Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeater chips are arranged asymmetrically in USB-C connection cable, then signal compensation works in forward direction, but signal compensation fails in reverse direction without program assistance
Solution Approach 1:
The patent applies asymmetry in reverse - it uses symmetric arrangement of repeater chips to achieve bi-directional functionality. Each connection port has a repeater chip with identical circuit structure, allowing both ports to independently perform signal compensation in either direction, thus resolving the contradiction between forward-direction reliability and reverse-direction adaptability
Solution Approach 2:
Each repeater chip is designed with universal functionality to handle both forward and reverse signal transmission. The chips can independently adjust signals in any direction without requiring program assistance, making the cable truly bi-directional and eliminating the limitation of asymmetric designs
2Reliability
If program assistance is used for signal compensation in reverse direction, then signal attenuation can be compensated, but device complexity and energy consumption increase
Solution Approach 1:
Each repeater chip is equipped with independent adjustment circuits that enable self-service signal compensation. The chips can autonomously adjust gain and equalization parameters for reverse direction signals without external program control, reducing device complexity and energy consumption while maintaining compensation effectiveness
3Ease of manufacture
If asymmetric repeater chip arrangement is used, then manufacturing is simpler, but bi-directional signal adjustment capability is lost
Solution Approach 1:
The patent uses symmetric design where both connection ports have identical repeater chip arrangements. This symmetry simplifies manufacturing by allowing identical assembly processes for both ends of the cable, while simultaneously enabling full bi-directional signal adjustment capability
Solution Approach 2:
The repeater chips can dynamically change their adjustment parameters based on signal direction. By modifying gain and equalization parameters, the chips adapt to either forward or reverse signal transmission, achieving bi-directional capability without complex asymmetric hardware arrangements

AI summary
A bi-directional signal transmission connection cable is disclosed. The bi-directional signal transmission connection cable can be connected between a first and a second electronic device. The bi-directional signal transmission connection cable includes a first connection port, a second connection port, a first repeater chip, a second repeater chip and a plurality of transmission wires. The first and the second repeater chips are symmetrically disposed in the first and the second connection ports. The first repeater chip has a first set of adjustment parameters, and the second repeater chip has a second set of adjustment parameters. Thus, when a signal is transmitted between the first and the second electronic devices via the first connection port, the second connection port, and the plurality of transmission wires, the signal is adjusted by the first set of adjustment parameters and the second set of adjustment parameters.
