Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an oscilloscope is connected to the buffered output of the sensor to evaluate intermittent problems, then the ability to capture and analyze phase sensor signals during anomalies is improved, but the system complexity and need for additional equipment increases
Solution Approach 1:
The patent combines the phase sensor signal input, analog-to-digital converter, and storage system into a single integrated monitoring system. The storage system is directly coupled to receive and save digital phase signals during anomalies, eliminating the need for separate oscilloscope equipment and reducing overall system complexity while maintaining diagnostic capabilities
Solution Approach 2:
The monitoring system performs multiple functions: it continuously monitors phase sensor signals, detects anomalies, captures digital phase signals during anomalies, and stores them for later analysis. This multi-functional approach replaces the need for separate specialized equipment like oscilloscopes, reducing device complexity while improving measurement precision
2Reliability
If an oscilloscope is left connected to monitor for intermittent problems, then the ability to capture reoccurrences is improved, but the loss of time for manual observation and setup increases
Solution Approach 1:
The storage system is pre-configured to automatically capture and save digital phase signals when anomalies are detected. This preliminary setup eliminates the need for manual oscilloscope connection and observation during anomaly reoccurrences, reducing time loss while maintaining reliable detection capabilities
Solution Approach 2:
The monitoring system automatically detects anomalies and triggers signal capture without requiring manual intervention. The system serves itself by continuously monitoring, automatically saving signals during anomalies, and making data available for later analysis, eliminating the need for continuous manual observation
3Difficulty of detecting and measuring
If manual observation with oscilloscope is used for troubleshooting, then diagnostic capability is improved, but the ease of operation and accessibility for hazardous locations worsens
Solution Approach 1:
The patent extracts the signal capture and storage functionality from the hazardous monitoring environment by implementing automatic digital signal saving during anomalies. The captured data can be analyzed remotely without requiring operators to physically access hazardous locations, improving ease of operation and operator safety while maintaining troubleshooting capability
Solution Approach 2:
The storage system acts as an intermediary between the phase sensor and the analyst. It automatically captures, saves, and preserves phase sensor signals during anomalies, allowing remote analysis without requiring direct operator presence in hazardous environments, thus improving safety and ease of operation
