Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional devices for adjusting electric parameters are used, then the device structure is complete and functional, but the size of the signal input end cannot be adjusted leading to increased signal path length and high insert loss
Solution Approach 1:
The base is designed to be rotatable relative to the positioning body, allowing dynamic adjustment of the terminal pair position. This enables the signal input end size to be adjusted by changing the base orientation, thereby optimizing the signal path length and reducing insert loss without compromising the complete device functionality.
Solution Approach 2:
The invention introduces rotational movement as an additional degree of freedom to adjust the effective size of the signal input end. By rotating the base around the positioning body, the device can optimize its spatial configuration, effectively reducing the signal path length in the critical dimension while maintaining all necessary electrical connections.
2Ease of operation
If conventional devices for adjusting electric parameters are used, then the device is functional, but adjustment of the device is inconvenient
Solution Approach 1:
The rotatable base provides a simple dynamic adjustment mechanism that allows convenient repositioning of terminal pairs. The rotation capability enables easy adjustment of electric parameters by simply changing the base orientation, making the device user-friendly while avoiding complex adjustment mechanisms.
3Ease of manufacture
If conventional devices for adjusting electric parameters are used, then the device provides electric parameter adjustment, but the production cost is high
Solution Approach 1:
The device is segmented into distinct functional components: a positioning body with signal terminals, a rotatable base with terminal pairs, and an elastic body for fastening. This segmentation allows for simplified manufacturing of individual components while maintaining reliable electrical connections and electric performance through the modular assembly approach.
Solution Approach 2:
The elastic body serves as an intermediary element that provides reliable electrical connection and mechanical fastening between the base and positioning body. This simple intermediary component ensures reliable electric performance while being inexpensive to manufacture, thereby reducing overall production cost.
