Adjustable Bed Foundation with Acoustic Snore Detection and Auto-Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed systems lack the ability to automatically detect snoring and adjust their position to mitigate it without disturbing the sleeper or their partner, as they rely on manual intervention or simplistic noise-based detection methods.
Innovation Solution
A bed system equipped with acoustic and pressure sensors that use machine learning to detect snoring and adjust the bed's foundation to a reverse Trendelenburg position, elevating the head relative to the feet, to reduce snoring through automated and quiet adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If automated snore detection and bed adjustment systems are implemented, then snoring can be reduced without waking the user, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing modalities (acoustic sensors for sound detection, pressure sensors for body position and movement detection) into a unified bed system. The controller integrates signals from both sensor types to improve snore detection accuracy and differentiate between snoring and other sounds or movements, thereby reducing false positives while managing system complexity through coordinated multi-sensor operation.
Solution Approach 2:
The bed system automatically detects snoring events and adjusts the foundation position without requiring user intervention. The controller autonomously processes sensor data, determines when snoring is occurring, and activates the articulation system to reposition the bed foundation, enabling the system to self-regulate and reduce snoring independently.
2Object-affected harmful factors
If the bed foundation is adjusted to reduce snoring, then snoring is mitigated, but the user's sleep position changes which may affect comfort
Solution Approach 1:
The bed foundation is designed with dynamic adjustability, allowing the head portion to be elevated relative to the foot portion at variable angles. This dynamic positioning capability enables the system to optimize the reverse Trendelenburg angle to reduce snoring while maintaining user comfort, and to return to neutral position when snoring stops, adapting to the user's needs throughout the sleep cycle.
Solution Approach 2:
The system continuously monitors snoring events and user movement through acoustic and pressure sensors. When snoring is detected, the foundation adjusts to a reverse Trendelenburg position; when snoring ceases or the user wakes, the system provides feedback by returning to neutral position. This closed-loop feedback mechanism balances snore reduction with user comfort and autonomy.
3Measurement precision
If acoustic sensors are used for snore detection, then detection capability is improved, but false detection from other sounds increases
Solution Approach 1:
The system merges acoustic sensor data with pressure sensor data to improve detection reliability. The controller cross-validates signals from both sensor types: acoustic sensors detect potential snoring sounds while pressure sensors monitor body movement and position. This multi-modal approach confirms genuine snoring events and filters out false positives from other sounds or movements, enhancing both detection accuracy and reliability.

AI summary
Disclosed herein are systems and methods for detecting snore and automatically adjusting a bed system to a position intended to mitigate the snore. The bed system can include a mattress, an adjustable foundation, and a controller having a processor. The processor can be configured to generate, in response to sensing snoring from a user of the bed system, instructions for tilting the adjustable foundation to a predetermined position such that an angle between a head portion of the adjustable foundation and the ground is greater than an angle between a foot portion of the adjustable foundation and the ground. The ground can be a horizontal plane. The predetermined position can be a position intended to mitigate snore.
