Nice thinking. A few things you might want to think deeper before you get started:
First, are these products already in the market? My impression is that all of them are already in the market.
Second, maybe what you have proposed are variations of existing products, and a big point you mentioned was to reduce cost and improve quality. But how do you reduce cost and how do you improve quality better than all the others? These two aspects are the goals of all manufacturers.
Your key intention of easing poeple's life is a very good start, imho.
