Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical connectors are used for high-frequency transmission, then the connector structure is simple, but signal transmission stability and quality deteriorate
Solution Approach 1:
The patent merges the filter function with the connector structure by integrating circuit boards with filtering electronic components directly into the connector assembly. This combination allows the connector to simultaneously provide mechanical connection and signal filtering capabilities, resolving the contradiction between maintaining simple connector structure and achieving reliable high-frequency signal transmission.
2Reliability
If electronic filter devices are installed in the circuit board for high-frequency transmission, then signal transmission quality improves, but internal space is occupied
Solution Approach 1:
The filter device is merged with the connector body, where circuit boards containing filtering electronic components are integrated into the connector assembly. This integration allows the filtering function to be achieved without occupying additional internal space in the equipment, as the filter becomes part of the connector structure itself.
3Volume of moving object
If filter function is integrated into the connector, then internal space is saved, but connector structure becomes more complex
Solution Approach 1:
The connector is segmented into modular components including a connector body, circuit boards, and terminal blocks. This segmentation allows the filtering function to be integrated through separately manufacturable circuit boards that are assembled into the connector, thereby limiting the increase in overall structural complexity while achieving space savings.
4Ease of manufacture
If conventional connectors are used, then fabrication is simple, but signal filtering capability is lacking
Solution Approach 1:
The connector fabrication process is segmented into standard steps for manufacturing the connector body and separate steps for assembling circuit boards with filtering components. This segmentation maintains fabrication simplicity by using conventional manufacturing techniques for each component while adding the necessary filtering capability through the integrated circuit boards.
