Concept Refinement
Once I had selected one concept out of the few that I was working on, I approached concept refinement stage by making a series of 1:3 scale models.
Once a mock-up was completed, I then analysed each individual model to see where it's faults and weaknesses were.
I then improved the structure and layout and implemented the changes in the next model.
This process allows my design to evolve and improve rapidly.
The next series of images show how my designs have evolved through more than 10 scale models.
Model 01

This was a basic 6-sided unit inspired from an origami form.
Model 02

I changed the dimensions to make it more stool-like and less cube-like.
Model 02a

I tried increasing the height by double, but this caused a drastic change in the form that was unexpected.
Model 03

I worked with inverting some of the corners to acheive different contours.
Model 04

After changing the height and changing some angles, this model was beginning to show signs of a more appropriate proportion.
Model 05

In this model, I was working with tapering the base, however, it became more unstable.
Model 06

In this model, I experimented with creating some inward angle to try and change the direction of the load stress from vertical to horizontal.
Model 07

I curved the base of this model to experiment the possibility of a slight 'rocking feature'.
It didn't work.
Model 08

In Model 08 i began experimenting with various locking systems and how an internal skeleton or cross section could further strengthen my stool design.
Model 09

In model 09 I was still working on locking systems.
Once a mock-up was completed, I then analysed each individual model to see where it's faults and weaknesses were.
I then improved the structure and layout and implemented the changes in the next model.

Step 1: Layout.

From L to R: tongue and groove locking system, unknown joint, mitre joint, curve joint.
Step 2: Unknown joint.

Although the thickness of the X-Board is 10mm, the material folds in on itself.
Therefore the width of the cut should only be 9mm wide.
Step 3: Mitre edge.

Similarly, instead of a 20mm (10mm x 2) width cut, a 18mm (9mm x 2) cut would be more accurate.
This is because of the 1mm 'skin' of the X-Board.
The challenging part of this step is getting a crisp and sharp edge.
This can be done by scoring the inside of the X-Board before folding.
Step 4: Curved edge.

To acheive a smooth radius, the X-Board has to be bent slowly and carefully.
Scoring the X-Board would help acheive this, as well as controlled compression/crushing of the 'honeycomb' stuff inside the X-Board (after the skin has been peeled off).
Step 5: Completed cube.

Dimensions: 6mm x 6mm x 6mm
