Mattress-Embedded Sensor System for Non-Intrusive Sleep Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleep quality measurement techniques are intrusive or inaccurate due to their distance from the sleeper, failing to consider environmental and lifestyle factors that significantly impact sleep.
Innovation Solution
Integration of sensors within a mattress assembly that measures various sleep parameters, combined with a mobile device for data processing and user input, to provide accurate sleep diagnostics and recommendations based on environmental and lifestyle data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are mounted on the individual's body (headband or wristband), then measurement precision is improved, but ease of operation deteriorates due to intrusiveness
Solution Approach 1:
The patent uses the mattress as an intermediary device that indirectly measures sleep parameters through sensors embedded in the mattress structure. This mediator approach allows accurate measurement of sleep characteristics (breathing, heart rate, movement) without direct contact with the user's body, thus maintaining measurement precision while eliminating the intrusiveness of body-mounted sensors.
2Ease of operation
If remotely mounted sensors (cameras and microphones) are used, then ease of operation is improved, but measurement precision deteriorates due to distance from the individual
Solution Approach 1:
The patent merges multiple sensor types (pressure sensors, accelerometers, temperature sensors, humidity sensors, light sensors) into a single integrated mattress system. This combination of sensors in close proximity to the user provides comprehensive sleep parameter measurement with high precision, overcoming the limitations of distant remote sensors while maintaining ease of operation through unified non-intrusive monitoring.
3Measurement precision
If comprehensive sleep analysis including environmental and lifestyle factors is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The mattress system is designed with multi-functionality to measure diverse sleep parameters (pressure distribution, movement, temperature, humidity, light exposure) and integrate them with environmental and lifestyle data. This universal approach consolidates multiple measurement functions into a single system, improving comprehensive sleep quality assessment while managing complexity through integrated design rather than separate devices.
Data Source
AI summary
Systems and methods described herein relate to a sleep diagnostic system including a mattress assembly, a plurality of sensors, data acquisition circuitry, an input device, a sleep processor, and a display device. The mattress assembly may have a sleeping surface, and the plurality of sensors may be disposed within the mattress assembly below the sleeping surface. The sensors are configured to measure at least one sleep condition and output data signals indicative of the sleep condition. The sleep processor receives signals from both the sensors and one or more other input devices, and determines a sleep characteristic based upon these received signals. The display device, which includes circuitry and a graphical user interface, receives the sleep characteristic from the sleep processor and displays it to the user.
