Measured Drawings

To complete these drawings, I used a number of different methods to measure the object. I found it helpful to photosgraph my object from the top and side views and trace over these photographs. I also took a camera roll of the object in use to illustrate its inflated state and ability to extend in length. However, this method was not appplicable to all drawings. For the section drawing, I used a ruler to measure the internal structure within the object and translated this onto the page at a scale of 1:1. The head of the object was semi-transparent in front of a lamp, so I was able to measure the internal structure without physcially cutting through the object.

The wire is curled up at normal state, stuck onto the surface of the skin. The wire straightens when air forces the skin apart. While the skin forms the main structure when inflated, the wire defines and articulates the shape of the object.
The end of the wire has the strongest curl to prevent straightening and inflation which leads to the loss of air.

SECTION 1:1 Wind is pushed into the head chamber of the party blower, forced through a narrowed channel, which forces all the wind energy into the skin of the object, inflating it. While the wire spine is formally the “frame� of the object, the spine by itself curls up. it is the skin which contains the air and allows for inflation and the resulting three-dimensional volume. Hence, there is almost an inverse of skin and bone/ frame.

Sketch Design #1 ARM SUPPORT/MOVEMENT/INFLATION/RESTRAINT/SPRINGS
Key areas that need support in order to hold the arm in place and prevent your hand from slipping.
Borrowing the swirl shape for the design. The design in its inflated state should be able to hold the arm in place and contrain movement.
The swirls at the bottom of the elbow should stop the elbow from sliding along the desk.
The sharp, protruding springs on this design idea prevents people sitting next to you from getting too close. It also intimidates. 10
Sketch Design #2 SUPPORT/FACE SHIELD/CUSHION
The springs interact with the surface and retracts or slides along the surface until it reaches a stable point. The sides of the head and shoulders are key areas that need support. The neck also needs to be supported.
How does this respond to your personal space?
This design idea partially covers the user’s face from view. The sharp swirls act as a signal of strength and agression to deter people from approaching.

This design idea addresses the vulnerability I feel when my back and shoulders are exposed when I am lying in this position - face down and sleeping on the desk. 12
