Engineering Contradiction Analysis
1Measurement precision
If in-person review is used to diagnose signal disruptions, then accurate diagnosis can be achieved, but time consumption and cost increase significantly
Solution Approach 1:
The system enables self-service by implementing automatic monitoring and diagnosis capabilities at the subscriber facility. The integrated circuit continuously monitors signal parameters and automatically identifies disruptions without requiring manual intervention, thus achieving accurate diagnosis while eliminating time consumption associated with in-person reviews
Solution Approach 2:
An intermediary monitoring system is introduced between the signal source and the service provider. This intermediate circuit captures and analyzes signal characteristics, serving as a mediator that provides diagnostic information remotely, thereby maintaining diagnosis accuracy while reducing the need for physical presence
2Measurement precision
If in-person review is used to diagnose signal disruptions, then comprehensive signal analysis can be performed, but operational efficiency decreases
Solution Approach 1:
The mechanical system of in-person physical review is replaced with an electronic monitoring system. The integrated circuit automatically performs signal analysis functions that previously required manual intervention, maintaining comprehensive analysis capability while dramatically improving operational efficiency through automation
Solution Approach 2:
The monitoring system performs self-service by automatically capturing, analyzing, and reporting signal disruptions without external intervention. This autonomous operation maintains comprehensive signal analysis while improving productivity by eliminating the need for service provider deployment
3Productivity
If integrated circuits are implemented for remote monitoring, then time and cost efficiency improve, but device complexity increases
Solution Approach 1:
Multiple monitoring functions are merged into a single integrated circuit. The circuit combines signal capture, dynamic range adjustment, spectral analysis, and disruption detection capabilities in one unified device, thereby improving operational efficiency while managing complexity through functional integration rather than multiplication of separate components
Solution Approach 2:
The integrated circuit is designed with multi-functionality to perform various monitoring tasks. It can capture broadband signals, adjust dynamic ranges, analyze spectra, and detect multiple types of disruptions using the same hardware platform, thus improving productivity without proportionally increasing device complexity
