Solution Overview

Problem

Conventional supervised clustering and anomaly detection models are ineffective in dynamic environments with changing conditions, leading to misidentification of input data as anomalous and requiring lengthy retraining periods, making them unsuitable for short-duration applications and resource-intensive.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional supervised clustering models are used for anomaly detection, then the models can categorize input data into clusters, but the models require long retraining periods and cannot adapt to dynamic environments with changing conditions

Engineering Contradiction:
Improveadaptability to dynamic environmentsVSAvoidretraining period
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements dynamic model adaptation by continuously updating the clustering model with newly arrived data points in real-time, rather than requiring periodic batch retraining. The model evolves adaptively as environmental conditions change, maintaining accuracy without long retraining periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The anomaly detection system performs self-updating by automatically incorporating new data points into the clustering model without external intervention. The model serves itself by continuously learning from incoming data, eliminating the need for manual retraining cycles.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If conventional supervised clustering models are deployed in new environments, then the models can perform anomaly detection, but the models are unable to provide accurate predictions when redeployed from one environment to another

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidprediction accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary adaptation by quickly learning the characteristics of a new environment through initial data processing before full deployment. This preliminary learning phase enables the model to adjust to environmental specifics rapidly, ensuring accurate predictions from the start of operations in the new environment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system adapts to different environments by dynamically adjusting model parameters based on the statistical characteristics of incoming data from each specific environment. This parameter adaptation allows the same model architecture to maintain high prediction accuracy across diverse operating conditions.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If conventional anomaly detection models are used in dynamic environments, then the models can detect anomalies, but the models mistake evolving environmental conditions for anomalous conditions resulting in hyper-classification

Engineering Contradiction:
Improveanomaly detection accuracyVSAvoidresponse to evolving conditions
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system implements continuous feedback loops where the clustering model is constantly updated with new data points, allowing it to distinguish between normal environmental evolution and true anomalies. The feedback mechanism enables the model to learn what constitutes normal variation in dynamic conditions, reducing false positive classifications.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If conventional supervised clustering models are retrained frequently, then the models can adapt to changing environments, but the retraining consumes greater computing resources making it economically ineffective

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidcomputational resource consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

Instead of performing complete model retraining, the system applies partial updates by incorporating only the necessary adjustments from new data points. This partial action approach maintains adaptability while significantly reducing computational resource consumption compared to full retraining cycles.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A sampling device receives, from a transducer computing device located within a predefined proximity to an equipment in an operating environment, a vibration sample from the operating environment. The sampling device predicts, using a model, (1) an anomalous designation or a non-anomalous designation for the vibration sample and (2) a cluster assignment, to a particular cluster of a set of clusters, for the vibration sample when the model predicts the non-anomalous designation for the vibration sample. The sampling device transmits, to a computing device of the equipment, instructions to cease to perform the operation responsive to predicting the anomalous designation.
