Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compression garments require multiple fabric panels with different compression intensities and appearances, leading to aesthetic and comfort issues, high production costs, and limitations in textile processes like dyeing and laser treatment.
Innovation Solution
A compression garment made of a single layer of woven stretchable fabric with uniform elasticity, featuring varying circumferential compression along different axial locations without separate panels, achieved through geometric cuts and seams that extend the entire length of the garment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fabric panels with different compression intensities are used to provide different levels of compression at different locations, then the compression effectiveness is improved, but the device complexity and production cost increase due to multiple panels and seams
Solution Approach 1:
The patent applies local quality by creating different compression intensities at different axial locations within a single continuous fabric panel. The fabric is engineered with spatially varying mechanical properties through its construction (e.g., varying knit density, yarn composition, or structural characteristics across the fabric surface), allowing each region to provide appropriate compression force locally without requiring separate panels or seams.
Solution Approach 2:
The patent changes physical parameters of the fabric itself to achieve varying compression levels. By modifying fabric construction parameters such as knit gauge, yarn elasticity, thread density, or structural pattern at different locations, the fabric provides different compression intensities while remaining a single continuous piece, thereby avoiding the need for multiple panels joined by seams.
2Reliability
If multiple fabric panels with different appearances are joined together to create different compression levels, then the compression functionality is improved, but the aesthetic appearance deteriorates due to visible seams and panel boundaries
Solution Approach 1:
The fabric is designed with local quality variations in its mechanical properties while maintaining visual uniformity. Different regions of the single fabric panel have different compression characteristics achieved through subtle construction variations that are not visually apparent, allowing the garment to provide differentiated compression functionality without compromising aesthetic appearance or creating visible seams.
3Adaptability or versatility
If multiple fabric panels are joined together to provide different compression levels, then the compression versatility is improved, but the ease of manufacture deteriorates due to complex assembly processes
Solution Approach 1:
The patent merges the functions of multiple separate fabric panels into a single continuous fabric construction. By integrating different compression zones within one unified fabric piece, the design eliminates the need for complex assembly processes involving cutting, aligning, and joining multiple panels, thereby significantly simplifying manufacturing while maintaining compression versatility.
Solution Approach 2:
The single fabric panel is designed to perform multiple compression functions simultaneously. Different regions of the fabric provide different compression levels for various body parts or areas, making the single fabric piece universally functional for providing differentiated compression therapy without requiring separate specialized panels for each function.
4Ease of manufacture
If conventional knitting technology is used to manufacture compression garments, then the ease of manufacture is improved, but the adaptability to textile processes deteriorates due to limitations in dyeing and washing
Solution Approach 1:
The patent replaces traditional knitting technology with weaving technology for manufacturing the compression fabric. This substitution enables the fabric to be manufactured in a way that is compatible with conventional textile processes such as dyeing, washing, and finishing operations. The woven structure provides the necessary mechanical properties for compression while being more adaptable to standard textile manufacturing workflows.

AI summary
The disclosure provides a compression garment (68) formed of a stretchable fabric (10) with a uniform, i.e. constant, elasticity but in which the compression garment provides different degrees of garment compression when worn by a wearer due to geometric cuts (6, 8) made to the fabric to form one or more fabric panels (2, 4) that extend the entire length of the circumferential portion (60) of the garment. The circumferential portion surrounds a wearer's body part (66) and includes degrees of compression that vary at different locations (12, 14, 16, 18, 20, 22, 24, 26), along the axial direction (62). The geometric cuts produce non-linear edges (6A, 6B, 8A, 8B) and are made to provide different circumferential lengths (12F, 14F, 16F, 18F, 20F, 22F, 24F, 26F) of fabric that produce desired compression levels at various axial locations, and are calculated using formulas and algorithms that take into account various factors relating to the fabric and the garment being formed.
