Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If connectors are made with traditional manufacturing methods, then production cost is high, but mechanical strength and structural stability are insufficient
Solution Approach 1:
The patent merges multiple components (flange element, matching element, coupling elements, housing seats) into a single integrated connector structure manufactured by die casting. This consolidation improves mechanical strength through unified construction while reducing production costs by eliminating separate manufacturing and assembly steps for individual components.
Solution Approach 2:
The patent changes the manufacturing parameter from traditional methods (machining, assembly) to die casting process. This parameter change enables production of complex geometries with high mechanical strength at lower cost, as die casting produces integrated parts with excellent structural properties without requiring subsequent assembly operations.
2Reliability
If coupling elements are provided without guided sliding mechanism, then device complexity is reduced, but relative movement causes incorrect clamping and signal loss
Solution Approach 1:
The patent introduces housing seats as intermediary guided sliding mechanisms between the coupling elements and the matching element. These housing seats provide precise geometric constraints that guide the coupling elements during insertion and clamping operations, ensuring accurate positioning and preventing relative movement that would cause signal loss, while the simple geometric design keeps overall structural complexity low.
3Manufacturing precision
If manual centering of microstrip line on conductive pin is performed, then alignment precision can be achieved, but assembly time and error rate increase
Solution Approach 1:
The patent implements self-centering through the geometric design of the housing seats and coupling elements. The symmetrical arrangement of these components creates inherent geometric constraints that automatically guide and center the microstrip line on the conductive pin during assembly, eliminating the need for manual centering operations while maintaining high alignment precision and significantly improving assembly efficiency.
4Reliability
If traditional connector designs are used, then simplicity is maintained, but mechanical stability and signal transmission quality deteriorate
Solution Approach 1:
The patent segments the connector into distinct functional elements (flange element for mounting, matching element for clamping, coupling elements for connection, housing seats for guidance) that work together in a coordinated manner. This segmentation allows each component to be optimized for its specific function, improving overall signal transmission quality and mechanical stability while the integrated die-cast construction prevents excessive complexity.

AI summary
A connector having a connection element configured to couple with a coaxial cable, the connection element including a body that houses a signal-transmission portion, an interface body connectable with the connection element and including a through-hole for the passage of the signal-transmission portion coming from the connection element, and a matching element configured to mechanically couple with the interface body and cause, when coupled with the interface body, the clamping of a board associable with the connector and adapted to receive the signal of the signal-transmission portion. The matching element includes at least two coupling elements and the interface body includes at least two respective housing seats configured to receive and engage with the coupling elements, the housing seats being configured to allow a guided sliding of the coupling elements therein.
