Compression Sleeve Stay-Up Device for Position Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compression garments tend to loosen or slide down the body during movement, leading to misalignment of inflatable bladders and ineffective compression therapy, causing discomfort and reduced efficacy.
Innovation Solution
A compression garment with a stay-up device that includes a first and second region and a leg portion extending between them, with the second region engaging the wearer's body to provide structural support, ensuring the garment remains in a fixed location and maintains effective compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the compression garment is made without a stay-up device, then the garment structure is simpler and easier to manufacture, but the garment tends to loosen and slide down the body part during movement
Solution Approach 1:
The compression garment is divided into functional segments: a compression section with inflatable bladders and a separate stay-up device with engagement features. This segmentation allows the compression function and position retention function to be independently optimized while working together as a unified system.
Solution Approach 2:
The stay-up device acts as an intermediary element between the compression garment and the body part. It includes engagement features that interface with anatomical landmarks (such as the calf muscle) to provide a mechanical anchor point, preventing the garment from sliding down during movement.
2Reliability
If the compression garment includes a stay-up device, then the position retention is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The stay-up device provides localized structural support at specific anatomical locations (such as the calf section) rather than requiring complex reinforcement throughout the entire garment. The engagement features are concentrated at key points where anatomical landmarks provide natural anchor points.
Solution Approach 2:
The stay-up device utilizes changes in anatomical parameters (such as the contour and prominence of the calf muscle) to achieve position retention. The engagement features are designed to interface with these anatomical variations, allowing the garment to adapt to different body shapes without requiring complex adjustable mechanisms.
3Stability of the object's composition
If the compression garment uses a stay-up device with engagement features, then the garment remains in fixed location during movement, but the device structure becomes more complex
Solution Approach 1:
Instead of trying to prevent the garment from moving down through complex elastic or mechanical retention systems, the invention inverts the approach by using the body's own anatomy (prominent calf muscle) as the retention mechanism. The stay-up device engages with the body part to prevent downward movement, rather than relying on garment elasticity alone.

AI summary
A compression garment having first and second sections includes a stay up device for supporting the compression garment in position on the body. The stay up device is constructed to operatively engage a portion of the body to positively locate the stay up device, and thereby the garment relative to the body.
