Assembly Generative Design with Spatial Constraint Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer-aided generative design tools are part-centric, requiring users to design each mechanical part individually and then manually ensure that they do not interfere with others in an assembly, leading to a time-consuming and error-prone process.
Innovation Solution
A system and method for generatively designing a model of an assembly of mechanical parts by receiving constraints for one part, determining the spatial relationship with another part, updating the constraints based on this relationship, and generating a model for each part to avoid interference, allowing for simultaneous design of multiple parts within an assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If parts are designed individually using traditional part-centric generative design tools, then each part can be optimized independently, but the parts may interfere or collide with one another when joined in an assembly, requiring iterative manual adjustments
Solution Approach 1:
The patent merges the design processes of multiple parts into a single integrated assembly-level generative design process. The system simultaneously generates multiple parts while maintaining their spatial relationships and preventing interferences, eliminating the need for sequential individual design and manual iteration.
Solution Approach 2:
The system implements feedback mechanisms where the spatial relationships and constraints between parts are continuously evaluated during the generative design process. Design constraints are automatically updated based on the generated geometry of other parts, enabling real-time coordination and conflict resolution without manual intervention.
2Adaptability or versatility
If modifications are made to one part in an assembly, then the design can be updated, but other interacting parts may also need to be separately altered, requiring multiple iterations to ensure compatibility
Solution Approach 1:
The system enables self-service design coordination where the generative design algorithm automatically adjusts other parts when one part is modified. The constraints and spatial relationships are maintained automatically through the integrated design process, eliminating the need for manual coordination of multiple part modifications.
Solution Approach 2:
The system provides a universal design platform that handles multiple parts and their interactions through a single generative design process. The same algorithm and constraint system are applied across all parts in the assembly, providing consistent and coordinated design modifications throughout the entire assembly.
3Reliability
If manual processes are used to ensure generated parts do not have incompatible interferences, then design accuracy can be maintained, but the process becomes time-consuming and error-prone
Solution Approach 1:
The patent replaces manual mechanical design processes with an automated computational generative design system. The algorithm automatically generates part geometries while enforcing spatial constraints and preventing interferences, substituting human manual checking and adjustment with automated computational methods that are both accurate and efficient.

AI summary
Methods and systems are disclosed for generatively designing a model of an assembly of mechanical parts. One method includes receiving a first set of constraints for a first part; determining a spatial relationship between the first part and a second part; updating the first set of constraints for the first part based on at least the spatial relationship between the first part and the second part; updating a second set of constraints for the second part based on at least the updated first set up constraints and/or the spatial relationship between the first part and the second part; and generating a model for the first part based on the updated first set of constraints.
