Collapsible Bed Frame with Protruding Regions for Enhanced Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible bed frames are lightweight and lack stability and resistance to compression in their expanded state due to insufficient mechanical strength, compromising their ability to support the platform effectively.
Innovation Solution
A multifunctional collapsible bed frame design featuring side bed frames with collapsible units hinged to transverse boards through specific hinge elements, where the side plates have protruding regions for enhanced stability, and a collapsible bed board system with offset rotary portions for easy transformation between states, along with support elements for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lightweight material is used for collapsible bed frames to improve portability, then ease of operation is improved, but strength and stability deteriorate
Solution Approach 1:
The bed frame is divided into multiple collapsible units (first collapsible unit, second collapsible unit, third collapsible unit) that can be segmented and folded independently. Each unit contains lateral plates, longitudinal plates, and connecting elements that can be separated and reconfigured, enabling the frame to be collapsed for portability while maintaining structural integrity when assembled.
Solution Approach 2:
The patent employs composite construction by combining multiple material components including plastic materials for the plates, metal fastening elements, and foam padding. This composite approach allows the frame to achieve adequate strength and stability while maintaining relatively lightweight construction for portability.
2Ease of manufacture
If unit thickness foot plates are used to simplify construction, then ease of manufacture is improved, but strength deteriorates
Solution Approach 1:
Instead of increasing plate thickness in one dimension, the patent adds structural elements in additional dimensions by incorporating longitudinal plates that extend between lateral plates, creating a three-dimensional framework. This multi-dimensional structuring provides enhanced mechanical strength without requiring thicker individual plates, maintaining ease of manufacture.
Solution Approach 2:
The support structure is segmented into multiple components (lateral plates, longitudinal plates, connecting elements) rather than using single thick plates. This segmentation allows each component to be thin and easy to manufacture while the assembled configuration provides the necessary mechanical strength through distributed load bearing.
3Adaptability or versatility
If collapsible units with hinge elements are added to enable transformation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The collapsible units are designed with nested components where longitudinal plates are positioned within spaces defined by lateral plates, and connecting elements nest within alignment features. This nested arrangement enables the complex transformation function while keeping individual components relatively simple and the overall structure compact when collapsed.
Solution Approach 2:
The hinge elements and connecting structures serve multiple functions: they enable transformation between expanded and collapsed states, provide structural support when assembled, and include alignment and fastening features. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while achieving adaptability.

AI summary
The present invention provides a collapsible bed frame (10) and a collapsible bed (100). The collapsible bed frame (10) includes two side bed frames (11) and a plurality of transverse boards (30), and the plurality of transverse boards (30) are spaced between the two side bed frames (11). Each side bed frame (10) includes a plurality of collapsible units (110), hinged to the transverse boards (30) through first hinge elements (12), and a second hinge element (13) is provided in a middle portion of each collapsible unit (110), so that the collapsible bed frame (11) is transformable between an expanded state and a collapsed state. Each collapsible unit (110) includes a first side plate (111) and a second side plate (112). A front surface of the first side plate (111) or the second side plate (112) includes at least a first region (113) and a second region (114), and the first region (113) protrudes outward relative to the second region (114). The collapsible bed (100) includes, the first region (113) on the first side plate (111) or the second side plate (112) protrudes outward relative to the second region (114). In this way, the stability of the collapsible bed frame (10) in the expanded state can be enhanced.
