Industrial Design covers it.
Unless you want to be a design engineer - which is what I am in essence in part of my job. The difference is that ID is more about form, and DE is more about function.
I mean, if you were to try and separate both categories, both are about design but the Industrial Designer is more about Design & Form, while the Design Engineer is more about Function + Form because s/he understands more about the nuts & bolts of the processes involved. A DE with less talent however understands less about form than an ID but is probably able to create a better product from a functional sense.
