Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the clock rate is increased to improve transmission rate, then the transmission rate is improved, but the connection stability deteriorates
Solution Approach 1:
The conductive member is divided into two segments with a protrusion tooth structure between them, allowing independent adjustment and optimization of each segment's contact with the conductive groove, thereby maintaining stable connection at high transmission rates
Solution Approach 2:
The protrusion tooth and tooth recess structures add a dimensional feature to the conductive member and groove interface, creating multiple engagement points that enhance connection stability without limiting transmission rate
2Speed
If the bandwidth is increased to improve transmission rate, then the transmission rate is improved, but the terminal connection stability deteriorates
Solution Approach 1:
The protrusion tooth is pre-formed on the conductive member and the tooth recess is pre-formed on the conductive groove, ensuring proper alignment and engagement before the terminal assembly is fully inserted, thereby maintaining connection stability at high bandwidths
Solution Approach 2:
The protrusion tooth and tooth recess act as intermediary engagement features between the conductive member and conductive groove, providing a mechanical interface that ensures stable connection under high bandwidth conditions
3Reliability
If the engagement force is increased to improve connection stability, then the connection stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The protrusion tooth structure is integrated directly into the conductive member as a single molded feature rather than a separate component, and the tooth recess is integrated into the conductive groove, simplifying manufacturing while maintaining engagement force
Solution Approach 2:
The protrusion strip width and tooth geometry parameters are optimized to provide sufficient engagement force for connection stability while maintaining compatibility with standard manufacturing processes
4Reliability
If the contact area is increased to improve terminal connection stability, then the connection stability is improved, but the manufacturing time increases
Solution Approach 1:
The terminals are pre-formed with inset molding structures that automatically align with the conductive member during assembly, eliminating the need for post-assembly adjustments and reducing manufacturing time while ensuring stable contact
Solution Approach 2:
The inset molding structure of the terminals self-aligns with the protrusion strip during insertion, allowing the assembly process to automatically achieve proper contact alignment without additional manufacturing steps

AI summary
A PSAS female connector includes a body member, a terminal assembly, and a conductive member. The body member has a conductive groove and a tooth recess. The conductive groove is on a lateral side of the body member. The tooth recess is at an inner side of an edge of the conductive groove. The conductive member has a protrusion tooth and a protrusion strip, and is engaged in the conductive groove. The protrusion tooth is at an outer side of an edge of the conductive member. When the conductive member is engaged in the conductive groove, the protrusion tooth is geared to be engaged with the tooth recess. When the terminal assembly is engaged in the terminal groove, the protrusion strip and the terminal assembly are engaged with each other, thus improving the combination between the conductive member and the conductive groove.
