Connecting structure of support rods of bedstead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting structures for support rods in bedsteads are prone to instability due to loose fixation, requiring additional installation procedures and multiple positioning grooves, which can lead to shaking and instability.
Innovation Solution
A connecting structure featuring square lateral frame rods with slots and positioning blocks, where each support rod is secured by inserting its ends into positioning groove blocks with first and second positioning portions, providing a stable and quick connection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If support rods are directly inserted into positioning grooves on lateral frame rods, then installation is simple, but the connection becomes loose and unstable
Solution Approach 1:
The positioning block is divided into multiple functional parts: a body portion inserted into the slot, a positioning groove block with positioning grooves for the support rod, and a blocking edge. This segmentation allows each part to perform its specific function - the slot provides insertion path, the positioning grooves secure the support rod, and the blocking edge prevents removal, thereby achieving both easy installation and stable connection.
Solution Approach 2:
The positioning block serves as an intermediary component between the lateral frame rod and the support rod. Instead of directly connecting the support rod to the frame rod, the positioning block mediates this connection by being inserted into the slot of the frame rod and providing positioning grooves for the support rod, thus achieving stable connection while maintaining ease of assembly.
2Ease of operation
If multiple positioning grooves are arranged on lateral frame rods to position support rods, then support rod positioning is achieved, but additional installation procedures are required
Solution Approach 1:
The positioning block combines multiple functions into a single component: it provides the slot insertion interface, contains the positioning grooves for support rod placement, and includes the blocking edge for security. By merging these functions into one integrated component rather than separate features on the frame rod, the positioning capability is maintained while simplifying the installation procedure.
3Ease of operation
If support rods are secured to positioning grooves, then support rod position is fixed, but the support rod becomes easy to loosen and shake
Solution Approach 1:
The blocking edge protruding from the positioning block performs preliminary anti-action by preventing the support rod from being removed or loosened after installation. While the positioning grooves allow the support rod to be inserted and positioned easily, the blocking edge anticipates and prevents the harmful action of loosening, thereby maintaining support stability without compromising ease of initial fixation.

AI summary
A connecting structure of support rods of a bedstead is disclosed. The bedstead includes a bed frame. The bed frame includes support rods arranged and connected between two lateral frame rods. The two lateral frame rods each have a plurality of slots. A positioning block is insertedly connected to each slot. The positioning block includes a positioning groove block. The positioning groove block has first positioning portions therein. Two sides of either end of each support rod are formed with positioning openings for the first positioning portions to be engaged therein. The support rods are easily and quickly connected to the bed frame, and the connection and support is stable.
