Compression Sleeve Notch Structure for Easier Donning and Doffing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression garments are difficult to don and doff due to their snug fit, especially when designed for specific body parts like wrists or ankles, and lack features that facilitate easy adjustment and fitting over varying limb sizes.
Innovation Solution
A compression garment with a notch and elastic stretch panel loop that allows for easy expansion and contraction, enabling easier fitting and removal, and can be combined with additional compression garments for enhanced adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the compression garment is designed with a snug fit for specific body parts, then the compression effectiveness is improved, but the ease of donning and doffing deteriorates
Solution Approach 1:
The garment is divided into multiple segments including a first portion for the wrist/ankle, a second portion for the hand/foot, and a transition portion connecting them. This segmentation allows each section to be optimized independently - the first portion can be snug for compression while the transition portion provides gradual expansion to facilitate easy donning and doffing
Solution Approach 2:
The transition portion is designed with dynamic properties that allow it to expand and contract during donning and doffing operations. The gradual change in circumference from the first portion to the second portion creates a dynamic structure that accommodates the movement of the limb during garment application and removal, making the process easier while maintaining compression effectiveness
2Manufacturing precision
If the compression garment is designed for a specific body part size, then the compression precision is improved, but the adaptability to varying limb sizes deteriorates
Solution Approach 1:
Different portions of the garment have different structural qualities optimized for their specific functions. The first portion has a snug fit for precise compression, the transition portion has a gradual expansion for adaptability, and the second portion accommodates the hand or foot. This local differentiation allows the garment to adapt to varying limb sizes while maintaining compression precision where needed
Solution Approach 2:
The garment utilizes changes in physical parameters along its length, particularly in the transition portion where the circumference gradually changes. This parameter variation allows the garment to accommodate different limb sizes - the transition portion can stretch and expand to fit larger or smaller limbs while the first portion maintains consistent compression precision

AI summary
A chip sleeve garment including an outer layer of fabric connected to an inner layer of fabric to form a sleeve with a space between the outer layer of fabric and the inner layer of fabric. Foam chips, flat foam, or foam with ridges are disposed in the space between the outer layer of fabric and the inner layer of fabric. The garment includes two ends, including at least one open end, and a notch in at least one open end having an opening. The notch can be separated to create a larger opening than the opening to allow the garment to be donned or doffed easier than the opening allows. A second garment can be disposed over the chip sleeve garment. Either the chip sleeve garment, the second garment, or both can be compression garments.
