FINAL PROTOTYPE

The following pictures and images are of my final prototype which will be submitted on Wednesday 9 June at 9:30am in the Uni Gallery. I decided on this design for a number of reasons but mainly for it's suitability for it's use and as an accurate response to the brief.

THE MAIN FEATURES OF THE DESING:

1. Is portable and easy to carry weighing under 4kg
2. Does not involve fixings, glues or welding
3. Is extremely easy to self assemble
4. Demonstrates an economic use of material
5. Will be economic and efficient to produce
6. May be flat packed for storage and or postage
7. Is easy to disassemble for end of life recycling
8. Is made from sustainable materials
9. Does not include harmful paints or finishes

Hope you enjoy it!

HALF SCALE MODEL

These photos are of the half scale model built to the DWX files presented in the previous post. A few changes have been made to this design for the final prototype which can be seen in the next post.

DWX PLANS

The image below shows the .dwx plan that will be used to cut the plywood into shape.

FINAL CONCEPT

Based on the analysis of the two options I have decided to continue with concept 2. I will further develop this concept into the final design.

FINAL CONCEPTS

To further develop the two concepts posted earlier I have created 1:2 scale models of each to greater investigate the method of construction and material synergy.

Does each concept meet the requirements of the brief?

1. Must be portable and easy to cary
2. Must be able to seat 1 person of up to 150kg
3. Must be easy to self assemble
4. Must demonstrate economic use of materials
5. Must be economic to produce
6. Must be easy to disassemble and recycle

CONCEPT IDEAS

ESQUISSE FOUR - MATERIAL SYNERGY

Esquisse Four asks us to consider carefully the forces placed on furniture pieces and the materials used to create them. For our final outcome, 4mm ply wood and 5mm steel rod will be used to create a cafe chair. The two examples presented below combine learned outcomes from previous esquisses in an attempt to create pieces that are balanced, sturdy and functional. Using only Bolsa wood and wire the two examples below will both be considered for my final project.


EXAMPLE ONE
This piece follows the previous study with strips of Bolsa wood being threaded together and pinned with the steel rod. This creates an extremely strong sturdy outcome however the amount of Bolsa required to complete this piece may translate to be more ply wood than we are supplied with. It also may, as a result of the large amount of material, be very heavy to move and cost prohibitive.
A solution to this problem may involve a greater study of the individual members used to create this piece and the removal of some such members in a way that allows the chair to remain sturdy and strong but also improves its function and usability.






EXAMPLE TWO
This piece follows on from esquisse two where a stool was created by using four pieces of equal sized Bolsa and two pins. Adding one further piece of Bolsa and a third pin allowed for the stool to be transformed into a chair. The simple construction and lack of fixings and glues makes this a very viable option. The ply wood being 4mm thick would require at least two thicknesses being stuck together, however I still believe this would provide a much lighter and easy to use result.





Further investigation into these two options will involve detailed pattern making and 3D studies to determine which of the two options, or what combination of each of their elements can be utilised to achieve the most desirable result.
