How to do a great design and construct a good prototype.
1. Write a BRIEF where you identify and describe the problem to be solved by your product.
2. Do some RESEARCH.
- intended market: age group, gender, culture, values, interests, life styles.
- functions of the design: structural, mechanical, electrical, maintenance.
- desirable appearance: shape, form, surface texture, finish and colour.
- suitable materials: strength, hardness, toughness, density, thermal conductivity, durability...
- construction methods: cutting and shaping, fabrication (assemply of parts with glue, screws, solder), moulding, casting.
- social & environmental effects: health & safety factors, noise, smell, aesthetic qualities, pollution.
3. Write a PRODUCT SPECIFICATION.
4. Think of possible solutions. Be creative. Draw sketches and write notes about each possible product.
5. Choose the best solution. Consider strengths & weaknesses of each design, as well as facilities, budget, materials and skills at your disposal.
6. Prepare your working drawings. Neat, clear and easy to understand by the members of your team or anyone involved.
7. Realisation. A good planning is essential for successful project work. Timetable, material list, details of the construction work and progress, problems, modifications.
8. Final tests and evaluation, to show where we have succeeded and where we have failed to satisfy the specification. It is important to be critical with our own work and mention how we could improve our original design.
