Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional copper telephone systems are used, then communication can be established, but the system becomes vulnerable to electrical interference and requires external power at each location
Solution Approach 1:
The patent replaces electrical signal transmission through copper cables with optical signal transmission through fiber optic cables. This substitution eliminates susceptibility to electrical interference and removes the need for electrical power at remote communication points, as the optical system is powered centrally at the audio control center.
Solution Approach 2:
The patent introduces optical fiber as an intermediary medium to replace direct electrical connection. The optical fiber transmits communication signals without requiring electrical power at the remote end, and the system uses an optical-to-electrical converter at the centralized power source to bridge the optical and electrical domains.
2Reliability
If back-up power sources are installed at multiple locations, then communication reliability during power failures is improved, but installation and maintenance costs increase
Solution Approach 1:
The patent consolidates power requirements into a single centralized location (the audio control center) rather than distributing power sources across multiple remote locations. This merging of power infrastructure reduces the total number of power sources needed, thereby lowering installation and maintenance costs while maintaining communication reliability during power failures.
3Object-affected harmful factors
If fiber optic cables are used for optical transmission, then immunity to electrical interference is achieved, but the system requires optical-to-electrical conversion components
Solution Approach 1:
The patent uses optical fiber as an intermediary transmission medium that is immune to electrical interference. While this requires optical-to-electrical conversion components at the centralized controller, it eliminates the need for electrical isolation and shielding that would be required in purely electrical systems, and allows for centralized power supply which simplifies the overall power infrastructure.
