Swivel Lift Grab Bar With Adjustable Arc Transfer Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a swivel lift grab bar that allows users to lift their body from one location and transfer it to another along an arc, which is not effectively addressed by existing technologies such as handrails and support poles designed for recreational vehicles and elderly assistance.
Innovation Solution
A swivel lift grab bar with an angled support member, bottom and top legs, pivot brackets, and optional features like a double knee support, grab cover, and adjustable mechanisms, which can be mounted on various support structures like moveable or rigid poles, enabling users to pivot and lift along an arc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed handrail is used, then it provides stable support, but it cannot assist users in lifting and transferring their body between locations
Solution Approach 1:
The grab bar is designed with pivot brackets that allow it to rotate dynamically between a first position (when user approaches) and a second position (when user is transferred). This dynamic capability enables body lifting and transfer assistance while maintaining structural support, resolving the contradiction between ease of operation and device complexity.
2Adaptability or versatility
If a telescoping support pole is used, then it provides adjustability for different heights, but it increases device complexity
Solution Approach 1:
The support pole incorporates telescoping sections with locking mechanisms that allow height adjustment. This dynamic adjustability enables the device to adapt to different user heights and installation locations, providing versatility while managing the inherent complexity through standardized telescoping mechanisms.
3Ease of manufacture
If the grab bar is mounted directly to the wall, then it simplifies installation, but it reduces adaptability to different support surfaces
Solution Approach 1:
The mounting system is designed with multiple mounting options including wall-mounted brackets, floor-standing bases, and ceiling-mounted supports. This universal mounting capability allows the grab bar to be installed on various support surfaces (walls, floors, ceilings) while maintaining installation simplicity through standardized mounting hardware for each type.

AI summary
An adjustable swivel lift grab bar includes an angled lift member and an adjustable bottom leg. The adjustable bottom leg allows angular adjustment of the angled lift member. The adjustable bottom leg includes a top leg, a bottom leg and a clamping knob with plunger. One end of the top leg is pivotally retained by a pole and the clamping knob is retained in the other end. The bottom leg includes a plurality of holes to receive the plunger of the clamping knob. One end of the bottom leg is attached to a bottom of the angle lift member. A top attachment bracket is secured to a top of the angled lift member for pivotal retention on a pivot post secured to a wall, a floor mounted pole, a double flange pole or a moveable support pole. Rotation of the angled lift member may be braked or motorized.
