Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple optical signals with different wavelengths are transmitted through a single optical fiber, then data transmission capacity is improved, but signal separation and processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the optical signal processing into multiple stages using wavelength division demultiplexers. These demultiplexers separate different wavelength signals at different levels, transforming a complex multi-wavelength separation task into multiple simpler separation stages, thereby resolving the contradiction between handling multiple wavelengths and maintaining processing simplicity
Solution Approach 2:
The patent introduces wavelength division demultiplexers as intermediary devices between the optical fiber input and the light receiving components. These intermediaries perform wavelength-based signal separation, enabling the system to handle multiple wavelengths without directly complicating the final signal reception and processing stage
2Speed
If transmission rate is continuously increased to support new services, then communication capability is improved, but signal quality and interference resistance deteriorate
Solution Approach 1:
The patent segments the optical signal spectrum into multiple wavelength channels using wavelength division demultiplexers. This segmentation allows each wavelength channel to be processed independently at optimized data rates, preventing the cumulative interference that would occur with a single high-rate channel while maintaining overall high transmission capacity
Solution Approach 2:
The patent changes the transmission parameter from a single high-rate channel to multiple wavelength channels, each potentially operating at optimized rates. This parameter transformation enables the system to achieve high overall transmission rates while maintaining signal quality through wavelength-based isolation and independent processing
