Surface-Specific Coordinate Data Isolation for Part Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current part inspection methods, such as mechanical inspection and laser scanning, are inefficient and fail to provide accurate, isolatable data for complex parts with numerous surfaces, making it difficult to diagnose issues effectively.
Innovation Solution
A system that compares a part's coordinate data to a computer model by aligning and correlating the data, selecting a surface for review, and excluding data from other surfaces, allowing for detailed comparison and reporting of differences specific to the chosen surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser scanning is used to obtain coordinate data for complex parts with hundreds or thousands of surfaces, then measurement precision and data quantity are improved, but the ability to isolate and diagnose specific surface problems deteriorates due to simultaneous reporting of all surfaces
Solution Approach 1:
The patent divides the complex part into multiple individual surfaces and enables selective reporting of comparison data for each surface separately. The software interface allows users to isolate and examine comparison data for specific surfaces rather than viewing all surfaces simultaneously, making diagnosis of problematic areas straightforward despite the part having hundreds or thousands of surfaces.
2Productivity
If mechanical inspection methods are used for part verification, then device complexity is reduced, but productivity and measurement precision deteriorate due to slow inspection speed and insufficient data
Solution Approach 1:
The patent replaces mechanical inspection methods (surface plate, height gage, rotary tables) with a laser scanning system that obtains coordinate data for hundreds of thousands of points per second. The laser scanner with software processing provides both high-speed data acquisition and comprehensive measurement capabilities that mechanical systems cannot achieve, despite the increased complexity of the scanning equipment.
3Loss of information
If comparison data for all surfaces is reported simultaneously, then completeness of inspection data is improved, but the ability to identify and analyze specific surface discrepancies deteriorates
Solution Approach 1:
The patent implements a dynamic reporting system where the software can selectively display comparison data for different surfaces based on user selection. Users can isolate specific surfaces for detailed examination while maintaining access to complete inspection data, allowing both comprehensive coverage and focused analysis of problematic areas.

Data Source
AI summary
A method and system of comparing a part to a computer model of the part obtains coordinate data for a plurality of points on a part, compares the coordinate data to a computer model of the part to obtain comparison data, reports the comparison data corresponding to a selected surface of the part, and excludes comparison data for all surfaces other than the selected surface.
