Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static optimization of transmission modules is performed during installation, then equipment deployment is simplified, but capacity utilization becomes inefficient and cannot adapt to evolving user needs
Solution Approach 1:
The patent implements dynamic connection rearrangement that allows the optical access network to adapt its topology after installation. The system continuously monitors capacity utilization and automatically reconfigures connections between user modules and transmission modules to optimize resource allocation, transforming the static network into a dynamic one that responds to changing user demands.
Solution Approach 2:
The system employs feedback mechanisms by monitoring capacity utilization metrics and using this information to trigger connection rearrangement operations. The management platform receives status information from the network, evaluates whether optimization is needed, and executes reconfiguration accordingly, creating a closed-loop control system that continuously improves capacity utilization.
2Adaptability or versatility
If more transmission modules are deployed to meet evolving user needs, then service capacity increases, but equipment costs and network complexity increase
Solution Approach 1:
The patent makes existing transmission modules multi-functional by enabling them to serve different user modules at different times through dynamic reconfiguration. A single transmission module can be dynamically assigned to different user groups based on demand, allowing the same hardware to fulfill multiple service roles without requiring additional dedicated equipment for each scenario.
Solution Approach 2:
The system changes the operational parameters of the network by dynamically adjusting connection topologies rather than changing physical hardware configurations. By modifying logical connection parameters and resource allocation settings, the network achieves adaptability and handles varying service capacities without adding physical equipment or increasing structural complexity.
3Ease of operation
If transmission module capacities are statically allocated during installation, then network configuration is simplified, but flexibility in network usage is reduced
Solution Approach 1:
The patent transforms static capacity allocation into dynamic capacity allocation where transmission module resources are continuously adjusted based on actual network conditions. The system maintains simple initial configuration but adds dynamic reconfiguration capabilities that automatically optimize resource distribution, achieving both ease of operation and flexibility through automated adaptation rather than complex manual configuration.
