Voice-Controlled Adjustable Bed With Unified Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable beds lack the ability to control additional devices and provide independent functionality, limiting user convenience and independence, especially for individuals with medical needs who require specific positions for comfort and recovery.
Innovation Solution
The adjustable bed system incorporates an air inflatable mattress with flex regions, a programmable logic controller, remote memory storage, and various remote control options (cell phone, Bluetooth, ultra-wide band, wireless USB) to control bed positions, vibration, and external devices like audio equipment and air purification systems, enhancing user independence and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If basic adjustable bed functions are provided, then bed section positioning is achieved, but user independence and control of additional devices is limited
Solution Approach 1:
The adjustable bed system is enhanced with multi-functionality by integrating control capabilities for multiple devices beyond basic bed positioning. The system can control audio equipment, air purification systems, lighting, and other environmental devices through a unified remote control interface, allowing one device to perform multiple functions and thereby improving adaptability without proportionally increasing complexity
Solution Approach 2:
A programmable logic controller serves as an intermediary device that receives commands from remote controls and translates them into appropriate actions for both bed actuators and external devices. This mediator architecture allows the system to manage increased functionality while maintaining relatively simple control interfaces and reducing the complexity burden by centralizing control logic
2Reliability
If users require specific positions for medical needs, then comfort and recovery are improved, but user independence is reduced
Solution Approach 1:
The system incorporates memory storage functionality that remembers previously configured medical positions. Users can program and store optimal positioning configurations for medical needs, and the system automatically recalls these positions with a single command, eliminating the need for manual re-adjustment and thereby improving ease of operation while maintaining reliable medical positioning accuracy
Solution Approach 2:
The system provides feedback mechanisms that confirm when medical positions have been accurately achieved and maintained. Through remote control interfaces and visual indicators, users receive confirmation that their bed has reached the prescribed medical position, enhancing both reliability of positioning and user independence through clear system-response communication
3Ease of operation
If multiple control devices are integrated, then user convenience is improved, but system complexity increases
Solution Approach 1:
The control system is segmented into modular components, with different remote control options (cell phone, Bluetooth, ultra-wide band, wireless USB) that can function independently or in combination. Each communication protocol represents a separate module that can be activated based on user preference, allowing the system to provide multiple control methods without requiring all components to operate simultaneously, thereby improving user convenience while managing complexity through modular architecture

AI summary
A controller for an adjustable bed can accept voice input, such as spoken commands to control functions of an adjustable bed. The controller can also accept voice commands to control functions of a second system associated with the bed. One or more voice commands can result in both the adjustable bed and the second system functionality being controlled.
