Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple laser beams of different wavelengths are transmitted through optical fibers, then the data transmission capacity is improved, but the uniform distribution of laser beams to multiple output ports becomes difficult to achieve
Solution Approach 1:
The optical marshalling module segments the multi-wavelength laser beams into separate wavelength channels, with each channel being independently directed to output ports. This segmentation allows each wavelength to be uniformly distributed while maintaining overall high data transmission capacity through parallel wavelength division multiplexing.
Solution Approach 2:
The patent introduces an optical marshalling module as an intermediary component between the laser source and output ports. This module contains wavelength-selective elements that act as mediators to sort and distribute different wavelengths uniformly across multiple output ports, resolving the distribution uniformity problem while preserving high transmission capacity.
2Volume of moving object
If the form factor of laser light sources is minimized, then the device size is reduced, but the efficiency of multi-wavelength beam distribution is compromised
Solution Approach 1:
The patent merges the optical marshalling functionality with the laser source assembly into an integrated laser module. By combining these functions in a compact configuration, the module achieves minimal form factor while maintaining efficient multi-wavelength beam distribution through integrated optical pathways and wavelength-selective elements.
Solution Approach 2:
The optical marshalling module is designed with multi-functional capabilities, serving both as a wavelength separation device and a beam distribution network. This universal design allows the compact module to handle multiple wavelengths efficiently while maintaining small form factor, as the same structural elements perform multiple optical functions.
3Use of energy by moving object
If energy consumption is reduced in laser light sources, then power efficiency is improved, but the reliability of laser light sources for optical data communication is compromised
Solution Approach 1:
The optical amplifying module provides continuous optical gain across all wavelength channels simultaneously, ensuring that low-power laser sources can maintain reliable signal levels throughout the communication system. The continuous amplification action compensates for the lower input power while maintaining signal integrity and system reliability.
Solution Approach 2:
The optical amplifying module is designed to automatically adjust its gain characteristics based on the input signal levels from the low-power laser source. This self-regulating behavior ensures that the system maintains optimal performance and reliability without requiring external power management intervention, allowing energy-efficient operation while preserving reliability.
