Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for predicting the behavior of physical devices, such as motors or electronic components, are unreliable due to changes caused by external influences over time, leading to uncertainties and increased risks in decision-making regarding device maintenance, usage, and replacement.
Innovation Solution
A method using an electronic computing device to generate a reliable behavior prediction by adapting an initial model of the device's behavior based on recorded parameters, creating a behavioral model that learns alongside the device and simulates behavior under specified conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an initial model is used to predict device behavior, then predictions are accurate at the beginning of the device life cycle, but prediction accuracy deteriorates over time as the device behavior changes
Solution Approach 1:
The patent implements a dynamic behavioral model that continuously adapts to the device's changing behavior over time. The model is trained on historical data and updated as new data becomes available, allowing it to evolve alongside the device. This dynamic approach resolves the contradiction by making the prediction system flexible and responsive to temporal changes in device behavior, maintaining accuracy throughout the device's operational life cycle.
Solution Approach 2:
The system incorporates feedback mechanisms where actual device behavior data is continuously collected and used to retrain and refine the behavioral model. This closed-loop feedback ensures that the model learns from deviations between predicted and actual behavior, correcting its predictions over time. The feedback principle directly addresses the accuracy deterioration problem by enabling continuous model improvement based on real-world performance data.
2Reliability
If safety margins are increased to limit risks, then reliability of decision-making improves, but device utilization efficiency deteriorates due to premature maintenance or replacement
Solution Approach 1:
The patent changes the critical parameter from fixed safety margins to dynamic, data-driven confidence levels. Instead of using conservative fixed thresholds, the system calculates confidence levels based on the behavioral model's prediction accuracy and the specific context. This allows decision-making reliability to be maintained through quantitative assessment while avoiding unnecessary conservatism, thereby improving device utilization efficiency by preventing premature maintenance or replacement decisions.
3Measurement precision
If comprehensive detection of all influences is implemented, then prediction accuracy improves, but system complexity and cost increase significantly
Solution Approach 1:
The patent extracts and focuses only on the most influential factors that affect device behavior, rather than attempting to detect all possible influences. The behavioral model is trained to identify and learn from the key parameters that have the greatest impact on device performance. This selective approach maintains high prediction accuracy by concentrating resources on the most critical factors, while avoiding the complexity and cost of comprehensive detection systems that would attempt to monitor every possible influence.
