Bunk bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bunk beds with detachable support bars or pipes require increased assembly effort and occupy more space, making them inconvenient for transportation and use as separate single beds.
Innovation Solution
A bunk bed frame design featuring top and bottom bedsteads connected by cross beams, with insert elements and support legs that allow for detachable and coinciding connecting points, reducing assembly workload and enabling easier transportation by allowing individual packing and connection of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support bar or pipe is divided into two sections with detachable connecting structures, then the bunk bed can be divided into two single beds for independent use, but the assembly effort increases and the strength of the support bar or pipe is affected
Solution Approach 1:
The connecting pipe is inserted into the support leg, forming a nested structure where one component fits inside another. This eliminates the need for separate connecting structures and reduces assembly complexity while maintaining the ability to detach and divide the bunk bed into single beds.
Solution Approach 2:
The connecting function and support function are merged into a single integrated structure where the connecting pipe serves both as a connector and as part of the support leg. This reduces the number of parts and simplifies assembly while preserving versatility.
2Adaptability or versatility
If the support bar or pipe is divided into two sections with detachable connecting structures, then the bunk bed can be divided into two single beds for independent use, but the strength of the support bar or pipe is affected
Solution Approach 1:
The nested insertion of the connecting pipe into the support leg creates a continuous load path that maintains structural strength. The overlapping nested structure distributes forces more effectively than separate connecting sections, preserving the strength of the support element even when divided.
3Device complexity
If the side bedstead is an integrate piece, then the structure is simple, but the occupied space is large and transportation is inconvenient
Solution Approach 1:
The bedstead is segmented into separable components (side bedsteads, connecting pipes, support legs) that can be detached and packed individually. This reduces the occupied volume during transportation while maintaining structural simplicity through standardized connection interfaces.
Solution Approach 2:
Components are designed to nest within each other when detached, with connecting pipes inserting into support legs and sides. This nested configuration minimizes the volume required for storage and transportation while keeping the overall structure simple and easy to reassemble.

AI summary
The present invention is provided with a bunk bed frame, comprising two top bedsteads, two bottom bedsteads and connecting pipes. The two top bedsteads are connected by top cross beams, two bottom bedsteads are connected by bottom cross beams, wherein two sides of the top bedstead are respectively disposed with an insert element, which extends downwardly. Two sides of the bottom bedstead are respectively disposed with a support leg. The lower portion of the connecting pipe is detachably connected to the support leg, a first connecting point of the connecting pipe and the support leg of the lower bedstead and a second connecting point of the support leg and the cross beam of the bottom bedstead coincide. The insert element is inserted into the connecting pipe, and detachably connected to the connecting pipe. A third connecting point of the insert element and the connecting pipe and a fourth connecting point of the insert element and the cross beam of the top bedstead coincide. The detachable connecting point of the top and bottom bedstead coincides with the connecting point of the top and bottom bedstead and the cross beam, so that the assembly can be finished without additional workload and screws, the assembling time can be reduced.
