Foldable Bed Frame with Sliding Sleeve Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable bed frames lack sufficient rigidity, stability, and flexibility, making them bulky and inefficient for storage and transportation, as they cannot be easily disassembled or reconfigured to different sizes.
Innovation Solution
A bed frame design featuring sliding sleeves and connecting rods that allow for easy folding and unfolding, with a mechanism of sliding sleeves along an intermediate support bar to change the configuration from a collapsed to a deployed state, and incorporating pin holes and elastic pins for locking positions, enabling quick and effective folding and reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bed frame is designed as a fixed whole structure, then the manufacturing and assembly are simple, but the storage space requirement is large and transportation cost is high
Solution Approach 1:
The bed frame is divided into multiple independent modules including head section, foot section, and intermediate sections that can be detached and reconfigured. This segmentation allows the bed to be folded into a compact form for storage while maintaining structural integrity during assembly and use.
Solution Approach 2:
The bed frame incorporates movable connecting structures with sliding sleeves and connecting rods that enable dynamic transformation between deployed and collapsed states. The sliding mechanism allows smooth transition and compact folding without compromising the strength and stability of the fixed structure when in use.
2Adaptability or versatility
If the bed frame uses traditional folding mechanisms, then the structure can be collapsed, but the rigidity and stability are insufficient
Solution Approach 1:
The bed frame is divided into multiple rigid modules (head section, foot section, intermediate sections) connected by folding mechanisms. Each module maintains its structural integrity and rigidity independently, while the connections allow controlled folding motion.
Solution Approach 2:
Sliding sleeves move along guide rails to control the folding motion of connecting rods, providing a controlled and stable folding mechanism. The sliding mechanism ensures smooth transitions while maintaining structural stability during both deployed and collapsed states.
3Ease of operation
If the bed frame is designed for easy folding, then the storage is convenient, but the strength and weight-bearing capacity are reduced
Solution Approach 1:
The bed frame consists of multiple rigid modules that maintain structural strength independently. The modular design allows easy folding through standardized connections while each module retains its load-bearing capacity.
Solution Approach 2:
The sliding sleeve mechanism provides controlled folding motion that maintains structural integrity during the folding process. The connecting rods and sliding sleeves work together to ensure smooth folding without compromising the strength of the overall structure when deployed.
4Device complexity
If the bed frame lacks disassembly capability, then the structure is simple, but the flexibility for different usage scenarios is limited
Solution Approach 1:
The bed frame is divided into detachable modules that can be easily assembled and disassembled. The standardized connections between modules maintain structural simplicity while enabling flexible reconfiguration for different usage scenarios such as full bed, half bed, or storage mode.
Solution Approach 2:
The sliding mechanism enables dynamic reconfiguration of the bed frame structure. The sliding sleeves can move to different positions along the guide rails, allowing the bed to be transformed into various configurations while maintaining structural integrity and simplicity.

Function Achieved in This Case
The design allows for a compact storage footprint, improved strength and stability, and the ability to bear larger weights in both deployed and collapsed states, meeting various user demands by simplifying the folding process and enhancing usability.
Implementation Method 1
a pin is disposed in each of the pin holes, and the pin is configured to extend out of the pin hole under the action of an elastic force and retract back into the pin hole when being subject to a pressure

AI summary
A bed frame has a left longitudinal support bar, a right longitudinal support bar and an intermediate longitudinal support bar, two sliding sleeves slidably disposed on the intermediate longitudinal support bar, wherein each of the sliding sleeve is provided with a bracket. The bed frame further comprises four connecting rods connected between the left longitudinal support bar or right longitudinal support bar and the intermediate longitudinal support rod, one end of each of the connecting rods is pivotally connected to the left or right longitudinal support bar, the other end is pivotally connected with the bracket so that the end of the connecting rod mounted on the bracket moves along with the sliding sleeve. The bed frame is simple and easy to fold and un-fold, while providing improved strength and stability.
