Solution Overview

Problem

Existing compression garments for treating edema, such as lymphedema, suffer from user discomfort due to moisture and heat trapping, durability issues with foam particles, and limited flexibility in treatment modes.

Innovation Solution

A compression garment featuring a tubular padded sleeve with polyhedral foam particles between inner and outer layers, creating an irregular surface pattern for varied pressure distribution, combined with moisture-wicking and temperature-regulating fabrics, and configurable with oversleeves and undersleeves for adjustable compression profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If foam particles are used in compression garments, then compression therapy can be provided, but the foam particles deteriorate and compact over time

Engineering Contradiction:

Improvedurability of foam particlesVSAvoidservice life of compression garment

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent changes the physical parameters of the foam particles by controlling their density (2-3.5 pounds per cubic foot) and compression characteristics to maintain structural integrity and compression effectiveness over extended periods, preventing deterioration and compacting

Inventive Principle:

Principle #35Parameter changes

2Force

If padded foam sleeves are used, then compression can be applied, but moisture and heat are trapped causing user discomfort

Engineering Contradiction:

Improvecompression forceVSAvoidmoisture and heat trapping

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent employs porous foam particles with controlled porosity that allow moisture vapor transmission and heat dissipation while maintaining the necessary compression force, thereby reducing moisture and heat trapping and improving user comfort

Inventive Principle:

Principle #31Porous materials

3Stress or pressure

If uniform pressure is applied across the body part, then compression is effective, but the irregular surface pattern reduces contact area

Engineering Contradiction:

Improvecompression pressureVSAvoidcontact area between garment and body

Core Design Contradiction:

Stress or pressureVSArea of stationary object

Solution Approach 1:

The patent creates local variations in surface quality through the irregular arrangement of foam particles, which concentrates compression pressure at specific contact points while maintaining overall compression effectiveness through the distributed pattern of pressure application

Inventive Principle:

Principle #3Local quality

AI summary

The invention concerns a compression garment for providing compression to a body part, in particular a limb, of a patient, comprising an, in particular tubular, padded sleeve extending around the body part and havingan inner layer and an outer layer secured, in particular sewn, together to define at least one enclosure between them, andmultiple particles, in particular plastic foam particles, received in the enclosure for being pressed against the body part.
