Where is the cut-off point between Product Design Engineering and Mechanical Design Engineering or are they the same thing? Is product design the process of designing an empty shell of a product which is aesthetically pleasing and a proposed with a list of innovative design features and functions. If so I where is the â€˜Engineeringâ€™ aspect. Does a Mechanical Design Engineer take the design and does everything necessary to make the product work? If so where is the â€˜Designâ€™ aspect? I have looked at Product Design and Mechanical Design courses at a university to understand it better and the Product Design course pre-requisite is an Art A-Level. My Mechanical Engineering Degree required me to have a Maths or Physics A-Level and the course was very analytical.
