Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature sensors are attached using screws, then the temperature measurement function is achieved, but the assembly process is complex and prone to misassembly errors
Solution Approach 1:
The patent extracts the fastening function from the traditional screw-based assembly system. The sensor assembling part is designed as an integrated structure that combines the mounting function with the sensor holder, eliminating the need for separate screws and fastening operations. This reduces assembly complexity and minimizes misassembly errors while maintaining reliable temperature measurement.
2Ease of operation
If a simple insertion method is used, then the ease of assembly is improved, but the secure attachment of the temperature sensor cannot be ensured
Solution Approach 1:
The patent employs a dynamic elastic structure in the sensor assembling part that automatically adjusts to secure the temperature sensor. The elastic member deforms during insertion to allow easy placement, then restores its original shape to apply continuous holding force, ensuring reliable attachment. This dynamic mechanism combines the ease of simple insertion with the security of firm fixation.
3Measurement precision
If the temperature sensor is firmly fixed, then the measurement precision is improved, but the assembly process becomes more difficult
Solution Approach 1:
The sensor assembling part is designed to perform the firm fixation function automatically through its own elastic deformation characteristics. When the temperature sensor is inserted, the elastic member self-adjusts to apply the necessary holding force, ensuring precise contact between the sensor and measurement surface. This self-service mechanism achieves precise measurement without requiring complex external fixation systems.
