Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operators are used for predictive maintenance, then device complexity is reduced, but productivity and reliability deteriorate due to inefficiency in detecting poor operating conditions
Solution Approach 1:
The system enables self-service through automated sensor hubs that continuously monitor equipment conditions and trigger maintenance alerts without human intervention. The sensor hubs autonomously detect poor operating conditions, classify faults, and notify operators, replacing manual inspection with self-diagnostic capabilities.
Solution Approach 2:
Manual inspection methods are replaced with electronic sensor-based monitoring systems. The patent substitutes human operators with automated sensor hubs equipped with vibration, temperature, and pressure sensors that continuously collect and analyze equipment data, providing more reliable and consistent detection.
2Productivity
If real-time monitoring is implemented, then productivity is improved through continuous operation, but loss of time increases due to potential downtime for data collection and analysis
Solution Approach 1:
The system performs preliminary action by continuously collecting and analyzing equipment data before actual failure occurs. Sensor hubs monitor vibration patterns, temperature changes, and other parameters in real-time, detecting early signs of degradation and triggering preventive maintenance alerts, allowing maintenance to be performed during planned downtime rather than unexpected failures.
Solution Approach 2:
The system implements feedback loops where sensor data is continuously analyzed and compared against baseline conditions. When deviations indicate poor operating conditions, the system provides feedback through alerts and notifications, enabling operators to take corrective action. The system learns from historical data to improve future predictions and reduce false alarms.
3Measurement precision
If comprehensive sensor data collection is performed, then measurement precision is improved, but use of energy increases due to continuous monitoring and data transmission
Solution Approach 1:
The system applies partial action by selectively monitoring only the most critical parameters and equipment components. Sensor hubs prioritize data collection based on equipment importance, operational conditions, and risk levels. The system adjusts monitoring intensity dynamically, collecting comprehensive data when anomalies are detected and reducing monitoring intensity during normal operation to conserve energy.
