Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compression garments, particularly those produced through knitting technology, face limitations such as uneven compression levels, aesthetic issues, and high production costs due to the use of multiple fabric panels and seams, making them unsuitable for everyday fashion wear.
Innovation Solution
A compression garment design utilizing a single fabric panel with varying degrees of stretch at different axial locations to achieve uniform compression, manufactured by cutting and joining panels to form a circumferential portion with specific geometric patterns, ensuring consistent compression across the garment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple fabric panels with different elasticities are used to achieve uniform compression, then compression uniformity is improved, but device complexity and production cost increase
Solution Approach 1:
The patent applies local quality by varying the elasticity properties at different axial locations of the garment while using a single continuous fabric panel. The fabric is engineered with spatially varying elastic modulus or fiber composition, allowing each region to provide the appropriate local compliance needed for uniform compression without requiring multiple separate panels with different material properties.
Solution Approach 2:
The patent changes physical parameters of the fabric, specifically the elasticity modulus or stretch characteristics, as a function of axial position. By continuously varying the elastic properties along the length of the garment, the design achieves uniform compression force distribution while maintaining a simple single-panel construction, avoiding the complexity of assembling multiple panels with different material properties.
2Manufacturing precision
If multiple fabric panels are used to achieve uniform compression, then compression uniformity is improved, but production cost increases
Solution Approach 1:
The patent merges the functions of multiple fabric panels with different elasticities into a single integrated fabric panel. This consolidation eliminates the need for separate manufacturing of multiple panels and their subsequent assembly, reducing production complexity and cost while achieving the same uniform compression effect through spatially varying material properties within the single panel.
Solution Approach 2:
By continuously varying the elastic parameters within a single fabric panel rather than using discrete panels with different properties, the manufacturing process is simplified. This approach reduces material waste, eliminates complex cutting and sewing operations for multiple panels, and lowers production costs while maintaining compression uniformity.
3Manufacturing precision
If multiple fabric panels with seams are used, then compression uniformity is improved, but aesthetic appearance and comfort deteriorate
Solution Approach 1:
The patent merges multiple fabric panels into a single continuous panel, eliminating seams that would otherwise be visible and potentially uncomfortable. This seamless construction improves aesthetic appearance by providing a smooth, uniform surface and enhances comfort by removing potential irritation points from seam edges and bulk, while still achieving uniform compression through varying fabric elasticity.
Solution Approach 2:
The patent achieves compression uniformity through local variations in fabric elasticity rather than through multiple panels with seams. This approach maintains a smooth, seamless appearance that is aesthetically pleasing and comfortable for the wearer, while the localized changes in material properties ensure uniform compression distribution across different body regions.

AI summary
Provided is a compression garment (68) formed of a stretchable woven fabric (10) with a uniform elasticity, such as denim. A circumferential portion (60) of the garment surrounds a wearer's body part (66) and is characterized by different degree of stretching but the same circumferential compressive forces when worn by a wearer, at various axial locations (12, 14, 16, 18, 20, 22, 24, 26) due to geometric cuts (6, 8) made to the fabric to form one or more fabric panels (2, 4), each of which extend along the entire length of the circumferential portion (60). The compressive forces, degrees of stretching and circumferential lengths (12C, 14C, 16C, 18C, 20C, 22C, 24C, 26C) of fabric, are calculated using formulas and algorithms that take into account various factors relating to the fabric and the garment being formed.
