Extended-range versatilely-configurable user-assembled adjustable, and high-low adjustable, beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable beds are cumbersome and costly to ship and assemble, often requiring heavy machinery for delivery and assembly, and are not suitable for larger individuals due to instability and mechanical failure, especially when designed for home use.
Innovation Solution
A modular, user-assembled adjustable bed system with boltable stanchions and a lift mechanism that allows for adjustable height and contour adjustments, enabling easy assembly and configuration without tools, and can be shipped in standard-sized boxes for minimal cost and handled by one person, using interchangeable parts to achieve high-low and Trendelenburg positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adjustable beds are designed with heavy-duty mechanisms to support larger individuals, then the bed can support higher weights, but the bed becomes more cumbersome and costly to ship and assemble
Solution Approach 1:
The bed is divided into modular sections that can be easily assembled and disassembled. The frame consists of multiple sections connected by simple joining mechanisms, allowing the bed to be shipped in compact pieces and assembled by consumers without specialized tools or machinery.
Solution Approach 2:
The head and foot sections are extracted as separate modular units that can be independently assembled. This allows the bed to be shipped in smaller, more manageable packages and assembled in a straightforward sequence, reducing overall assembly complexity while maintaining structural integrity for supporting larger individuals.
2Ease of operation
If traditional adjustable beds use complex mechanisms for height and contour adjustment, then the bed achieves precise positioning, but the bed requires heavy machinery for delivery and assembly
Solution Approach 1:
The bed incorporates dynamic adjustment mechanisms that allow the frame sections to be easily reconfigured between different height and contour positions. The modular design enables simple attachment and detachment of components, providing adjustability without requiring complex assembly machinery or incurring high shipping costs.
3Volume of stationary object
If the bed is designed to be compact for shipping, then the shipping cost is minimized, but the bed may not provide sufficient support for larger individuals
Solution Approach 1:
The bed sections are designed to nest within each other during shipping, with smaller components fitting into larger ones. This minimizes the shipping volume and associated costs while maintaining the structural integrity of each component to support larger individuals when assembled.
Solution Approach 2:
The bed frame utilizes composite construction with high-strength materials that provide sufficient structural support for larger individuals while occupying minimal space during shipping. The materials are engineered to maximize strength-to-volume ratio, ensuring both compact shipping and adequate load-bearing capacity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design allows for versatile and strong adjustable beds that can be easily assembled and configured by users, reducing shipping and assembly costs, and supports individuals up to 400 lbs with stability and safety, while being compact and affordable.
Implementation Method 1
The kit can be assembled into a bed having an upper surface that is variably dynamically adjustable in height above two different base elevations above a floor
Implementation Method 2
one or more motors to move the swing arms about their hinged connection to the stanchions to variously elevate the upper surface of the bed above the floor

AI summary
A high-low bed having a substantially rectangular upper surface is variably dynamically adjustable in elevation above a floor by action of a substantially planar substantially rectilinear upper frame presenting an upper surface to the bed, four stanchions of selectable length boltable at each of four opposing points under the upper frame, four swing arms hinge-connected at their first ends to the bottom of each of the four stanchions and at their second ends to wheels resting upon the floor. One or more motors move the swing arms about their hinged connection to the stanchions to variously elevate the upper surface of the bed above the floor. Nonetheless to its large height adjustment range, the entire bed breaks down to be shipped in two standard freight shipping boxes.
