Not a mere engineer, that is a hasty generalization.

Some say Phillipe Starck is one. Not exactly. Raymond Loewy was one, as was Henry Dreyfuss. I am also an industrial designer - well, at least a derivative. The industrial designer takes into consideration a balance of the human senses, from the physical to the financial, and expresses them through mass-produced products. One can say that the industrial designer is actually a humanist, designing for the everyday person.

Most of what industrial designers do deals with the interaction between the human and the object through its design and development, through mass production techniques to marketing for the right people. In other words, the Product Life Cycle. The industrial designer is in fact a representative for humans in the development on machine-made objects. Without the industrial designer, there is no ergonomics, styling, usability, or maintenance. The engineer takes care of the design of internal mechanical components, making certain parts work like they are suppose to. The industrial designer's responsibility is mainly that of the interaction surface, whether it is ease of access in replacing a burnt motor, or specifying santoprene for a drill grip.

Please do not mistaken an industrial designer for an engineer. Both are useful in their own right, and they obviously have distinctive characteristics.
