UV Unwrapping for Apparel Manufacturing Pattern Generation

Solution Overview

Problem

Current methods for generating manufacturing patterns from 3D designs do not accurately capture free-form designs spanning seams, leading to inconsistencies in the final product, and lack automation for ensuring design precision in apparel and accessory manufacturing.

Innovation Solution

The method involves creating a UV map that exactly matches the manufacturing pattern's shape and size, allowing for precise placement of design components and using UV unwrapping or image cutting techniques to generate patterns with exact art and text on each component, enabling accurate reproduction of user designs onto apparel or accessories.

Engineering Contradictions & Design Principles

Solution Approach 1:

The patent inverts the traditional UV generation approach by using UV unwrapping instead of UV projection. Instead of projecting a 3D model to create a UV map, the system unwraps the UV map to generate manufacturing patterns, thereby preserving design accuracy across seams while maintaining automation.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system creates a digital copy of the 3D model with embedded UV mapping information, then uses this copy to generate accurate manufacturing patterns through unwrapping. This copying process preserves the exact design geometry and seam locations, ensuring manufacturing precision while enabling automation.

AI summary

This invention is a method for automating the generation of manufacturing patterns for apparel and accessories directly from designs created on a 3-dimensional (3D) model. This differs from existing models in which users design “2D slices” of a 3D image created at various pre-defined angles. This invention includes the steps of: 1) Making the UV map of the 3D model exactly match the manufacturing pattern in shape and scale; 2) Positioning the various components in the UV map to facilitate the desired image or text flow; and 3) Using a UV unwrap method to produce the manufacturing patterns with the exact art and text on each component. Images and text are thereby allowed to span across seams and be accurately manufactured. Automation of this process ensures that the images and text on the manufacturing patterns are the exact same as that which the user designed.
