Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is designed as a passive four-terminal circuit network to improve frequency and reflection characteristics, then the connector's own electrical characteristics are optimized, but the connector is still electrically affected by external circuits and transmission lines, requiring specialized design know-how and resulting in variable performance
Solution Approach 1:
The patent introduces an active circuit (amplifier or buffer) as an intermediary element within the connector. This active circuit acts as a mediator that isolates the input and output sides electrically, preventing external circuits and transmission lines from mutually influencing each other through the connector. The active circuit maintains impedance matching and signal integrity while blocking the propagation of electrical effects between sides, thus resolving the contradiction between achieving reliable electrical characteristics and reducing design complexity.
Solution Approach 2:
The connector with an active circuit performs self-service by automatically compensating for electrical interactions with external circuits. The active circuit continuously maintains proper impedance matching and signal levels without requiring the designer to manually account for parasitic elements and external circuit effects. This self-adjusting capability eliminates the need for specialized design know-how and ensures consistent performance across different installation scenarios.
2Speed
If high-speed and wideband pulse signals are transmitted through a passive connector, then signal transmission speed is achieved, but the signals are sensitive to parasitic elements and external circuit influences, requiring careful component mounting and circuit pattern design
Solution Approach 1:
The active circuit serves as a mediator that isolates the high-speed signal path from parasitic elements and external circuit influences. By placing an amplifier or buffer within the connector, the signal transmission maintains high speed while the active circuit prevents degradation from parasitic capacitance, inductance, and resistance. This isolation eliminates the need for extremely precise component mounting and circuit pattern design, as the active circuit compensates for these effects automatically.
Solution Approach 2:
The patent changes the electrical parameters within the connector by introducing an active circuit that can actively adjust impedance, signal level, and frequency characteristics. This parameter adjustment capability allows the connector to maintain optimal signal transmission characteristics for high-speed and wideband pulse signals without requiring precise physical manufacturing parameters. The active circuit dynamically optimizes electrical parameters to compensate for variations in component mounting and circuit implementation.
3Reliability
If a connector is designed to account for mutual influences of input and output circuits, then performance requirements can be met, but the design requires specialized technical know-how and the performance varies depending on designer expertise
Solution Approach 1:
The active circuit within the connector acts as a mediator that automatically handles the complex electrical interactions between input and output circuits. This intermediary element provides built-in isolation and impedance matching, eliminating the need for designers to manually calculate and compensate for mutual influences. As a result, consistent high performance can be achieved without requiring specialized technical know-how, making the design process easier and more accessible to ordinary engineers.
Solution Approach 2:
The connector with an active circuit performs self-service by automatically adapting to different external circuit conditions. The active circuit continuously maintains optimal electrical characteristics regardless of the specific external circuits connected, eliminating the need for designer intervention or specialized knowledge. This self-adjusting capability ensures consistent performance across different applications and reduces the variability that normally depends on designer expertise.

AI summary
An active connector is provided that allows for simple designing of devices for high-speed wideband pulse signal transmission without specialized technical know-how in the use of connectors. A connector base has a first connection terminal and a second connection terminal, and houses a first matching circuit, a second matching circuit, and a buffer circuit. The first connection terminal and the second connection terminal can be used as an internal port electrically coupled to a device circuit and an external port electrically coupled to a transmission line, respectively. An input signal inputted into the first connection terminal is supplied to the first matching circuit. The second matching circuit supplies an output signal to the second connection terminal. A buffer circuit between the first matching circuit and the second matching circuit inhibits mutual influences between the input signal and the output signal.
