Engineering Contradiction Analysis
1Measurement precision
If traditional computational methods are used to generate conformers for complex organic molecules, then conformers can be produced with high accuracy, but the computational time and resource requirements increase significantly
Solution Approach 1:
The patent uses generative adversarial networks to create synthetic conformer data that copies the essential characteristics of authentic conformer data. The generator creates synthetic conformers that mimic the statistical and structural properties of real conformers, allowing the system to generate new conformer configurations without performing computationally intensive quantum mechanical calculations for each new conformer
Solution Approach 2:
The system performs preliminary training by generating a dataset of authentic conformers using traditional computational methods, then uses this pre-computed data to train the GAN model. Once trained, the model can rapidly generate new conformers without repeating the expensive computational steps, effectively performing the heavy computational work in advance
2Measurement precision
If traditional computational methods are used to identify relevant conformers, then accurate predictions can be made, but the computational resources and time required increase
Solution Approach 1:
The discriminator component learns to distinguish authentic conformers from synthetic ones by copying the recognition patterns of traditional computational methods. Once trained, it can rapidly evaluate new conformer configurations using the learned patterns rather than performing full computational analyses, reducing energy requirements while maintaining prediction accuracy
Solution Approach 2:
The patent replaces traditional mechanical computational methods with a machine learning-based system. The GAN model substitutes physics-based computational chemistry calculations with statistical pattern recognition, using learned representations to predict conformer properties without performing explicit quantum mechanical or molecular mechanical calculations
3Productivity
If hybrid GAN with quantum computing is used, then computational efficiency and accuracy are improved, but the system complexity increases
Solution Approach 1:
The patent divides the conformer generation system into distinct functional components: a quantum computing device for generating latent space representations, a classical computing device for running the GAN architecture, and various modules within the GAN (generator, discriminator, energy function). This segmentation allows each component to be optimized independently and facilitates implementation using available technology

AI summary
A generative system for producing one or more conformers of a selected molecule includes a processor, and a memory coupled to the processor, wherein machine-readable instructions are stored in the memory, and wherein the machine-readable instructions, when executed on the processor, configure the processor to receive by a generative model both a training dataset and an input dataset, and generate by the generative model one or more synthetic conformers of the selected molecule using the input dataset associated with the selected molecule.
