CAD/CAM, The Drill Project: Product Design Brief

After evaluating the new ‘Drill’ brief, I decided to design a drill for ‘Design Students’. My decision making behind choosing this target market was due to the fact that I can relate to this group directly.


Your brief is to design a new 18v cordless drill to be manufactured by SPC. The new design must be styled to appeal to one of the following target markets: design students, DIY hobbyists, enthusiast hobbyists (prosumers) or professional trades people. Your new design may be aligned with an existing brand or you may create your own.

Your design must:

  • be appropriately styled (i.e. aesthetically pleasing and desirable)
  • be functionally credible
  • be ethically and socially responsible
  • consider the 4R’s
  • be developed using the CAD-CAMM product development process.

In addition, in order to reduce development costs, you should re-use the existing trigger switch, motor, chuck and gearbox. . All other components must be designed to appeal to the chosen target market. This includes a new heavy duty 18v battery pack which must accommodate 10 standard lithium ion 18650 rechargeable cells.


‘The Sustainable Products Company’ (SPC) is a [fictional] company based in Mid Wales. The company believes strongly in socially responsible design and specialises in the manufacture of ethical and sustainable consumer products that are marketed under a wide range of brand names. Their factory is powered by renewable sources (including solar collectors, a wind farm and a hydro-electric facility) and has the following manufacturing facilitates:

  •  Injection Moulding of recycled polymers
  • Sand Casting & Die Casting of recycled Aluminium
  • CNC Punch Pressing of sheet Aluminium and Steel (plus general sheet metal fabrication)
  • CNC Turning of Aluminium and Steel
  • CNC Milling of Aluminium and Steel
  • CNC Routing of Wood (plus general wood fabrication)

The company’s market USP is the redesign and manufacture of consumer products to make them as sustainable as possible. This typically involves the application of the “4R’s”.

1) Reduce the quantity of materials used and source from renewable sources wherever possible.

2) Re-use materials or components wherever possible.

3) Recycle all scrap materials that cannot be re-used.

4) Repair-ability. Increase the useful life of the product using Design for Repair (DfR)
