Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated hardware is prepared for each service, then service requirements can be met, but capital investment and operational costs increase significantly
Solution Approach 1:
The patent implements a universal optical signal processing platform that can handle multiple services (PTP, PtMP, MFH) through a single shared infrastructure. The optical main signal processing node apparatus performs wavelength conversion and signal processing for different services using the same hardware resources, eliminating the need for separate dedicated hardware for each service type.
Solution Approach 2:
The patent merges multiple service processing functions into a single integrated optical network node. By combining wavelength conversion units, optical signal processing units, and path switching units into one shared platform, the system achieves resource consolidation and reduces the total hardware quantity required while maintaining the ability to support diverse service requirements.
2Adaptability or versatility
If dedicated LSI is prepared for each service, then service-specific processing is optimized, but management becomes cumbersome and capital investment increases
Solution Approach 1:
The patent employs dynamic path switching capability where the optical main signal processing node can flexibly route different wavelengths to appropriate processing paths based on real-time service requirements. The path switch unit dynamically connects or disconnects wavelength paths, allowing the system to adapt to changing service demands without requiring separate static dedicated hardware for each service.
Solution Approach 2:
A single optical main signal processing node performs multiple functions including wavelength conversion, optical signal processing, and path switching for different services. This universal platform replaces the need for multiple separate LSIs, simplifying management while maintaining service-specific processing capabilities through software-controlled functionality.
3Adaptability or versatility
If LSIs are reproduced when service requirements change, then service adaptability is achieved, but production costs and time increase
Solution Approach 1:
The system uses dynamic reconfiguration through path switching and wavelength conversion rather than physical LSI reproduction. When service requirements change, the optical main signal processing node dynamically adjusts its configuration and routing paths, eliminating the need for time-consuming LSI manufacturing and deployment cycles.
Solution Approach 2:
The patent changes operational parameters such as wavelength allocation and path routing configurations to adapt to new service requirements. Instead of reproducing LSIs, the system reconfigures existing hardware parameters and connections, achieving service adaptability instantly without production lead times.
4Quantity of substance
If multiple services are accommodated in shared optical network, then hardware resources are reduced, but network reliability may be compromised
Solution Approach 1:
The patent segments the optical signal processing into distinct functional units: wavelength conversion units for each service type, optical signal processing units, and path switching units. This segmentation allows independent management and processing of different services within the shared network, isolating failures and maintaining reliability while using shared hardware resources.
Solution Approach 2:
The optical main signal processing node acts as an intermediary between different service types and the shared optical infrastructure. It performs wavelength conversion and signal processing to ensure that different services can coexist in the shared network without interfering with each other, thereby maintaining network reliability through controlled signal management.
