Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent cooling devices are arranged in both the battery compartment and electrical compartment, then the energy storage device and power distribution box can be cooled independently, but the structure becomes complex and manufacturing costs increase
Solution Approach 1:
The patent combines the cooling functions for the energy storage device and power distribution box into a single integrated cooling device. The cooling device includes a cooling component arranged in the electrical compartment and a heat exchange component arranged in the battery compartment, which are connected through a refrigerant circulation system. This merging approach maintains independent cooling capability while reducing structural complexity and manufacturing costs.
Solution Approach 2:
The integrated cooling device serves multiple functions: it cools the power distribution box through the cooling component in the electrical compartment, and it cools the energy storage device through the heat exchange component in the battery compartment. The single device performs what would traditionally require two separate cooling systems, achieving multi-functionality and reducing overall system complexity.
2Reliability
If independent cooling devices are arranged in both the battery compartment and electrical compartment, then each component can be cooled independently, but manufacturing costs increase
Solution Approach 1:
The patent merges two independent cooling devices into one integrated cooling device, reducing the number of components that need to be manufactured and assembled. The integrated design includes shared elements such as the refrigerant circulation system, control unit, and housing structure, which reduces manufacturing complexity and cost while maintaining the ability to independently cool both the energy storage device and power distribution box.
3Reliability
If independent cooling devices are arranged in both the battery compartment and electrical compartment, then cooling can be optimized for each component, but energy consumption increases
Solution Approach 1:
The integrated cooling device reduces energy consumption by eliminating redundant components and optimizing the refrigerant circulation path. The single compressor and refrigerant loop serve both cooling needs, reducing the total energy required compared to two independent cooling systems. The control unit intelligently manages the refrigerant flow to optimize cooling efficiency for both the power distribution box and energy storage device simultaneously.
