Adjustable Head-Rest Pillow Structure for BPPV Sleep Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Benign Paroxysmal Positional Vertigo (BPPV) are inadequate in preventing and mitigating symptoms, as conventional head maneuver exercises are not designed for preventive purposes, often uncomfortable, and fail to maintain effective head positioning during sleep, leading to unpredictable dizziness episodes and discomfort.
Innovation Solution
A head-rest device that allows adjustable inclination of the head between 10° to 60° relative to the horizontal, enabling users to sleep comfortably on their side or back, with adjustable layers and fastening mechanisms to maintain optimal angles for prolonged periods, mimicking some head maneuvering exercises and preventing otoliths from entering the semicircular canals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional head maneuver exercises are performed, then BPPV symptoms may be temporarily relieved, but the exercises are not designed for preventive purposes and do not maintain effective head positioning during sleep
Solution Approach 1:
The head rest device is configured in advance with specific inclination angles (10°-60°) to prevent otoliths from entering semicircular canals before dizziness episodes occur. The device maintains this predetermined positioning throughout sleep, providing continuous preventive action rather than reactive treatment.
Solution Approach 2:
The device provides continuous head positioning support throughout the entire sleep period (8-10 hours), ensuring uninterrupted maintenance of therapeutic angles. This continuous action prevents episodes that might occur during horizontal positioning, unlike discrete exercise sessions.
2Temperature
If the head is elevated on stacked pillows, then the head position may be elevated, but this induces large strain to the neck, spine and hip regions causing pain and discomfort
Solution Approach 1:
The head rest device provides localized support specifically at the head and upper back region, concentrating the elevation function where needed while leaving the rest of the body in a neutral, comfortable position. This localized approach achieves head elevation without forcing the entire spine into an awkward configuration.
Solution Approach 2:
The device allows dynamic adjustment of the inclination angle within the 10°-60° range, enabling users to optimize the angle for both symptom prevention and comfort. This dynamic capability replaces the static, fixed-angle approach of stacked pillows.
3Temperature
If wedge pillows are used, then the head can be elevated, but the user cannot position the head in more than one orientation
Solution Approach 1:
The head rest device incorporates adjustable components that allow users to modify both the inclination angle (10°-60°) and the orientation of head support. This dynamic adjustability enables the same device to accommodate different sleeping positions and individual anatomical variations.
Solution Approach 2:
The device is designed to serve multiple functions: it can elevate the head at various angles, support different head orientations, and accommodate different sleeping positions. This multi-functionality replaces the single-purpose wedge pillow.
4Ease of manufacture
If generic pillows are used, then they are available for all users, but people of different physical builds must go through different pillows to find the one that fits their physical builds
Solution Approach 1:
The device features adjustable components including removable bolsters, adjustable headrests, and variable inclination mechanisms that allow customization for different body types, shoulder widths, and neck lengths. This dynamic adjustability eliminates the need for users to search through multiple pillows.
Solution Approach 2:
The device allows users to change key parameters such as inclination angle (10°-60°), support height, and orientation to match their specific physical characteristics. These parameter adjustments provide a customized fit while maintaining manufacturing simplicity.

AI summary
A method for alleviating the dizziness symptoms of a person suffering from benign paroxysmal positional vertigo comprising the steps of: positioning the head of the person on a head-rest device that is formed of a first pillow structure; a second pillow structure with at least one slanted surface; and a non-permanent fastener on at least one surface of the first pillow structure and one surface of the second pillow structure so that the first and the second pillow can be placed in a user-selected configuration one on top of the other and the relative positions of the first pillow structure to the second pillow structure is fixed by the non-permanent fastener. The second pillow structure overhangs the first pillow structure so as to define an overhang region. The method includes the step of adjusting the second pillow structure so as to position a sleeping surface of the second pillow structure at an angle between about 20 degrees and 60 degrees relative to a horizontal reference surface. The overhang region is configured to receive a head and neck region of the person.
