Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If line notations are used to represent chemical structures, then computers can easily process linear strings of data, but the representations do not scale and do not accurately describe polymeric/stochastic materials, composites, or complexes
Solution Approach 1:
The patent segments the representation of chemical structures into graph-based components where molecules are represented as graphs with nodes for atoms and edges for bonds. This segmentation allows accurate representation of complex polymeric materials while maintaining computational processability through standardized graph data structures.
Solution Approach 2:
The patent changes the representation parameters from linear string formats to graph-based structures with specific node and edge attributes. This parameter change enables accurate encoding of polymeric material characteristics including connectivity, topology, and chemical features while preserving ease of computer processing.
2Adaptability or versatility
If a single knowledge graph schema is used to embed all materials data, then all materials data can be unified, but there is no mechanism to determine how individual polymer features and components are reflected, leading to data mining redundancy and repetition
Solution Approach 1:
The patent segments the knowledge graph into hierarchical structures where polymer features, components, and materials are represented as distinct graph elements with defined relationships. This segmentation allows the system to distinguish between different levels of material organization, eliminating redundancy while maintaining unified data representation.
Solution Approach 2:
The patent adds dimensional hierarchy to the knowledge graph representation, organizing materials data across multiple levels from atomic components to polymer features to bulk materials. This dimensional structure enables efficient data mining by allowing queries to navigate through hierarchical relationships without redundancy.
3Duration of action of stationary object
If traditional line notations are used for chemical structures, then existing systems can be maintained, but query efficiency for polymeric materials is poor and data modeling is redundant
Solution Approach 1:
The patent creates a universal graph-based representation system that can handle both traditional small molecules and complex polymeric materials using the same fundamental data structure. This multi-functionality allows the system to maintain compatibility with existing cheminformatics tools while dramatically improving query efficiency for polymeric materials.
Data Source
AI summary
A computational system, which may be an artificial intelligence (AI) system, allows for the electronic representation, modeling, generation, rendering, simulating, and querying of polymeric materials by encoding architectural features as nodes and embedding a directed graph of the polymeric materials within a database system. The embedding of chemical data from multiple nodes within the directed graph data structure enables a scalable data model for containing materials data within computational systems. The computational system may be used for predictive modeling of new polymeric materials and for rendering and/or simulating stochastic polymeric ensembles.
