Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging current is increased to improve charging speed, then the charging speed is improved, but the temperature rise inside the charging seat housing and the temperature of the charging cable becomes excessive
Solution Approach 1:
The patent extracts the heat management function from the charging seat housing by introducing a separate cooling box with cooling liquid circulation system. The cooling box is connected to the charging terminal and cable, allowing heat to be removed from these components through the cooling liquid flow, thereby addressing the temperature rise problem while maintaining high charging current
Solution Approach 2:
The patent introduces cooling liquid as an intermediary substance to transfer heat away from the charging terminal and cable. The cooling liquid circulates through the cooling box and absorbs heat from the high-current components, acting as a thermal mediator between the charging components and the environment, enabling high charging speeds without excessive temperature rise
2Temperature
If the diameter of the charging cable is increased to prevent excessive temperature rise, then the temperature control is improved, but the volume and weight of the charging seat product increase
Solution Approach 1:
The patent extracts the heat dissipation function from the charging cable itself by introducing a separate cooling box system. Instead of relying on increased cable diameter for thermal management, the cable is connected to the cooling box that actively removes heat through cooling liquid circulation, allowing the cable to maintain a compact diameter while achieving effective temperature control
Solution Approach 2:
The patent employs hydraulic cooling by circulating cooling liquid through the cooling box and cable connection. This fluid-based thermal management system efficiently removes heat from the charging components without requiring increased cable diameter, thereby maintaining lightweight construction while achieving superior temperature control
3Temperature
If the diameter of the charging cable is increased to prevent excessive temperature rise, then the temperature control is improved, but the volume of the charging seat product increases
Solution Approach 1:
The patent extracts the thermal management function from the charging seat housing structure by introducing a dedicated cooling box system. The cooling box with its cooling liquid circulation pathway provides active cooling for the terminal and cable, allowing the charging seat to maintain a compact volume without compromising temperature control capability
