Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a thermal truss is added to rapidly transfer thermal energy to the temperature sensor, then temperature detection speed is improved, but device complexity increases
Solution Approach 1:
The thermal truss acts as an intermediary component between the power conductor terminal and the temperature sensor. It rapidly conducts thermal energy from the terminal to the sensor, enabling fast temperature detection without requiring the sensor to be in direct contact with the terminal, thus resolving the contradiction between detection speed and device complexity
Solution Approach 2:
The thermal management system is segmented into distinct functional components: the power conductor terminal, the thermal truss for heat transfer, and the temperature sensor for detection. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the added complexity
2Reliability
If thermal management measures are implemented, then safety and performance are improved, but device complexity increases
Solution Approach 1:
The system implements thermal feedback by continuously monitoring the temperature of the power conductor terminal through the temperature sensor and thermal truss. This feedback mechanism enables real-time detection of temperature changes and allows for corrective actions to be taken, improving safety and performance while managing the complexity through automated monitoring
Solution Approach 2:
The thermal truss is pre-configured to rapidly conduct heat from the terminal to the sensor before critical overheating occurs. This preliminary thermal pathway establishment enables proactive temperature management, allowing the system to take preventive measures before thermal issues compromise safety or performance

AI summary
Systems and methods are provided for thermal management of a thermal monitoring and control plug. The plug may be used to connect an electric vehicle to an electrical energy source in order to charge the electric vehicle. To ensure real-time, accurate temperature monitoring of the thermal monitoring and control plug, a temperature detection system may be used. The temperature detection system may include a thermal truss at least partially surrounding a power conductor terminal of the thermal monitoring and control plug. A temperature sensor may be coupled to the thermal truss and configured to rapidly detect the temperature change of the power conducting terminal.
