Fold-Away Bunk Bed Articulation for Compact Independent Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fold-away bunk beds occupy significant space when folded and lack a structurally compact and reliable articulation system for independent operation of bedsprings, compromising both functionality and aesthetics.
Innovation Solution
A fold-away bunk bed design featuring a supporting framework with independently hinged bedsprings using an articulated structure within lateral shoulders, actuated by gas cylinder mechanisms and locking pins, allowing each bedspring to move between horizontal and vertical positions, and incorporating an adjustable ladder and padded barriers for enhanced stability and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bedsprings are hinged to the framework using a shared articulation system, then the structure is simpler, but the bedsprings cannot be operated independently and the folded position occupies more space
Solution Approach 1:
The patent divides the articulation system into separate independent hinges for each bedspring. Each bedspring has its own articulated structure hinged to the framework at specific shoulders, allowing independent rotation and positioning. This segmentation enables each bedspring to be operated independently while maintaining a compact folded position within the framework.
2Volume of stationary object
If the framework thickness is increased to contain the folded bedsprings, then the bedsprings can be fully enclosed, but the space occupation increases and the structure becomes less compact
Solution Approach 1:
The patent utilizes the vertical dimension by hinging the bedsprings at shoulders of the framework, allowing them to rotate between horizontal (open) and vertical (folded) positions. This dimensional transition enables the bedsprings to be contained within the framework's vertical space rather than requiring increased horizontal thickness, maintaining compactness while achieving full enclosure.
3Shape
If the bedsprings are fully enclosed within the framework in folded position, then the aesthetic appearance is improved, but the articulation system becomes more complex and less reliable
Solution Approach 1:
The patent designs the articulated structure so that when the bedsprings are in the folded vertical position, they nest within the framework's lateral shoulders. The independent hinges and articulation mechanisms are contained within the framework structure itself, achieving a clean enclosed appearance while maintaining mechanical reliability through proven hinge technology.

AI summary
A fold-away bunk bed including a supporting framework to which two bedsprings, an upper bedspring and a lower bedspring, are hinged; the bedsprings have at least two working positions: an open position, in which the bedsprings are in a horizontal position, and a closed position, in which they are in a vertical position and are substantially included within the framework; the bed is characterized in that each one of the bedsprings is hinged to the framework by an independent articulated structure that is contained in a lateral shoulder of the framework.
