Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If systematic elimination of potential causes is used to identify faulty optical transceivers, then fault identification can be performed, but the process becomes laborious and time-consuming
Solution Approach 1:
The patent applies preliminary action by monitoring optical transceiver parameters (current, power output, temperature) continuously before failure occurs. This allows predictive identification of failing transceivers through trend analysis, eliminating the need for time-consuming systematic elimination processes after network outages occur.
Solution Approach 2:
The patent implements feedback mechanisms by continuously collecting operational data from optical transceivers and comparing it against threshold values and historical patterns. This real-time feedback enables proactive detection of degradation trends, allowing failure prediction before actual network failures occur.
2Measurement precision
If troubleshooting is performed to identify faulty optical transceivers, then the source of network faults can be identified, but network functionality is compromised during the process
Solution Approach 1:
The patent enables preliminary identification of failing transceivers through continuous monitoring of operational parameters. By detecting degradation trends before actual failure, the system allows proactive replacement of transceivers during maintenance windows rather than reacting to network outages, thus maintaining network functionality during troubleshooting.
Solution Approach 2:
The patent implements self-service by enabling optical transceivers to self-diagnose and self-report their operational status through built-in monitoring capabilities. This eliminates the need for manual troubleshooting procedures that compromise network functionality, as the system automatically identifies and reports potential failures.
3Reliability
If optical network transceivers are monitored continuously, then failure prediction is possible, but additional monitoring infrastructure and resources are required
Solution Approach 1:
The patent applies self-service by implementing monitoring capabilities within the optical transceiver itself rather than requiring external monitoring infrastructure. The transceiver uses its own internal resources (processor, memory, sensors) to self-monitor parameters like current, power output, and temperature, eliminating the need for complex external monitoring systems.
Solution Approach 2:
The patent implements universality by designing a multi-functional monitoring system that handles multiple tasks within the transceiver: operational parameter collection, data analysis, threshold comparison, trend detection, and failure prediction. This consolidates what would traditionally require separate dedicated systems into a single integrated component.
Data Source
AI summary
The amount of current provided to a laser diode of an optical network transceiver device is monitored, the amount of current reaching a threshold limit is detected, and the power output of the optical network transceiver device is monitored. Based at least in part on the detection that the amount of current has reached the threshold limit and the monitored power output of the optical network transceiver device, a likelihood of failure of the optical network transceiver device is predicted.
