Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional predictive maintenance systems are used for vibrating screening equipment, then maintenance activities can be performed, but the systems perform unnecessary maintenance and fail to anticipate equipment failures accurately
Solution Approach 1:
The patent replaces conventional mechanical monitoring systems with an AI-based predictive maintenance system that uses machine learning algorithms to analyze vibration data. The system substitutes traditional rule-based maintenance scheduling with intelligent algorithms that can accurately predict equipment failures by learning patterns from historical vibration data, thereby reducing unnecessary maintenance while improving failure anticipation accuracy.
Solution Approach 2:
The system implements continuous feedback loops where vibration sensors constantly monitor equipment condition, feed data to the AI algorithm, which then adjusts maintenance predictions in real-time. This feedback mechanism enables the system to learn from actual equipment behavior and improve its failure prediction accuracy over time, reducing both unexpected downtime and unnecessary maintenance interventions.
2Measurement precision
If AI-based predictive maintenance system with multiple sensors is implemented, then prediction accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the monitoring system into modular components: vibration sensors placed at specific locations on the screening equipment, edge computing devices for local data processing, and cloud-based AI algorithms for predictive analytics. This segmentation allows the system to achieve high measurement precision through distributed sensing while managing complexity through modular architecture that can be deployed incrementally.
Solution Approach 2:
The system introduces edge computing devices as intermediaries between the physical sensors and the cloud-based AI algorithms. These edge devices pre-process vibration data locally, filtering and aggregating information before transmission to the cloud, thereby reducing the computational burden on the central system and simplifying the overall architecture while maintaining high measurement precision.
3Loss of information
If real-time data collection from multiple sensors is performed, then diagnostic accuracy is enhanced, but data processing requirements and computational load increase
Solution Approach 1:
The system extracts only the most relevant features from the raw vibration data using signal processing techniques at the edge devices. Instead of transmitting and processing all raw sensor data, the system identifies and extracts key vibration characteristics (frequency, amplitude, spectral features) that are most indicative of equipment condition, thereby reducing computational energy consumption while maintaining complete functional information for accurate diagnostics.
