Development

1. This is the time to select from your initial ideas the best of them and bring these together into a single design that you will make. They might be the best because:

1. They best meet your requirements
2. Are most liked
3. Look the best
4. Provide a very good solution to the problem
5. ou will be able to make them to a good quality standard.

2. Good design is always a compromise, now you have to turn your ideas into a practical project.

3. Everything is made up of many smaller parts, you have to design EVERY one of those parts and show how to make them and how they fit together.

4. Take each part starting at the top or the bottom and work through the product part by part: E.G The base box to contain the battery and LED’s. Consists of a base and 4 sides and a top. They all need drawing. The batteries and LED’s are fitted in somehow design how. Generally when you buy things the parts inside don’t rattle about – neither should yours.

5. So you will need to decide exactly how the project will be constructed. This will mean considering each part of the project and how they fit together.

6. You will need to decide on sizes for each part. The Materials needed, how that part will be made.

Modelling

1. This is often the time to make some models to experiment with how things work or how big they need to be. Any modelling you do should be photographed and included in this section with note explaining what you learned from it.

2. The final design will be drawn as working drawings. Usually 3 orthographic views of the whole object and of each part so that the correct dimensions can be marked on them. This is a good place to use 2D design CAD.

3. Decide on the materials required.

4. Decide on the construction techniques you will use

5. Make a table showing all materials, what they are for and how much you will need. A costing can be done now as well.
