Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If small cell deployment is pursued to provide additional mobile bandwidth, then bandwidth capability is improved, but network complexity and fault tolerance challenges increase
Solution Approach 1:
The patent segments the communication network into multiple independent communication links (primary and backup links) that can operate autonomously. Each link can be independently configured and managed, allowing the network to maintain bandwidth capability through multiple paths while reducing overall system complexity through modular design. The small cells are deployed as independent units with their own communication links, enabling selective activation based on fault conditions.
2Reliability
If multiple communication links are implemented for fault tolerance, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic link selection where the network automatically switches between primary and backup communication links based on real-time fault detection. The system dynamically adapts its configuration by monitoring link status and selecting appropriate paths, improving reliability without requiring complex manual management. The dynamic nature allows simple automated operation while maintaining high availability.
Solution Approach 2:
The patent incorporates feedback mechanisms where communication links continuously monitor their own status and provide information about faults or disturbances. This feedback enables automatic detection and response to failures, allowing the system to switch to backup links without complex intervention. The feedback-driven approach simplifies fault tolerance management by automating the monitoring and switching processes.
3Productivity
If guided wave propagation is used for data transmission, then transmission efficiency is improved, but detection of disturbances becomes more difficult
Solution Approach 1:
The patent introduces sensors as intermediary devices that detect disturbances in the guided wave propagation path. These sensors act as mediators between the transmission system and the control system, providing early warning of faults without interfering with the efficient guided wave data transmission. The sensors monitor parameters such as signal quality and environmental conditions, enabling proactive fault detection while maintaining high transmission efficiency.
