Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D clothing draping simulation methods face instability and tangling issues when folding and sewing patterns, leading to inconvenient and difficult-to-resolve collisions and intersections.
Innovation Solution
A 3D clothing draping simulation method that includes designating sewing lines, inputting sublayer relations, and applying layer limitations between patterns to prevent collisions, using a user interface tool that sets layers based on sewing lines, extracts meshes as line segments, and connects lattice points with springs to manage pattern overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If patterns are folded using a folding function or meshes are reset, then folding and sewing operations can be performed, but patterns collide and intersect causing simulation instability
Solution Approach 1:
The pattern is divided into multiple layers with different z-order values. By segmenting the pattern into layers, the system can control which parts are visible and which are hidden, preventing unwanted collisions and intersections while maintaining folding and sewing operations.
Solution Approach 2:
The patent introduces a new dimension (z-order or layer depth) to manage pattern overlaps. Instead of handling collisions in 2D space, the system uses the third dimension to establish visibility rules, where patterns in different layers do not collide even when their projections overlap in 2D space.
2Ease of manufacture
If strip patterns are sewn on clothing without layer management, then sewing operations can be performed, but patterns become tangled and intersect
Solution Approach 1:
The pattern elements are segmented into distinct layers with assigned z-order values. This segmentation allows the system to track and manage the spatial relationship between different pattern parts, preventing tangling and maintaining proper shape during sewing operations.
Solution Approach 2:
The system performs preliminary layer assignment and z-order configuration before sewing operations. By pre-establishing the layer hierarchy and visibility rules, the system prevents pattern tangling and intersection issues from occurring during the sewing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents pattern collisions and tangling by applying virtual forces between layers, ensuring stable and accurate draping simulations, thereby simplifying the 3D clothing making process.
Implementation Method 1
connecting lattice points of meshes including the first line as line segments and vertices of meshes including the second line as line segments by a spring
Implementation Method 2
a layer limitation is applied on a portion of a pattern including the first line and the second line so that the first line and the second line which have received the sublayer relation are layered with each other

AI summary
The present disclosure relates to a method of applying a sublayer in which a layer is applied on the basis of a sewing line as a unit and an apparatus thereof in making 3D clothing by computer simulation. A partial region within a pattern is designated by selecting a sewing line through a user interface, and a sublayer in which a layer is set on the basis of the sewing line is set.
