An adjustable bed device that gathers biological signals like heart rate and breathing rate, analyzes them, and adjusts temperature or cooling based on sleep phase and user preferences, also controlling other home appliances to optimize sleep environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electric blanket is used to heat the bed, then the bed temperature is improved, but the automation and additional functionality are lacking
Solution Approach 1:
The bed device integrates multiple functions including heating, cooling, biological signal monitoring (heart rate, breathing rate, temperature), and automated control based on sleep phase detection. This transforms a simple heating blanket into a multi-functional smart bed system that adapts to different sleep needs and phases.
Solution Approach 2:
The system automatically monitors biological signals, determines sleep phase, and adjusts temperature without manual intervention. The bed device self-regulates heating and cooling based on real-time physiological data, eliminating the need for users to manually adjust settings.
2Ease of operation
If manual control of electric blanket is used, then the operation is simple, but the adaptability to sleep phases is poor
Solution Approach 1:
The system automatically monitors biological signals, determines sleep phase, and adjusts temperature without manual intervention. The bed device self-regulates heating and cooling based on real-time physiological data, eliminating the need for users to manually adjust settings.
Solution Approach 2:
The system continuously monitors biological signals (heart rate, breathing rate, temperature) and uses this feedback to dynamically adjust bed temperature. The closed-loop control ensures the bed adapts to changing sleep phases and physiological states in real-time.
3Measurement precision
If automated bio signal monitoring is implemented, then the sleep phase detection is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple biological sensors (heart rate, breathing rate, temperature sensors) into an integrated bed device. By merging these sensing functions with processing and control systems, the patent achieves precise sleep phase detection while managing complexity through integration rather than separate components.
