Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery modules for large-sized devices or vehicles face challenges in achieving high cooling performance and light weight while maintaining effective coupling strength to prevent leakage in the cooling path, especially when using composite materials with heterogeneous components.
Innovation Solution
The battery module design incorporates a module housing with a main edge part surrounding an accommodation space, featuring a first plate with a matching structure that includes holes, protruding portions, or an uneven pattern to enhance coupling strength and prevent leakage, along with a second plate forming the other side of the cooling path, using composite materials like metal and resin for improved heat conduction and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If composite materials including heterogeneous materials are used to reduce weight, then weight is reduced, but coupling strength between materials deteriorates leading to potential leakage
Solution Approach 1:
The patent applies local quality by creating a matching structure with different properties at different locations of the heterogeneous materials. The matching structure includes a first portion and a second portion with different geometries that interlock to provide enhanced coupling strength at the interface between heterogeneous materials, while the bulk materials maintain their lightweight properties.
Solution Approach 2:
The patent uses composite materials by combining heterogeneous materials (different material types) to achieve both weight reduction and improved coupling strength. The matching structure facilitates the bonding of these heterogeneous materials through complementary geometric features that enhance mechanical interlocking.
2Temperature
If cooling path is implemented for high cooling performance, then cooling performance is improved, but leakage risk increases due to weak coupling between components
Solution Approach 1:
The matching structure applies local quality by concentrating the coupling enhancement at the critical interface regions where leakage could occur. The first and second portions of the matching structure are positioned to provide localized reinforcement exactly where the cooling path sealing is most vulnerable.
Solution Approach 2:
The matching structure employs curved or inclined interfaces between the first and second portions, creating tapered or rounded transition zones that improve stress distribution and sealing effectiveness in the cooling path, reducing leakage risk while maintaining cooling performance.
3Weight of moving object
If heterogeneous materials are used to achieve light weight, then weight is reduced, but manufacturing complexity increases due to coupling challenges
Solution Approach 1:
The matching structure is designed and prepared in advance as an integral part of the heterogeneous material components. The first and second portions are formed during the molding or fabrication process, eliminating the need for complex post-assembly operations to ensure proper coupling between heterogeneous materials.
Solution Approach 2:
The matching structure merges the coupling function with the structural components themselves. Rather than adding separate fastening or bonding mechanisms, the first and second portions are integrated into the design of the heterogeneous material components, simplifying the manufacturing process.
