1Measurement precision
If traditional chemical synthesis methods are used for molecular synthesis and reaction prediction, then researchers can obtain experimental results, but the process consumes a lot of time and cost
Solution Approach 1:
The patent creates a virtual copy of the chemical reaction process through a computational prediction model that simulates molecular structures and reaction outcomes. Instead of physically performing experiments, the system uses graph-based molecular representations and neural network models to predict reaction products, thereby eliminating the time-consuming experimental process while maintaining prediction accuracy.
Solution Approach 2:
The patent replaces the mechanical experimental process with a computational system. The chemical reaction prediction is achieved through electronic computation using graph neural networks and diffusion models, substituting the physical laboratory process with an in silico system that provides rapid predictions without consuming physical reagents or equipment time.

Solution Approach 2:
The patent uses computational resources instead of expensive physical reagents and equipment. The molecular structures are represented as data objects (graphs) that can be processed indefinitely without consumption, replacing costly physical chemicals with inexpensive digital representations that have no material cost.
3Productivity
If a chemical reaction prediction model is developed to reduce research time and cost, then prediction efficiency increases, but the model complexity increases
Solution Approach 1:
The patent segments the chemical reaction prediction task into distinct computational modules: molecular structure representation as graphs, reaction mechanism modeling through diffusion processes, and product prediction via neural networks. This segmentation allows each component to be optimized independently, managing overall system complexity while maintaining high prediction efficiency.
Solution Approach 2:
The patent introduces graph-based molecular representations as an intermediary between the input chemical structures and the prediction output. This intermediate representation standardizes diverse molecular inputs into a unified graph format, simplifying the subsequent prediction process and enabling efficient processing while managing model complexity through standardized data structures.
