Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fiber ring network with dual-direction transmission is implemented, then system reliability is improved through failover protection, but device complexity increases due to multiple root ports and transmission paths
Solution Approach 1:
The system segments the transmission network into primary and secondary ring root ports, each handling specific transmission directions. This segmentation allows independent failure isolation and failover protection while maintaining manageable complexity through structured division of transmission paths.
Solution Approach 2:
The patent implements beforehand cushioning by establishing backup transmission paths through secondary ring root ports before failures occur. When a failure is detected in the primary transmission path, the system seamlessly switches to the pre-configured secondary path, providing failover protection without requiring complex real-time decision-making.
2Speed
If dynamic burst-to-broadcast transmission scheme is implemented, then communication speed is improved, but device complexity increases due to multiple transmission root ports and networks
Solution Approach 1:
The system implements dynamic transmission schemes where the controller can switch between burst transmission mode (for high-speed data transfer) and broadcast transmission mode (for control messages). This dynamic adaptability optimizes communication speed for different message types while the standardized multi-port architecture keeps the complexity manageable through consistent interface design.
Solution Approach 2:
The transmission root ports and optical fiber ring networks are designed with multi-functionality, serving both burst transmission and broadcast transmission purposes. This universality allows a single infrastructure to support multiple transmission modes, achieving high communication speed without proportionally increasing device complexity.
3Reliability
If multi-core architecture with failover mechanism is implemented, then system reliability is improved, but ease of operation deteriorates due to complex system integration
Solution Approach 1:
The failover mechanism incorporates continuous feedback monitoring of transmission path health status. When failures are detected, the system automatically triggers failover to backup paths. This feedback-driven approach improves reliability while simplifying operation by eliminating the need for manual intervention in failure scenarios.
Solution Approach 2:
The multi-core architecture with failover mechanism implements self-service capabilities where the system automatically detects failures, selects alternative transmission paths, and maintains operation without human intervention. This automation improves reliability while keeping the system easy to operate by removing complex manual configuration and troubleshooting requirements.
