3D Model Division for Workpiece and Jig Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional model creation techniques require separate image capturing and modeling of workpieces and jigs each time machining occurs, leading to inefficiencies and inability to distinguish between the two during interference checks.
Innovation Solution
A device that captures images or measures both workpieces and jigs together, then divides and tags the integrated three-dimensional model into individual models of the workpiece and jig using a three-dimensional model division processing unit, user interface, and individual model creating unit, allowing for efficient creation of separate models with minimal operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate three-dimensional models of workpiece and jig are created using conventional techniques, then interference check accuracy is improved, but operator effort and time consumption increase significantly
Solution Approach 1:
The patent merges the workpiece and jig into a single integrated three-dimensional model captured in one image, eliminating the need to create separate models. The integration unit combines the workpiece model and jig model into an integrated model that can be processed for interference checks, significantly reducing operator effort while maintaining check accuracy.
Solution Approach 2:
The patent segments the integrated three-dimensional model into distinct workpiece and jig components through automatic recognition. The integration unit separates the captured image data into individual component models based on geometric features and attachment relationships, enabling separate interference analysis without requiring separate capture processes.
2Ease of manufacture
If integrated three-dimensional model of workpiece and jig is created, then model creation effort is reduced, but ability to distinguish and check components separately is lost
Solution Approach 1:
The integration unit automatically segments the integrated three-dimensional model into distinct workpiece and jig components by analyzing geometric features, attachment interfaces, and spatial relationships. This segmentation preserves component identity and enables separate interference checks while maintaining the efficiency of single-capture integrated modeling.
Solution Approach 2:
The patent introduces an integration unit as an intermediary that maintains both the integrated model and segmented component models. This intermediary structure allows the system to work with either the integrated model for overall positioning or the segmented components for detailed interference analysis, preventing information loss.
3Measurement precision
If multiple images are captured to create separate models of workpiece and jig, then model accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent combines multiple capture functions into a single image capture operation. The integration unit processes the captured image to extract both workpiece and jig geometric information simultaneously, achieving accurate separate models without requiring multiple separate capture operations or complex multi-step procedures.

AI summary
A three-dimensional model creating device creates an individual model indicating an individual shape of an object from an integrated model created based on data obtained by capturing images of or measuring at least two or more objects together. The three-dimensional model creating device includes: a three-dimensional model division processing unit configured to create a plurality of divided models obtained by dividing the integrated model by an extension plane extended from each plane configured to form the integrated model; a user interface unit configured to receive tagging of each of the divided models; and an individual model creating unit configured to create the individual model of the object based on the tagging of each of the divided models.
