Solution Overview

Problem

Combining micro-simulation models for entire product simulations increases calculation complexity due to the need for finer time units and interaction simulations, which existing methods struggle to address effectively.

Innovation Solution

A simulation apparatus that performs coupled simulations using micro-models, learns the correspondence between inputs and outputs over time, and generates a macro-model to infer outputs after a period, reducing the need for detailed micro-model simulations in overall simulations.

VSEngineering Contradiction Analysis

1Measurement precision

If multiple micro-models are combined for coupled simulation to simulate entire product behavior, then simulation accuracy and comprehensiveness are improved, but calculation amount and device complexity increase significantly

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the simulation system into multiple independent micro-models, each representing a specific element or component. These micro-models can be developed, validated, and managed independently, then coupled together through standardized interfaces to simulate overall product behavior. This segmentation allows high simulation accuracy through detailed element-level modeling while managing complexity through modular architecture.

Core Design Contradiction:

Solution Approach 1:

The patent implements a periodic coupling mechanism where micro-models are simulated independently over coarse time intervals, and interactions are updated at periodic checkpoints. This allows each micro-model to maintain high precision with fine time steps internally, while the overall coupled simulation progresses efficiently through coarse time units. The periodic synchronization reduces the total number of interaction calculations required compared to continuous fine-grained coupling.
