Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the diameter of the charging cable is increased to handle high current, then the temperature rise is controlled, but the volume and weight of the charging seat product increase
Solution Approach 1:
The patent introduces a liquid cooling system where cooling liquid flows through channels in the charging seat housing and charging cable to carry away heat. This hydraulic cooling approach enables effective heat dissipation without requiring increased cable diameter, thus controlling temperature rise while maintaining compact product dimensions.
Solution Approach 2:
The patent introduces cooling liquid as an intermediary substance that transfers heat from the charging cable and terminal to the external environment. This intermediary cooling medium enables heat dissipation without directly increasing the structural dimensions of the charging components.
2Temperature
If the diameter of the charging cable is increased to handle high current, then the temperature rise is controlled, but the cost increases
Solution Approach 1:
The liquid cooling system provides an alternative approach to heat management that does not require expensive thick-gauge cables. By introducing cooling channels and circulating coolant, the system achieves effective heat dissipation using standard cable specifications, thereby reducing material costs.
3Temperature
If a liquid cooled charging seat with containing chamber is used, then the cooling performance is improved, but the housing structure becomes complex and maintenance cost increases
Solution Approach 1:
The patent integrates the cooling channels directly into the charging seat housing structure itself, merging the housing and cooling system into a single integrated component. This eliminates the need for separate containing chambers and complex assembly, simplifying the overall structure while maintaining effective cooling performance.
Solution Approach 2:
The charging seat housing serves dual functions: it provides structural support and protection while simultaneously acting as the cooling channel pathway. This multi-functionality eliminates the need for dedicated cooling chambers, reducing structural complexity and maintenance requirements.
