I measured the fan by laying it out on a piece of paper and marking the outside

points with a pencil, then I measured the points on the paper with a ruler. It was easier to get a correct measure-

ment this way, because the rulers’ stiffness prevented me from getting an accurate measurement directly on the

fan.

section 11:2

As I had two identical fans I cut off the paper from one to expose the ‘skeleton’

of the fan.

section 21:2

To draw the measured fan I took a series of photographs from different angles, scaled them down on the computer,

printed them out, then traced over them.

I decided to use a series of different scales to highlight different aspects of the fan and to accurately portray the

measurements.

pin joint2:1

The 20 wooden slats of the fan are held together on one end by a pin join. The

slats then swivel out by the pin.This diagram shows the motion of the wooden slats over the pin.

This diagram shows a cut through view of the pin and the mo-tion of the wooden slats.

The paper is glued onto the wooden slats and creates tension, when the pa-per is fully extended, or almost flat, that

is as far as the fan can open out. The direction of the fold of the paper also

restricts the fan from only being opened in one direction.

Without the paper between the wood-en slats, there is no tension, there is also

no ‘end’ point, this would create the slats to move freely around the pin joint

360 degrees clockwise or anti-clockwise.
