Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature sensor is placed on the heat sink, then the temperature measurement is easier to implement, but the measurement accuracy deteriorates due to being far from the components
Solution Approach 1:
The housing body serves as an intermediary structure that brings the temperature sensor into close proximity with the electrical component through the support point arrangement, while the housing material provides electrical insulation. This mediator approach enables accurate temperature measurement near the component without direct electrical contact issues.
2Measurement precision
If the temperature sensor is placed inside the module on the circuit carrier, then the temperature measurement accuracy improves, but the electrical insulation reliability deteriorates and valuable space is occupied
Solution Approach 1:
The housing body acts as an intermediary structure that holds the temperature sensor close to the electrical component through the support point, achieving accurate temperature measurement while maintaining electrical insulation through the housing material, without occupying circuit carrier space.
Solution Approach 2:
The temperature sensor is positioned in a different spatial dimension (outside the module, attached to the housing body at the support point) rather than on the circuit carrier plane, enabling close thermal contact with the component while maintaining electrical insulation and avoiding circuit carrier space occupation.
3Measurement precision
If the temperature sensor is placed close to the electrical component, then the temperature measurement accuracy improves, but the electrical insulation difficulty increases
Solution Approach 1:
The housing body serves as an intermediary structure between the temperature sensor and the electrical component, enabling close proximity for accurate temperature measurement while the housing material itself provides the electrical insulation function.
Solution Approach 2:
The housing body has different functional properties at different locations: at the support point it provides thermal contact for temperature sensing, while the housing material generally provides electrical insulation. This local differentiation of properties enables both accurate measurement and electrical safety.
