Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcement member is added to protect the battery from collision, then the battery protection is improved, but the number of components increases
Solution Approach 1:
The patent combines the holding member and reinforcement member into a single integrated structure. The holding member that secures the cylindrical cells also serves as the reinforcement member that protects the battery from collision, eliminating the need for separate protection components while maintaining both holding and protection functions
Solution Approach 2:
The holding member is designed to perform multiple functions simultaneously: it holds the cylindrical cells in position, provides structural reinforcement to protect against collision, and facilitates heat dissipation. This multi-functional design resolves the contradiction by achieving battery protection without adding extra components
2Volume of moving object
If cells are oriented with axial direction matching vehicle width, then space utilization is improved, but reinforcement members are required for collision protection
Solution Approach 1:
The holding member integrates both the cell holding function and the collision protection function into a single component structure, allowing efficient space utilization while eliminating the need for separate reinforcement members
3Stability of the object's composition
If a holding member is used to secure cells, then cell positioning is improved, but the number of components increases
Solution Approach 1:
The holding member is designed as a multi-functional component that simultaneously provides cell positioning, collision protection, and heat dissipation capabilities, thereby achieving stable cell positioning without increasing the overall number of components in the battery assembly
