Adjustable Bed Assembly with Nested Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable beds are not efficiently designed for storage and shipping due to their bulkiness, which complicates transportation and storage processes.
Innovation Solution
An adjustable bed system with a mattress and an adjustment mechanism that allows for a flat configuration for use and an inclined configuration for comfort, featuring a compressible design for storage and shipping, utilizing a hook and loop fastener system and a coupler to prevent forward movement, and a removable vacuum bag for further compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjustable bed system is designed with a rigid structure to maintain stability and functionality during use, then the bed can provide reliable support and comfort, but the bed occupies large spatial volume for storage and shipping
Solution Approach 1:
The bed mattress is divided into multiple independent sections (head section, foot section, intermediate section) that can move relative to each other. The adjustment mechanism is segmented into a base, support structure, and actuator components that can be compacted separately. This segmentation allows the bed to maintain structural integrity during use while enabling compression for storage.
Solution Approach 2:
The bed transitions from a static rigid structure during use to a dynamic compressible structure for storage. The adjustment mechanism includes movable support panels, flexible couplers, and retractable actuators that allow the bed to change its spatial configuration. The head section can be dynamically adjusted between elevated and flat positions while maintaining support reliability.
2Volume of moving object
If the adjustment mechanism is made compact for storage, then the bed can be compressed to reduce volume, but the mechanism complexity increases to enable both compression and functional configurations
Solution Approach 1:
The adjustment mechanism components are nested within each other to maximize compactness. The support panels are positioned within the mattress thickness, the coupler is nested within the adjustment mechanism housing, and the actuator retracts into its housing. This nested arrangement reduces the overall volume while maintaining all necessary functional components.
Solution Approach 2:
The adjustment mechanism serves multiple functions: it provides structural support during use, enables elevation adjustment, and facilitates compression for storage. The coupler both connects the support panel to the base and allows controlled movement during compression. The actuator both elevates the head section and can be retracted to enable compact storage configuration.
3Productivity
If the bed is compressed for storage and shipping, then transportation and storage efficiency improves, but the compression force may affect the structural integrity and comfort properties of the mattress
Solution Approach 1:
The mattress cover and internal structures incorporate flexible materials that can withstand compression forces. The coupler includes flexible panels that bend during compression while maintaining connection integrity. The support panels are designed with flexible edges that can deform under compression but return to their original position, preserving mattress structural integrity and comfort properties.

AI summary
An adjustable bed system includes a mattress and an adjustment mechanism. The mattress includes a head portion and a foot portion rearward of the head portion. The head portion defines a cavity that is downwardly open. The adjustment mechanism includes a lower base, an upper support that is movably coupled to the lower base, and an actuator operable to move the upper support relative to the lower base. The adjustment mechanism is positioned in the cavity and is coupled to the mattress. When the actuator is operated, the adjustment mechanism moves the adjustable bed system between a flat configuration in which the head portion is substantially coplanar with the foot portion and an inclined configuration in which the head portion is inclined relative to the foot portion.
