Engineering Contradiction Analysis
1Measurement precision
If manual synchronization methods are used to align simulation models with real systems, then synchronization accuracy can be achieved, but the time and effort required increase significantly
Solution Approach 1:
The patent replaces manual mechanical synchronization operations with an automated mathematical calculation system. The device model with inverse functions automatically calculates input values from output values, substituting the manual alignment process and achieving both high accuracy and time efficiency.
Solution Approach 2:
The patent uses the device model as a mathematical copy of the real device's input-output relationship. By creating and using this mathematical model with inverse functions, the system can automatically determine input values without physically accessing or manually configuring the real device, thus reducing time while maintaining accuracy.
2Reliability
If detailed device models are used to accurately represent real devices, then simulation fidelity improves, but model complexity and setup effort increase
Solution Approach 1:
The patent extracts only the essential input-output relationship from the complex real device and represents it through a simplified mathematical function in the device model. This allows the model to capture the critical behavior needed for synchronization without replicating the full physical complexity of the actual device.
Solution Approach 2:
The patent transforms the complex physical device into a mathematical representation by changing parameters from physical dimensions to mathematical functions. The device model uses mathematical parameters and functions to represent device behavior, simplifying the model structure while maintaining its ability to accurately simulate device characteristics through the inverse function mechanism.
