The basis of a design project which will be completed. You should therefore think carefully about which of the following Case Studies you choose, based on your knowledge of the theory and practice of the product chosen.

For ONE of the case studies given on the next page, complete the following.

1. Derive at least four concept designs to satisfy the given specification. Use short written descriptions and simple sketches to illustrate your ideas. Show evidence of the use of the following techniques:

• brainstorming

• synectics

• morphological chart.

2. Use the weighted objective method to select your best solution from any four of the concept designs.

3. What other information would be required to be able to write a more complete Product Design Specification? (Use an objective tree to clarify and expand upon the vague brief given.)

Case Studies

Choose ONE of the following.

(a) As a keen, but economically challenged, cyclist you need a means of carrying two bicycles whilst travelling between destinations on a touring holiday in your small car which has a tow bar fitted.

OR

(b) It has been found that to improve product quality, a process stream leaving a storage vessel on a chemical plant now needs to be cooled from a temperature of 100ºC to a temperature of 50ºC before entering the reactor. The ambient air temperature averages 15ºC with a high of 25ºC. A water supply at 40ºC is available.

OR

(c) An analogue/digital circuit trainer is required for students to construct circuits. The design requires:

• the ability to build circuits

• associated power supply

• a suitable waveform generator

• a means of measuring current, voltage and resistance.
