Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression garments struggle to provide a predictable and controllable pressure profile for various body part sizes, making it difficult to achieve optimal compression therapy, especially for body parts with circular cross sections, due to the dependence on the shape and circumference of the body part.
Innovation Solution
A compression garment made from a single sheet of elastic material with predefined folding possibilities, featuring markings for intuitive and precise adjustment of pressure profiles, allowing for a range of pressure profiles to be easily obtained and applied, regardless of body size, using a material that maintains consistent pressure across different circumferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression garments are made in multiple sizes to accommodate different body part sizes, then pressure consistency across individuals is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The compression garment is designed as a universal one-size-fits-all product that can be adapted to different body part sizes through folding configurations. The garment includes predefined fold lines that allow users to create different folding patterns (e.g., single fold, double fold, triple fold) to adjust the compression level and accommodate various circumferences, eliminating the need for multiple size variants while maintaining pressure consistency across different individuals.
2Stress or pressure
If the compression garment circumference is varied in the longitudinal direction to create pressure gradients, then pressure distribution along the body part is improved, but manufacturing precision and design complexity increase
Solution Approach 1:
The garment is divided into multiple sections with predefined fold lines that segment the continuous fabric into controllable zones. Each section can be independently folded to create localized pressure variations along the longitudinal direction. The fold lines act as segmentation boundaries that allow precise control over where pressure gradients occur, simplifying manufacturing compared to continuously varying the circumference while achieving the same pressure distribution effect.
3Stress or pressure
If elastic properties are adjusted along the longitudinal direction to achieve pressure gradients, then pressure control is improved, but manufacturing complexity and material cost increase
Solution Approach 1:
Instead of varying the elastic properties of the material itself, the invention changes the geometric parameter (number of layers) through folding. The same uniform elastic material is used throughout, but by folding the garment one, two, or three times in different sections, the effective compression pressure is adjusted. This approach maintains ease of manufacture with uniform material while achieving precise pressure control through geometric transformation.
4Stress or pressure
If bands with hook and loop fasteners are used to control stretching and pressure, then pressure adjustability is improved, but device complexity and ease of operation decrease
Solution Approach 1:
Instead of using fasteners to prevent stretching, the invention inverts the approach by using folding to create controlled stretching. The garment is applied in an unfolded state for easy donning, then folded in place to create the desired compression. The folding mechanism naturally controls the stretching amount through the geometry of the fold, eliminating the need for complex fastening systems while improving ease of operation.

AI summary
A compression garment for providing an adjustable pressure towards a body part is disclosed. The compression garment comprises a unitary single sheet of elastic material arranged to encircle the full circumference of a body part, such as a limb or the head. The sheet is folded or arranged to be folded in at least one predefined way, so that the folding forms one or more defined overlap(s) forming at least two overlaying layers of the sheet encircling the full circumference of a part of the body part. Hereby, the pressure profile of the garment can easily be adjusted by making use of the garment in different folded configurations. Markings may further be provided to provide guidance towards the predefined ways of folding.
