Electric Bed with Presence Detection for Conditional Alarm Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric beds with alarm functions do not consider whether a user is present before activating the alarm, leading to unnecessary trouble when the user is away, and the alarm settings are inflexible, especially during emergencies.
Innovation Solution
An electric bed with a monitoring module, including a thin film pressure sensor and a main control box, that detects user presence to determine whether to activate the wake-up function, allowing customizable wake-up modes and times via a wireless communication module connected to an intelligent terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the alarm clock bed operates according to set alarm time without detecting user presence, then the alarm function is simple to implement, but it causes unnecessary trouble when the user is away
Solution Approach 1:
The bed system automatically detects user presence through pressure sensors and autonomously determines whether to activate the alarm function, eliminating the need for users to manually check or adjust settings based on their presence status
Solution Approach 2:
The system continuously monitors pressure sensor data to detect user presence and provides feedback to the control unit, which then adjusts alarm activation accordingly, creating a closed-loop control system that adapts to real-time conditions
2Device complexity
If the alarm time is fixed and cannot be changed easily, then the alarm clock bed has simple control structure, but it cannot respond to emergency situations when users need to travel or go out
Solution Approach 1:
The alarm time and alarm mode are transformed from fixed parameters to dynamically adjustable parameters, allowing users to modify settings in real-time through wireless terminals or local controls to adapt to changing schedules and emergency situations
Solution Approach 2:
The system integrates multiple alarm modes (lighting, vibration, bed plank rotation) and multiple control interfaces (wireless terminal, local controls) to provide universal functionality that can handle various user needs and emergency scenarios
3Reliability
If the alarm clock bed activates wake-up function regardless of user presence, then the alarm function is reliable and simple, but it brings unnecessary troubles when users travel or go out for business trips
Solution Approach 1:
The control unit receives real-time feedback from pressure sensors about user presence and automatically adjusts alarm activation, ensuring the alarm only activates when a user is actually present on the bed, thereby eliminating unnecessary trouble during travel or business trips
Solution Approach 2:
The system autonomously monitors user presence and makes intelligent decisions about alarm activation without requiring user intervention, automatically preventing false alarms when no user is present while maintaining reliable alarm function when a user is present
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The electric bed ensures the alarm function is only activated when the user is present, reducing unnecessary activation and providing personalized wake-up experiences by integrating multiple wake-up modes and allowing flexible setting of wake-up times and modes from anywhere.

AI summary
An electric bed, comprising: a bed body, a plurality of bed planks, a wake-up device, a clock and a main control box (2). The main control box (2) is electrically connected to the wake-up device and the clock, and is applicable for storing a wake-up time. The electric bed further comprises a monitoring module (1). The monitoring module (1) comprises a processing module and a sensor, wherein the sensor is electrically connected to the processing module, and is applicable for monitoring whether a user has left the bed; if the sensor monitors that the user has not left the bed, the processing module activates the wake-up device when the wake-up time on the clock is due according to the stored wake-up time; and if the sensor monitors that the user has left the bed, the processing module does not activate the wake-up device when the wake-up time on the clock is due. The electric bed can automatically decide whether to perform the wake-up function, thereby improving the degree of intelligentization, and can further comprise a wireless communication module (3) for receiving the wake-up time and the wake-up mode set by an intelligent terminal, which increases the user's operation freedom.
