Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power terminals and signal terminals are used in conventional electrical connectors, then reliable power and signal transmission is achieved, but the feature dimension of the electrical connector increases
Solution Approach 1:
The electrical connector is segmented into distinct power terminal components and signal terminal components, each optimized for their specific function. The power terminals include clamp arm structures for robust electrical connection, while signal terminals use resistive contact structures for precise signal transmission. This segmentation allows each component to be minimized in size according to its specific requirements rather than being constrained by a uniform connector size.
Solution Approach 2:
Different terminal structures are applied to different parts of the connector based on local requirements: power terminals use clamp arm structures with higher mechanical strength and contact pressure for power transmission, while signal terminals use resistive contact structures with lower contact resistance for signal integrity. This local differentiation enables size optimization in each region without compromising overall reliability.
2Adaptability or versatility
If multiple power and signal patterns are transmitted through the electrical connector, then functional requirements of modern electronic products are met, but the number of terminals increases and feature dimension cannot be reduced
Solution Approach 1:
The connector design incorporates multiple power terminals and signal terminals that can be configured to support various power and signal patterns. The modular terminal structures allow the same basic connector framework to accommodate different numbers and arrangements of terminals, providing universality across multiple application scenarios without requiring different connector sizes.
Solution Approach 2:
The terminal arrangements utilize three-dimensional spatial optimization within the connector body. Terminals are positioned in multiple layers and angles, allowing multiple power and signal patterns to be transmitted through a compact footprint by utilizing vertical and angular dimensions rather than only horizontal expansion.
