Bedrail Mount with U-Shaped Recess to Prevent Rotation and Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedrail mounts require forceful clamping or flexing to attach and detach objects like patient monitors from hospital beds, which can lead to unreliable attachment and potential detachment during transport due to vibrations.
Innovation Solution
A bedrail mount design featuring a U-shaped hook portion with a connecting leg that allows easy coupling without clamping force, utilizing a larger opening than the connecting leg to accommodate bedrails of varying diameters, and incorporating a second U-shaped portion for enhanced grip to prevent rotation and slipping, along with a protrusion for improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If forceful clamping or flexing is used to attach the bedrail mount to the bedrail, then the attachment may be more secure, but the operation becomes difficult and may damage the bedrail
Solution Approach 1:
The opening distance between the first and second legs is designed to be larger than the connecting leg length, allowing the bedrail to pass through easily without requiring forceful clamping or flexing. This parameter change enables the mount to accommodate bedrails of varying diameters while maintaining secure attachment through gravity and friction alone
Solution Approach 2:
Instead of using clamping force to secure the bedrail, the design inverts the approach by making the opening larger than the connecting leg, allowing the bedrail to pass freely and be retained by the weight of the attached object and friction, eliminating the need for forceful attachment
2Adaptability or versatility
If the opening is made larger to accommodate various bedrail diameters, then the adaptability increases, but the structural strength may be reduced
Solution Approach 1:
The first U-shaped portion is designed with an opening distance larger than the connecting leg length, enabling it to universally accommodate bedrails of various diameters and thicknesses without requiring adjustment or forcing, while maintaining structural integrity through the rigid connecting leg
Solution Approach 2:
The design adds a second U-shaped portion with a recess that provides an additional dimension of security by gripping the bedrail, compensating for the larger opening dimension while maintaining overall structural strength and adaptability
3Ease of operation
If the legs are made flexible to enable easy attachment, then the ease of operation improves, but the reliability of attachment during transport deteriorates
Solution Approach 1:
The mount is segmented into distinct functional portions: the first U-shaped portion for easy attachment with its larger opening, the connecting leg for structural support, and the second U-shaped portion with recess for securing during transport. This segmentation allows each part to optimize its function without compromising overall reliability
Solution Approach 2:
Instead of using flexible legs that may fail under stress, the design inverts to a rigid structure where the larger opening enables easy attachment and the weight of the attached object combined with friction and the second U-shaped recess provides secure retention during transport

AI summary
There is provided a bedrail mount (10) for detachably attaching an object (30) to a bed rail (40) of a bed. The bedrail mount comprises a U shaped bracket for positioning over a bedrail. One leg (70) of the U shaped bracket comprises a U shaped recess (20) which, when the bedrail mount rotates, receives the bed rail and prevents the bedrail mount from further rotating and getting detached from the bed rail. The object is attached to the other leg (60) of the U shaped bracket.
