Folding bedstead and folding bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current folding beds lack sufficient support strength and have a large folded size, leading to discomfort and storage inefficiency due to the absence of U-shaped bed frame tubes and rigid support, causing fabric recess and complex, bulky designs.
Innovation Solution
A folding bedstead with a bed surface support frame and support leg frame featuring U-shaped structures, including intermediate, lateral, and outer leg frames, and rotary connecting assemblies that form a stable triangular fixing structure, providing rigid support and allowing for compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional folding beds use fabric connections without rigid support, then the structure is simple and flexible, but the support strength is insufficient causing fabric recess and discomfort
Solution Approach 1:
The bed frame is divided into multiple modular components including head frame, foot frame, connecting rods, and support legs. Each segment can be independently folded and reassembled, providing rigid support while maintaining folding capability. The segmentation allows the structure to achieve both strength and portability.
Solution Approach 2:
The patent combines metal tubes (for rigid support) with fabric (for comfort and flexibility). The metal frame provides structural strength while the fabric covering maintains user comfort. This composite approach resolves the contradiction between rigid support and flexibility.
2Strength
If folding beds use many tubes and complex structures, then the support strength is improved, but the folded size becomes large occupying more storage space
Solution Approach 1:
The support legs and connecting rods are designed to nest within each other when folded. The outer leg frames contain the lateral leg frames, which in turn contain the intermediate components. This nesting arrangement minimizes the folded volume while maintaining all necessary support structures for strength.
Solution Approach 2:
The patent employs dynamic folding mechanisms where the leg frames and connecting rods can transition between extended (for support) and retracted (for storage) positions. This dynamic capability allows the structure to provide full support strength when needed while minimizing footprint during storage.
3Stability of the object's composition
If folding beds use traditional connection methods, then the structure is simple, but the stability is insufficient causing fabric recess after long-term usage
Solution Approach 1:
The connecting rods are pre-configured with connection holes and fastening mechanisms that enable secure attachment to the leg frames before assembly. This preliminary preparation ensures that when the bed is assembled, all connections are immediately stable and rigid, preventing fabric recess from the outset.
Solution Approach 2:
The patent introduces connecting rods as intermediary elements between the leg frames and the bed frame. These rods act as mediators that distribute and transfer loads, enhancing the overall structural stability and preventing fabric deformation while maintaining a relatively simple connection system.

AI summary
A folding bedstead and a folding bed comprising same. The folding bedstead comprises a bed surface support frame and a support leg frame. The bed surface support frame comprises intermediate connecting pieces and support units symmetrically arranged at two ends of the intermediate connecting pieces. Each support unit comprises straight connecting tubes pivoted to the intermediate connecting pieces and a U-shaped bed frame tube pivoted at outer ends of the straight connecting tubes. The bed surface support frame is a closed planar frame in an unfolded state. The leg support frame comprises an intermediate leg frame, lateral leg frames, and outer leg frames, wherein the intermediate leg frame is arranged on the intermediate connecting pieces, the lateral leg frames are arranged on the straight connecting tubes in a folding manner, and the outer leg frames are arranged on the U-shaped bed frame tubes in a folding manner.
