Solution Overview
Problem
Existing collapsible bed frames are lightweight, compromising stability and resistance to compression in the expanded state, necessitating an improvement in construction for enhanced stability and portability.
Innovation Solution
A multifunctional collapsible bed frame design featuring side bed frames with collapsible units hinged to transverse boards through specific hinge elements, allowing transformation between expanded and collapsed states, and incorporating regions on the side plates and transverse boards that protrude outward for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight materials are used for portability, then portability is improved, but stability and resistance to compression in the expanded state deteriorate
Solution Approach 1:
The side plates are designed with a protruding first region and a recessed second region, creating local variations in thickness and material distribution. The first region (protruding) provides enhanced stability and compression resistance at critical locations, while the second region (recessed) reduces overall weight. This local quality differentiation allows the structure to maintain portability while improving stability where needed.
2Weight of moving object
If lightweight materials are used for portability, then portability is improved, but resistance to damage by compression in the expanded state deteriorates
Solution Approach 1:
The protruding first region on the side plates is specifically positioned to provide enhanced compression resistance at critical load-bearing locations. By concentrating material in the first region and reducing it in the second region, the design optimizes the strength-to-weight ratio, providing necessary compression resistance while maintaining overall lightweight construction for portability.
3Stability of the object's composition
If complex construction is used to improve stability, then stability is improved, but ease of manufacture and assembly deteriorates
Solution Approach 1:
The side plates are segmented into distinct first and second regions with different thicknesses, allowing each region to be optimized for its specific function. The protruding first region provides structural stability, while the recessed second region reduces weight. This segmentation enables simplified manufacturing processes and easier assembly compared to complex multi-component designs, as the stability enhancement is achieved through geometric variation rather than additional parts.

AI summary
The present invention provides a collapsible bed frame and a collapsible bed. The collapsible bed frame includes two side bed frames and a plurality of transverse boards, and the plurality of transverse boards are spaced between the two side bed frames. Each side bed frame includes a plurality of collapsible units, hinged to the transverse boards through first hinge elements, and a second hinge element is provided in a middle portion of each collapsible unit, so that the collapsible bed frame is transformable between an expanded state and a collapsed state. Each collapsible unit includes a first side plate and a second side plate. A front surface of the first side plate or the second side plate includes at least a first region and a second region, and the first region protrudes outward relative to the second region. According to the collapsible bed provided in the present invention, the first region on the first side plate or the second side plate protrudes outward relative to the second region. In this way, the stability of the collapsible bed frame in the expanded state can be enhanced.
