Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional metal shells and cases are used for battery cells, then structural strength and electrical insulation are ensured, but weight increases and energy density decreases
Solution Approach 1:
The patent changes the material parameter from traditional metal to insulating materials (such as plastic or polymer) for both the battery cell shell and the battery case. This material substitution reduces weight while the insulating properties of the new materials inherently provide electrical insulation, eliminating the need for additional insulating layers and maintaining safety requirements.
Solution Approach 2:
The patent merges the structural support function and electrical insulation function into a single insulating material component. The insulating material simultaneously provides mechanical protection and electrical isolation, eliminating the need for separate metal shell and insulating layer, thereby reducing overall weight and simplifying structure.
2Device complexity
If multiple insulating components are used between battery cells and case, then electrical insulation is ensured, but device complexity and weight increase
Solution Approach 1:
The patent combines multiple insulating components into a single integrated insulating structure. The insulating material forms both the battery cell shell and the battery case, creating a unified insulating system that provides complete electrical isolation without requiring multiple separate insulating layers or components.
Solution Approach 2:
The insulating material serves multiple functions simultaneously: it provides electrical insulation, structural support, and mechanical protection. This multi-functional design eliminates the need for specialized insulating components and simplifies the overall battery structure.
