Folding Bed Connection Members to Reduce Bending and Assembly Labor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding beds are labor-intensive to assemble and have unstable structures due to easily bendable bolts, leading to potential damage when lifted.
Innovation Solution
The use of connection members, such as frame and leg connection members, that securely couple bedsteads by integrally formed engaging members and link members, facilitating easy assembly and disassembly while preventing relative movement and bending during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bolts are used to couple bedsteads, then the structure can be assembled, but the bolts are easily bent and the structure becomes unstable
Solution Approach 1:
The connection member is divided into multiple functional segments: engaging members for coupling with bedsteads, link members for connecting engaging members, and reinforcing members for preventing bending. This segmentation allows each component to be optimized for its specific function while working together to solve the overall connection problem.
Solution Approach 2:
The connection member employs a composite structure combining different material properties and structural forms - rigid engaging members for secure coupling, flexible link members for connection, and reinforcing members (such as ribs or gussets) for anti-bending strength. This composite approach creates a connection system that is both strong and resistant to deformation.
2Ease of manufacture
If simple joints are used in folding beds, then the design is simple, but assembly is time-consuming and labor intensive
Solution Approach 1:
Multiple connection functions are merged into a single integrated connection member that combines engaging members, link members, and reinforcing members. This unified component can be installed as one unit, significantly reducing assembly time and labor while maintaining structural integrity and simplicity in the overall design.
Solution Approach 2:
The connection member is pre-configured with engaging members and link members in their proper positions and orientations during manufacturing. This preliminary arrangement allows for quick installation at the assembly site without requiring complex field adjustments or multiple separate assembly steps.
3Ease of operation
If bolts are used to connect bedsteads, then connection is achievable, but the bolts can be easily bent when the folding bed is lifted
Solution Approach 1:
Link members serve as intermediary elements between the engaging members that connect to the bedsteads. These link members transfer and distribute the lifting forces, preventing direct bending stresses on the connection points while maintaining the connection capability between bedsteads.
Solution Approach 2:
Reinforcing members such as ribs or gussets are incorporated into the connection member design before assembly to provide preemptive structural support. These reinforcing elements are positioned to counteract bending forces that will occur during lifting, effectively cushioning the connection structure against deformation before the bending stress is applied.

AI summary
A folding bed includes first and second bedsteads and one or more connection members coupling the first and second bedsteads. A connection member can be a frame or a leg connection member. A frame connection member includes first and second vertical end portions to removably couple adjacent peripheral bars of the first and second bedsteads. A leg connection member includes first and second engaging members to removably couple adjacent legs of the first and second bedsteads. The one or more connection members reduce the risk of bending the folding bed and assist in stabilizing the folding bed when in use.
