So an industrial design product is more like the houses you see on the "Grand Designs" TV show. In a way it's like forking a software project: the more you deviate from what's done before, the more 'pain' you'll be in. What's done before can be re-done by any competent builder. But beyond that, you'll need expertise in different fields, to fit parts of a design together in new ways. No expertise -> project will fail, or be extremely 'painful' (like: costly, time-consuming, many iterations, result isn't what you wanted, etc). Enough expertise -> steps in new territory might be uncomfortable or include some mistakes, but overall you'd know where you're at, where you're going & have realistic expectations. So yeah - nothing wrong with getting some expert help when entering new territory.
