Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional battery top covers have a single function of protecting the battery cell without providing temperature adjustment or enhanced impact strength.
Innovation Solution
A battery top cover with a flow channel area for fluid accommodation to adjust the temperature of the battery cell, combined with a concave-convex structured second heat exchange member for enhanced impact strength and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional battery top cover is used, then the structure is simple and easy to manufacture, but it only provides protection function without temperature adjustment capability
Solution Approach 1:
The battery top cover integrates multiple functions into a single component: it provides mechanical protection through the second heat exchange member, temperature adjustment through the flow channel area with fluid accommodation, and fixation through the first heat exchange member. This multi-functional design resolves the contradiction by making the top cover versatile without proportionally increasing structural complexity.
Solution Approach 2:
The patent merges the protective cover function with the heat exchange function into a single integrated top cover structure. The first heat exchange member, second heat exchange member, and flow channel area are combined to create a unified component that simultaneously protects the battery cell and regulates its temperature.
2Strength
If a traditional battery top cover is used, then the manufacturing process is simple, but the impact strength and protection capability are insufficient
Solution Approach 1:
The top cover is segmented into distinct functional regions: the first heat exchange member for fixation, the second heat exchange member for protection, and the flow channel area for thermal management. This segmentation allows each component to be optimized for its specific function while maintaining manufacturability through modular construction.
Solution Approach 2:
The top cover employs composite structural design combining different material properties in the first and second heat exchange members. The structure integrates materials or designs that provide both high impact strength for protection and appropriate thermal conductivity for heat exchange, while remaining manufacturable.
3Strength
If the second heat exchange member is made with concave-convex structure, then the impact strength is enhanced, but the device complexity increases
Solution Approach 1:
The second heat exchange member features a concave-convex structure with curved surfaces that enhance impact strength by distributing mechanical stresses more effectively than flat surfaces. The convex portions provide structural reinforcement while the concave portions accommodate thermal expansion and fluid flow, improving strength without excessive complexity.
