Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If monitoring is performed based on pre-identified monitoring targets, then the monitoring system can focus resources on specific targets, but the system cannot properly respond to unforeseen events or newly occurring events
Solution Approach 1:
The optical fiber is pre-deployed in the monitoring area to enable immediate detection of any event, regardless of whether it was anticipated. The system performs preliminary preparation by having the sensing infrastructure in place before events occur, allowing rapid response to both expected and unexpected situations
Solution Approach 2:
The optical fiber acts as an intermediary sensing medium that detects vibrations and events throughout the monitoring area. This intermediary enables the system to capture information about unforeseen events and transmit it to the identification unit, which then determines appropriate monitoring responses
2Adaptability or versatility
If optical fiber is deployed throughout the monitoring area for comprehensive event detection, then the system can detect unforeseen events, but the time required to identify and respond to events increases
Solution Approach 1:
The system replaces manual or mechanical search and identification methods with automated optical sensing and digital signal processing. The optical fiber network automatically detects events and the identification unit rapidly processes the data to determine event locations and types, significantly reducing response time compared to traditional mechanical monitoring approaches
Solution Approach 2:
The optical fiber sensing system operates autonomously to detect and identify events without requiring continuous human intervention. The system self-monitors the entire area, automatically processes detected signals to identify events, and generates alerts, thereby reducing the time loss associated with manual event detection and response coordination
