Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate impact detection means are added to the battery system, then the detection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The cooler is designed to perform multiple functions: thermal management through cooling channels and impact detection through pressure detection channels. By integrating these functions into a single component, the system achieves improved detection capability without adding separate impact detection means, thus avoiding increased device complexity and cost
Solution Approach 2:
The patent combines the cooling function and impact detection function into a single cooler component. The cooling channels and pressure detection channels are integrated within the same structural element, merging two previously separate systems into one unified component that reduces overall system complexity
2Device complexity
If the cooler is integrated with pressure detection channels, then the device complexity is reduced, but the cooling performance may be compromised
Solution Approach 1:
The cooler is segmented into distinct functional zones with separate cooling channels and pressure detection channels. This segmentation allows each channel type to perform its specific function independently without interfering with the other, maintaining optimal cooling performance while achieving functional integration
Solution Approach 2:
Different regions of the cooler are designed with different local qualities: cooling channels are positioned and dimensioned for optimal heat dissipation, while pressure detection channels are positioned and dimensioned for optimal impact sensing. This localized optimization ensures that integration does not compromise either function
