Pillow for performing roll maneuver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head maneuver exercises for BPPV patients require supervision and are prone to errors, making it difficult for patients to accurately perform roll maneuvers for treating Horizontal Canal Benign Paroxysmal Positional Vertigo (HC-BPPV) without professional guidance.
Innovation Solution
A pillow with contoured segments and instructions on its surface allows patients to perform the roll maneuver by positioning their head at various angles, facilitating the movement of debris in the inner ear through gravitational force, enabling self-directed treatment of HC-BPPV without professional supervision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional head maneuver exercises are performed without supervision, then patient independence and accessibility improve, but accuracy and reliability of the maneuver deteriorate
Solution Approach 1:
The pillow enables patients to perform the roll maneuver independently by providing built-in visual instructions and positioning guides directly on the pillow surface, eliminating the need for external supervision while ensuring accurate head positioning through self-guided placement on the contoured segments
Solution Approach 2:
The pillow incorporates visual feedback mechanisms through markings and instructions printed on its surface that guide patients on correct head placement and maneuver execution, allowing patients to self-correct their positioning to maintain maneuver accuracy without professional supervision
2Reliability
If professional supervision is provided for head maneuvers, then maneuver accuracy improves, but device complexity and resource requirements worsen
Solution Approach 1:
The pillow integrates all necessary guidance functions directly into the device itself through printed instructions and contoured segments, transforming a service-dependent process into a self-service system that maintains accuracy without requiring external professional resources
3Measurement precision
If multiple pillow segments are used for precise head positioning, then maneuver precision improves, but pillow complexity worsens
Solution Approach 1:
The pillow is divided into multiple contoured segments, each designed to support the head at a specific angle and position required for different phases of the roll maneuver, allowing precise head positioning through modular placement rather than complex mechanical adjustments
Solution Approach 2:
Each pillow segment features contoured surfaces with specific curvatures that naturally guide and secure the head at predetermined angles, using geometric shape rather than complex mechanical structures to achieve positioning precision
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
The pillow enables patients to accurately perform the roll maneuver over a 0-360 degree angle range, effectively moving debris towards the utricle, thereby treating HC-BPPV with reduced errors and increased accessibility.
Implementation Method 1
The second and fourth segments of the one or more segments are contoured to elevate a head position of a subject at various angles such as, for example, 25 degrees to cause the horizontal canal of the subject's inner ear to be vertical

AI summary
The present invention provides a pillow for performing roll maneuvers, wherein a subject performs the roll maneuver by following a set of instructions specified on the pillow. The pillow includes one or more segments that are sequentially arranged, wherein the pillow can be folded and unfolded at a central section along a vertical axis using a connecting element. Each segment of the one or more segments, with the set of instructions, is contoured on either side of a horizontal axis of the surface of the pillow. The set of instructions allows the subject to perform the roll maneuvers, which causes debris present in any position in the horizontal canal of the inner ear of the subject to move towards an utricle.
