How does your final design meet each of the four specification points you wrote earlier? Use sketches and notes to answer this question.
 

1. The chair will be in the same style as the Maclaren B01 child’s push chair / buggy.

I selected tube for my folding chair, as it is the same style as the B01. The mixture of canvas and tube also relates to the B01. The chair folds in a similar way as the B01.


 
 
 

2. Lightweight tubular aluminium (round section) will be used in the manufacture of the chair.

The round section aluminium tube I have selected for my design, is ideal as it is lightweight and yet strong. The aluminium is easy to cut and shape compared to steel, with the added bonus that it will not ‘rust’.

 

3. The chair will fold, so that it can be carried and stored easily. It will lock in position when opened, so that it is safe.

My chair can be folded with ease, as seen in the developed design. It is in two parts and is kept in it own canvas bag. This keeps the two parts together, ready for use next time it is needed. The folding mechanism locks in position, when the chair is open and ready for use.

 
 
 

4. The chair will be ergonomically designed. It will be comfortable when seated and comfortable to pick up, move and fold away.

The chair has been design with ergonomics in mind. The canvas seat is comfortable and the vertical back rest ensures that the person sat on the chair, is sat in the correct posture. The height of the seat has been calculated using anthropometric data, working out the average seating distance.

 
 
 
5. The joints will allow for movement (folding) and they will be strong, in order to take the weight of an adult.

The main linkage joints allows the necessary folding and are very strong due to using rivets. The moving joints do not comprise the strength of the chair. The two way push fit joint, has allen key adjustment that locks the joint and tube together. The chair is strong and stable and will have a long life cycle. It can be completed recycled at the end of its lifetime.
