Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optical signals are converted into electrical signals at network boundaries, then equipment sharing and economy are achieved, but transmission delay and bandwidth restrictions occur
Solution Approach 1:
The patent replaces the optical-to-electrical conversion mechanism with direct optical signal transmission through the network boundary. The optical transmission device enables light-based signals to pass directly from access network to metro network without electrical conversion, eliminating the delay inherent in mechanical conversion processes while maintaining equipment sharing capabilities.
Solution Approach 2:
The patent introduces an optical transmission device as an intermediary component that facilitates direct optical signal transmission between network segments. This intermediary device enables seamless optical signal passage through the boundary without requiring electrical conversion, thus resolving the contradiction between equipment sharing and transmission delay.
2Adaptability or versatility
If optical signals are converted into electrical signals, then electrical processing such as reproduction relay and wavelength conversion can be performed, but bandwidth efficiency deteriorates
Solution Approach 1:
The patent substitutes the electrical processing approach with optical-domain processing. By maintaining optical signals in their original form throughout the transmission and enabling direct optical transmission across boundaries, the system achieves bandwidth efficiency while still providing necessary processing capabilities through optical-based methods rather than electrical conversion.
3Speed
If light through function is implemented, then optical signal transfer across boundary is achieved, but electrical processing capability is lost
Solution Approach 1:
The patent maintains optical signal transfer speed by implementing direct light through transmission across network boundaries. The optical transmission device enables high-speed optical signal passage while integrating functionality to provide electrical processing capabilities when needed, thus resolving the contradiction between transfer speed and processing capability.
