Analysis Property Transfer Between Geometry Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in re-specifying analysis properties for geometry models during design changes leads to costly delays in the product development cycle, as existing methods require costly re-assignment of properties for each model change and are limited to specific CAD environments.
Innovation Solution
A system and method for transferring analysis properties between geometry models using a coordinate system-based mapping, where properties are assigned to voxels and interpolated or extrapolated to corresponding components in the new model, enabling efficient property mapping across different CAD packages and models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If analysis properties are re-specified for each model change, then analysis accuracy is maintained, but time consumption and cost increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-defining analysis properties on the source model and establishing a mapping relationship between source model components and target model components before the actual analysis. This allows properties to be automatically transferred when models change, eliminating the need for re-specification while maintaining accuracy. The mapping relationship is created in advance, so when geometry changes occur, the pre-established connections enable automatic property transfer.
Solution Approach 2:
The patent implements copying by transferring analysis properties from the source model to the target model through established mapping relationships. Instead of re-specifying properties, the system copies property values from corresponding components in the source model to components in the target model. This copying mechanism maintains analysis accuracy while dramatically reducing the time and effort required compared to manual re-specification.
2Manufacturing precision
If analysis properties are manually re-assigned for each design iteration, then property accuracy is ensured, but productivity decreases
Solution Approach 1:
The system performs preliminary action by establishing component mapping relationships between source and target models before property transfer. This pre-established mapping enables automatic property assignment during design iterations, ensuring that properties are accurately assigned to corresponding components without manual intervention. The mapping relationship is created once and reused across multiple iterations, maintaining precision while boosting productivity.
Solution Approach 2:
The patent applies self-service by enabling the system to automatically transfer analysis properties from source to target models using pre-defined mapping relationships. The system serves itself by automatically identifying corresponding components through the mapping and assigning properties without requiring analyst intervention. This self-service mechanism ensures property accuracy while dramatically increasing design iteration speed.
3Adaptability or versatility
If properties are transferred between different CAD environments, then design flexibility improves, but compatibility challenges arise
Solution Approach 1:
The patent applies universality by creating a mapping relationship system that works across different CAD environments and model types. The mapping mechanism is designed to be environment-agnostic, allowing properties to be transferred between different CAD packages and model representations. This universal approach enables design flexibility across platforms while maintaining reliability through consistent property transfer mechanisms.
Solution Approach 2:
The patent uses an intermediary approach by introducing a mapping relationship as a mediator between source and target models from different CAD environments. This mapping layer translates between different CAD representations, enabling property transfer across incompatible systems. The intermediary mapping ensures compatibility while preserving design flexibility, as it handles the translation between different CAD environments without requiring direct integration.

AI summary
A system enables a transfer of analysis properties between geometry models and includes a memory for storing analysis properties of a first model that includes a plurality of components, each component assigned to one or more of the analysis properties and each component assigned to one or more voxels in a coordinate system based on component location. The system includes a processor programmed to receive data corresponding to a second model comprising a plurality of components, access analysis properties of the first model, apply the coordinate system to the second model, using the coordinate system and analysis properties assigned to each voxel in the coordinate system, map the plurality of components of the second model to one or more voxels in the coordinate system, and assign analysis properties of the first model to components of the second model based on voxel mapping to the components of the second model.
