Solution Overview
Problem
There are issues with data loss and distortion during the transmission of design profiles from CAD to CAE systems, leading to challenges in achieving effective analysis and data compatibility.
Innovation Solution
A method is introduced where a design model is transformed into a neutral file format, allowing it to be readable and accessible by both CAD and CAE systems without requiring integration or licenses, enabling efficient optimization and analysis by assigning labels and modifying geometrical data within these systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary file formats are used in CAD and CAE systems, then each system can access its native data efficiently, but data loss and distortion occur during transmission between systems
Solution Approach 1:
The patent introduces a neutral file format as an intermediary between CAD and CAE systems. This neutral format serves as a common language that both systems can read and write without requiring integration or shared licenses. The neutral file format includes standardized fields for geometrical data, topological data, and labeling information, ensuring accurate data transmission while maintaining compatibility between different systems.
Solution Approach 2:
The neutral file format is designed to be universally compatible with both CAD and CAE systems. It can be exported from CAD systems and imported into CAE systems, and vice versa, without requiring system-specific proprietary formats. This universality eliminates the need for system integration while maintaining data integrity throughout the design-analysis-optimization cycle.
2Loss of information
If CAD and CAE systems are integrated, then data transmission can be maintained, but system complexity and licensing requirements increase
Solution Approach 1:
Rather than integrating CAD and CAE systems directly, the patent uses a neutral file format as an independent intermediary layer. This approach maintains data compatibility between systems without requiring any integration between the CAD and CAE software themselves. Each system operates independently with its own license and core databases, exchanging data through the standardized neutral format.
3Productivity
If proprietary file formats are used, then system-specific data access is efficient, but communication between different systems becomes problematic
Solution Approach 1:
The neutral file format provides universal compatibility across different CAD and CAE systems while maintaining efficient data access. The format includes standardized structures for geometrical data, topological data, and labeling that can be efficiently parsed by any system that supports the neutral format, eliminating the need for system-specific proprietary formats.

AI summary
The present application discloses a method of optimizing a design model. The method includes providing the design model in a CAD system, wherein the design model includes an object entity represented by a geometrical data and a topological data; assigning a first label to the object entity in the CAD system; transforming the first label into a second label to establish a first mapping in the CAD system; exporting a first neutral file of the design model including the second label, the geometrical data and the topological data from the CAD system; importing the first neutral file into a CAE system and transforming the second label into a third label to establish a second mapping in the CAE system; analyzing the design model by the CAE system; deriving a first modified geometrical data for the object entity based on the analysis for optimizing the design model by an optimization system; exporting a first data file including the first modified geometrical data for the object entity, and the second label derived from the third label based on the second mapping stored in the CAE system; importing the first data file into the CAD system and transforming the second label into the first label based on the first mapping stored in the CAD system; and replacing the geometrical data of the object entity assigned the first label with the first modified geometrical data in the first data file to generate a first modified design model in the CAD system.
