Mounting structure for bedstead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for bedsteads, which rely on welding metal parts, increase labor and manufacturing costs and pose risks of injury during assembly.
Innovation Solution
A mounting structure for a bedstead that connects side rails and cross rails using a snap-fit mechanism with a connecting member featuring U-shaped grooves and holes, allowing for quick and detachable assembly without welding, facilitated by an aligning structure for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect side rail and cross rail, then the connection strength is improved, but labor cost and manufacturing complexity increase
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a mechanical snap-fit connection system. The connecting member includes a body with a first U-shaped groove for clamping the side rail and a second U-shaped groove for clamping the cross rail, eliminating the need for welding operations while maintaining connection strength.
Solution Approach 2:
The connecting member is divided into multiple piece bodies (first piece body, second piece body, third piece body, and optionally fourth, fifth, sixth piece bodies) that are connected to form U-shaped grooves. This segmentation allows for easier manufacturing and assembly while achieving the same connection function.
2Strength
If welding is used to connect side rail and cross rail, then the connection strength is improved, but safety risks increase due to potential injury
Solution Approach 1:
The patent eliminates welding operations entirely by using a mechanical snap-fit connection system. The connecting member with U-shaped grooves clamps the side rail and cross rail through mechanical force distributed across multiple contact surfaces, avoiding the safety hazards of welding (heat, sparks, fumes) while maintaining connection strength.
3Reliability
If traditional connection methods are used, then assembly is secure, but assembly time and disassembly difficulty increase
Solution Approach 1:
The connecting member incorporates an elastic element that provides dynamic snap-fit action. When the connecting member is inserted into the aligning structure (protruding block and aligning hole), the elastic element deforms and then snaps into place, providing secure assembly quickly. The same mechanism allows for easy disassembly by applying force to overcome the elastic retention.
Solution Approach 2:
The aligning structure with protruding block and aligning hole performs preliminary alignment of the connecting member with the side rail and cross rail before the final snap-fit connection occurs. This preliminary action ensures proper positioning and speeds up the assembly process by eliminating manual alignment adjustments.

AI summary
A mounting structure for a bedstead includes a side rail and a cross rail of the bedstead. The side rail and the cross rail are connected by a connecting member and an inserting member. The connecting member includes a body. The body is provided with a U-shaped groove in which the cross rail is clamped and a first hole located in a middle part of the U-shaped groove. The side rail is provided with a second hole matching with the first hole; and the inserting member is connected to the cross rail after sequentially passing through the second hole and the first hole. The use of the connecting member and the inserting member allows a quick and detachable connection between the side rail and the cross rail, facilitating storage and transportation.
