Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Sleeping positions can exacerbate existing health issues such as sleep apneas by narrowing the airway, and existing technologies lack effective methods for real-time detection and correction of improper sleep positions.

Innovation Solution

Ear-worn devices, like earbuds, equipped with accelerometers and processors, detect sleep positions and generate therapy recommendations to adjust sleeping positions or modify respiratory therapy systems based on detected positions and pathologies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If sleeping on the back, then comfort is maintained, but airway narrowing occurs causing breathing restrictions

Engineering Contradiction:

Improveairway narrowingVSAvoidsleep position comfort

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system continuously monitors sleep position using accelerometers and provides real-time feedback through auditory cues to alert users when they are sleeping on their back, enabling them to change position to alleviate airway narrowing while maintaining comfort

AI summary

A processor of an ear-worn device such as an earbud may receive acceleration data from an accelerometer of the earbud. The processor may determine a position of a body wearing the earbud based on the acceleration data. The processor may determine a pathology of the body. The processor may generate, based on the position of the body and the pathology, a therapy recommendation. The processor may output an indication of the therapy recommendation via the earbud or one or more other devices.
