Assembling Ball Stool

Here is the video on how to assemble the Ball Stool :)

Progress of Final 1:1 Chair in Xanita

This is the collection of photos showing the final progress of the ball chair. It consists of photos of the template and the p rocess of assembling the chair. So glad that it is finally done!

Final Template

After several tryouts of different types of locking, i decided to go on with this one. Although my first aim is to have the chair as a seamless piece without the locking appeared at the surface of the chair, it seemed quite impossible because it won't hold the chair strongly. Therefore, this final locking system will be done from the outside of the chair instead of the inside, thus giving more strength.

Testing Locking System in 1:3 Scale

After my first attempt of 1:1 scale chair failed, I reviewed the locking system and made some changes to it. I changed the template so that it is easier for the parts to join. And
I tried to use another method of locking system, but it's not working really good because of the scale is too small.

First Attempt of 1 to 1 in Xanita

Here is my first tryout using Xanita board in 1:1 scale. After spending few hours i managed to cut the template and V cuts.

Locking System

After that, life gets tougher! assembling the template was so hard. Xanita board is hard to assemble when the angle and measurement is not correct. But I managed to get the first side done.

Trying to lock the parts up

First side assembled

Then, I managed to get both side locked up though not very nicely done. I thought it was really good on my first attempt.




Next, is the inner part of the chair, this part is a supporting role to the chair so that it is strong enough to hold someone weight when it is seated.

When it is done, it is placed in the inside of the chair that I have assembled.

Inner side of the chair

Sadly, some of the angles of the V cuts weren't right and the worst part is that the locking system is not strong enough to hold parts of the chair when it's pulled together. I had to use tape to make it stayed and you can see from below pictures, the locking system is too tight and pulling out.

Here are some photos:

Testing angles and V cut

This is one part of the chair, there are four sides with this type of shape. So, to get the shape i want, i have to make V cuts on each side so that it can fold properly.

Here is my first attempt :

First Attempt

I made the angles too big so all side did not come together closely as you can see there is gap in between.

Here is my 2nd attempt :

Second Attempt

In 2nd attempt I successfully made it :). The V angle was smaller so all side are coming together as one.

Concept Refinement - Outcome

Concept Refinement

From the fourth development, i went back to the previous design, and try to make the reinforcement inside the chair to be stronger, by combining 2 of the 2 interlocking planes. Plus, i modified the shape a bit, by removing the middle part of the stool.

Having the pair of interlocking reinforcement joined together, creates more strength for the chair, and still keeping the shape of the chair as a geometric form. I have decided to go on with this design for the final. :)

Design Development 4

From the Design Development 3, i tried to improve the strength of the chair by generating the shape; punching two of the sides in so that it has some kind of 'Extra strength'.

Outcome of the Trial

Because i made this model out of 3mm cardboard, it is quite hard to do the locking system, because the material is too thick. I don't really like this chair, because it is also using a lot of material, as well as not much strength happening.

Another furniture inspiration

Finnish designer Sebastian Janson presented a new collection at the Salone Satellite in Milan this year.

HABITUS is a bar stool inspired by "studying the formation of coffee leaves", constructed form geometric shapes. With its sculptural appearance, It gives character to a space and environment, inviting the eye to glance over its anthropomorphic structure. By studying the formation of coffee leafs, Jansson was able to re-create the stool through this intricate arrangement of geometric forms, whilst maintaining its aesthetic qualities and comfort. It is constructed from lsaer cut steel, folded then welded.

Another work of his is CUMULUS modular lamp, a contemporary study of two materials. The light is deflected in six directions within a sphere, and diffuses the light in a spectacular manner, creating an optical illusion. The use of Velcro® Ultramate® as a joining mechanism, creates an extremely rigid framework as together it forms the skeletal structure for light diffusion. The aesthetic of the light has been inspired by clouds, as there is no limit to how this system can be arranged. Yet again, Cumulus is a reflection of Jansson’s geometric interpritation of the organic environment.

Full Scale 'Mock-Up'

Design Development 3

First paper trial that i did before doing the full scale mock up. i was trying to make a 'diamond like' chair, which has 16 sides at the middle and 8 sides at the top and bottom part.

Paper Try-Out and Drawings

This Chair was absolutely driving me crazy, even constructing it with paper. The parts to be joined is too small, and made it really difficult to assemble.


Second Paper trial : i tried to reduce the sides down, from 16 to 12 for the middle part, and the top and bottom part has 6sides. This one made it easier to assemble, but still it wouldn't fit into 1800x1200 cardboard. Here are the template, some paper model shots and drawings.

Finally, the full scale 'Mock Up' that i did from refining the second paper trial design. i reduce the size of the middle part, so that it can fit the xanita board that will be given for the final. The size of the seat will be 300x300mm, and the height will be approximately 470mm.

Done

This chair is not really successful yet, and when i tried to sit on it, seems like its not strong enough. Maybe because the material that i used is from a recycled cardboard box, and already had some folds. Hopefully it will be stronger in xanita. :)
