CAD Model Discrepancy Identification for Design Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current design revision techniques for industrial machine parts, such as gas turbine systems, lack efficient methods to quickly identify and document changes between different versions of CAD models, leading to potential unintended modifications and difficulties in verifying desired changes.
Innovation Solution
A computer-aided design (CAD) comparison tool that identifies and documents discrepancies between different CAD model versions, allowing users to review and verify changes, and generate documentation for downstream manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual design revision review methods are used, then users can examine design changes, but the process is time-consuming and error-prone
Solution Approach 1:
The patent replaces manual mechanical review processes with an automated computer-based system that uses software to compare CAD models, extract change information, and generate discrepancy reports automatically, eliminating the need for manual examination of design revisions
Solution Approach 2:
The patent introduces an intermediary computer-based comparison system that acts as a mediator between different CAD model versions, automatically identifying and documenting discrepancies without requiring direct human intervention in the comparison process
2Reliability
If comprehensive design change tracking is implemented, then all modifications can be identified, but the complexity of the review process increases
Solution Approach 1:
The patent segments the design review process into distinct automated steps: model comparison, discrepancy extraction, categorization, and report generation. This breaks down the complex verification task into manageable automated components that can be executed systematically
Solution Approach 2:
The system performs self-service by automatically comparing CAD models, identifying discrepancies, and generating documentation without requiring external manual intervention, thereby reducing system complexity while maintaining comprehensive verification
3Manufacturing precision
If detailed discrepancy documentation is generated, then manufacturing accuracy is improved, but the time required for documentation increases
Solution Approach 1:
The patent replaces manual documentation processes with automated computer-based generation of discrepancy reports, extracting change information directly from CAD model comparisons and formatting it for manufacturing use without manual intervention
Solution Approach 2:
The system performs preliminary extraction and categorization of change information during the automated comparison process, preparing manufacturing documentation in advance before the actual manufacturing process begins, thereby accelerating the overall workflow
Data Source
AI summary
A system includes a display and a processor. The processor is configured to receive a first computer-aided design (CAD) model representing at least one part of a machine, receive a second CAD model representing the at least one part of the machine, and identify one or more differences between the first CAD model and the second CAD model. The processor is also configured to populate a discrepancy list including the one or more differences between the first CAD model and the second CAD model, receive an input to review the discrepancy list, and display a visualization having the discrepancy list via the display upon receipt of the input.
