Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductive terminals use a complex design structure with separate mounting portions and mating portions perpendicular to each other, then the connector provides stable mounting and mating capabilities, but the manufacturing complexity and structural complexity increase
Solution Approach 1:
The patent merges the mounting portion and mating portion into a single linear structure. The conductive terminal features a tail portion for mounting, a connection portion, and a mating portion, all extending along the same axis. This eliminates the need for perpendicular arrangements of separate portions, simplifying the overall structure while maintaining both mounting stability and mating functionality through the integrated linear design
2Ease of manufacture
If the conductive terminals use a simplified linear design with all portions extending along the mating direction, then the manufacturing complexity is reduced, but the shielding effectiveness and signal transmission quality may be compromised
Solution Approach 1:
The patent implements a nested shielding structure where metal shields are positioned around the conductive terminals. The shields include side shields extending from the insulating bracket and end shields positioned at the ends, creating nested shielding zones. This nested arrangement provides comprehensive electromagnetic shielding for the linear conductive terminals, maintaining signal transmission quality while allowing the simplified linear terminal structure
Solution Approach 2:
The shielding structure is segmented into multiple components: side shields extending from the insulating bracket, end shields positioned at terminal ends, and additional shielding elements. This segmentation allows each shield component to address specific shielding needs at different locations, providing comprehensive protection for the simplified linear conductive terminals while maintaining manufacturing simplicity
