery pack. This multi-functionality eliminates the need for separate beams and insulation structures, maximizing space utilization while maintaining safety performance
Solution Approach 2:
The patent combines the functions of heat conduction and electrical insulation into a single integrated component - the heat conducting member. By merging these previously separate functions into one element, the design achieves both thermal management and electrical isolation without occupying additional space that would be required for separate structures
2Temperature
If heat conducting member dimension is increased to improve heat conduction, then thermal management is improved, but space for battery cells is reduced
Solution Approach 1:
The patent optimizes the dimension of the heat conducting member within a specific range (0.1-100 mm) to achieve the best balance between heat conduction efficiency and space utilization. By carefully selecting and adjusting this dimensional parameter, the design ensures adequate thermal management while maximizing the space available for battery cells
