Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the diameter of the charging cable is increased to handle high current, then the charging speed and current capacity are improved, but the volume and weight of the charging seat product increase
Solution Approach 1:
The patent extracts the heat generation problem from the charging cable and terminal by introducing a separate cooling box system. The cooling box contains cooling liquid and cooling components that actively remove heat from the charging terminal and cable, allowing the use of thinner cables without overheating issues.
Solution Approach 2:
The patent introduces cooling liquid as an intermediary substance between the charging terminal/cable and the environment. The cooling liquid absorbs heat from the charging components through thermal contact and transfers it away, enabling high current operation without increasing cable diameter.
2Power
If the diameter of the charging cable is increased to handle high current, then the charging speed and current capacity are improved, but the weight of the charging seat product increases
Solution Approach 1:
The patent extracts the heat management function from the charging cable itself and places it in a separate cooling box system. This allows the cable to remain lightweight while still handling high currents, as the cooling infrastructure is separated from the cable mass.
Solution Approach 2:
The cooling liquid acts as an intermediary that carries heat away from the charging components without requiring the cable itself to be heavier. The cooling system's weight is distributed separately from the cable mass.
3Power
If the diameter of the charging cable is increased to handle high current, then the charging speed and current capacity are improved, but the cost of the charging seat product increases
Solution Approach 1:
The patent extracts the cooling function from the cable assembly and implements it as a separate, reusable cooling box system. This modular approach allows the expensive cooling infrastructure to be shared across multiple charging operations rather than requiring expensive, thick cables for each connection.
Solution Approach 2:
The cooling box is designed as a universal component that can serve multiple charging terminals and cables. Once the cooling box is purchased, it can be used repeatedly with different charging equipment, reducing the per-use cost compared to buying expensive thick cables for each high-power charging need.
4Temperature
If a cooling system is integrated into the charging seat, then the temperature control is improved, but the device complexity increases
Solution Approach 1:
The patent segments the cooling system into a separate, detachable cooling box that can be removed from the charging seat. This segmentation allows the cooling functionality to be added without permanently complicating the charging seat structure, as the cooling components are housed in a separate unit that interfaces with the terminal.
Solution Approach 2:
The cooling box acts as an intermediary device that bridges the charging seat and the cooling liquid reservoir. It contains the cooling components and liquid, providing a self-contained temperature control system that doesn't require integration into the main charging seat structure.

Function Achieved in This Case
This solution effectively cools the charging terminal and cable by transferring heat quickly to the cooling liquid, reducing the need for larger cable diameters and minimizing weight and cost increases.
Implementation Method 1

AI summary
The present invention discloses a charging terminal fixing component, a top cover assembly, a charging terminal cooling box, and a charging seat. The charging terminal fixing component comprises of a frame (129) adapted to be fixed to a charging terminal cooling box (1); and a fixing structure (120) which is formed on the top of the frame (129) for fixing a charging terminal (3) to the charging terminal cooling box (1). The fixing structure (120) comprises of a pair of side plates (121), with their bottom connected to the top of the frame (129); a pair of top plates (122) respectively connected to the top of the pair of side plates (121); and a pair of elastic buckles (123) respectively connected to the top of the pair of side plates (121). The pair of top plates (122) are adapted to rest against the top surface of a welding end (31) of the charging terminal (3) inserted between the pair of side plates (121), so that the bottom surface of the welding end (31) of the charging terminal (3) is in thermal contact with a top cover (11) of the charging terminal cooling box (1); the pair of elastic buckles (123) are used to respectively engage with a pair of snap slots (31a) on the welding end (31) of the charging terminal (3), to lock the welding end (31) of the charging terminal (3) to the top cover (11) of the charging terminal cooling box (1). In the present invention, the charging terminal fixing component fixes the charging terminal to the top cover of the charging terminal cooling box, so that the heat of the charging terminal can be quickly transferred to the cooling liquid inside the charging terminal cooling box through the top cover, thereby achieving rapid cooling of the charging terminal.
