Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If signals are transmitted through multiple terminals in parallel, then data transmission speed increases, but signal interference between terminals increases
Solution Approach 1:
A metal shielding sheet is introduced as an intermediary component positioned between adjacent terminal groups. This shielding sheet acts as a mediator that blocks electromagnetic signals from one terminal group from interfering with adjacent terminal groups, thereby reducing signal interference while maintaining high-speed parallel transmission capability
Solution Approach 2:
The connector is divided into multiple independent terminal groups with each group spatially separated and electrically isolated from others through the metal shielding sheet. This segmentation allows signals to be transmitted in parallel across multiple groups without mutual interference, enabling high data transmission speeds while preventing cross-terminal signal coupling
2Productivity
If terminal width is reduced to fit more terminals, then transmission capacity increases, but signal stability decreases
Solution Approach 1:
The metal shielding sheet is positioned locally between adjacent terminal groups rather than uniformly across all terminals. This localized shielding approach provides targeted electromagnetic isolation where interference occurs most, maintaining signal stability for each terminal while allowing the overall connector to accommodate more terminals for increased transmission capacity
3Speed
If more terminals are added to increase data rate, then transmission speed increases, but device complexity increases
Solution Approach 1:
The metal shielding sheet serves multiple functions simultaneously: it provides electromagnetic shielding between terminal groups, acts as a structural support element, and facilitates heat dissipation. This multi-functionality allows the connector to achieve high data transmission speeds with multiple terminals without proportionally increasing structural complexity, as a single component addresses multiple design requirements
