Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advanced optical access communication systems are deployed to meet increasing bandwidth demand, then connectivity and service capability are improved, but deployment cost and operational cost increase significantly
Solution Approach 1:
The patent combines multiple functions (routing, switching, wavelength management) into a single integrated optical access network architecture, eliminating the need for separate middle equipment like routers and switches. This consolidation reduces deployment complexity and cost while maintaining advanced bandwidth capabilities through the unified optical infrastructure.
Solution Approach 2:
The optical access network is designed with multi-functional capabilities, where a single system provides both high-speed data communication and wavelength division multiplexing services. The network can dynamically allocate wavelengths and bandwidth to different users and services, making the infrastructure universally applicable to various bandwidth requirements without requiring additional specialized equipment.
2Length of stationary object
If middle equipment like routers and switches are added to extend network reach, then connectivity coverage is improved, but capital cost and operational cost increase
Solution Approach 1:
The patent extracts and removes middle equipment (routers, switches) from the optical access network architecture. By eliminating these intermediate components, the network achieves extended reach through direct optical connections while reducing capital costs associated with purchasing and deploying additional networking hardware.
Solution Approach 2:
The network extends its reach by transitioning to the optical domain, using light-based transmission instead of electrical signals through traditional routers and switches. This dimensional change to optical communication enables longer transmission distances and greater network reach without requiring intermediate electronic switching equipment.
3Device complexity
If traditional optical access networks are used, then infrastructure cost is reduced, but service flexibility and on-demand capability are limited
Solution Approach 1:
The optical access network implements dynamic service allocation capabilities, where bandwidth, wavelengths, and network resources can be reallocated in real-time based on user demands and service requirements. This dynamic control enables the system to provide on-demand services while maintaining a cost-effective infrastructure, as resources are optimized and adjusted continuously rather than being statically configured.
Solution Approach 2:
The network utilizes wavelength division multiplexing to provide service flexibility by changing the optical parameter of wavelength. Different services and users can be assigned to different wavelengths, allowing the infrastructure to support multiple services simultaneously with a single physical network, thereby enhancing service flexibility without requiring additional infrastructure investment.
