FRIDAY 7TH NOVEMBER- TUTORS FEEDBACK
From Friday we have been given feedback from our chair, even though it collapsed, however the tutors said it has a great potential to work and its well structured, they liked the whole aspect, the fact that it was versatile.. its a very stylish stool, however we need to work on our concept more it needs to have a clear understanding at what we are trying to sell our product to and where it can be used.
They didn't really say much about our stool, but as a group e then got together to see who we could improve it and we were thinking over the weekend and coming back Monday 10th November everyone had an idea of how to fix the solution and we all agreed on each others ideas and carried with our final 1:1 model.
Evaluate and review the testing process to make improvements to the strength and design of your structure where necessary.Once the initial design was agreed upon by all of the members of the team we had constructed prototypes to test out the usability and determine where the strengths and weaknesses were within the design. The first prototype that was created was at a 1:2 scale. When this model was made each member of the group had personally seated themselves upon the stool to test the strength of the slats that would support the weight of the human using it. From this we had noticed that at a small scale it was able to support all of weight evenly by distributing the direct loads across all of the slats which in turn reduced the stress and force imposed upon each individual slat. As this prototype had been successful we had decided to progress further with this concept and create it its life size scale (I.E 1:1).
Unfortunately as result of testing the full size prototype we had discovered that the shape of the slats created at the time of development had caused the external panels to ‘POP’ out of the designated positions. From this we had decided to create various designs and prototypes of slats to see which ones would be best suited for holding the external panels in place securely. Also from the full size model we had found out that as a result of cutting out the panels in against the grain of the cardboard being used the strength had become significantly weaker, which in turn had meant that the overall testing of this seat had failed due to collapsing under the weight of a full size adult. Also as a last resort we had come up with the idea of creating additional supports that would be placed within the grooves on the side of the seat where extra strength could be gained as well securing the external panels tighter into the structure.
The next step with testing was to create the final life size model that would be used to demonstrate the quality and purpose of the product that we had designed. Once we had constructed it we had each tested it and had no issues from strength and comfort was nicely achieved through the level surface. However like any product in different conditions different performance values are obtained and results would have to wait till public demonstration.

STARTING THE 1:1 CHAIR
Here we have changed our slats from a round curved edge to a squared cut edge, as from our review our chair collapsed because of it slats and grain from he cardboard running the wrong way. so we have tested our new idea not he slats using a squared/ straight cut joint for the slats to hold in place with the outer part of the stool.
|
here as you can see the slats don't properly join together and they instantly pop out of place, as you see above they popped out and wasn't stable enough for the user to sit on it.
|
So this was a completely different slat using squared/straight edged joints for the join to take place, first we have tried it out on our own cardboard instead of starting straight away, this was we could see what would work and what didn't.
|
USE OF CAD FOR FINAL- 1st idea and 2nd idea
This was our initial idea to do , however from our 1:! prototype we saw some errors occurring therefore from that we knew it wouldn't work and we saw that it wasn't secure to hold a human's weight on top of this, what we also noticed is that the top isn't comfortable for to sit on as it would feel our of place on the stool.
|
so then we went onto this idea of making it a flat top which worked so much better as it was more of a shape of a stool, however last minute we had noticed that our stool had a bend within the slats and we had to make it more secure for the client, so we have added an extra slat on the sides to hold its weight and not let all the weight go on the slats.
|
Here are some CAD drawings in which we have done based on our stool, showing the different elevations on the stool and also ones with the correct measurements on, this gave us an idea on our sketches to from where to work from and where to start first with our stool.
EXPLOSION ISO
Creating an Explosion ISO helps people see what parts go where within our chair, this shows a great understanding to the users of the stool to know what goes where on the chair as it will be easier to put together for them, we might even include this in our instructors manual for the audience to look at how the final product is suppose to be like.
PARTS/COMPONENTS LIST
Our chair in real life context
So here we have mocked up our stool without an environment to show how it can be used, using AUTO-CAD, we have set out a scene for the users to see how it can be used and where it can be used. setting the scene within a living room but it could be used elsewhere swell, but within these scenes it shows it could be used as a :-
Footstool
Side table
Stool
Using colour and black and white to show it, we thought using both colour and black and white to see which one is more effective for the A1 panel, and looking at the black and white panel it shows it more effective and sharper than the coloured one, but the coloured one also didn't seem to fit well on our panel.

Also setting the scene in real life swell we have shown our own independent photographs to show that it works as the 3 options above, we have tested it over and over again and it works really well, our next step is to see if we can take it elsewhere like to a coffee shop to be used there.
So it been used within a different environment instead of your house, we have taken our stool to a coffee shop local to our university and its been used there as a footrest, side table, and stool. it was great because the coffee shop had small table's and the sofa's were quiet high up form the tables whereas our stool is at the right height for someone to sit around he table talking to there friend while having a cup of coffee.
A1 panel layout ideas
Here are 3 ideas in which we came up together, we wanted to create a timeline of our work using arrows and the whole page, but we found it difficult to arrange our text either it was too big or too small or the space would be less to fit the text there.
we wanted a nice and clear panel which shows our product straight away and has the attention on it as soon as you look at it. we have kept it legible and simple so the page isn't to crowded with text or images it has a interesting grid system layout.
Using a Helvetica Light and regular typeface at 14pt was an ideal size to use as when we went to print it out it was legible to a certain distance. what we also looked out for is the structure of the panel, we have arranged everything equally and scaled appropriately.

EVALUATION
The journey in making our chair has been one of a journey of overcoming problems and trying to find solutions to conquer them. The initial problem we had was in coming up with designs, in which we spent a day just investigating precedents and drawing out ideas that could possibly work. However, once we narrowed it down to one design, we had to produce a 1:2 prototype chair. We didn’t find a lot wrong with the 1:2 chair as it appeared strong enough, however when we constructed it in 1:1 there were unfortunately a lot at fault with it. The exterior kept on popping out of the slots, both at the top and sometimes at the side (the ridges). Also, the seat was not strong enough to hold an individual, as soon as one of the group members sat on the stool, it immediately collapsed. We deduced as a group that we did not cut out the pieces in favor of the direction of the grain. Therefore, the structure was inevitably weak. To strengthen the cardboard stool, the material was cut in the direction opposing the grain. The slots were changed to a slim straight line rather than a curved joint, to stop the exterior card slipping out. As well as this, extra slats of card were also added in between the side slots, to make the exterior card to tightly fit in. Although it was hard work, we enjoyed the process and the thrill of having a great end product that satisfies the brief. I believe we effectively worked well as a team, distributing the work evenly and in a way that worked with each other’s strengths. If we had more time, we had the idea of painting the chair with a mixture of colors inspired by ‘transformers’. Nevertheless, we are pleased with the final outcome and the evolution of ‘Mi’ stool.
