Please imagine/invent a product, new and nonexistent. It does not need to be feasible, logical, or obey the first/second or even third law of thermodynamics. describe that product, focus on its appearance, why it is unique, and who will use it for what.
Pay special attention to using the writing process (What is this, who is it for, why is this different, when is it available/is it used, where can I use it), to asking yourself a lot of questions that an independent observer may ask, and to focusing not just on tangible aspects such as color size and shape but also to the intangibles such as benefit, who will use it, and why it is unique. Use analogies and a lots of adjectives.
