Apparel Design Extrapolation Preserving Aspect Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating custom designs on apparel fail to maintain the aspect ratio and integrity of full-bleed designs across varying sizes and product types, requiring manual redesign for each size due to significant horizontal growth and curvature variations.
Innovation Solution
The method employs specific scaling and translation formulas to automate design extrapolation across different sizes and product types, preserving the aspect ratio and adjusting elements to fit new patterns, utilizing formulas like [Sx=max (dX, dY), Sy=max (dX, dY), Tx=cX, Ty=cY] for scaling up and [Sx=min (dX, dY), Sy=min (dX, dY), Tx=cX, Ty=cY] for scaling down, and individual modifications for each design element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct scaling of image is used to adapt design to different sizes, then the design can be applied to various sizes, but the aspect ratio is lost and the image looks distorted
Solution Approach 1:
The design image is segmented into multiple pattern pieces corresponding to different apparel sizes. Each pattern piece is individually mapped and transformed based on its specific geometric characteristics, allowing the design to adapt to size variations while preserving the aspect ratio and visual integrity of each segment.
2Manufacturing precision
If manual design creation is performed for each size, then the aspect ratio and design integrity are maintained, but the time and effort required increases significantly
Solution Approach 1:
The system creates automated copies of the original design across multiple size variants. By establishing a mapping relationship between the source design and target pattern pieces, the system generates size-specific designs through automated transformation rather than manual recreation, significantly reducing time while maintaining quality.
Solution Approach 2:
The system transforms the design by changing geometric parameters (scaling factors, translation vectors, rotation angles) based on the target size requirements. These parameter adjustments are calculated automatically to preserve aspect ratios and ensure proper fit across different apparel sizes without requiring manual redesign.
3Ease of manufacture
If uniform scaling is applied to the design, then the application process is simplified, but the design elements may be cut off or distorted due to varying curvature across sizes
Solution Approach 1:
Instead of applying uniform scaling to the entire design, the system applies local quality transformations to different regions. Each pattern piece receives customized transformation parameters (scaling, translation, rotation) tailored to its specific geometric properties and curvature characteristics, ensuring that design elements remain complete and undistorted across varying sizes.

AI summary
A method for modifying the dimensions of a design pattern embedded on a garment is disclosed. Original dimensions of the apparel and new dimensions according to which the apparel is to be modified are determined. A coordinate pair indicating the center point of the design pattern is determined. Two delta factors, one corresponding to height and the other corresponding to the width are determined. The delta factors indicate the difference, in terms of height and width respectively, between the original dimensions of the garment, and the dimensions to which the garment is purported to be modified. Subsequently, one of the delta factors is selected depending upon the nature of modification, and provided as an input to an affine transformation operation, along with the coordinate pair. The dimensions of the design pattern are modified based on the affine transformation operation and the selected delta factor and coordinate pair.
