Engineering Contradiction Analysis
1Reliability
If molecular simulation is performed using a single initial conformation, then the calculation speed is fast, but the reliability of solubility evaluation is low due to initial conformational dependence
Solution Approach 1:
The patent segments the molecular simulation process by dividing it into multiple parallel simulations, each starting from a different initial conformation. This allows the system to evaluate solubility across multiple conformational pathways simultaneously, improving reliability without proportionally increasing total computation time through parallel processing capabilities.
Solution Approach 2:
The patent performs preliminary conformational analysis and selection before the main solubility evaluation. By pre-identifying representative initial conformations that capture the essential conformational space, the system reduces the number of full simulations needed while maintaining evaluation reliability.
2Reliability
If multiple initial conformations are used for molecular simulation, then the reliability of solubility evaluation is improved, but the device complexity increases
Solution Approach 1:
The simulation system is segmented into modular functional units: conformation generation module, molecular simulation execution module, solubility calculation module, and analysis module. Each module handles a specific aspect of the multi-conformation evaluation, making the complex system manageable and maintainable while achieving reliable solubility predictions.
Solution Approach 2:
The patent implements a universal simulation framework that can handle multiple initial conformations through a standardized process flow. The same core simulation engine and calculation algorithms are reused across all conformational evaluations, reducing overall system complexity despite the increased number of simulations.
3Measurement precision
If multiple initial conformations are evaluated, then the accuracy of solubility features is improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary conformational sampling and clustering to identify representative initial conformations before the main solubility evaluation. This pre-processing step reduces the total number of full simulations required while ensuring that the conformational space is adequately sampled, thereby maintaining accuracy with reduced computational time.
Solution Approach 2:
The patent implements periodic evaluation cycles where simulations are performed in batches across multiple conformations, with intermediate analysis steps. This periodic structure allows for efficient resource utilization and early termination of clearly unfavorable conformations, reducing overall evaluation time while maintaining statistical accuracy.

AI summary
An initial conformation setting unit sets multiple different initial conformations. a solubility feature calculation unit calculates a solubility feature for each molecular simulation for each initial conformation. A partial three-dimensional structural information acquisition unit calculates partial three-dimensional structural information of a molecule in each molecular simulation. Based on a solubility feature and partial three-dimensional structural information for each molecular simulation, a partial structure specification unit specifies a partial structure corresponding to variation in the solubility features. A variation evaluation unit selects a group based on the thermodynamic stability of each group in which the solubility feature is classified based on the partial structure, and calculates variation in the solubility features. When the variation is equal to or greater than a target variation value, a variation determination unit causes multiple new initial conformations to be set. An output unit outputs the evaluation results when the variation is less than the target variation value.
