Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring and maintenance solutions for industrial machines are inadequate in predicting machine failures in real-time, as they rely on static prediction models that become outdated and require ongoing maintenance, often identifying failures only after downtime begins, leading to significant production losses and costs.
Innovation Solution
An online machine learning-based method and system that receives sensor data from industrial machines, generates indicative data features, applies unsupervised machine failure detection processes to detect and predict failures, and continuously updates the prediction models using new data, enabling proactive maintenance and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static prediction models are used to detect machine failures, then the detection mechanism is simple to implement, but the models become outdated and require ongoing maintenance, reducing reliability over time
Solution Approach 1:
The patent transitions from static prediction models to dynamic online learning models that continuously adapt to changing machine conditions. The system updates prediction models in real-time as new sensor data becomes available, ensuring the models remain current and accurate without requiring manual retraining or maintenance interventions.
Solution Approach 2:
The system implements feedback loops where detection results and new sensor data are continuously fed back into the prediction models. This feedback mechanism allows the models to learn from actual machine behavior and failure patterns, automatically improving their accuracy and adapting to evolving conditions without external intervention.
2Device complexity
If existing monitoring systems are used to identify failures, then the system structure is simple, but failures are identified only after or immediately before downtime begins, leading to significant production losses
Solution Approach 1:
The online learning prediction models enable preliminary detection of potential failures before they actually occur. By continuously analyzing sensor data and learning from patterns, the system can predict upcoming failures and trigger maintenance actions in advance, preventing downtime rather than merely detecting it after it has begun.
3Ease of operation
If static detection models are applied to dynamic machine data, then the implementation is straightforward, but the models become outdated and irrelevant as machine data changes, requiring ongoing maintenance
Solution Approach 1:
The system employs dynamic online learning models that continuously adapt to changing machine conditions. Rather than using fixed static models, the prediction algorithms evolve with the machine's operational characteristics, automatically adjusting to new patterns and conditions as they emerge from incoming sensor data.
Solution Approach 2:
The prediction models perform self-updating and self-improvement through continuous online learning. The system automatically adapts to changing conditions without requiring external maintenance or manual recalibration, effectively serving itself by continuously learning from new data and adjusting its prediction capabilities accordingly.

AI summary
Disclosed herein a method and machine monitoring system for predicting failures of industrial machines. The system is configured to receive sensor data related to a machine, such as large industrial machinery, and select indicative data features for machine failures. The system then applies an unsupervised machine failure detection process and a supervised machine failure prediction process to the selected indicative data feature. When new sensor data of the machine is received, a machine failure detection process is applied to the selected at least one indicative data feature that is associated with the new sensor data. This allows the disclosed system to determine whether at least one machine failure indicator was detected and if so, the machine failure is tagged. Then, the system updates the supervised machine failure prediction process with the new tagged machine failure indicators, such that the supervised machine failure prediction process is continuously updated and improved.
