3D Modeling Support Layout Using Integrated Cutting Margins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designers face challenges in arranging and removing support members from three-dimensional products during the manufacturing process, as it is a cumbersome task to separate them from the product after cutting.
Innovation Solution
A data generation program and system that generates three-dimensional modeling data, including support members connected to the product, where the support members are integrated with a cutting margin, allowing them to be removed together with the cutting margin, thereby simplifying the process and eliminating the need for separate removal steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support members are arranged separately from the three-dimensional product, then the support members can regulate the position of the product during modeling, but it becomes a cumbersome task for the designer to arrange and remove the support members separately
Solution Approach 1:
The patent merges the support member with the cutting margin by connecting them together, so that the support member becomes an integrated part of the cutting margin structure. This allows the support member to maintain its position regulation function while eliminating the need for separate arrangement and removal operations, as both are handled together during the cutting process
2Ease of operation
If support members are integrated with the cutting margin, then the removal process is simplified, but the cutting margin thickness increases
Solution Approach 1:
The patent applies local quality by connecting the support member to only one specific side of the cutting margin rather than integrating it throughout the entire cutting margin structure. This localized connection approach simplifies the removal process while minimizing the increase in overall cutting margin thickness, as the support member is attached only where necessary
3Productivity
If the support member is removed together with the cutting margin, then separate removal steps are eliminated, but the cutting apparatus must be configured to remove both components
Solution Approach 1:
The patent applies universality by designing the cutting apparatus to perform multiple functions: it cuts the three-dimensional product and removes both the cutting margin and support member in a single operation. This multi-functional capability eliminates the need for separate removal steps and additional apparatus configurations, as the cutting apparatus is designed to handle all removal tasks uniformly

AI summary
A data generation program includes instructions of: acquiring three-dimensional data representing a three-dimensional shape of a three-dimensional product; acquiring an arrangement condition for arranging a support member to the three-dimensional product; setting an extending direction, a width direction, and a height direction of the support member; adding a cutting margin of a particular thickness to a cutting surface of the three-dimensional product at one side in the height direction; setting the support member in accordance with the arrangement condition, one end of the support member in the extending direction being connected to the cutting margin added to the three-dimensional product; setting a beam, the beam being spaced from the three-dimensional product having the cutting margin in the extending direction, the beam extending in the width direction; generating three-dimensional modeling data for modeling a modeled object by using a three-dimensional modeling apparatus; and outputting the three-dimensional modeling data.
