Adjustable Bed Base with Multi-Motor Tilt for Sleep Apnea Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds are limited in their ability to adjust positions, particularly for patients with sleep apnea, as they only allow two adjustable positions without provision for headrest or footrest adjustments, making them unsuitable for comfortable sleep and relaxation.
Innovation Solution
An adjustable bed base with a bed frame, deck, and motorized components that allow for multiple comfortable positions, including backrest tilting, footrest tilting, and bed lifting, controlled by a remote control with levers and motors, enabling automatic adjustment to desired angles and heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable beds use a fixed foot support mounted to the adjusting mechanism, then the structure is simple, but the bed can only adjust to two positions and cannot accommodate headrest or footrest adjustments
Solution Approach 1:
The bed is divided into separate functional segments: headrest assembly, middle section, and footrest assembly. Each segment can be independently adjusted to different positions and angles, allowing the bed to accommodate multiple positions including zero gravity, sitting, and elevated configurations without requiring complete structural redesign
Solution Approach 2:
The bed structure transitions from a fixed configuration to a dynamic, multi-position system. The headrest and footrest assemblies incorporate movable joints and adjustment mechanisms that allow continuous position changes, enabling the bed to adapt to various user needs while maintaining structural integrity through engineered connection points
2Ease of operation
If manual adjustment mechanisms are used, then the device is simple to manufacture, but patients cannot easily change bed positions without caregiver assistance
Solution Approach 1:
The bed incorporates motorized adjustment mechanisms that allow patients to independently change bed positions using remote controls or handheld controllers. The system includes multiple motors positioned at strategic locations that can be activated by the patient without caregiver assistance, enabling self-adjustment to various positions including zero gravity and elevated configurations
Solution Approach 2:
Manual mechanical adjustment systems are replaced with electric motorized mechanisms. The motors are integrated into the bed frame structure and connected to the headrest, middle section, and footrest assemblies through linkages and joints, providing powered adjustment while maintaining a relatively compact and integrated design
3Adaptability or versatility
If the foot support is fixedly mounted to the adjusting mechanism, then the construction is simple, but the bed cannot tilt in multiple positions for backrest, footrest, and bed lifting
Solution Approach 1:
The frame is segmented into distinct adjustable sections with independent mounting points and connection mechanisms. The headrest assembly, middle section, and footrest assembly are connected through articulated joints that allow each section to tilt and adjust independently, enabling multiple positioning configurations including backrest tilting, footrest elevation, and bed lifting
Solution Approach 2:
The bed structure incorporates multi-dimensional adjustment capabilities beyond simple elevation. The articulated joints and connection mechanisms allow movement in multiple planes, enabling backrest tilting, footrest angle adjustment, and overall bed frame elevation simultaneously, creating a three-dimensional positioning system
