Solution Overview

Problem

Existing simulation models for drive devices are either overly complex or simplistic, lacking flexibility to adapt to specific user needs and computing resources, and often require full representation of the drive device, which is inefficient.

Innovation Solution

A modular, time-dependent simulation model with configurable modules that allow users to select and adjust the level of detail based on their specific interests and available resources, enabling flexible simulation of drive devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a comprehensive simulation model with full functional scope is created, then simulation accuracy is improved, but device complexity and computational resources increase

Engineering Contradiction:
Improvesimulation accuracyVSAvoidmodel complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The simulation model is divided into modular components representing different functional aspects of the drive device (electrical machine, supply unit, control device, environment). Each module can be independently configured and combined based on simulation needs, allowing comprehensive models to be built from smaller manageable pieces that can be optimized individually.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The model complexity is made dynamic and configurable rather than fixed. Users can adjust the level of detail and functional scope of each module based on their specific simulation requirements and available computational resources, transforming a static comprehensive model into a flexible adaptive system.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a detailed simulation model is created to cover all functions, then simulation completeness is improved, but ease of operation deteriorates due to parameterization complexity

Engineering Contradiction:
Improvesimulation completenessVSAvoidparameterization ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The parameterization process is segmented across modular components rather than requiring configuration of a monolithic model. Users only need to parameterize the modules relevant to their simulation objectives, reducing the overall parameterization burden while maintaining completeness for targeted simulations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular architecture creates universal building blocks that can be reused across different simulation scenarios. The same module library serves multiple simulation purposes, and users can combine modules in different configurations without reparameterizing entire models, improving both completeness and ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a simplified simulation model is used, then ease of operation is improved, but simulation accuracy deteriorates

Engineering Contradiction:
Improvemodel simplicityVSAvoidsimulation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The model allows dynamic adjustment of detail level based on simulation needs. Users can start with simplified models for quick assessments and easily enhance specific modules to increase accuracy when needed, rather than being locked into a fixed level of complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different modules can have different levels of detail and accuracy appropriate to their specific function. Critical components can be modeled with high precision while less important aspects use simplified representations, achieving overall accuracy where needed without unnecessary complexity elsewhere.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If a custom-specific simulation model is created for each customer need, then adaptability to specific requirements is improved, but device complexity increases

Engineering Contradiction:
Improvecustomer-specific adaptabilityVSAvoidmodel development complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A universal module library is created that can be reused across different customer-specific simulations. The same standardized modules serve multiple applications, and customization is achieved through selective combination and configuration rather than developing entirely custom models for each case, reducing development complexity while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The model development process is segmented into reusable component creation and custom assembly phases. Once modules are developed, they can be independently configured and combined for different applications without redesigning the entire model, separating the complex development work from the simpler customization process.

Inventive Principle:
Principle #1Segmentation
