Foldable Medical Bed Frame for Stable Assembly on Uneven Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable medical beds are often unstable and difficult to assemble, making them unsuitable for emergency situations where portable and adequate sleeping facilities are needed, especially on uneven terrains.
Innovation Solution
A foldable medical bed design featuring a stable center base with adjustable head and foot sections, supported by a main frame with pivotally connected legs and a flexible webbing material, allowing for easy transportation and assembly on uneven surfaces while providing a stable support surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional army-style folding cot designs are used, then the bed can be folded for portability, but the bed becomes unstable and difficult to assemble
Solution Approach 1:
The bed frame is divided into multiple sections including a head section, foot section, and center section that can be independently assembled and folded. Each section has its own support structure, allowing for modular assembly that simplifies the overall assembly process while maintaining stability through distributed support points.
Solution Approach 2:
The bed incorporates pivotally connected sections that allow the head and foot portions to be adjusted relative to the center section. This dynamic configuration enables the bed to adapt to different terrain conditions and user needs, improving stability without compromising portability.
2Weight of moving object
If the bed is designed for portability with folding components, then it can be easily transported, but it becomes difficult to assemble and unstable on uneven terrain
Solution Approach 1:
The folding bed is segmented into distinct modular sections (head, foot, center) that can be separately manufactured, transported, and assembled. This segmentation reduces the complexity of assembling the entire structure at once while maintaining portability through compact folding of each individual section.
Solution Approach 2:
The bed design incorporates self-aligning features and intuitive connection mechanisms that allow the sections to automatically position themselves during assembly, reducing the skill level and time required for assembly while maintaining structural integrity for portability.
3Adaptability or versatility
If the head and foot sections are made adjustable for patient comfort, then patient support is improved, but the structural stability and ease of assembly are reduced
Solution Approach 1:
The head and foot sections are pivotally connected to the center section, allowing them to be dynamically adjusted to different angles and positions. This dynamic design provides patient comfort and adaptability while using simple pivot connections rather than complex mechanical adjustment mechanisms, thereby limiting the increase in structural complexity.
4Reliability
If folding legs are added to provide stability on uneven terrain, then stability is improved, but the device becomes more complex and harder to fold
Solution Approach 1:
The legs are integrated as part of the modular sections rather than as separate components. Each section (head, foot, center) has its own integrated leg structure that folds with the section, eliminating the need for separate leg assembly mechanisms and reducing overall folding complexity while maintaining stability on uneven terrain.

AI summary
A folding bed or cot particularly for use as a portable medical bed includes a center base portion connected to a support frame. An adjustable frame has first and second sections that can pivot between a horizontal section and an inclined position. A webbing material or fabric is attached to the adjustable frame and the center base portion of the main support frame to support the patient. The webbing is attached to the side edges of the center base portion to form a planar center portion.
