Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable connectors are used in high-speed data transmission, then signal transmission can be achieved, but signal quality deteriorates due to connection discontinuity and impedance mismatch
Solution Approach 1:
The patent merges the connector body and contact structure into an integrated plug assembly, where the plug directly connects the cable inner conductor to the circuit board contact. This integration eliminates intermediate connection elements, reduces connection discontinuity, and maintains impedance matching for high-speed signal transmission.
Solution Approach 2:
The connector is segmented into distinct functional parts: the socket with opening for circuit board mounting, the plug with fixing member for cable attachment, and the elastic connection member for electrical contact. This segmentation allows each part to be optimized for its specific function while working together to achieve reliable high-speed transmission.
2Adaptability or versatility
If the connection length is increased to accommodate complex system layouts, then wiring flexibility improves, but signal transmission quality deteriorates due to increased discontinuity
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement by positioning the socket opening, plug, and elastic contact member in specific orientations. This dimensional optimization allows the connector to adapt to complex system layouts while maintaining minimal effective connection length for signal integrity.
3Reliability
If precise cable connectors are used to transmit high-speed differential signals, then signal transmission quality improves, but manufacturing and assembly difficulty increases
Solution Approach 1:
The elastic connection member automatically establishes electrical contact when the plug is inserted into the socket, eliminating the need for precise manual alignment or additional fastening steps. The elasticity provides self-adjusting contact pressure, ensuring reliable connection without complex assembly procedures.
