The umbrella is measured directly on the horizontial surface using measuring tape. And the each side of the umbrella is 370mm, because each side is equal so it is easy to find out the angle between the frame.To measure the angle of umbrella surface, the edge is put on the flat surface and measured from top to the surface. Therefore, from top of umbrella to the edge is 170mm. As the umbrella has two slops, to find out the first slop. I fully opened it and measured the radius and the length from top to that point and do the calculation and find out that is 100mm.

DETIAL OF FULL OPEN UMBRELLA SCALE 1:5
DETIAL OF HALF OPEN UMBRELLA SCALE 1:5
These two detial drawings forces on the single bone structure,and comparing the detial of full open umbrella and half open one. it is easy to find out that member A pushs the whole frame straightly. Therefore, member B, C and D are under compression. And the system applied in umbrella is skin and bone, in it bone fuctions for opening and closing to create a volume, the skin does the cover of the frame. But the reason why umbrella can do this fuction is mainly the joins it used, and that is pin join. It creates the flexibility of routation.

Sketch Model
This sketch model is made by basla wood stick, pins and cling. It is obvisouly that the balsa wood stick and pins form as the bone structure which extante the length and increasing the volume as shown from the image from left to right. And using the pin join gives the sticks space to rotate horizontally relative to where the pin vertically pined into the sticks.

Sketch Design #1 Key Ideas wing left side heart protection
I do this second skin just forced on the top left side of body because our heart is at the left side and most of people are stronger on their right hand side and use it more offen. The front part is not just work as protection but also balance the wing behinde. The wing can also keep others from left side and the back.

Sketch Design #2
Key Ideas Routate Cover both sides
This design covers the top front of the body and the head at the same time. And it can be routateed almost 180 degree, the position of the sink can be stopped at the point you want. It is visiable as the front part goes up and fully self controllable.

Sketch Design #3 Key Ideas
Top cover Space for moving under cover
This design more likes a suit that the person can wear it. The whole skin is the flowing part, from the head to the cover of front then the arm and the back and just going down.The arm part is a huge circle that create a hole and space for arm to move around.
