Detailed elevation
Front elevation of Half stretched folding frame Scale 1:2 on A3
Methods of measuring: This object can be separated as two parts Mirror and folding steel holder for the Mirror. I took some photos for plan and elevation as reference for measurement. And then i found the movement of the object. Firstly, I measured Mirror which is a circle,and i found its diameter is 170mm. And then i measured the supporting steel’s length which was bit difficult. Two rulers perpendicular to each other and i got the length is 120cm. Secondly, i measured the folding holder by three different expanding form, Folding together, half stretched and full stretched. When it stretches, the length is overing the A3 paper, thus i used the scale of 1:2 to draw it. SCALE 1:1 ON A3

Analysis This photo shows the elevation of the holder when it is full folding together. Pin joints are very important for the holder’s movement. If other joints use on the holder, it won’t work as good as pin joints. when it is folding like this, it has the shortest width(extension distance), but it has the highest strength.
This photo shows half stretched holder. The angle between two leaves are about 90 degrees. It has much longer extension distance than full bolding together, but the strength is lower than that.
I am not sure does this mirror has bolding on it or not. But pin joints allows the mirror to rotate.
This photo shows full strectched holder. The adjacent leaves are approaching 180 degrees. The stregnth of the holder is the lowest at this moment.

The logic of the folding holder is that one side is fixed and the other side is moveable, and pin joints allow the holder to move. When it stretches, the left end goes up, the right side end goes down. They all stay on the horizontal line while moving. However, the bottom line will rise up and getting closer to the top line.

First step: i cut tthree different kind of balsa and they have same shape with the leaves of the mirror holder, but different length. Their length are 145mm,135mm and 70mm. i made 6 pieces of blasa for each length. Second step, i use needle and cotton wire to seam them together.

Sketch Design #1 Arm, shoulder protection, Helmet, hidden thorn,
What is your idea? [Maximum 5 key words]
How does this respond to your personal space? The idea is from my precedent design. For this one, i expected it to be an arm for protecting personal space. For myself, my sensitive part of body are shoulder and back. Thus i design this hidden thorn mail. all sticks will lift up when it is necessary and protect prosonal space.

Sketch Design #2 Heart exposed, face covered, surround.
What is your idea? [Maximum 5 key words]
How does this respond to your personal space? The material for this idea are 2mm hexagons cardboard and 2mm heptagons cardboard. The photo above shows the personal space model we made in week 2 tutorial and it gave me inspiration for the new design. However, the precedent one covered the chest up. For my new design, i choose to expose half of chest (expose the heart) which refers to friendly, opening heart to everyone.

Sketch Design #3 expansion,contraction, surround,
What is your idea? [Maximum 5 key words]
How does this respond to your personal space? This design is able to expansion and contraction. When you meet your friend, you are able to contract it to close to your body or set up a closer distance to your body. When you are on the public transport, you can use it to keep people away from your personal space.
