Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D clothing draping simulations require user input for pattern arrangement and sewing, which can lead to intersections and errors, and lack efficient automation in generating 3D clothing from 2D patterns.
Innovation Solution
A method and apparatus that group 2D clothing patterns by type, provide sewing information as a database, and automatically sew patterns together using pattern blocks with embedded sewing information, reducing user input and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pattern arrangement and sewing is used, then user control over clothing design is maintained, but the process is time-consuming and prone to errors
Solution Approach 1:
The system enables self-service by allowing the 3D clothing generation system to automatically arrange patterns, determine sewing lines, and generate clothing models without requiring manual user intervention for each step, thereby improving productivity while maintaining ease of operation through automated decision-making algorithms
Solution Approach 2:
The system applies preliminary action by pre-defining pattern blocks with embedded sewing information and arranging them in advance according to clothing type classifications, so that when generation is needed, the system can quickly assemble final clothing designs without time-consuming manual arrangement
2Reliability
If manual pattern arrangement is used, then flexibility in design is maintained, but intersections and errors occur between patterns and avatar
Solution Approach 1:
The system implements feedback by automatically detecting intersections between patterns and avatar, then adjusting pattern positions and sewing lines based on this feedback to eliminate errors, ensuring reliable pattern arrangement without increasing operational complexity
Solution Approach 2:
The system uses an intermediary approach by introducing automated pattern recognition algorithms that act as mediators between the user's design intent and the final pattern arrangement, analyzing pattern shapes and automatically matching them to appropriate positions on the avatar to prevent intersections
3Extent of automation
If automated pattern matching is implemented, then user input time is reduced, but automation extent increases
Solution Approach 1:
The system applies segmentation by dividing the automated pattern sewing process into distinct modules: pattern recognition, matching, sewing line determination, and execution. This modular segmentation enables high automation while managing system complexity through organized, independent functional blocks that can be developed and maintained separately

AI summary
When producing a piece of three-dimensional (3D) clothing through a computer simulation, a 3D clothing draping simulation method includes inputting a two-dimensional (2D) clothing pattern, inputting a pattern block, matching the input 2D clothing pattern to the input pattern block, converting the matched 2D clothing pattern and pattern block into a database (DB), selecting a pattern block which is matched with 2D clothing pattern from the pattern block database, and automatically sewing 2D clothing patterns matched with selected pattern blocks together according to sewing information of the pattern blocks.
