Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring methods are used to supply power to nodes, then power supply reliability is improved, but installation flexibility and adaptability to various locations deteriorate
Solution Approach 1:
The patent combines power supply function and communication function into a single optical fiber infrastructure. By merging the power transmission capability with the existing communication fiber network, the system achieves both reliable power delivery and flexible installation without requiring separate wiring for power supply.
Solution Approach 2:
The optical fiber is designed to serve multiple functions simultaneously: it acts as both a communication channel and a power transmission medium. This multi-functionality allows the same infrastructure to support both data transmission and power supply, eliminating the need for dedicated power wiring and enabling installation in locations where traditional power delivery would be difficult.
2Reliability
If separate power wiring is installed for each node, then power supply stability is improved, but system complexity and installation difficulty increase
Solution Approach 1:
The patent merges multiple functions (power supply and communication) into a single integrated system using optical fibers. This reduces the overall system complexity by eliminating redundant infrastructure and simplifying the number of components that need to be installed and maintained.
Solution Approach 2:
By designing the optical fiber system to perform both power transmission and communication functions, the patent reduces device complexity. Instead of having separate power wiring and communication cables, a single universal medium handles both tasks, reducing installation complexity and system overhead.
3Adaptability or versatility
If optical power supply method is used, then installation flexibility and adaptability are improved, but power transmission efficiency may deteriorate
Solution Approach 1:
The patent segments the optical power into multiple wavelengths or channels within the optical fiber. By dividing the power transmission into different spectral components, the system can efficiently transmit power while maintaining the flexibility of optical fiber deployment. This segmentation allows for optimized power delivery without compromising installation adaptability.
