Dynamic Checker Validation for CAD Product and Manufacturing Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-aided design (CAD) tools face challenges in validating product and manufacturing information (PMI) due to the tedious and error-prone nature of manual validation and the limitations of out-of-the-box checkers, which are based on fixed logic and fail to comply with evolving standards and contextual variations.
Innovation Solution
A method and system that dynamically identifies, modifies, or generates checkers to validate PMI by extracting logical elements from a checker database, ensuring compliance with standard criteria, and outputs results on a graphical user interface, allowing for real-time validation of PMI in a CAD environment.

Engineering Contradiction Analysis
1Extent of automation
If out of box checkers are used for validating product and manufacturing information, then validation can be automated, but the checkers cannot adapt to evolving standards and contextual variations
Solution Approach 1:
The validation system transitions from static out-of-box checkers to dynamic checkers that can be modified at runtime. The checker database stores multiple checkers with different logical elements, and the system dynamically selects and modifies checkers based on evolving standards and contextual requirements, allowing the validation process to adapt without manual reconfiguration
Solution Approach 2:
The system changes the parameters of checkers by modifying their logical elements. The checker modification process alters the logical elements within checkers to reflect updated standards and contextual variations, enabling the same checker framework to handle different validation requirements through parameter changes rather than structural redesign
2Reliability
If manual validation techniques are used, then complete validation according to evolving standards can be achieved, but the process becomes tedious and error-prone
Solution Approach 1:
The validation system performs self-service by automatically identifying, selecting, and modifying appropriate checkers from the checker database based on the geometric model and applicable standards. This eliminates the need for manual validation while maintaining completeness, as the system autonomously adapts checkers to meet evolving standards and contextual requirements
Solution Approach 2:
The system incorporates feedback mechanisms where validation results and standard requirements inform the selection and modification of checkers. The validation process continuously refines checker configuration based on feedback from geometric model analysis and standard compliance requirements, ensuring both completeness and efficiency
3Device complexity
If fixed logic checkers are used, then validation process is simple, but the checkers cannot comply with evolving standards and contextual variations
Solution Approach 1:
The validation system segments the checker functionality into modular logical elements that can be independently modified. Each checker consists of discrete logical elements that can be selectively adjusted to comply with evolving standards, maintaining overall process simplicity while enabling targeted adaptations without redesigning the entire validation framework
