Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pouch battery modules with frame structures are heavy and costly due to the use of plastic frames and heat sink plates, leading to increased weight and expense when multiple battery packs are required.
Innovation Solution
A pouch battery module design featuring a metal housing with pouch battery cells arranged along a direction and secured by rigid insulation plates, eliminating the need for a frame structure, reducing component count, and enhancing energy density and cost efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a frame structure with plastic frame and heat sink plate is used, then structural support and thermal management are provided, but weight and cost increase
Solution Approach 1:
The patent removes the plastic frame structure from the battery module design. Instead of using a separate frame to hold battery cells, the cells are directly arranged and fixed within the housing, eliminating the need for the frame and reducing overall weight while maintaining structural integrity through direct cell-to-housing arrangement
Solution Approach 2:
The patent integrates the heat sink function directly into the battery cell structure by embedding heat dissipation plates within the cell housing or structure. This merging of thermal management functionality into the existing structure eliminates separate heat sink components and reduces overall module weight
2Strength
If a frame structure with plastic frame and heat sink plate is used, then structural support and thermal management are provided, but cost increases
Solution Approach 1:
By removing the plastic frame structure entirely, the patent reduces the number of components that need to be manufactured, assembled, and quality-checked. This simplification directly reduces manufacturing costs while the direct cell arrangement within the housing maintains necessary structural support
Solution Approach 2:
By integrating heat sink functionality into the battery cell structure itself rather than using separate heat sink plates, the patent reduces component count and assembly steps, thereby lowering manufacturing costs while maintaining thermal management capabilities
3Quantity of substance
If multiple battery packs are required, then energy capacity increases, but weight and cost increase due to multiple frame structures
Solution Approach 1:
The patent creates a universal battery module design where the housing and cell arrangement can be scaled and configured in various pack compositions without requiring additional frame structures. This modular approach allows multiple battery packs to be assembled from standardized units, reducing the weight penalty associated with multiple separate frame structures
4Stability of the object's composition
If frame structure is used, then structural integrity is maintained, but device complexity increases
Solution Approach 1:
The patent eliminates the complex multi-component frame structure (including plastic frames, heat sink plates, and associated fastening elements) by directly arranging battery cells within the housing. This reduction in component count simplifies the device while maintaining structural integrity through the simplified direct-support architecture
