Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two layers of terminals are arranged in the electrical connector, then the connector can provide electric connection and signal transmission functions, but mutual crosstalk interference is easily caused which affects high-frequency performance
Solution Approach 1:
The electrical connector is divided into upper and lower terminal sets that are spatially separated by a partition plate. The partition plate physically segments the terminal arrangements, isolating the upper terminal set from the lower terminal set to prevent electromagnetic interference and crosstalk between signals.
Solution Approach 2:
A partition plate is introduced as an intermediary structure between the upper and lower terminal sets. This partition plate acts as a shield that blocks electromagnetic fields and prevents direct interference between adjacent terminals, thereby eliminating crosstalk while maintaining signal transmission functionality.
2Speed
If terminals are arranged in layers for high-speed transmission, then signal transmission speed is improved, but crosstalk interference increases which degrades performance
Solution Approach 1:
The terminal structure is segmented into distinct upper and lower layers separated by partition plates. This segmentation allows high-speed signals to be transmitted through multiple terminals simultaneously while preventing interference between layers, thus maintaining both speed and reliability.
Solution Approach 2:
Partition plates serve as intermediary shielding structures between terminal layers. These plates block electromagnetic interference while allowing high-speed signal transmission through the terminal interfaces, resolving the contradiction between transmission speed and signal integrity.
3Object-affected harmful factors
If a partition plate is added between terminal sets to isolate them, then crosstalk is reduced, but the device complexity increases
Solution Approach 1:
The partition plate is integrated with the molding piece as a unified structure. The partition plate and molding piece form a combined component that provides both structural support and electromagnetic shielding, reducing the number of separate parts and simplifying assembly while maintaining crosstalk isolation functionality.
Solution Approach 2:
The partition plate serves multiple functions simultaneously: it provides structural support for terminal positioning, acts as an electromagnetic shield to prevent crosstalk, and integrates with the molding piece to form a unified connector body. This multi-functionality reduces overall device complexity despite adding shielding capability.
