Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current design verification systems for 3D-CAD data face challenges in managing and updating numerous design requirements, especially for complex shapes like aircraft or automobiles, due to the lack of systematic organization and the need for specialized programming knowledge, leading to potential manufacturing delays and redesigns.
Innovation Solution
A design support system that includes a common module database, a rule file database, and a design support apparatus to verify 3D-CAD data against design requirements, using a rule file creation process and design verification program to systematically check for compliance with design rules, facilitating the use of common modules to extract verification features and determine violations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If design verification systems are created one by one according to design requirements, then verification accuracy is improved, but system complexity and maintenance difficulty increase significantly
Solution Approach 1:
The patent segments the design verification system into independent modules: a rule file database storing design requirements, a verification program database storing verification logic, and a verification execution unit. Each module can be independently updated and maintained, reducing overall system complexity while maintaining verification accuracy.
Solution Approach 2:
The patent creates a universal verification framework that can handle multiple design requirements through a common architecture. The verification program database stores reusable verification logic that can be applied across different design scenarios, eliminating the need to create entirely new verification systems for each requirement.
2Reliability
If design verification systems are created one by one according to design requirements, then verification completeness is improved, but update efficiency deteriorates due to lack of systematic organization
Solution Approach 1:
The patent pre-organizes design requirements into a structured rule file database with standardized formats and categories. This preliminary organization allows verification programs to systematically access and apply multiple design requirements without ad-hoc configuration, ensuring completeness while enabling efficient updates through centralized database management.
3Extent of automation
If shape recognition is used to automatically identify locations corresponding to design requirements, then verification automation is improved, but accuracy deteriorates when design requirements are not systematically organized
Solution Approach 1:
The patent introduces an intermediary layer between shape recognition and design requirements: a rule file database that systematically organizes design requirements with standardized structures. This intermediary enables automated verification by providing a structured interface that shape recognition algorithms can systematically query and match against 3D-CAD data, improving both automation and accuracy.

AI summary
A design support system for verifying 3D-CAD data includes a common module database storing a plurality of common modules for processing the 3D-CAD data, a rule file database which stores a plurality of rule files for defining a procedure for obtaining a verification feature amount from the 3D-CAD data, and violation information based on the verification feature amount using the common module, and a design support apparatus. The design support apparatus calls a common module according to the procedure defined in the rule file and executes the common module on the 3D-CAD data, and determines whether the design requirement is violated on the basis of the violation information defined in the rule file and the verification feature amount obtained according to the procedure.
