Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the reverse Monte Carlo method is used to determine the three-dimensional structure of a target sample from scattering data, then the accuracy of the three-dimensional structure model is improved, but the computation time increases significantly

Engineering Contradiction:

Improveaccuracy of three-dimensional structure modelVSAvoidcomputation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent pre-calculates and stores three-dimensional structure models for multiple samples with known structures in a database before actual analysis. When analyzing a target sample, the system retrieves pre-computed models that match the scattering data pattern, avoiding the need to perform computationally intensive reverse Monte Carlo calculations in real-time. This preliminary preparation resolves the contradiction by trading initial computational effort for rapid subsequent analysis.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a database of pre-computed three-dimensional structure models that serve as templates or copies. Instead of performing complex calculations on the target sample itself, the system finds and retrieves matching pre-computed models from the database. This copying approach maintains high accuracy while dramatically reducing computation time during actual analysis.

Inventive Principle:

Principle #26Copying

2Reliability

If the reverse Monte Carlo method is used to obtain the three-dimensional structure of particles constituting a sample, then the reliability of the structure determination is improved, but the productivity of the analysis process decreases

AI summary

A server receives target sample data sent from the user equipment, and searches sample data in a database using the target sample data as a search query to identify the sample data whose similarity measure to the target sample data is equal to or greater than a threshold. The server identifies a three-dimensional structure model associated with the identified sample data, and outputs the identified three-dimensional structure model as a three-dimensional structure model corresponding to the target sample data.
