Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed cooling pipe configuration is used, then the device complexity is reduced, but the adaptability to different battery cell or electrical component arrangements deteriorates
Solution Approach 1:
The cooling block is designed with movable or adjustable positioning mechanisms that allow it to be repositioned along the cooling pipe according to different heat generation locations. This dynamic adjustment capability enables the cooling system to adapt to various battery cell or electrical component arrangements without requiring multiple fixed cooling pipe configurations, thus resolving the contradiction between device complexity and adaptability.
2Manufacturing precision
If the cooling block position is fixed, then the manufacturing precision is improved, but the adaptability to varying heat generation positions deteriorates
Solution Approach 1:
The cooling system is divided into modular components: a fixed cooling pipe structure and a movable cooling block. The cooling block can be segmented into multiple positions or modules that can be independently positioned and fixed at different locations along the cooling pipe, allowing precise manufacturing for each position while maintaining overall system adaptability.
Solution Approach 2:
The cooling block incorporates adjustable positioning mechanisms that enable it to be dynamically repositioned to match varying heat generation locations. This dynamic capability allows the system to maintain high manufacturing precision at each specific position while adapting to different operational configurations.
3Device complexity
If simple cooling methods are used for electrical components, then the device complexity is reduced, but the cooling efficiency deteriorates
Solution Approach 1:
The cooling system merges the cooling functions for both battery cells and electrical components into a single integrated system. The cooling pipe and cooling block serve dual purposes: cooling battery cells through direct contact and cooling electrical components through the same cooling medium, thereby improving cooling efficiency without significantly increasing device complexity.
