Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the cable is used to transmit electric energy from the energy storage component to the charging gun, then electric energy can be supplied to the charging gun, but the cable generates heat due to resistance which adversely affects charging efficiency
Solution Approach 1:
The cable is extracted from the cabinet body and routed externally through air inlets and air outlets, allowing it to be separated from the enclosed thermal environment. This extraction enables the cable to access external airflow for cooling while maintaining its electrical connection function between the energy storage component and charging gun.
Solution Approach 2:
Airflow acts as an intermediary cooling medium between the cable and the surrounding environment. The air inlets and air outlets serve as intermediary structures that facilitate the passage of airflow through the cabinet body, enabling heat exchange without direct thermal contact between internal components and external air.
2Temperature
If air vents are formed on the surface of the cabinet body to enable heat dissipation, then heat exchange efficiency is improved, but the overall outer contour size of the energy storage apparatus may increase
Solution Approach 1:
The air inlets and air outlets serve multiple functions: they enable cooling of the cable, facilitate airflow through the cabinet body, and can be integrated into the existing structural design of the cabinet. By designing these air passages to coincide with existing structural features, the patent avoids increasing the overall outer contour size while achieving effective heat dissipation.
3Temperature
If the cable passes through the air inlets for cooling, then heat exchange efficiency is improved, but the cable positioning stability may be affected
Solution Approach 1:
The cable is pre-routed through designated air inlets and air outlets during assembly, establishing fixed pathways before operation. This preliminary positioning ensures that the cable maintains stable contact with the airflow paths during charging operations, preventing random movement or displacement that would reduce cooling efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the temperature difference for effective heat exchange, reduces the adverse effects of high cable temperatures on charging efficiency, and maintains stable cable positioning for improved cooling and reduced structural impact.
Implementation Method 1
at least a portion of the cable passes through the air inlets so that the cable can directly dissipate heat and cool through the airflow entering through the air inlets
Implementation Method 2
The airflow for heat exchange with the cable is the normal temperature airflow from the outside, which helps increase the temperature difference between the airflow and the cable, improve the efficiency of heat exchange
