Methods and systems for gathering and analyzing human biological signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleep support technologies, such as electric blankets, require manual operation and lack advanced functionality to optimize sleep environments, failing to provide tailored comfort and wake-up times that align with the user's sleep phases.
Innovation Solution
A system that gathers human biological signals like heart rate, breathing rate, and temperature, and environment properties to control home appliances, such as bed heating devices, thermostats, and lights, to create a conducive sleep environment and wake users during light sleep phases to minimize disorientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of electric blankets is used, then users can control bed warming, but users must remember to manually turn on and off the blanket
Solution Approach 1:
The system automatically monitors sleep stages through sensors and controls the heating blanket without user intervention. The processor detects when the user enters sleep mode and automatically activates the heating blanket, and turns it off when the user wakes up, eliminating the need for manual operation.
Solution Approach 2:
The system uses sensors to continuously monitor physiological parameters (heart rate, breathing rate, body position) and provides feedback to the processor, which automatically adjusts the heating blanket operation based on the detected sleep stage, creating a closed-loop control system.
2Adaptability or versatility
If electric blankets provide only heating function, then the device structure remains simple, but no additional functionality is provided
Solution Approach 1:
The heating blanket is transformed into a multi-functional device that not only provides heating but also monitors sleep stages through integrated sensors (heart rate, breathing rate, body position) and automatically adjusts heating based on detected sleep phases, combining multiple functions in one device.
Solution Approach 2:
The system merges the heating function with sleep monitoring and control functions by integrating sensors, processors, and control circuits into the blanket structure, creating a unified system that performs multiple operations simultaneously.
3Ease of operation
If wake-up time is fixed regardless of sleep phase, then alarm scheduling is simple, but users feel tired and disoriented when woken
Solution Approach 1:
The wake-up alarm time is made dynamic rather than fixed. The system continuously monitors sleep stages and automatically adjusts the alarm time to coincide with light sleep phases, optimizing user wake-up experience based on real-time physiological data while maintaining simple user interface for setting preferred wake-up windows.
