Infant Sleep Monitoring With Multi-Sensor Breathing and Cry Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective methods to monitor infant breathing and emotional states in the home setting, which is crucial for preventing Sudden Infant Death Syndrome (SIDS) and understanding infant needs, as they rely on medical equipment unavailable at home.
Innovation Solution
A smart infant monitoring system utilizing a plurality of sensors, including sound and motion sensors, with AI and ML models to analyze infant cries, vital signs, environmental data, and sleep patterns to identify emotional states and potential health issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical monitoring equipment is used in hospital settings, then breathing detection reliability is improved, but device complexity and cost increase making it unavailable for home use
Solution Approach 1:
The patent replaces complex mechanical medical monitoring equipment with acoustic and optical sensors that detect breathing through sound waves and light absorption. This substitution maintains reliability while dramatically reducing device complexity and cost for home deployment
Solution Approach 2:
The patent uses optical sensors to detect breathing movements by capturing light reflection patterns from the infant's chest. This creates an optical copy of the breathing motion, enabling accurate detection without direct physical contact or complex mechanical components
2Measurement precision
If multiple sensors and AI analysis modules are added to interpret infant cries, then measurement precision of infant states is improved, but device complexity increases
Solution Approach 1:
The patent divides the cry analysis function into separate modules: sound sensors capture audio, AI algorithms analyze cry patterns, and different cry types are classified into distinct categories (hunger, discomfort, pain). This segmentation improves measurement precision while managing system complexity through modular design
Solution Approach 2:
The patent creates a universal monitoring system that uses the same sensor array and processing platform to detect multiple infant states including breathing apnea, cry analysis, sleep monitoring, and movement detection. This multi-functionality improves measurement precision across different parameters while avoiding the complexity of separate dedicated devices
