Solution Overview
Problem
Existing foldable bed frames lack sufficient rigidity, stability, and are bulky, making them difficult to store and transport due to their non-detachable design.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bed frame is designed as a non-detachable whole structure, then the assembly is simple and structurally complete, but the storage space and transportation costs increase significantly
Solution Approach 1:
The bed frame is divided into multiple detachable components including longitudinal support bars, connecting rods, and a bed board. These segments can be separated for compact storage and reassembled for use, resolving the contradiction between assembly simplicity and storage space requirements.
Solution Approach 2:
The connecting rods are designed with telescopic capability, allowing one rod to be inserted into another. This nesting arrangement enables the connecting rods to occupy minimal space when stored, while providing sufficient length when extended for bed frame assembly.
2Volume of moving object
If the bed frame uses a telescopic connecting rod design, then the storage volume is reduced, but the structural stability and rigidity may be compromised
Solution Approach 1:
The telescopic connecting rods are equipped with locking mechanisms that pre-establish stable connection positions before the bed frame is fully assembled or loaded. This preliminary locking action ensures structural stability is maintained throughout the telescopic adjustment range.
Solution Approach 2:
The locking mechanism is designed to automatically engage and disengage based on the telescopic rod's position, providing self-stabilization without requiring additional fastening operations. This self-service feature maintains structural integrity while preserving the compact telescopic design.
3Ease of operation
If the longitudinal support bars are pivotally connected, then the folding operation becomes quick and easy, but the strength and stability during folding may be insufficient
Solution Approach 1:
The pivotal connections between longitudinal support bars are pre-configured with defined rotation axes and connection points. This preliminary structural arrangement ensures that when folding occurs, the force is distributed along predetermined paths, maintaining strength while enabling easy rotation.
Solution Approach 2:
The connecting rods serve as intermediary elements between the pivotally connected longitudinal support bars. These intermediaries transfer and distribute mechanical forces during the folding process, preventing stress concentration at the pivot points and maintaining overall structural strength.

Implementation Method 1
a ball end leaf spring with a protrusion is disposed in the first alignment hole, the ball end leaf spring is configured to extend out of the first alignment hole under action of an elastic force and retract back into the first alignment hole when subjected to a pressure

AI summary
A bed frame has left, intermediate and right longitudinal support bars, each having two main body sections and an intermediate section connected between two main body sections, via a connecting piece. A first through hole is disposed at an end of each of the main body sections adjacent to the intermediate section. The connecting piece is provided with a second through hole on a side connected to the main body section. When the second through hole is aligned with the first through hole, a support bar pivot shaft can run through the first through hole and second through hole so that the two main body sections can rotate about their respective support bar pivot shafts in a vertical plane relative to the intermediate section. Folding the bed frame is simple and easy to implement, and the bed frame, in a folded state, facilitates transportation and compact storage.
