Engineering Contradiction Analysis
1Measurement precision
If simple models are used to relate covalent structure to function, then the model complexity is low and ease of manufacture is improved, but the prediction accuracy and reliability deteriorate because higher-order interactions are not captured
Solution Approach 1:
The patent transforms the molecular structure description from simple component lists to a comprehensive parameter set including covalent structure, component properties, and their interactions. This parameter expansion enables the model to capture higher-order interactions while maintaining a systematic approach to complexity management.
Solution Approach 2:
The patent creates a composite modeling approach that integrates multiple description levels (covalent structure, components, properties, interactions) into a unified predictive framework. This composite model combines simple and complex elements to achieve both interpretability and accuracy.
2Reliability
If higher-order interactions between multiple components are considered, then the prediction accuracy is improved, but the computational complexity and device complexity increase
Solution Approach 1:
The patent segments the molecular system into distinct hierarchical levels (covalent structure, components, properties, interactions) that can be analyzed and modeled separately. This segmentation allows complex higher-order interactions to be broken down into manageable computational units while preserving their collective impact on function.
Solution Approach 2:
The patent develops a universal algorithmic framework that can handle multiple types of interactions (adjacent components, distributed components, component-ligand interactions) within a single cohesive model. This multi-functional approach improves reliability across diverse biological systems without requiring separate complex models for each interaction type.
3Measurement precision
If comprehensive structural and interaction data are analyzed, then the functional prediction accuracy is improved, but the data processing time and loss of time increase
Solution Approach 1:
The patent performs preliminary organization and standardization of structural and interaction data before applying the predictive algorithm. By pre-processing and structuring the comprehensive data set in advance, the system reduces computational overhead during the actual prediction phase, thereby minimizing time loss while maintaining high prediction precision.
