Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional lubricant monitoring methods are used, then implementation simplicity is maintained, but lubricant lifespan prediction accuracy deteriorates
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the physical asset that mirrors its lubrication system. This digital replica allows for complex simulations and predictions without requiring complex physical monitoring equipment on the actual asset. The digital twin copies the lubricant's state, operating conditions, and degradation patterns, enabling accurate lifespan prediction through virtual experimentation and analysis.
2Measurement precision
If real-time data collection from multiple sensors is implemented, then lubricant breakdown analysis accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent introduces a knowledge corpus as an intermediary layer between the sensor data and the analysis process. This knowledge corpus contains pre-processed, structured information about lubricant degradation patterns, operating conditions, and failure modes. Instead of directly processing raw sensor data, the system queries and compares data against this intermediary knowledge base, simplifying the processing complexity while maintaining high analysis accuracy.
3Productivity
If comprehensive simulations of multiple temporal sequences are performed, then maintenance optimization is improved, but computational time increases
Solution Approach 1:
The patent pre-generates and stores multiple temporal sequences of lubricant degradation patterns under various operating conditions in the knowledge corpus during system setup or idle periods. When maintenance optimization is needed, the system doesn't perform comprehensive simulations from scratch but rather queries and analyzes pre-computed sequences that match current operating conditions, significantly reducing computational time while maintaining optimization quality.

AI summary
Systems, methods and computer program products leveraging digital twin modeling and cognitive computing to predict lubrication replacement for a physical asset. Predictions of lubrication replacement consider one or more various parameters such as operating conditions, usage parameters, the surrounding environment, overall health and state of repair of the physical asset, lubricant properties and historically collected data from the physical asset (or similarly comparable assets). Timing for optimal lubrication replacement is identified using the collected data of the physical asset, along with historical data, to simulate changes in a state of lubricants and lubricated parts within a physical asset using digital twin modeling to make predictions how one or more actions upon the physical asset impact the health, stability and/or longevity of the lubricant's lifespan. Based on the simulation results, recommended action(s) suitable for increasing and optimizing the overall life of the lubrication are provided and/or implemented.
