It is a big responsability for designers to bring a new product on the market. Many peolpe are involved in the objects live; from the production until the comsumer and the environement. This work is and will always be a team work. A goog designer can´t possibly know everything so he will have to look for all the information he needs, to make the best synthesis, and have a little bit of genius.
It is a long way to create an industrial object. There is no secret but a lot of thing to know. I like to participate in the developpement of industrial products because I know I will never stop to lurn things which, sooner or later, can be usefull for the next product to design.
Have a look at the design process I use to create an object.
