Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual and automated solutions for dimensioning cross sections of structures, such as aircraft parts, are time-consuming and error-prone, especially for complex shapes with holes or rotations, and often require extensive rework for minor changes.
Innovation Solution
A method and system for defining and dimensioning cross sections with arbitrary shapes, involving the creation of a vector graphic in 2D space, disassembly into paths, arrangement, and generation of an array of elements to produce a definition, which allows for automated section cuts and replication from pre-defined templates, accommodating variations including holes and rotations.

Engineering Contradiction Analysis
1Measurement precision
If manual dimensioning methods are used for complex cross sections, then measurement flexibility is maintained, but time consumption and error rate increase significantly
Solution Approach 1:
The patent replaces manual mechanical dimensioning operations with an automated computer-based system that processes cross-section images, extracts geometric features, and performs measurements automatically, eliminating human error and time consumption while maintaining measurement flexibility
Solution Approach 2:
The system enables self-service dimensioning by automatically processing cross-section images, identifying geometric features, and generating measurement results without requiring manual intervention, thereby reducing both time and errors
2Productivity
If automated dimensioning solutions are used for specific cross section shapes, then productivity increases, but adaptability to shape variations decreases
Solution Approach 1:
The patent creates a universal automated dimensioning system that can handle multiple cross-section shapes including those with holes and rotations by implementing shape-agnostic image processing algorithms that adapt to any geometric configuration
Solution Approach 2:
The system adapts to different cross-section shapes by dynamically adjusting processing parameters such as orientation angles, hole detection thresholds, and dimensioning references based on the actual geometric features detected in each cross-section image
3Productivity
If automated solutions are implemented for cross section dimensioning, then time efficiency improves, but complexity of the system increases
Solution Approach 1:
The patent divides the automated dimensioning system into modular functional components including image acquisition, preprocessing, feature extraction, measurement calculation, and result output modules, making the complex system manageable and maintainable while maintaining high processing speed

AI summary
A method is provided for defining a cross section having an arbitrary shape. The method includes creating a vector graphic of the cross section. The method includes disassembling the vector graphic of the cross section into paths that represent an outline of the arbitrary shape of the cross section, each path a straight path or a curved path having respective endpoints including a first endpoint and a second endpoint. The method includes arranging the paths in an order in which the paths are connected in the vector graphic to form the outline of the arbitrary shape of the cross section, and generating an array of elements for the paths, including elements for successive pairs of adjacent straight paths in the order in which the paths are arranged. And the method incudes defining and thereby producing a definition of the cross section from the array of elements.
