Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric connection ports and pins are used to detect optical fiber jumper connection status, then connection detection can be performed, but electromagnetic interference and sparking occur leading to unsafe detection
Solution Approach 1:
The patent replaces the electrical detection system with an optical detection system. Specifically, it uses optical fibers to transmit detection signals and optical modules to convert between optical and electrical signals. The detection signal is transmitted through the optical fiber jumper being tested, eliminating direct electrical connections between detection devices and the jumper, thereby avoiding electromagnetic interference and sparking hazards.
Solution Approach 2:
The patent introduces optical modules as intermediary devices that convert electrical signals to optical signals for transmission through the optical fiber jumper. This intermediary optical transmission layer isolates the detection system from electromagnetic interference while maintaining detection functionality. The optical module acts as a buffer that converts between electrical and optical domains safely.
2Adaptability or versatility
If multiple optical fiber jumpers are present on ODF, then connection distribution is achieved, but electromagnetic field coupling causes interference between jumpers
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission for detection purposes. By using optical fibers to carry detection signals through each jumper, the system eliminates electromagnetic field coupling between adjacent jumpers on the ODF. Optical signals do not generate electromagnetic interference, allowing multiple jumpers to operate independently without mutual interference.
3Ease of operation
If manual operation and data recording are used for ODF maintenance, then operation flexibility is maintained, but human errors occur leading to incorrect connection records
Solution Approach 1:
The patent implements automatic detection and feedback mechanisms that continuously monitor the actual connection status of optical fiber jumpers. The detection system automatically compares the detected status with the recorded data in the database, and when discrepancies are found, it generates alarm information. This feedback loop ensures data accuracy without requiring manual verification, eliminating human error while maintaining operational flexibility.
Solution Approach 2:
The system performs self-verification by automatically detecting connection status and comparing it with recorded data without human intervention. The detection apparatus autonomously identifies mismatches between actual connections and database records, generating alerts for correction. This self-service capability maintains manual operation flexibility while ensuring data accuracy through automated verification.
