18. project development (May 28, 2014)
Make a prototype using ready-made parts
I made a first prototype from commercially available ready-made
parts by bricolage methods, in order to verify the size of the
components. Firstly, I collected the components needed for the
prototype in the MUJI,
a Japanese retail store. MUJI is one of the company which has an
understanding for the fab lab movement and held an exhibition
related to open furniture design in 2012. You can download the
drawing sheets from this page (written in Japanese).
In this bricolage, the components I collected are shown below.
10 items or less.
List (from left to right)
- Tundish (Funnel)
- Water purification pot
- Compression bag
- Gusset case
- Luggage cart
Then I stacked the modular components for water utilization on
the luggage cart. The total weight is approximately 3 kg.

Note: This prototype does not include the electronic device (e.g.
water temperature meter), shoulder strap, and connecting
I verified the size and each function of these components, and
then 3D modeled the second prototype.

I'm making the second prototype with local common resources
using the way obtained by literature and field research on folk
tools and crafts in Asian countries.
