Pivoting IV Stand Handle for Safer Mobility and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intravenous bag stands with protruding handles pose a tripping hazard for patients and are inefficient for storage due to their bulky design when handles extend beyond the wheelbase.
Innovation Solution
A two-position handle device attachable to intravenous bag stands, featuring a collar, a pivotally connected handle, and a locking mechanism with cylindrical sleeves and tenons, allowing the handle to be easily switched between a horizontal working position and a downward storage position, preventing accidental contact with the stand base and optimizing storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protruding handle is provided on the intravenous bag stand for easy gripping and moving, then the ease of operation is improved, but the stand creates a tripping hazard for patients and becomes bulky for storage
Solution Approach 1:
The handle is designed to be movable between a horizontal extended position (for gripping and moving the stand) and a vertical retracted position (for storage and safety). The handle pivots at the collar member and can be locked in the horizontal position or returned to the vertical position, transforming from a static to a dynamic structure that adapts to different operational needs.
Solution Approach 2:
The handle transitions from extending horizontally (perpendicular to the stand pole) to extending vertically (parallel to the stand pole). This dimensional change allows the handle to provide ergonomic gripping when needed while retracting to avoid tripping hazards and reduce storage footprint.
2Ease of operation
If a protruding handle is provided on the intravenous bag stand for easy gripping, then the ease of operation is improved, but the device becomes bulky and inefficient for storage
Solution Approach 1:
The handle is designed to be movable between a horizontal extended position (for gripping and moving the stand) and a vertical retracted position (for storage and safety). The handle pivots at the collar member and can be locked in the horizontal position or returned to the vertical position, transforming from a static to a dynamic structure that adapts to different operational needs.
Solution Approach 2:
When the handle is in the vertical retracted position, it aligns with and effectively nests within the profile of the stand pole, minimizing the overall volume and footprint of the stand for storage purposes.
3Ease of operation
If the handle is made extendable beyond the wheelbase for better leverage, then the ease of operation is improved, but the stand becomes unstable and difficult to store
Solution Approach 1:
The handle is designed to be movable between a horizontal extended position (for gripping and moving the stand) and a vertical retracted position (for storage and safety). The handle pivots at the collar member and can be locked in the horizontal position or returned to the vertical position, transforming from a static to a dynamic structure that adapts to different operational needs.

AI summary
A two-position handle device for use with a wheeled intravenous bag holder having a vertical pole includes a collar slidably positionable upon the vertical pole. A first member extends from the collar, the first member having a tenon extending therefrom, while a second member connects to the first member, the second member having a tenon extending therefrom. A handle extends from the second member, wherein the handle is positionable between a first downwardly extending position and a second horizontally extending position. To lock the handle in the second position, a cylindrical sleeve slidably disposes over both the tenon of the second member and the tenon of the first member, thereby preventing pivotal movement of the second member relative to the first member, and locking the handle in the second horizontally extending position.
