Axillary Support Cushion Structure for Sidelying Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning on one's side while sleeping or under anesthesia increases pressure on shoulder and axillary structures, leading to pain, numbness, and altered sleep patterns, with existing support structures failing to alleviate this pressure effectively.
Innovation Solution
An axillary support device comprising a head cushion, a thoracic cushion, and a connector that creates a valley to receive the upper arm, providing support to maintain a neutral cervical spine alignment and relieve pressure on the axilla, with optional inflatable bladders and compressible foam-like materials for adjustable comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user sleeps in a sidelying position, then the user can sleep comfortably without back pain, but increased pressure is applied to the shoulder and axillary structures causing pain and nerve injury
Solution Approach 1:
A wedge-shaped support device is introduced as an intermediary element between the user's body and the mattress. This device redirects the body weight through the wedge structure, creating a decompression zone that relieves pressure on the axillary structures while maintaining the beneficial sidelying position for back comfort.
Solution Approach 2:
The solution moves from a two-dimensional flat mattress surface to a three-dimensional wedge-shaped structure. By adding vertical dimension and creating an inclined plane, the device redistributes pressure across different spatial dimensions, eliminating concentrated pressure points on the axilla while preserving lateral positioning.
2Object-affected harmful factors
If existing support structures are used, then some pressure relief is provided, but they fail to effectively alleviate pressure on the axilla and maintain neutral cervical alignment simultaneously
Solution Approach 1:
The support device is segmented into distinct functional zones: a wedge-shaped main body for axillary decompression, a head support portion for cervical alignment, and an arm support surface. This segmentation allows each zone to independently address specific anatomical requirements without requiring complex multi-component systems.
Solution Approach 2:
The wedge-shaped device serves multiple functions simultaneously: it provides axillary decompression through its inclined plane, supports the head and neck for cervical alignment, and offers arm support through its extended surface. This multi-functionality eliminates the need for separate devices for each function, reducing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively reduces stress on the axilla and associated structures, preventing injuries and maintaining comfortable sleep for individuals with shoulder and upper extremity conditions, while maintaining a neutral cervical spine alignment.
Implementation Method 1
An inflatable bladder may be provided in at least one of the head cushion and the thoracic cushion to enable adjustment of the volume of the fluid.
Implementation Method 2
The head cushion and/or the thoracic cushion may be formed from a compressible foam-like material.

AI summary
An axillary support device is provided for decompressing the axilla (armpit) and associated structures in a sidelying position. A thoracic cushion provides firm axillary support to a user at the level of the mid to upper thorax, distal to the axilla. A head cushion connected to the thoracic cushion supports the user's head and may maintain a neutral cervical spine alignment position. A connector connecting the cushions creates a valley to receive an upper arm of the user. A back support may be used to maintain the sidelying position. An inflatable bladder may be used to adjust the axillary support device in order to appropriately relieve pressure on the user's axilla and associated structures. With the axillary support device, the upper arm of the user is relatively free to extend perpendicularly in front of the body in the sidelying position with reduced stress on the lateral shoulder and axilla.
