Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional network sockets use printed circuit boards for routing electrical signals, then electrical connection quality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates the printed circuit board from the network socket structure. Instead of using a PCB to route electrical signals between contact pins, the invention uses direct spatial arrangement and routing of the contact pins themselves to achieve signal transmission, thereby removing the complex PCB component while maintaining electrical connection quality
Solution Approach 2:
The patent merges the functions of the contact pins and the routing structure. The contact pins are designed to both make electrical contact and simultaneously serve as the routing path for electrical signals, eliminating the need for a separate PCB routing layer. This integration simplifies the overall structure while maintaining reliable electrical connections
2Reliability
If electrical signals are routed through conventional PCB paths, then signal transmission is achieved, but signal crosstalk increases at high frequencies
Solution Approach 1:
The patent segments the contact pins into different spatial groups or layers, arranging them in a configuration that separates signal paths. This segmentation allows electrical signals to be routed through distinct spatial zones, reducing electromagnetic interference and crosstalk between adjacent signals while maintaining effective signal transmission
Solution Approach 2:
The patent transitions from conventional two-dimensional PCB routing to a three-dimensional spatial arrangement of contact pins. By utilizing vertical and lateral spacing in multiple dimensions, the design creates greater separation between signal paths, reducing crosstalk at high frequencies while maintaining compact overall dimensions
3Reliability
If printed circuit boards are used for signal routing, then electrical connection is ensured, but manufacturing cost increases
Solution Approach 1:
The patent removes the printed circuit board component entirely from the network socket assembly. The electrical connection function previously performed by the PCB is replaced by a simplified structure using directly arranged contact pins with integrated routing, reducing component count and manufacturing complexity while maintaining connection reliability
Solution Approach 2:
The contact pins are designed to perform multiple functions simultaneously: making electrical contact, providing mechanical support, and routing electrical signals. This multi-functionality eliminates the need for separate PCB routing structures, simplifying manufacturing and reducing overall production costs while ensuring reliable electrical connections
