differences in Industrial design and product design?

Could someone please point out the difference between the roles of industrial design and product design as i have no grasp of the difference… My curreny opinion is that the Id guys are middle btwn the engineers and the Product designers. The the pd guys go wild and whacky… the engineers make it happen and the id guys could do both or either

Best Regards,

In short, none. Just that some people dont know what ID is, so PD came along.
