Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If metal radiation plates are used to improve heat conductivity, then heat radiation efficiency is improved, but weight increases and electric short-circuit risk increases
Solution Approach 1:
The holding unit applies different material properties to different regions: insulating material on the ends where electrical isolation is critical, and heat-conductive material in the middle section where heat radiation is prioritized. This local differentiation resolves the contradiction by allowing heat radiation efficiency improvement without compromising weight or safety.
Solution Approach 2:
The holding unit is divided into multiple holding units (first, second, and third holding units) with different material compositions. The first and second holding units use insulating material, while the third holding unit uses heat-conductive material. This segmentation allows simultaneous achievement of weight reduction and heat radiation efficiency improvement.
2Temperature
If metal radiation plates are used to improve heat conductivity, then heat radiation efficiency is improved, but safety decreases due to electric short-circuit risk
Solution Approach 1:
Insulating material is strategically placed at the end portions of the holding unit where electrical isolation from cell terminals is most critical, while heat-conductive material is used in the middle section for optimal heat radiation. This local quality differentiation ensures safety is maintained where needed while heat radiation efficiency is improved where appropriate.
Solution Approach 2:
The insulating material acts as an intermediary between the heat-conductive material and the cell terminals, preventing direct electrical contact while allowing thermal management. This intermediary approach resolves the safety concern by isolating conductive materials from electrical components.
3Reliability
If insulating material is used for the entire holding unit, then safety is improved, but heat radiation efficiency decreases
Solution Approach 1:
The holding unit transitions from uniform insulating material to a composite structure with different material properties in different regions. The third holding unit specifically uses heat-conductive material to improve heat radiation efficiency in the middle section, while end portions maintain insulating material for safety.
Solution Approach 2:
The holding unit is segmented into first, second, and third holding units with different material compositions. This segmentation allows the system to achieve both safety (through insulating material at critical locations) and heat radiation efficiency (through heat-conductive material in the middle section).
