Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If metal wires are used for signal transmission, then electrical connection is established, but power consumption increases and cost increases
Solution Approach 1:
The patent replaces electrical signal transmission through metal wires with optical signal transmission through optical fibers. The audio signal is converted to optical signals that travel through optical fiber cables, eliminating the need for expensive low-power metal wire connections while reducing power consumption and system cost.
Solution Approach 2:
The patent changes the transmission medium from electrical conductors (metal wires) to optical conductors (optical fibers). This fundamental parameter change in the transmission medium allows signal transmission with lower power consumption and reduced cost while maintaining signal integrity.
2Reliability
If metal wires are used for signal transmission, then signal transmission is achieved, but signal loss increases and transmission distance is limited
Solution Approach 1:
The patent substitutes optical fiber transmission for metal wire transmission. Optical fibers exhibit significantly lower signal attenuation compared to metal wires, enabling longer transmission distances without signal degradation. The audio signal is converted to optical form, transmitted through the optical fiber, and then converted back to electrical form at the destination.
3Loss of energy
If expensive metal wires are used to reduce power consumption, then power consumption is reduced, but system cost increases
Solution Approach 1:
The patent replaces the expensive metal wire-based electrical transmission system with an optical fiber-based transmission system. This substitution achieves lower power consumption while simultaneously reducing system cost, as optical fiber infrastructure is more cost-effective than high-performance metal wire connections required for low-power electrical transmission.
