Garment Design Using Bias-Wise Fabric Segmentation for Natural Body Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sartorial and industrial design methods result in garments that are rigid, uncomfortable, and limit movement due to the use of standardized mannequins and unidirectional fibers, leading to inadequate elasticity and strength, especially in areas like the buttocks and shoulders, and often require non-natural fibers to achieve some flexibility, which are harmful and polluting.
Innovation Solution
A design and manufacturing method that incorporates both main and secondary portions of fabric, with secondary portions arranged in a bias-wise configuration to accommodate areas of high deformation, using natural fibers and curved sewing lines to allow for three-dimensional fit and movement, eliminating the need for unidirectional fibers and reducing fabric stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If garments are made using standardized mannequins and unidirectional fibers (straight grain or all bias-wise), then manufacturing precision and ease of manufacture are improved, but the garment becomes rigid, uncomfortable, and limits user movement
Solution Approach 1:
The garment is divided into multiple fabric portions (first portion, second portion, third portion, fourth portion) with different fiber orientations. Each portion is cut in a specific grain direction (straight grain or bias-wise) to provide appropriate elasticity and support for different body areas, allowing movement while maintaining structure.
Solution Approach 2:
Different portions of the garment have different fiber orientations tailored to specific body areas. The first and second portions use one grain direction while the third and fourth portions use another, optimizing comfort and mobility for each local region of the body.
2Ease of operation
If elastic fibers (mainly derived from oil) are used to guarantee elasticity, then ease of operation is improved, but object-generated harmful factors worsen due to pollution and harm to people
Solution Approach 1:
The invention changes the material parameter from synthetic elastic fibers to natural fibers (cotton, wool, silk, linen). Elasticity is achieved not through material composition but through the geometric arrangement of fabric portions in different grain directions and their interconnection, providing environmental benefits while maintaining functionality.
3Adaptability or versatility
If seams are made at points where fabric portions have differently oriented fiber directions, then adaptability to body shape is improved, but manufacturing precision worsens due to irregular seams
Solution Approach 1:
The garment uses asymmetric seam placement and configuration. The first and second portions are connected at a first seam, while the third and fourth portions are connected at a second seam, with each seam positioned and oriented to accommodate the natural asymmetry of body contours while maintaining manufacturing feasibility.
4Ease of manufacture
If garments are cut all in straight grain or all bias-wise, then ease of manufacture is improved, but the garment becomes rigid and boxes, constraining natural movement
Solution Approach 1:
The garment is segmented into multiple fabric portions with different grain orientations. This segmentation allows different areas of the garment to have different flexibility characteristics, combining ease of manufacture with natural movement capability.
Solution Approach 2:
The invention uses bias-cut portions (cut at 45 degrees to the straight grain) in specific areas to introduce curvature and flexibility. The bias-cut fabric naturally drapes and conforms to body contours, reducing rigidity while maintaining structural integrity.

AI summary
A sartorial and/or industrial design is provided that is suitable for defining an item of clothing made exclusively from natural-type fibres for a user and including at least one main portion including fabric arranged in straight grain with respect to the body of the user and a secondary portion including a fabric arranged bias-wise with respect to the body of the user that is arranged in an area of the body subject to higher traction than the rest of the body and essentially shaped like at least part of the area of the body.
