Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In CAD systems, identifying and processing geometrically similar elements manually is difficult, time-consuming, and inefficient, leading to prolonged computing times and design iteration delays.
Innovation Solution
A method to automatically identify and label geometric clones by generating and comparing maps of candidate forms to a template, allowing for rapid determination and grouping of similar elements for simultaneous processing.

Engineering Contradiction Analysis
1Productivity
If manual identification and processing of geometrically similar elements is used, then processing accuracy can be maintained, but processing time and design iteration delays increase significantly
Solution Approach 1:
The patent replaces manual mechanical identification processes with an automated computer-based system that uses map generation and comparison algorithms to identify geometric clones, thereby eliminating the time-consuming manual inspection while maintaining accurate identification
Solution Approach 2:
The system transforms geometric forms into map representations with specific parameters (nodes, edges, faces) that can be automatically compared and matched, enabling rapid identification of geometric clones through parameter comparison rather than manual visual inspection
2Productivity
If automated map generation and comparison is implemented, then processing efficiency increases, but system complexity increases
Solution Approach 1:
The patent divides the complex geometric identification task into manageable segments: generating maps for individual geometric forms, storing them in a library, and comparing candidate maps against template maps, making the automated process more tractable and implementable

AI summary
Methods for identifying geometric clones in a modelling system, or simulating modifications to construction of a multi-part product and corresponding data processing systems and computer readable media. A method includes choosing a template of a geometric form and generating and storing a map of the template, identifying a candidate geometric form in the system and exploring the identified candidate geometric form from a start point until returning to the start point or reaching a branch. The method includes generating a map of the explored candidate geometric form, comparing the map of the explored candidate geometric form with the map of the template and labelling the candidate geometric form as a clone if it matches a predetermined portion of the template.
