Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector design is used, then the structure is simple, but electromagnetic interference and signal degradation occur in high-frequency applications
Solution Approach 1:
The connector is divided into multiple independent contact units, each handling specific signal pairs. This segmentation allows for better electromagnetic isolation between signal paths while maintaining overall connector functionality, directly addressing the signal degradation issue in high-frequency applications.
Solution Approach 2:
Conductive shells are nested around individual contact units, creating a nested structure where smaller conductive elements are positioned within larger protective housings. This nested arrangement provides effective electromagnetic shielding for each contact unit while maintaining a compact overall form factor.
2Productivity
If multiple signal pairs are transmitted in parallel, then data transmission capacity increases, but noise mixing and signal attenuation worsen
Solution Approach 1:
Signal pairs are separated into distinct contact units with individual conductive shielding, preventing electromagnetic interference between adjacent signal paths. This segmentation enables higher parallel transmission capacity without compromising signal integrity through noise mixing.
Solution Approach 2:
Conductive shells act as intermediary shielding elements between adjacent signal contacts, blocking electromagnetic fields from interfering with neighboring signal pairs. This intermediary shielding structure allows dense parallel arrangement of contacts while maintaining signal quality.
3Object-affected harmful factors
If shielding structures are added to reduce interference, then electromagnetic protection improves, but space occupation increases
Solution Approach 1:
Conductive shells are integrated in a nested configuration around individual contact units, maximizing shielding effectiveness within minimal space. The nested structure allows shielding elements to be positioned concentrically around contacts, providing comprehensive electromagnetic protection without significantly increasing the connector's overall volume.
Solution Approach 2:
Shielding is applied locally to each contact unit rather than using a single large shield for the entire connector. This localized shielding approach provides effective electromagnetic protection where needed while minimizing overall space occupation, as each shell only encloses its specific contact unit.
