Pivoting Stand-Up Aid with Locking Mechanism for Bed Mobility Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility aids for getting up from a bed require users to be in a sitting position, necessitating the use of two separate aids for sitting up and standing up, and often appear unaesthetic as bed gallows.
Innovation Solution
A stand-up aid connected to a bed frame with a pivoting standing rod that can be used to support the user in transitioning from a lying to a sitting position and then to a standing position, featuring a locking mechanism to allow one-handed use and adjustable orientation for different bed configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed rail with triangular handle is used to support sitting up, then the sitting-up process is supported, but the transfer and getting up process cannot be achieved
Solution Approach 1:
The standing rod is designed to perform multiple functions: it can be positioned to support the sitting-up process (extending from head to foot end) and also positioned to support the transfer and getting up process (extending laterally from the bed). This single device replaces the need for separate bed rails and mobility aids, providing universal support for both sitting up and getting up operations.
2Ease of operation
If bed gallows are used as standing aids, then the standing-up process is supported, but the appearance becomes extremely unaesthetic
Solution Approach 1:
The standing rod is designed with a curved, ergonomic handle section that provides both aesthetic appeal and comfortable grip for users. The rod itself has a sleek, modern design that resembles a pole or staff, replacing the traditional gallows structure with a more aesthetically pleasing form while maintaining the necessary functional support for standing up.
3Ease of operation
If a pivoting mechanism without locking is used, then the rod is easy to move, but it cannot provide stable support in fixed positions
Solution Approach 1:
The locking mechanism is designed to engage automatically when the standing rod is positioned in the desired orientation, providing stable support without requiring manual intervention. The mechanism performs the locking action preliminarily, ensuring the rod remains firmly in place once positioned, while still allowing easy repositioning when needed by simply releasing the lock.
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
Enables safe and efficient transition from a lying to a sitting and then standing position using a single aid, reducing the need for multiple devices and enhancing user safety and comfort.
Implementation Method 1
The articulated connection is designed in such a way that a pivoting movement of the standing rod in one direction is possible when using the standing aid to support the sitting-up and/or standing-up process, while a pivoting movement in the opposite direction is blocked or prevented. A spring-loaded detent mechanism may be used to engage with corresponding slots or grooves in the column, automatically locking the rod in place when positioned correctly.

AI summary
A stand-up aid 1 for a person in a bed comprises a column 2 with connecting means for connecting it to a frame part 14 of a bed 15. In addition, the stand-up aid includes a column which, in its position of use, extends transversely to the longitudinal extent of the column 2 and is attached to the upper end of the column 2 is connected and the erecting rod 3 can be pivoted relative to it. A locking mechanism that blocks one pivoting direction of the erecting rod and allows the opposite pivoting direction is inserted into the articulated connection between the erecting rod 3 and the column 2 or the articulated connection is formed by such a locking mechanism.
