Adjustable Bed Remote Memory Control for Independent Device Operation
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 air purification and power outlets, enhancing user independence and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable bed provides basic position adjustment functions, then it meets medical positioning requirements, but it lacks the ability to control additional devices and provide user independence
Solution Approach 1:
The adjustable bed controller is designed to perform multiple functions: controlling bed position adjustment, managing air mattress inflation/deflation, and operating external devices such as lights, TVs, and audio equipment. This multi-functional approach allows a single device to replace what would otherwise require separate control systems, thereby increasing adaptability without proportionally increasing complexity.
Solution Approach 2:
The patent introduces remote control devices (wireless remote, cell phone interface) as intermediaries between the user and the bed system. These intermediaries enable users to control bed functions and external devices from a distance, enhancing user independence and accessibility without requiring direct interaction with the main controller, thus improving versatility while maintaining manageable system complexity.
2Ease of operation
If the bed includes multiple control features and external device integration, then user independence improves, but the system becomes more complex
Solution Approach 1:
The adjustable bed system incorporates self-service features including automatic position memory recall, where the controller automatically restores predetermined bed positions when users return from absences. The system also includes automatic air mattress pressure regulation and device control without requiring user intervention, thereby enhancing ease of operation while the automated nature of these features prevents complexity from escalating.
Solution Approach 2:
The patent implements memory functions that store and recall predetermined bed positions and control settings. By copying and reproducing previously successful configurations, the system eliminates the need for users to manually re-adjust settings, significantly improving ease of operation. The memory controller replicates complex multi-device states with simple recall commands, effectively managing system complexity.
3Manufacturing precision
If the bed uses an air inflatable mattress with flex regions, then comfort and positioning precision improve, but manufacturing and assembly become more difficult
Solution Approach 1:
The air mattress is divided into multiple independently controllable chambers or regions, each capable of being inflated or deflated to specific pressure levels. This segmentation allows precise positioning and contouring to user needs, achieving high manufacturing precision. The modular chamber design also simplifies assembly compared to a single complex bladder, as each chamber can be manufactured and tested separately before final assembly.
Solution Approach 2:
The patent employs pneumatic control through an air pump and valve system to regulate mattress firmness and positioning. By using air pressure rather than mechanical springs or rigid structures, the system achieves precise positioning control and comfort adjustment. The pneumatic system is relatively simple to manufacture and assemble compared to mechanical alternatives, as it requires only basic sealing, valves, and an air pump.
