Engineering Contradiction Analysis
1Manufacturing precision
If traditional experimental methods are used to optimize separation parameters, then separation efficiency can be improved, but the number of experiments required increases significantly, consuming more time and resources
Solution Approach 1:
The patent replaces the traditional mechanical/experimental trial-and-error approach with a computational simulation system. A virtual model of the separation apparatus is created, and numerical simulations are performed to predict separation outcomes for different parameter combinations, eliminating the need for numerous physical experiments while maintaining optimization accuracy
Solution Approach 2:
The patent performs preliminary computational analysis by creating a virtual model and running simulations before actual experiments. This preliminary action identifies optimal parameter ranges and predicts separation outcomes, allowing researchers to focus experimental efforts only on the most promising conditions, thereby reducing the total number of experiments needed
2Measurement precision
If separation methods are optimized for specific apparatuses through extensive experimentation, then accuracy improves, but transferability to different apparatuses deteriorates
Solution Approach 1:
The patent creates a universal virtual model framework that can represent different separation apparatuses through standardized parameters and geometry definitions. The same simulation software and methodology can be applied across various apparatus types (HPLC, UHPLC, different column configurations), allowing methods optimized for one apparatus to be transferred to others by simply modifying model parameters rather than redeveloping entire separation protocols
3Measurement precision
If more sensors and measurement devices are added to monitor separation processes, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent creates a virtual copy (digital twin) of the separation apparatus that replicates its physical behavior through numerical simulations. This virtual model receives input parameters and produces predicted separation outcomes, serving as a computational surrogate that eliminates the need for complex physical sensing and measurement systems while maintaining predictive accuracy

AI summary
A process of determining a modified separation method for a sample separation apparatus based on an initial separation method, including carrying out the initial separation method on a sample separation apparatus, detecting sensor data at the sample separation apparatus during carrying out the initial separation method, and carrying out a numerical analysis for determining the modified separation method by modifying at least one operation parameter of the initial separation method and by using the detected sensor data.
