Connecting structure and bed frame having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable bed frames are expensive to produce and difficult to fold, particularly when lateral or longitudinal bar units are made of stacked bars, due to their welded construction.
Innovation Solution
The design incorporates upper and lower receptacles with pins and holes in the longitudinal and lateral bar units, allowing for removable and rotatable connections that enable flexible and stable folding, using notches and tubular pieces for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If lateral and longitudinal bar units are welded together, then the bed frame structure is strong and stable, but the manufacturing cost increases and the frame becomes difficult to fold
Solution Approach 1:
The bed frame is divided into separate modular components (lateral bar units and longitudinal bar units) that can be independently manufactured and assembled. Each unit is a discrete piece that connects to others through receptacles and fasteners, enabling cost-effective production while maintaining structural integrity through modular assembly rather than welding entire frames together.
Solution Approach 2:
The connection system transitions from fixed welded joints to dynamic, removable connections using receptacles, pins, and fasteners. This allows the frame to be disassembled and reconfigured for folding and storage, while the fastener mechanisms provide secure attachment during use, balancing structural strength with folding capability.
2Stability of the object's composition
If lateral and longitudinal bar units are welded together, then the bed frame structure is stable, but the frame becomes difficult to fold
Solution Approach 1:
The connection system transitions from fixed welded joints to dynamic, removable connections using receptacles, pins, and fasteners. This allows the frame to be disassembled and reconfigured for folding and storage, while the fastener mechanisms provide secure attachment during use, balancing structural stability with folding capability.
Solution Approach 2:
Receptacles serve as intermediary components that facilitate connections between lateral and longitudinal bar units. These receptacles with pins and fasteners act as mediators that enable both stable connection during use and easy disconnection for folding, eliminating the need for permanent welded joints.
3Adaptability or versatility
If stacked bars are used for lateral or longitudinal bar units, then the frame can be folded, but the welding process makes folding difficult
Solution Approach 1:
The bar units are segmented into separate lateral and longitudinal components with standardized connection interfaces. This segmentation allows stacked bars to be easily assembled and disassembled without welding, enabling folding capability while simplifying manufacturing through modular assembly.
Solution Approach 2:
The connection system uses removable fasteners and pins instead of permanent welds, allowing the stacked bar units to be dynamically assembled and disassembled. This provides the adaptability needed for folding while reducing manufacturing complexity compared to welding stacked bar configurations.

AI summary
A bed frame includes outer lateral and longitudinal bar units, each having a first end and a second end. Each of first, second, third, and fourth longitudinal bar units includes an upper longitudinal bar and a lower longitudinal bar. The first ends of the first and second longitudinal bar units are rotatably connected with each other. The first ends of the third and fourth longitudinal bar units are rotatably connected with each other. Of each respective longitudinal bar unit, the second end of the upper longitudinal bar is movably connected with the first or second end of a corresponding lateral bar unit, and the second end of the lower longitudinal bar is fixedly connected with the first or second end of the corresponding lateral bar unit.
