Modular Nursing Bed Frame With Telescopic Length Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nursing beds lack versatility and flexibility to accommodate varying patient conditions and sizes, as they are not easily modifiable or adjustable in terms of length and height.
Innovation Solution
A bed design featuring telescopic mattress side rails and adjustable transversal frames with interchangeable attachment means, allowing for extension of the bed length and height adjustment, along with locking mechanisms that secure the frame without additional actions, and articulated sections for different patient positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bed is designed with fixed length and structure, then manufacturing is simpler, but adaptability to different patient conditions and sizes is reduced
Solution Approach 1:
The bed is divided into modular components including a main bed frame and a separate extendable mattress support frame that can be attached or detached. This segmentation allows the bed to be configured for different patient lengths and conditions while keeping each module relatively simple in design.
Solution Approach 2:
The mattress support frame is designed to be extendable and adjustable, allowing dynamic reconfiguration of the bed length and configuration based on patient needs. The frame can be extended to accommodate longer patients or collapsed for standard use, providing adaptability without requiring a completely different bed for each scenario.
2Ease of operation
If attachment means are designed to be easily releasable, then ease of operation is improved, but reliability of locking may be compromised
Solution Approach 1:
The attachment system utilizes gravity-actuated locking means where the locking action occurs automatically when the mattress support frame is lowered into place. The gravitational force on the frame causes the locking mechanism to engage without requiring manual intervention, providing both ease of operation and reliable locking through the natural weight of the components.

AI summary
The present invention relates to a bed comprising two first longitudinal rails, telescopic mattress side rails, two transversal frames, attachment means between said transversal frames and said two first longitudinal rails for releasable attachment, and a mattress extension frame arranged with similar attachment means and connectable between one transversal frame and said two first longitudinal rails for extending the length of the bed.
