Foldable Bed Frame With Scissor Reinforcement for Longitudinal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable beds suffer from longitudinal instability due to the lack of a reinforcing mechanism in their end legs, leading to either instability or complex structures, making them difficult to fold and expand easily.
Innovation Solution
A foldable bed design featuring pivotally connected side beams, tilt legs, end bars, and reinforcing bars that scissor and slide, along with telescoping legs and a middle bar mechanism, providing stability without compromising ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If end legs are reinforced with tilt bars, then longitudinal stability is improved, but device complexity increases
Solution Approach 1:
The end bar is divided into multiple segments (first end bar and second end bar) that can scissor relative to each other, allowing the structure to achieve stability through segmented movement rather than rigid reinforcement
Solution Approach 2:
The patent introduces dynamic scissor mechanisms where end bars and middle bars can pivot and scissor during folding and expanding operations, providing longitudinal stability through controlled dynamic movement rather than static rigid structures
2Stability of the object's composition
If complex reinforcing mechanisms are added, then longitudinal stability is improved, but ease of operation deteriorates
Solution Approach 1:
The reinforcing function is merged with the folding mechanism itself - the scissor motion of end bars and middle bars simultaneously provides longitudinal stability and enables folding/expanding operations, eliminating the need for separate reinforcing structures that would hinder operation
Solution Approach 2:
The scissor mechanisms automatically provide longitudinal stability during folding and expanding operations without requiring additional control mechanisms or complex operations from the user, making the stability feature self-activating during normal use

AI summary
A stronger foldable bed having a frame and a foldably soft cover attached thereto. The frame has two pairs of side bars each pivotally connected to a central link, a tilt leg pivotally connected to a free end of each side bar, three pairs of scissoring end or middle bars linking the two pairs of side bars, a pair of middle leg each containing a telescoping leg, a reinforcing bar each pivotally connected to one side bar and a sleeve covering on each tilt leg, and a journey limit formed on each tilt leg. The foldable bed is longitudinal stable, simple and strong, without sacrificing the easiness of operation of folding and expanding.
