Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional simulation software is used to solve constrained optimization models for plant loading simulation, then the simulation can be performed, but the process becomes resource intensive and has low adaptability when process flows change
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the processing plant that mirrors the physical system's behavior. This digital twin is trained on historical operational data to learn and predict plant loading characteristics, replacing the need for repeated resource-intensive simulations while maintaining high adaptability to process flow changes.
Solution Approach 2:
The patent transforms the simulation approach by changing from solving constrained optimization models with fixed parameters to using a machine learning model with learned parameters from historical data. This allows the system to adapt to new process flows by retraining on new data rather than requiring complete re-simulation, reducing resource requirements while improving adaptability.
2Productivity
If traditional simulation models are used for plant loading prediction, then the simulation can be performed, but the process is time consuming and requires repeated simulations when process flows change
Solution Approach 1:
The patent performs preliminary training of the machine learning model using historical operational data before actual prediction is needed. This pre-learning phase captures the complex relationships in the system, enabling rapid predictions later without requiring time-consuming repeated simulations when process flows change.
Solution Approach 2:
The patent replaces the mechanical simulation process (solving constrained optimization models) with an intelligent system (machine learning model). This substitution eliminates the need for repeated computational simulations, dramatically reducing prediction time while maintaining accuracy through patterns learned from historical data.
3Productivity
If input flow rates are adjusted to increase output flow rates, then plant performance can be optimized, but the process requires complex simulation and analysis
Solution Approach 1:
The patent implements a feedback mechanism where the machine learning model continuously learns from historical operational data, including the relationships between input flow rates and output flow rates. This feedback loop enables the system to automatically identify optimal adjustments without requiring complex simulation and analysis, directly linking cause and effect through learned patterns.
