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 sections that can be assembled by a single adult without tools, using a semi-permanent engagement mechanism with sliding protrusions and tubular cavities, and optional additional motors for position adjustment, allowing for Trendelenburg, anti-Trendelenburg, and high-low positions, while being lightweight and securely connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adjustable beds are shipped in assembled form, then structural stability is maintained, but freight costs and delivery complexity increase significantly
Solution Approach 1:
The adjustable bed is divided into multiple modular frame sections that can be separated for shipping and reassembled by the user. This segmentation reduces shipping volume and cost while maintaining structural integrity when assembled, directly resolving the contradiction between stability and freight cost.
2Ease of operation
If modular adjustable bed sections are connected with simple assembly mechanisms, then assembly ease is improved, but connection strength and stability decrease
Solution Approach 1:
The connection mechanism uses nested tubular cavities and protrusions where one section fits into another, creating a strong interlocking joint that is simple to assemble. The nested design provides both ease of assembly and strong mechanical connection, resolving the contradiction between assembly ease and connection strength.
3Strength
If modular adjustable bed sections are connected with complex assembly mechanisms, then connection strength is improved, but assembly complexity increases
Solution Approach 1:
The assembly mechanism is designed to be self-aligning and self-securing, where the tubular protrusions automatically guide and lock into the cavities without requiring complex tools or procedures. This self-service design maintains strong connections while minimizing assembly complexity.
4Stability of the object's composition
If adjustable beds are designed as single integrated units, then structural rigidity is maintained, but shipping and assembly cost increase
Solution Approach 1:
The bed frame is segmented into multiple sections that can be shipped separately and assembled by the user, improving shipping efficiency and reducing costs while maintaining structural rigidity when assembled, directly addressing the contradiction between rigidity and shipping productivity.
5Loss of time
If modular connection mechanisms are designed for easy user assembly, then assembly time is reduced, but connection reliability may decrease
Solution Approach 1:
The nested tubular connection mechanism provides intuitive alignment and automatic locking, enabling quick user assembly while ensuring reliable and stable connections. The design achieves both rapid assembly and high connection reliability through its self-aligning geometry.

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.
