Why I chose Pineapple <3

Pineapple :

Ripened to yellow-gold,

Pointy fellow,

Interesting pattern ...

Sketch

Sketches of the inside and outside of the lampshade.

Did origami prototyping.

pattern : water bom

Form study

After doing some studies on the pine apple I found the mathematical pattern.

Will investigate the possibility of using waffle pattern.

Designing module unites on rhino

First I designed algorithm using grass hoper and then calculated the joints using rhino ( a 3D modeling tool ). Then printed out the 1/5 size model using laser cutter

Selecting Material

Since its a lamp shade, the material has to be soft and safe even when it is falling down. Also it needs to be beautiful as a lamp. Therefore I found a thinner, clearer material which is tracing paper. Bought it at TAKEO.

44*88cm Kurashiko Trasing Paper

Inside structure

The inside resembles the shape of cut pineapples.

I used MDF for the material because it's has low risk of catching fire. I made sure to leave some space from the light to release the heat.

My first prototype made a gap between the lights so I made slight adjustments.

Get ready to laser cut the parts

I converted the rhino data into illustrator data and cut the tracing paper into 45*60cm so it will fit into the laser cutter

Putting it together...

There s 218 intersection... I would take at least 5 hours to weave all the parts together :D This may cause back pain... I used clear tape to loosely construct the whole thing and used hot glue gun to finalize the shape

Hang it up :D

Noe it's up on the room
