Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If twisted data transfer elements are used to reduce electromagnetic interference, then noise resistance is improved, but impedance matching capability deteriorates and re-tooling is required for different bandwidths
Solution Approach 1:
The connector is divided into separate functional modules: twisted pair elements for noise resistance and separate impedance matching circuits. This segmentation allows each module to independently perform its function without compromising the other.
Solution Approach 2:
The impedance matching circuits are designed to be adjustable rather than fixed, allowing the connector to dynamically adapt its impedance characteristics to match different bandwidth requirements and cable types, eliminating the need for re-tooling.
2Object-affected harmful factors
If conventional twisted pair connectors are used, then noise resistance is improved, but device complexity increases due to special handling requirements for re-tooling
Solution Approach 1:
The connector incorporates universal impedance matching circuits that can accommodate multiple cable types and bandwidth requirements through adjustment, making the same connector suitable for various applications without requiring specialized versions or re-tooling procedures.
3Ease of manufacture
If fixed impedance connectors are used, then manufacturing simplicity is improved, but adaptability to different bandwidths and impedances deteriorates
Solution Approach 1:
The impedance matching circuits incorporate adjustable elements that allow the connector to be configured for different impedance values and bandwidths while maintaining a standardized manufacturing process. The adjustability is built into the design rather than requiring custom manufacturing for each application.
