Engineering Contradiction Analysis
1Measurement precision
If experimental measurement is used to obtain interface layer thickness, then measurement precision is improved, but loss of time and cost increase
Solution Approach 1:
The patent creates a virtual copy of the macromolecular material-filler system through computer simulation. The simulation model replicates the physical system's behavior, allowing interface layer thickness to be measured in the virtual model without time-consuming physical experiments. The simulation produces accurate measurements by modeling molecular dynamics and interaction potentials, eliminating the need for actual material production and measurement.
Solution Approach 2:
The patent replaces the mechanical/experimental measurement system with a computational simulation system. Instead of physically producing materials and using experimental apparatus to measure interface layer thickness, the invention uses computer-based molecular dynamics simulations to calculate the thickness directly from modeled interactions between filler particles and macromolecular chains.

3Productivity
If conventional simulation methods are used, then productivity is improved, but measurement precision deteriorates due to reliance on experimental data input
Solution Approach 1:
The patent enables the simulation system to determine interface layer thickness independently without requiring external experimental measurements. The simulation model self-calibrates by using interaction potentials between filler particles and macromolecular chains to naturally produce the interface layer structure during molecular dynamics evolution. The system generates its own measurement data from the simulated physical chemistry, eliminating dependency on experimental input while maintaining both speed and accuracy.

AI summary
A computer simulation method for a macromolecular material and filler is disclosed, wherein a polymer model of a macromolecular chain of the macromolecular material and a filler model of the filler are defined; and a molecular dynamics calculation is performed using the filler model and the polymer models disposed in a space in order to compute the thickness of an interface layer between the filler and the macromolecular material. To compute the thickness, the space is partitioned into domains bounded by boundary surfaces; relaxation moduli of the domains are computed; and based on a variation of the relaxation moduli of the domains, the thickness of the interface layer is computed.
