POSSIBLE WHEEL POSITIONS
Project description: Design an aid for hospital workers
currently most hospital beds have four coaster wheels, this makes moving beds around corners very hard. this project aims at resolving this problem. In the image above different kinds of wheels, their position and their influence on manoeuvrability is shown. -
POSITION OF THE FIFTH WHEEL
The most suitable and cost effective solution appeared to be a 5th wheel which is fixed in the forward direction. This 5th wheel now becomes a pivot point. In the image above different positions of a 5th wheel are explored. -
PRODUCT RENDER
The design is a universally mounted 5th wheel. It can be clamped on 80% of modern hospital beds in the Netherlands. The pedals on the sides provide the possibility to lift the wheel. This is useful when a bed has to be moved sideways. -
GRAPH OF THE RESULTS
To test the the 5th wheel a userpanel was formed. The participants had to complete a circuit one time with and one time without the 5th wheel (4 participants started with, the other 4 started without the 5th wheel). Y = time in seconds, X = number of participants (9th is the avarage). The avarage time difference was 12.84 seconds, a 20% improvement.
