CAD Attribute Propagation for Design Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing attributes of computer-aided design (CAD) models lack efficiency in applying modifications across related features and components, leading to manual errors and increased design time in complex industrial machine parts like gas turbines.
Innovation Solution
A processor-based system and method that identifies and modifies related attributes and programming objects within CAD models, allowing for the application of changes made to one aspect of a model to be automatically implemented across other similar aspects, using an attribute managing application to generate callouts and manage hierarchical relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to manage and modify CAD model attributes, then flexibility in individual customization is maintained, but productivity is reduced and errors increase
Solution Approach 1:
The system enables self-service automation where the CAD model automatically identifies and propagates attribute modifications across related features without requiring manual intervention. The attribute management system monitors changes and automatically updates dependent attributes, allowing the design system to serve itself in maintaining consistency across the model.
Solution Approach 2:
The system implements feedback mechanisms where modifications to CAD model attributes are automatically detected and propagated to related attributes. The system continuously monitors attribute changes and provides automatic feedback updates across the model hierarchy, ensuring consistency without manual intervention and significantly improving design productivity.
2Manufacturing precision
If individual attribute modifications are made manually, then precision in specific changes is maintained, but time consumption increases
Solution Approach 1:
The system establishes preliminary relationships and dependencies between CAD model attributes before modifications occur. By pre-defining how attributes are related and how changes should propagate, the system ensures that when modifications are made, they are automatically and accurately applied to all related attributes without manual intervention, reducing design time while maintaining precision.
Solution Approach 2:
The system automatically copies attribute modification patterns across related features. When an attribute is modified in one location, the system identifies related attributes through predefined relationships and automatically copies the modification pattern, ensuring consistency and accuracy across the entire model while dramatically reducing the time required compared to manual updates.
3Stability of the object's composition
If comprehensive attribute tracking is implemented across all model features, then design consistency is improved, but system complexity increases
Solution Approach 1:
The system segments attribute relationships into hierarchical levels and categories, managing complexity by organizing attribute dependencies in a structured manner. Rather than tracking all attributes uniformly, the system divides them into groups with defined relationships, allowing comprehensive tracking while maintaining manageable system complexity through organized segmentation of the attribute management structure.
Data Source
AI summary
A system includes a processor configured to receive a modification to a first set of data associated with a first set of properties of a computer-aided design (CAD) model and identify a second set of data associated with a second set of properties of the CAD model based on the first set of data. The first and second sets of properties are related. The processor is also configured to modify the second set of data based on the modification to the first set of data.
