My object is paper fan which can be opened or closed. When it’s fully opened, it can be ideally seems a semicir-cle, so a protractor and a straight scale rule are used to meansure this object.

Bone & SKINPaper fan has a very strong characteristics. firstly, it is very elastic: because the surface of a paper fan is made of folded paper, It gives a large potential to increase the surface.
Secondly, no matter how a paper fan changed it’s shape, it’s always relates with curve.
Thirdly, is about bone & skin. In Chinese or Japanese history, the handle of paper fan usually made by tim-ber which is a common material with very strong abil-ity to stretch. The paper fan I got from store has a maximum open angle - 130 degree, if the angle is over 130 degree, the fan will be broken.

Decomposition Diagram
If we think about this semicircle shape more simplely, we can regards it’s just like radioactive rays that have lots of directions rather than always point on one direction.I think this kind of shape is more flexible and has more advantages than a regular shape. For example, a rectanglar desk will have sharp edges and people can only sit on four direction while people can sit wherever they like with a curve shape desk and can communciate more easily.

Expansion Diagram
The mechanism inside the paper fan is very simple but useful. A similar theory is called “Torque”.By simlply apply a push or a pull force to rotate an object but still make them in balanced position, a twist force is developed through the action. There’s a little fixed connection in the paper fan’s structure, it helps to apply a equal force to both ends in order to make sure this paper fan can work correctly. Also, this theory can used in every deisgn of architectures area,even in fashion design as well.
