Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If remote centralized control is used for switching apparatus, then device complexity is reduced, but reliability deteriorates due to susceptibility to electromagnetic disturbances and insufficient computing power
Solution Approach 1:
The patent divides the centralized control system into distributed local control units, with each switching apparatus having its own controller that can independently make control decisions. This segmentation allows the system to maintain simplicity while improving reliability through local autonomy and reduced dependency on remote centralized control.
2Reliability
If optical fiber connections are implemented for communication between switching apparatus, then reliability improves by reducing electromagnetic disturbance susceptibility, but device complexity increases due to additional communication infrastructure
Solution Approach 1:
The patent introduces optical fiber as an intermediary communication medium between switching apparatus and remote control systems. This optical intermediary provides immune communication against electromagnetic disturbances while maintaining system architecture simplicity through standardized communication interfaces and protocols.
3Power
If local control with optical ports is implemented, then computing power and real-time control capability increase, but device complexity increases due to additional controllers and optical communication interfaces
Solution Approach 1:
The patent implements dynamic control capability where controllers can operate autonomously in real-time when needed, while also being capable of remote centralized control when conditions permit. This dynamic control architecture provides sufficient computing power for real-time decisions while managing complexity through adaptive operational modes.
