Step 1A : Tuesday 28th October 2014
Anthropometric study
We were asked to collect and record the dimensional data from each member of our group necessary to our design product, which was used for our design to cater for a variety of seating types. This collection of data could then be utilised to produce a chair at a large scale, using cardboard. We then also looked at gender, age and ethnicity. From there, we then took all the measurements we had collected to work out an average to help us, we then had to consider short and tall people within our group and therefore how the chair could vary in height.

These are all the measurements taken, which were asked of us in the brief. However, from this data we were able to extract the most important information that we needed for our product. We also needed to be aware of the extreme ends of the spectrum, looking at the smallest individual to the tallest one.

These are CAD images of the measurements taken of the tallest figure to the smallest. CAD was used as a interesting way to display each measurement in a simple way that we could understand what the measurement was of. It could also allow easy comparison between the two figures.
Step 1B: Chair Challenge Tuesday 28th October 2014
For the Tuesday studio session we were asked to bring with you a bag full of waste card material each. The bag is to be the same size as a plastic bag from the supermarket and must be filled with card of various types....thin, thick, cereal boxes, toilet roll tubes if necessary. This is one bag per student
will also be required to bring...
Measuring tapes
Rulers
Sketching pencils and equipment
Camera or camera phones
Using our waste and found materials we had a single afternoon project in which involved the construciton of a seat from a secondary sourced materials. this could be materials that have been recycled, donated, found, taken from scrap. No materials may be brought. This seat will explore structures and as a group we learnt through testing the difference between various materials in terms of their strength.

Using our waste and found materials we had a single afternoon project in which involved the construciton of a seat from a secondary sourced materials. this could be materials that have been recycled, donated, found, taken from scrap. No materials may be brought. This seat will explore structures and as a group we learnt through testing the difference between various materials in terms of their strength.
So here we have pictures of our work. Using our waste materials was challenging, we had drawn some sketches to share amongst our group to see what designs we could come up with. During this process we all worked as a team and had input in everything. Moreover, we made the use of the workshop to cut down our cardboard to make it using the appropriate tool provided, then we filed it down to make it all one size and to have straight edges in order to stand up.. One error which we all came across as a team is that we made the base of the stool upside down, as the shoe box was opening up we had to think of another idea to make this not happen. However, we overcame this by adding more card underneath, which intersected with the cylinder cardboard, which unable the bottom not to open. Overall, when tested the seat we saw that it was strong enough to support the weight of an individual.
Step 2: Tuesday 28th October 2014
Completing that activity we were then asked in our groups to identify the activity to be performed in our chair and the potential client/users who would need or buy this stool, also looking at the initial design, defining the particular requirements of the seat -aesthetic and functional through a design statement. also identifying the basic ergonomic concept involved in being seated on our chair, so looking a show it can improve with comfortability and structure to help a human sit comfortably. We then made an evaluation against our product to our waste materials in terms of their strength and material properties.
- Design Statement
The purpose of this project is to design the ‘ultimate chair’ that expresses its own qualities through structural and material principles. The chair can for any purpose but only be created from a cardboard structure. The approach to this design is making sure that the chair solves the issue of posture. The reason for this is posture holds the key to being comfortable and without good posture injuries and issues can occur across the human body.
Major goals of the design include:
· Incorporate anthropometric requirements
· Incorporate aesthetic principles into the seat
· Make sure that its functional and suitable for its purpose
· Create prototypes of designs to ensued functionality.
The primary constraints on the design are:
· The structure of the chair must be constructed entirely from Cardboard
· The structure of the chair must not contain any adhesives to support the structure
The project team consists of:
Jordan Allen
Jasmin Bhambra
Tom Bevan
Chidochashe Vanessa Mawoneke
- Identify Activity for Chair & Potential Users
The potential users for the stool is people of all ages. The reason for this is because it opens up more potential designs and offers a better standard of product those who would need it. With it been targeted for people of all age’s means that more consideration has to be taken when trying to accommodate different bodily needs.
Basic Ergonomic Design Principles Involved In Being Seated When designing any seating arrangements there are some basic ergonomic design principles that should be considered in order for the design concept to be successful. Some of the basic principles are:
· Lumbar Support
· Armrest Support
· Seat Pan Depth
· Seat Recline

Evaluate Your Waste Materials
For the waste materials that we had to use cardboard. The cardboard used has many properties in both its strength and generic. Cardboard can have / will often have multiple layers of fluting which is sandwiched between layers of cardboard pieces. This method that is used to create the cardboard is a good one as it enables the final structure to hold a greater force of strength in both compressive and tensile areas. And because this method increases the strength throughout the whole structure it enables further potential by creating extra layers to reinforce the material. Once all the layers have been created and merged together the material itself becomes very durable. This is because the fibres that cardboard possesses are strong and robust which in turn makes the material puncture resistant. Some properties of cardboard are not all positive as one its main negative properties is that it’s both prone to weakening in presence of liquids and is of a flammable nature. Because the material has flammable properties it is unable to be used in certain applications of products as it could pose a possible risk health and safety. Also because it is prone to weakening in presence of liquids it can’t be used in situations where liquids are to be used.

Step 3 : Tuesday 28th-Friday 31st October 2014
During our own time out of university we all got together on Wednesday 29th October 2014 to come together as a group to see what ideas we all come up with and to finalise one for Fridays lesson. In a group we developed the form, developing a unique proposal, through sketches and sketch models using various scales, this helped us to think of more ideas as we all sketches ideas down, the more ideas we have the best we can come together to take from one another. However we had to think about the structural properties of the material, as we are only allowed certain amount of cardboard we need to think carefully as a team about the size and how much we will be using. Through our sketches we have been inspired by some ideas when everyone presented there chair on Tuesday 28th October, as we intrigued about how good everyone chairs was and how strong they were.
MODELLING OUT OF CARDBOARD
Here we were experimenting with recycling materials to create a chair of scale of 1:4 to get an idea of different types of joints and the properties of the material. Building these experimental chairs was really helpful. We were able to reflect back by evaluating the use of joints (interlocking joints) and how the joints of the card effected the strength of the chair through manipulation. We could then use these evaluations to help design our actual final product.
Here are a set if images of us using our school workshop to refine the edges of every piece of our chair 1:4 model. We used the facilities of our school for our advantage, which was the quicker and easier approach of using the machine then manually sanding it with sand paper.
