Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional temperature sensors are installed in the inverter, then temperature monitoring is achieved, but installation space increases and securing becomes difficult
Solution Approach 1:
The temperature sensor is integrated directly into the rod-shaped signal connector, combining the signal transmission function and temperature sensing function into a single component. This eliminates the need for separate temperature sensor installations and reduces overall installation space while maintaining temperature monitoring capability.
Solution Approach 2:
The rod-shaped signal connector serves multiple functions: it provides electrical signal transmission and simultaneously acts as the mounting structure for the temperature sensor. The groove in the mount accommodates the rod-shaped signal connector while also providing the mounting position for the temperature sensor, achieving multi-functionality with a single structure.
2Measurement precision
If traditional temperature sensors are installed in the inverter, then temperature monitoring is achieved, but installation complexity increases
Solution Approach 1:
The temperature sensor is integrated directly into the rod-shaped signal connector, combining the signal transmission function and temperature sensing function into a single component. This eliminates the need for separate temperature sensor installations and reduces overall installation space while maintaining temperature monitoring capability.
Solution Approach 2:
The mount is pre-designed with a groove that accommodates the rod-shaped signal connector in a form-fitting and/or force-fitting manner. This preliminary structural preparation simplifies the installation process, as the components are designed to fit together without requiring additional complex securing elements or procedures.
3Reliability
If additional securing elements are used for temperature sensors, then securing reliability improves, but installation space and device complexity increase
Solution Approach 1:
The rod-shaped signal connector has a circular or rectangular cross-section that fits into the groove of the mount, creating a form-fitting connection. This geometric design provides inherent securing capability without requiring additional external securing elements, thereby maintaining reliability while reducing installation space.
Solution Approach 2:
The mount is pre-designed with a groove that accommodates the rod-shaped signal connector in a form-fitting and/or force-fitting manner. This preliminary structural preparation simplifies the installation process, as the components are designed to fit together without requiring additional complex securing elements or procedures.
