Foldable Bed Frame Structure for Compact Transport and Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wooden bed frames occupy large spaces during transportation and are inconvenient to remove due to their size and the need for disassembly, requiring assistance and limiting access through corridors and elevators.
Innovation Solution
A foldable bed frame structure comprising two longitudinal supports, three transverse supports, and legs, where the longitudinal supports are connected through pivot members and U-shaped fixing plates, allowing for easy assembly and disassembly to reduce the frame's size for storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bed frame is made as an integral structure, then the structural strength is improved, but the space occupied for transportation increases and removal becomes inconvenient
Solution Approach 1:
The bed frame is divided into multiple independent components including longitudinal supports, transverse supports, and legs that can be separated for transportation and reassembled at the destination. This segmentation allows the bed frame to be disassembled into smaller parts that occupy less space during transportation while maintaining structural integrity when assembled.
Solution Approach 2:
The bed frame incorporates pivot connections that allow the structure to transition between a stable assembled state for use and a collapsed disassembled state for transportation. The dynamic capability of the pivot joints enables the frame to adapt its configuration, reducing its volume when needed while preserving structural strength during assembly.
2Ease of operation
If the bed frame is made as a separate frame and bed board, then the ease of removal is improved, but the complexity of assembly increases as parts must be disassembled or assembled one by one
Solution Approach 1:
The longitudinal supports and transverse supports are merged into an integrated folding mechanism where multiple components are connected through pivot joints that allow simultaneous movement. This merging reduces the number of separate assembly steps compared to traditional separate frame and bed board designs, as the supports can be assembled and folded together in a more streamlined process.
Solution Approach 2:
The pivot connections create dynamic joints that enable smooth transitions between assembled and disassembled states. These dynamic joints allow the frame components to move relative to each other in a controlled manner, simplifying the assembly process compared to rigid fixed connections that would require precise alignment and multiple fastening steps.
3Area of stationary object
If the bed frame is made large to provide sufficient sleeping space, then the comfort is improved, but the ability to pass through corridors and elevators is worsened
Solution Approach 1:
The bed frame is segmented into collapsible components that can be disassembled and reconfigured to fit through narrow passages such as corridors and elevators. When transportation is needed, the longitudinal and transverse supports can be folded or separated, reducing the overall dimensions while maintaining the full sleeping space area when assembled in the destination.
Solution Approach 2:
The bed frame incorporates dynamic folding mechanisms that allow it to transition between a large extended configuration for sleeping and a compact collapsed configuration for transportation. The pivot joints enable the frame to adapt its shape and size, providing sufficient sleeping space when needed while allowing easy passage through restricted spaces during relocation.

AI summary
A foldable bed frame structure includes two longitudinal supports, three transverse supports, and a plurality of legs. Each longitudinal support includes a first longitudinal pole and a second longitudinal pole which are symmetrically disposed and have connecting ends connected with each other. Each transverse support includes two transverse poles which are symmetrically disposed and have connecting ends pivotally connected through a U-shaped fixing plate. Free ends of the transverse poles are connected with the first longitudinal pole and the second longitudinal pole through connecting seats, respectively. The legs are pivotally connected to the transverse poles through the U-shaped fixing plate and the connecting seats, respectively. The foldable bed frame structure is convenient for transportation and use.
