There are different ways to measure the angle. I just simply break the fabric and use the protractor to measure the angle, but we could also use the Pythagorean theorem to calculate the angle.

Analysis
Hinge Joint
Pin Joint
This umbrella is an example of skin and bone structure.
90mm 155oC
Its waterproofed fabric is the skin and the steel structure is the bone.
45oC
The fabric is attached to its steel and they are working together; protects people from getting wet or sunburn. They are working as a whole system. Become Useless if without one another. Pin joint controls the height of the fabric, and hinge joints control the size of the fabric spread.

Digital Model
The umbrella is consisting of 8 same pieces, so I just need to build one of them and rotate to the right angle (360/8=45 degree).

In Class Activities
In class, we tried to build a skin and bone system in order to create a personal safety zone for our model. Basically, the bones form an outer frame all over the head, front, and back. The red ‘skin’ is the extension of the bone system, this creates a further protection.

Sketch Model
The frame of this model is made by metal wire, they are actually in the same repeated pattern and I’ve used pin joint to connect them. I choose to put the skin under the bone system because I want to show the whole structure of the bones. What’s more, I want to declare that in a skin and bone system, it is not necessary to make the skin on top. Skeletons can also be exposed on the outside. 8
Sketch Design #1 Cactus, expand and thorn
The ‘Clothes’ can form thorn when people approached, in order to maintain the appropriate personal safety zone.
The ‘Skin’ is covered on the surface of the person’s skin; this can also have fixed the bones which formed outside. The ‘bones’ are loose and straight in the normal situation, it will form a sharp triangle in order to protect the safety zone.

Sketch Design #2 Lantern, shell and embrace
The ‘bones’ formed a shell-like object wrapped up with each other, each shell covered by a separate skin; with different lights inside. Shells are connected with wires and been embraced all over the person’s body to protect each individual position that specifically wants to been protected.

Sketch Design #3 Spider dance and spread
This looks like a small object; however, it can be shoot out when facing threat. It can throw to any direction and formed a huge thing which like a spider net in order to prevent danger or inconveniences in 360 degrees. The size of the ‘net’ can also various depends on the person’s wishes. Normally the spine of the net is overlapping with each other, that’s how it can change its length. The ‘net’ is the bone structure in this design and the skin is the cover to collect these bones.
