Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sleep monitoring methods are used, then device complexity is reduced, but measurement precision and reliability of sleep apnea detection deteriorate
Solution Approach 1:
The patent combines multiple sensing functions (audio detection, position detection, and bed control) into an integrated intelligent bed monitoring system. The audio sensors detect breathing sounds and snoring, the processor analyzes this data to determine sleep apnea conditions, and the controlling module automatically adjusts bed board positions to treat the condition, merging detection and treatment functions in one system.
Solution Approach 2:
The intelligent bed monitoring device performs multiple functions: it monitors sleep quality through audio sensors, detects sleep apnea conditions, calculates audio source directions to locate the user, and controls bed board adjustments to various modes (elevated, flat, reversed) to treat sleep apnea. This multi-functional approach improves measurement precision without requiring separate specialized devices.
2Reliability
If bed position is adjusted frequently to treat sleep apnea, then sleep quality improves, but user disturbance increases
Solution Approach 1:
The system automatically detects sleep apnea conditions through audio sensors and self-adjusts the bed position without requiring user intervention. The processor continuously monitors breathing sounds, identifies apnea events, and the controlling module automatically adjusts bed board positions to treat the condition, allowing the system to serve itself and the user without external input.
Solution Approach 2:
The system implements continuous feedback by monitoring audio signals from breathing sounds, analyzing them to detect sleep apnea conditions, and automatically adjusting bed position in response. This closed-loop feedback mechanism ensures the bed position is optimized for treating sleep apnea while minimizing user disturbance through automated, responsive adjustments.
