Invention, intellectual property, and income

I think my system could be good in a shop of furniture.
So the plan is to make a nice video explaining what it is and what could it be, create a website that explain the idea and wait and see ...
The fact is that I can't push the project to reality (wich means for me that thousands of people will use it) all by myself and my moneybox, so I will need to work with other people, and get some money to help the development. It could be done by running for a business incubator, but that will wait for me to get my master's degree in 2017 !
I will also send an "enveloppe soleau" with all my works. It is something related to the french institute of intellectual property, and it's just something to say "I did that at that time". So anyone could still use your ideas but no ones could forbid you to use them.

The exact use of an Enveloppe Soleau is to :
-Proove that you create something
-Give you the copyright ("droit d'auteur" in french, wich is atribute to you as soon as you can proove you create something).
-Give a date on what you invent.
