Modular user-assembled adjustable, and high-low adjustable beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds are heavy and costly to ship due to their assembled form, requiring high freight costs and two-man delivery teams, and existing modular designs are either flimsy or unstable, posing safety concerns, especially for larger users.
Innovation Solution
A modular adjustable bed system comprising two or more frame sections that can be assembled by a single adult without tools, using a semi-permanent engagement mechanism with sliding protrusions and locking mechanisms, allowing for adjustable motorization to achieve Trendelenburg, anti-Trendelenburg, or high-low positions, and optimized for shipping on standard pallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adjustable beds are shipped in assembled form, then structural stability is ensured, but shipping costs increase and require two-man delivery teams
Solution Approach 1:
The bed frame is divided into multiple modular sections that can be shipped separately and assembled by the end user. This segmentation reduces shipping volume and cost while allowing the final assembled structure to achieve the required structural stability for use.
2Ease of operation
If modular bed sections are designed for easy assembly, then assembly simplicity improves, but structural strength may be compromised
Solution Approach 1:
The modular sections incorporate self-aligning features and user-friendly connection mechanisms that enable easy assembly without specialized tools or expertise, while maintaining structural integrity through engineered joint designs that provide adequate strength for the intended application.
3Ease of operation
If modular bed sections are designed for tool-free assembly, then assembly ease improves, but connection reliability may be reduced
Solution Approach 1:
The connection system uses intermediate components such as cam-locked mechanisms or bayonet-style connectors that can be engaged by hand to provide reliable, tool-free assembly. These intermediary mechanisms create secure mechanical interlocks that maintain connection reliability without requiring tools.

AI summary
A frame for an adjustable has a head section with two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails. The frame has a foot section having two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails, and an inner tube with a nose for each of the two sleeves and for moving between a first position retracted in the cavity of the sleeve and a second position extending from the cavity of the sleeve.
