Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If space utilization ratio is increased to improve energy density, then structural strength may be compromised
Solution Approach 1:
The mounting wall is integrated directly with the battery cell structure, merging the mounting function into the cell design. This eliminates separate mounting components and gaps, achieving both high space utilization and structural strength through a unified structure.
Solution Approach 2:
The mounting wall serves multiple functions: it provides structural support, enables direct mounting of battery cells, and maintains structural strength while optimizing space. This multi-functionality resolves the contradiction by making a single component fulfill both space efficiency and strength requirements.
2Strength
If mounting wall size H is increased to improve structural strength, then space utilization ratio decreases
Solution Approach 1:
The patent specifies an optimal parameter range for the mounting wall size H (0.04 mm/kg ≤ H/M ≤ 100 mm/kg). By controlling this parameter within the specified range, the design achieves both adequate structural strength and high space utilization ratio, resolving the contradiction through precise parameter optimization.
3Reliability
If gaps are left between battery cell and mounting wall for safety, then space utilization ratio and energy density decrease
Solution Approach 1:
The mounting wall is designed to be in direct contact with the battery cell without gaps, merging the cell and mounting structures. This eliminates wasted space while maintaining safety through the integrated design that provides both mounting function and structural protection.
Solution Approach 2:
The mounting wall structure itself provides the safety function through its integrated design with the battery cell. The structure serves its own safety and mounting needs simultaneously, eliminating the need for separate safety gaps or components.
