Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID technology is used for recognizing optical connector connection, then recognition accuracy is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent extracts the wireless communication functionality from the optical adapter and places it in a separate IC tag attached to the optical connector. This allows the optical adapter to remain simple while still enabling automatic recognition through the IC tag's unique ID stored in non-volatile memory.
Solution Approach 2:
The patent uses a low-cost IC tag with non-volatile memory instead of expensive RFID readers. The IC tag is inexpensive, can be mass-produced, and maintains its functionality without requiring complex wireless communication hardware in the optical adapter.
2Measurement precision
If RFID technology is used for recognizing optical connector connection, then recognition accuracy is improved, but power consumption increases
Solution Approach 1:
The IC tag in the optical connector automatically provides its unique ID when connected to the optical adapter without requiring active wireless communication. The non-volatile memory retains the ID permanently, eliminating the need for continuous power consumption in the connector side.
Solution Approach 2:
The patent replaces power-intensive RFID technology with a low-power IC tag solution. The IC tag uses minimal power only during the brief connection detection process, significantly reducing overall power consumption compared to continuous RFID operation.
3Device complexity
If manual recognition method is used, then device complexity is reduced, but recognition accuracy and productivity deteriorate
Solution Approach 1:
The patent pre-assigns unique IDs to optical connectors and stores them in non-volatile memory within IC tags attached to the connectors. This preliminary action enables automatic recognition when connectors are installed, eliminating manual identification processes and accelerating service delivery.
Solution Approach 2:
The patent replaces manual mechanical identification processes with an automated electrical recognition system. When an optical connector is plugged into an optical adapter, the system automatically reads the IC tag ID through electrical contact, substituting human eyes and hands with an automated detection mechanism.
