Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual testing methods are used for optical transceivers, then testing flexibility is maintained, but testing efficiency is low and troubleshooting time is excessive
Solution Approach 1:
The optical transceiver performs self-diagnosis by automatically executing troubleshooting techniques to identify BER issues. The system autonomously adjusts expert mode settings, executes diagnostic tests, and isolates problematic configurations without requiring manual intervention, thereby significantly reducing troubleshooting time while maintaining testing flexibility.
Solution Approach 2:
The system performs preliminary diagnostic actions by automatically executing a sequence of troubleshooting techniques before manual intervention is needed. The automated troubleshooting process proactively identifies and isolates BER issues, preventing time loss and improving testing efficiency by preparing diagnostic data in advance.
2Measurement precision
If expert mode settings are manually adjusted, then testing precision can be controlled, but the complexity of test configuration increases
Solution Approach 1:
The automated troubleshooting system incorporates feedback mechanisms that monitor BER performance and automatically adjust expert mode settings based on diagnostic results. The system receives feedback from diagnostic tests and dynamically modifies test configurations to optimize BER measurement accuracy, eliminating the need for complex manual configuration while maintaining precision.
Solution Approach 2:
The system automatically changes test parameters by adjusting expert mode settings according to diagnosed issues. The automated troubleshooting process modifies parameters such as test sequences, measurement conditions, and diagnostic configurations to optimize BER measurement accuracy, reducing configuration complexity while maintaining precision through algorithmic parameter optimization.
3Reliability
If comprehensive troubleshooting techniques are implemented, then diagnostic capability is improved, but the time required for testing increases
Solution Approach 1:
The comprehensive troubleshooting technique is segmented into a structured sequence of diagnostic steps. The system divides the troubleshooting process into discrete, manageable phases that automatically execute in order, improving diagnostic capability while controlling testing duration through systematic progression through predefined diagnostic segments.
Solution Approach 2:
The automated troubleshooting system maintains continuous diagnostic action by executing troubleshooting techniques without interruption. The system continuously monitors BER performance, executes diagnostic tests, and adjusts settings in an uninterrupted sequence, improving reliability through comprehensive diagnosis while minimizing idle time and optimizing total testing duration.
