Bed frame connecting structure and bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed frame mounting methods using screws and square insertion tabs result in complex structures with gaps and poor stability, leading to wobbling during use.
Innovation Solution
A bed frame connecting structure featuring a support leg with a clamping member composed of side plates forming a wedge-shaped insertion slot and a connector with a positioning groove, allowing the connecting rod to fit tightly without wobbling, using a pentagonal cross-section design and right-angle sector shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional square insertion tabs are used to connect bed frame components, then assembly is simple, but gaps are formed between the insertion tab and slot causing wobbling and poor stability
Solution Approach 1:
The patent applies asymmetry by changing the insertion slot from a conventional square cross-section to a pentagonal cross-section. This asymmetric shape creates a non-uniform fit between the insertion portion and slot, eliminating gaps that cause wobbling. The pentagonal geometry ensures that the connecting rod cannot rotate or shift within the slot, providing stable connection while maintaining simple assembly through the insertion method.
2Reliability
If screw mounting is used to secure connecting rods, then connection stability is improved, but structure becomes complex and assembly steps become cumbersome
Solution Approach 1:
The patent extracts the fastening function from the connecting rod assembly by providing a separate clamping member that is fixed to the support leg. This clamping member with its pentagonal insertion slot handles the stabilization function, allowing the connecting rod to be simply inserted without requiring integrated screw mechanisms or complex fastening structures in the rod itself.
Solution Approach 2:
The patent segments the connection system into distinct functional components: the support leg with clamping member provides structural support and stabilization through the pentagonal slot, while the connecting rod with insertion portion provides the connecting function. This segmentation allows each component to be optimized independently, achieving stable connection without complex integrated structures.
3Productivity
If conventional insertion methods are used, then assembly is quick and simple, but gaps between insertion tab and slot cause wobbling
Solution Approach 1:
The pentagonal cross-section creates an asymmetric fit that eliminates gaps while maintaining the quick insertion advantage. The shape allows the insertion portion to be guided into the slot easily, and once inserted, the non-circular geometry prevents rotation and shifting, providing stable connection without requiring complex fastening operations that would slow down assembly.

AI summary
A support leg and a connecting rod in the present invention are fixed together through fitting between an insertion portion and a wedge-shaped insertion slot. When subjected to external omnidirectional pressure, the insertion portion can go lower and fit tighter, making a gap smaller without wobbling, thus allowing for a simple structure with good stability.
