Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If space utilization ratio is improved by direct connection, then energy density is improved, but structural strength may be compromised
Solution Approach 1:
The patent applies parameter changes by establishing a specific thickness range for the mounting wall (H/M ratio between 0.04mm/kg and 100mm/kg) to simultaneously achieve both space utilization and structural strength requirements. This quantitative parameter optimization resolves the contradiction between compact design and mechanical strength.
Solution Approach 2:
The mounting wall is designed as a composite structure that integrates both mechanical support function and space optimization. By using composite material principles, the mounting wall achieves sufficient strength while maintaining minimal thickness to maximize battery cell arrangement density.
2Strength
If mounting wall thickness is increased to improve structural strength, then space utilization ratio decreases, leading to reduced energy density
Solution Approach 1:
The patent resolves this contradiction by defining an optimal parameter range for mounting wall thickness relative to battery cell weight (H/M ratio). This parameter optimization ensures the mounting wall is thick enough for structural strength but thin enough to minimize space consumption, thereby maintaining high energy density.
3Strength
If gaps are left between battery cell and mounting wall, then structural strength is maintained, but space utilization ratio decreases
Solution Approach 1:
The patent eliminates gaps by optimizing the mounting wall thickness parameter to achieve direct contact between the battery cell first wall and mounting wall. This parameter optimization maintains structural strength through proper material selection and thickness control while maximizing space utilization.
