Method of a touch screen remote control with feedback for an adjustable bed
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 basic adjustable bed functions are provided, then bed section positioning is achieved, but user independence and device control capability are limited
Solution Approach 1:
The adjustable bed control system is designed to perform multiple functions beyond basic bed positioning. The controller can control the bed sections, massage mechanisms, and integrate with external devices such as televisions, audio systems, and environmental controls. This multi-functionality allows a single system to handle diverse user needs without requiring separate control devices for each function.
Solution Approach 2:
A remote control device serves as an intermediary between the user and the complex bed system. The remote allows users to control bed functions and external devices without directly interacting with the complex control panel or wiring. Additionally, the system can interface with external controllers (such as television remotes) through intermediary communication protocols, enabling seamless control of multiple devices.
2Measurement precision
If multiple actuators are used for each adjustable section, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The bed is divided into multiple independently controllable sections (head section, foot section, knee section), each with its own actuator. This segmentation allows precise control of each body region without requiring multiple actuators within a single section. The controller can adjust each section to optimal positions for comfort and medical requirements.
Solution Approach 2:
The system controls actuator position through parameter changes rather than mechanical complexity. The controller adjusts motor parameters (speed, position, force) to achieve precise positioning. Memory functions store and recall specific parameter sets for different positions, enabling precise reproduction of optimal positions without additional mechanical components.
3Ease of operation
If users spend significant time in adjustable beds for medical reasons, then health benefits are achieved, but user independence and ability to control other devices is reduced
Solution Approach 1:
The adjustable bed system enables users to independently control their own positioning and entertainment without assistance. The bed can automatically adjust to pre-programmed positions, and users can operate the system themselves via remote control. This self-service capability is crucial for users who spend extended periods in bed and need to maintain independence.
Solution Approach 2:
The system incorporates feedback mechanisms that allow users to see and adjust settings in real-time. The control system responds to user inputs with immediate adjustments, and memory functions provide feedback by recalling preferred settings. This interactive feedback loop makes the complex system easy to operate and understand.
