Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-emphasis or de-emphasis is used to compensate for high frequency loss, then signal transmission performance is improved, but power consumption increases and electromagnetic radiation is emitted
Solution Approach 1:
The patent extracts the equalization function from active electronic circuits and implements it through passive RC networks integrated into the connector structure. This separates the equalization function from power-consuming active components, achieving signal compensation without additional power consumption.
Solution Approach 2:
The RC equalization networks are designed to automatically compensate for high-frequency loss through their inherent electrical characteristics. The passive components self-regulate the frequency response without requiring external power supply or control signals,实现ing self-service equalization.
2Reliability
If pre-emphasis or de-emphasis is used to compensate for high frequency loss, then signal transmission performance is improved, but electromagnetic radiation increases

3Reliability
If complex equalization circuits are used to compensate for high frequency loss, then signal transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent merges the equalization function with the connector structure by integrating RC networks directly into the connector housing. This combines two separate functions (connection and equalization) into a single integrated component, reducing overall system complexity while maintaining equalization performance.
Solution Approach 2:
The connector is designed to perform multiple functions simultaneously: mechanical connection, electrical conduction, and signal equalization. The RC networks are integrated into the connector body, making the connector a multi-functional component that provides equalization without requiring separate circuit boards or active components.
