Clamped Bar for Nursing Trolley Corner Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing care or organization trolleys in hospitals face challenges in securely and simply attaching accessories, particularly due to complex rail systems that can disrupt balance and cause tipping during use.
Innovation Solution
A clamping rail system is integrated into the trolley, attached to corner profiles with a vertically extending undercut, allowing for secure attachment and easy adjustment of accessories without additional components, ensuring stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rail system with columns and brackets is used to attach accessories, then accessories can be attached at different heights, but the device complexity increases and the trolley balance is endangered
Solution Approach 1:
The invention extracts the essential function of height adjustment from the complex rail system and implements it through a simplified clamp mechanism that attaches directly to the trolley frame at different heights without requiring columns, brackets, or other intermediary components
Solution Approach 2:
The clamp is designed to attach accessories at multiple heights along the trolley frame, making a single simple component capable of performing the function previously requiring an entire rail system with multiple components
2Adaptability or versatility
If a rail system with numerous components is used, then accessories can be attached, but the trolley balance is endangered and it may tip over during quick turns
Solution Approach 1:
The invention removes the disturbing rail system components that endangered trolley balance and retains only the essential accessory attachment function through a simplified clamp that attaches directly to the frame
Solution Approach 2:
The clamp is positioned locally at specific attachment points on the trolley frame, distributing the accessory weight at optimized locations that maintain trolley balance while providing the necessary attachment capability
3Strength
If a carrying handle is firmly attached through two blind holes, then the handle is securely fixed, but several objects cannot be attached at different heights
Solution Approach 1:
The clamp is designed to attach at multiple heights along the trolley frame, making a single component capable of providing both secure attachment (through the same blind hole technique) and height adjustment versatility
Solution Approach 2:
The system transitions from a fixed single-point attachment (carrying handle) to a dynamic multi-point attachment system where clamps can be positioned at different heights along the frame to accommodate varying accessory requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamping rail system enables secure attachment of accessories up to 10 kg, maintains balance, and allows for easy height adjustment and alignment, improving usability and safety by providing a strong frictional force and adjustable attachment points.
Implementation Method 1
The clamping element (20) has a lever element (22), wherein a lever arm (26) of the lever element has a projection (12) which engages in the undercut (9) and can be connected in a form-fitting manner to the corner profile (8)
Implementation Method 2
With the form-fitting connection, there is a fairly large frictional force on the contact surface between the clamping rail and the care or organization trolley

AI summary
The invention relates to a care or organizational trolley (100) with a clamping rail (10) for attaching accessories to the care or organizational trolley, wherein the care or organizational trolley is rectangular in plan view with at least slightly rounded corners. The care or organizational trolley is provided to have corner profiles (8), at least one of which has a vertically extending undercut (9) that extends, in particular, to an upper surface or a worktop of the care or organizational trolley. The clamping rail (10) has a clamping element (20), a counter-support element (30), and a connecting bracket (40) that connects the clamping element to the counter-support element and to which the accessory can be attached or suspended.The clamping element (20) can be positively connected to the corner profile (8) at the vertical undercut (9), and the clamping rail (10) can be fixed to and detached from the care or organization trolley (100) by the clamping element (20). The clamping rail can be fixed at any point on the vertical undercut (9) and at a corresponding horizontal point on an adjacent corner profile (8).
