Solution Overview

Problem

Current computer-aided engineering (CAE) systems, particularly in finite element analysis (FEA), lack integration of artificial intelligence (AI) for post-processing and design modification, limiting the ability to effectively utilize qualitative analysis results for design improvements.

Innovation Solution

A rule-based suggestion engine is implemented, using a knowledge base and inference engine to generate redesign recommendations for simulated models, allowing users to interactively view and select design modifications based on performance analysis, with features for parallel processing and varying levels of detail and abstraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If AI methods are applied to post-processing and design modification in FEA, then design improvement capability is enhanced, but system complexity increases

Engineering Contradiction:
Improvedesign modification automationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system segments the design improvement process into distinct modular components: FEA simulation module, post-processing module with qualitative result extraction, AI-based inference engine, and design modification module. Each module operates independently with defined interfaces, allowing the complex AI-driven design improvement system to be managed through separate, manageable functional blocks that can be developed and maintained independently.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If qualitative description of engineering analysis results is used, then system generality and applicability improve, but information precision may be reduced

Engineering Contradiction:
Improvesystem generalityVSAvoidanalysis result precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system applies local quality by extracting specific qualitative characteristics from different regions of the FEA results based on local structural features and failure modes. Instead of uniformly processing all results, the post-processing module identifies critical areas (such as high-stress regions or potential failure points) and extracts针对性 qualitative descriptions for those specific locations, maintaining precision where needed while achieving generality across different analysis types.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If intelligent interpretation of analysis results is implemented, then design modification accuracy improves, but processing time increases

Engineering Contradiction:
Improvedesign modification accuracyVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-defining a knowledge base of design patterns, failure modes, and modification strategies before the actual design improvement process. The AI inference engine is pre-trained with engineering knowledge and common design solutions, allowing it to quickly match qualitative analysis results with appropriate modification recommendations without requiring extensive real-time computation, thus reducing processing time while maintaining accuracy.

Inventive Principle:
Principle #10Preliminary action
