UV Mapping for Seamless Artwork Wrapping on 3D Garments

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional methods for applying artwork designs to clothing articles often result in distorted or disjointed images due to the 3D shape of the fabric, especially when applied after sewing, and can be out of alignment due to manufacturing errors, leading to incomplete or irregular wraps around the garment.

Innovation Solution

A network device with modules for generating and aggregating 2D design documents, including non-aggregated texture islands, to create a final aggregated texture image that can be scaled and applied to fabric patterns, ensuring continuous wrapping and alignment across seams and curves of the clothing article.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If artwork designs are applied to fabric after sewing patterns together, then the artwork can be applied to the finished garment, but the image becomes distorted or disjointed due to the 3D shape of the fabric and manufacturing errors

Engineering Contradiction:

Improveease of applying artworkVSAvoidalignment precision of artwork

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by creating a 3D model of the garment and generating a UV map before artwork application. This allows the artwork to be mapped onto the 3D surface in advance, accounting for the garment's shape and seams, thereby preventing distortion and misalignment when the artwork is transferred to the finished garment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a UV map as an intermediary between the 2D artwork and the 3D garment surface. The UV map serves as a coordinate system that bridges the flat artwork design and the curved 3D garment, enabling accurate placement and wrapping of artwork around seams and curves without distortion.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a single large sheet of heat transfer paper is used to print artwork across multiple pattern areas, then continuous wrapping can be achieved, but the paper size and handling complexity increase

Engineering Contradiction:

Improvecontinuity of artwork wrappingVSAvoidcomplexity of handling large heat transfer paper

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent segments the UV map into multiple coordinate regions corresponding to different garment panels (front, back, sleeves, etc.). This segmentation allows the artwork to be divided into manageable sections that can be printed on smaller heat transfer paper sheets, while the UV mapping ensures these segments align continuously when applied to the 3D garment surface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from 2D paper space to 3D garment space through UV mapping. By working in the UV coordinate system (another dimension), the system can wrap artwork continuously around the 3D garment surface even when the source artwork is divided into multiple 2D sections, effectively solving the continuity problem without requiring a single oversized paper sheet.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Device complexity

If standard UV mapping is used for 3D models, then the mapping process is simple, but seams and curves of the garment cause distortion and misalignment of the artwork

Engineering Contradiction:

Improvesimplicity of UV mapping processVSAvoidalignment of artwork across seams

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating separate UV map coordinate systems for different regions of the garment (front panels, back panels, sleeves, collar). Each region has its own optimized UV coordinates that account for local geometry and seam locations, ensuring artwork aligns correctly across seams while maintaining overall continuity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent accounts for the curved 3D surface of the garment by using UV mapping that wraps around the 3D model. This curvature-aware mapping ensures artwork follows the contours of the garment surface and aligns properly across seams, rather than appearing flat or distorted.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A network device including document, design, aggregation and production texture modules. The document module generates a 2D design document that includes non-aggregated texture islands (NTIs). Each of the NTIs corresponds to a pattern of a product. The NTIs include at least two versions of one of the NTIs. The design module adds an artwork image across at least two of the NTIs. The aggregation module aggregates the at least two versions of the NTIs and generates a final aggregated texture image based on the 2D design document. The final aggregated texture image includes final aggregated texture islands (FATIs). Each of the FATIs is distinctive from the other ones of the FATIs. The production texture module, based on the final aggregated texture image, generates a production texture that includes islands, which are scaled to match an actual size of a respective pattern to be transferred on fabric for the product.
