Compression Wrap Sleeve for One-Handed Donning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression devices for treating conditions like tennis elbow are difficult for individuals to apply alone, as they require leveraging against the body or assistance from another person.
Innovation Solution
A compression wrap design featuring a stretchable layer straddling a compression pad, forming a sleeve that allows easy donning without needing to pincher the strap, with a fastening tab and loop for secure tightening, enabling one-handed application and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional wrap device is used to provide compression therapy, then therapeutic pressure can be applied to the limb, but the device becomes difficult for a person to apply with a single hand
Solution Approach 1:
The wrap device is divided into distinct functional segments: a compression pad portion for therapeutic pressure, a stretchable layer for forming the sleeve, and a fastening mechanism. This segmentation allows each component to perform its specific function independently, making the overall device easier to don while maintaining therapeutic effectiveness.
Solution Approach 2:
The compression pad is disposed within the elongated wrap body, and the stretchable layer is coupled to the wrap body to form a nested sleeve structure. This nesting allows the compression pad to be integrated into the wrap while the stretchable layer provides the donning mechanism, reducing the need for complex external structures.
2Ease of operation
If a stretchable layer is added to form a sleeve for easy donning, then the device becomes easier to apply alone, but the device complexity increases
Solution Approach 1:
The stretchable layer is merged with the compression pad and wrap body to form an integrated sleeve structure. This combining of components achieves the dual benefit of easy donning through the sleeve while avoiding the need for separate donning aids, thereby limiting the increase in device complexity.
Solution Approach 2:
The stretchable layer serves multiple functions: it forms the sleeve for easy donning, provides additional compression when stretched, and integrates with the fastening mechanism. This multi-functionality reduces the need for separate components, balancing ease of operation with device complexity.
3Reliability
If the wrap device is designed to be secured with fastening mechanisms, then therapeutic pressure is maintained, but the device becomes more complex to apply
Solution Approach 1:
The fastening mechanism is designed to be self-applied by the user without requiring assistance from another person. The tab and loop configuration allows the user to easily secure the wrap themselves, maintaining compression stability while preserving ease of operation for single-handed application.

Function Achieved in This Case
Enables users to apply therapeutic pressure to the limb independently, reducing the effort required for donning and providing effective compression therapy without assistance.
Implementation Method 1
a stretchable layer straddles the compression pad with a first end coupled to the elongated wrap member to one side of the compression pad and another end coupled to the elongated wrap member to another side of the compression pad

AI summary
A compression wrap (100) includes an elongated wrap body (101) extending from a first end (102) to a distal end (103). A fastening tab (116) is coupled to a first major face (205) of the elongated wrap body at the first end. A fastening loop (118) is coupled to the first major face of the elongated wrap body at the distal end. A compression pad (106) is disposed along a second major face (105) of the elongated wrap body between the first end and the distal end. A stretchable layer (108) straddles the compression pad such that the stretchable layer and a portion (208) of the elongated wrap body comprising the compression pad define a stretchable sleeve (303).
