Subject: the normal type of pocket (folding) umbrella for raining weather Manufacturer: Daiso Industries Co, LTD,. (made in China) Designer: the manufacturer Material: cloth polythene (fabric), iron (shaft and rib), plastic (umbrella runner, handle and cap) Manufacturing Processes: the process begins with accurately cutting fabric for the umbrella panels, using chalk and a circlar saw, into tessellated triangles. Frames are then constructed. A push button may be added to the sliding mechanism and the central pole pushed through, with the two sections neatly nailed together to complete the frame Dimensions: 1000mm wide, 600 mm tall

Analysis
When pushing the runner towards the top, the structure of te umbrella stretches horizontally, in the same way as the triangle sketch frame shown on the left. The fabric cloth is neated to the structure in particular point so that the fabric stretches along with the frame.

There are various stainless components form a bone unit of the umbrella frame. They are connected with pin-like joints.
These two highlited parts of the frame are to provide tension force to the iron frame and make sure the structure sttretches up to a particular arh. Without these two “wires�, the frame, especialy the end fo the frame can be very loose and won’t be able to tense teh cloth fully.

Squashed We may get disturbed easily in everyday life. Our personal space may get invaded by glaring, noise, disgusting smell and crowds. This wearable design is stretchable with wire frame acting as the ‘bone’. The skin of this idea uses ‘Folding Technique 1’, which can be stretched and twisted a bit. According to different demands, this ‘cloth’ can be adjusted to different length in different directions. Stretched Stretched by Wires

Sketch Design #2 Embracing, Wings, Squared Skin
Closed (supported with wires) Side Elevation Stretched (Back View) Squashed (Back View) The concept of this idea is to embrace the other to personal space. The skin of this idea is of the second paper folding technique, while the bones are also design in wires to support the skin when it is squashing and stretching. When the system is fully squashed, the ‘cloth’ is an array with squares. When it is stretched, all the squares will get apart and the surface of the skin will get larger.

Sketch Design #3 Rejecting, Defending
Squashed (Elevation)
Stretching on Arms
The concept of this idea is to reject the people or the surroundings that are trying to invade the personal space. The skin of this idea is using the third folding technique. When stretching the skin, small angles appear. The angles are not too sharp so that the skin will not be too aggressive but it is still rejecting others in a certain extent.
