Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature detector is simply attached to a relay terminal without additional structures, then the device complexity is low, but the temperature detection accuracy is insufficient
Solution Approach 1:
The patent introduces a fitting member as an intermediary component between the relay terminal and the temperature detector. This fitting member includes a holding portion that contacts the relay terminal and a spring portion that applies pressing force, serving as a mediator to ensure stable thermal contact and accurate temperature detection without requiring direct attachment of the detector to the terminal.
Solution Approach 2:
The spring portion is designed to be elastic and deformable, allowing it to dynamically adjust the pressing force applied to the relay terminal. This dynamic characteristic ensures continuous stable contact between the temperature detector and the relay terminal, maintaining accurate temperature detection while accommodating thermal expansion and contraction of the components.
2Measurement precision
If the spring portion applies strong pressing force to ensure stable contact, then the temperature detection accuracy improves, but the deformation of the spring portion increases
Solution Approach 1:
The fitting member is pre-assembled with the temperature detector before being installed on the relay terminal. The spring portion is pre-loaded with appropriate pressing force during assembly, ensuring that the optimal contact pressure is already established before the device begins operation. This preliminary action prevents excessive deformation during use while maintaining stable thermal contact.
3Strength
If the wall is made more rigid to provide stable support, then the structural strength increases, but the ability to apply consistent pressing force decreases
Solution Approach 1:
The wall structure is segmented into distinct functional portions: a rigid support portion that provides structural strength and stability, and a flexible spring portion that applies pressing force. This segmentation allows each portion to optimize its properties for its specific function - the rigid wall provides support while the elastic spring portion ensures stable contact between the temperature detector and relay terminal.
