Adjustable Bed Touchscreen Presets for Multi-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 development of an adjustable bed system that includes an air inflatable mattress with flex regions, a programmable logic controller, remote memory storage, and various remote control options such as cell phone, Bluetooth, and ultra-wide band controls, allowing users to control bed positions and additional devices like audio equipment, lamps, and air purification systems from the bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable bed includes only basic bed section positioning functions, then the device complexity is low, but the user independence and ability to control additional devices is limited
Solution Approach 1:
The adjustable bed control system is designed to perform multiple functions beyond basic bed positioning. The control device can control the adjustable bed sections, audio equipment, lamps, air purification facilities, and other connected devices through a single unified interface, allowing one device to serve multiple purposes and reducing the need for separate control systems for each function
Solution Approach 2:
A control box serves as an intermediary device that receives signals from the control device and distributes them to various target devices including bed actuators, audio equipment, lighting, and air purification systems. This mediator architecture allows the control device to manage multiple functions without directly connecting to each individual device, simplifying the overall system structure
2Ease of operation
If a user with limited mobility must leave the bed to control devices, then the device complexity is low, but the ease of operation deteriorates
Solution Approach 1:
The system enables users to control all connected devices and adjust bed positions entirely from the bed position without needing to leave or manually operate separate devices. The control device allows users to service themselves by providing comprehensive control capabilities within reach of the user in bed, eliminating the need to起身 for routine control tasks
Solution Approach 2:
Multiple control functions for bed positioning, audio equipment, lighting, and air purification are merged into a single control device interface. This consolidation allows users to access all functions from one location (the bed), improving ease of operation by eliminating the need to interact with multiple separate control devices or leave the bed
3Manufacturing precision
If the adjustable bed includes multiple actuators for each section, then the manufacturing precision and position control are improved, but the device complexity increases
Solution Approach 1:
The adjustable bed is divided into multiple independently controllable sections, each with its own actuator(s). This segmentation allows precise control of each section's position while maintaining overall system manageability through modular architecture, where each segment can be controlled independently but coordinated through the unified control system
4Adaptability or versatility
If the adjustable bed provides basic positioning functions only, then the ease of manufacture is high, but the user independence and comfort are limited
Solution Approach 1:
The system includes pre-programmed settings that store commonly used bed positions and device configurations. These preset configurations are prepared in advance and can be quickly recalled, providing users with customized settings without requiring complex manual configuration each time, thus balancing versatility with ease of manufacture
Data Source
AI summary
A control command is received via a touch screen from a user. The control command is directed to recalling a user-selected bed position of an adjustable bed. Recalling includes: identifying a row in a data table representing a user-selected bed position and retrieving an increment value from the row. The increment value specifies one of a range of available positions for the adjustable bed. A component of the adjustable bed is controlled to meet the increment value The component includes at least one of an actuator and a vibration motor.
