Solution Overview

Problem

Current methods struggle to accurately predict the physical properties of polymers due to the complexity of molecular structures, which are not fully represented by individual descriptors, and lack sufficient correlations between calculated and measured properties, limiting the ability to determine suitable applications and generate comprehensive polymer databases.

Innovation Solution

A computer-based system that receives descriptors from multiple groups (atomic species count, functional count, monomer species count, etc.) to determine prediction scores for target polymers based on pre-existing polymer data, providing physical property data and formulas for raw materials, thereby enhancing prediction accuracy and database generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If individual molecular descriptors are used to represent polymer structure, then the representation is simple, but the accuracy of predicting physical properties deteriorates due to insufficient capture of molecular complexity

Engineering Contradiction:
Improvedescriptor representation simplicityVSAvoidphysical property prediction accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the molecular structure representation into multiple descriptor groups (atomic species, functional groups, monomer species, bonds, morphology, topology, stereochemistry, etc.), where each group captures specific structural aspects. This segmentation allows comprehensive representation of polymer complexity while maintaining organized, manageable descriptor sets that can be systematically applied to predict physical properties.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a composite descriptor system that integrates multiple types of molecular descriptors (atomic, functional, monomer, bond, morphology, topology, stereochemistry) into a unified representation framework. This composite approach combines the strengths of different descriptor types to achieve accurate physical property predictions while systematically representing the complex polymer structure.

Inventive Principle:
Principle #40Composite materials

2Measurement precision

If comprehensive descriptor groups are used to accurately represent polymer structure, then prediction accuracy improves, but the complexity of the system increases

Engineering Contradiction:
Improvephysical property prediction accuracyVSAvoiddescriptor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the comprehensive descriptor system into seven distinct descriptor groups (atomic species, functional groups, monomer species, bonds, morphology, topology, stereochemistry), each with specific sub-descriptors. This segmentation reduces system complexity by organizing numerous descriptors into structured categories, making the comprehensive representation more manageable and systematically applicable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces multiple dimensions of structural representation by adding descriptor groups across different structural levels (atomic → functional → monomer → bond → morphology → topology → stereochemistry). This dimensional expansion allows comprehensive property prediction without overwhelming complexity, as each dimension addresses specific structural aspects independently.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If manual measurements are used to determine polymer properties, then the data is accurate, but the productivity and ability to generate comprehensive databases deteriorates

Engineering Contradiction:
Improveproperty data accuracyVSAvoiddatabase generation efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual measurement mechanisms with a computational prediction system that uses molecular descriptors and machine learning models to calculate physical properties. This substitution eliminates the need for time-consuming manual experiments while maintaining accurate property determination, thereby dramatically improving productivity and enabling comprehensive database generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent performs preliminary computational analysis by calculating molecular descriptors from polymer structure data before physical property prediction. This preliminary structuring of molecular information enables efficient batch processing of multiple polymers, allowing comprehensive database generation without repeated manual measurements for each polymer.

Inventive Principle:
Principle #10Preliminary action
