1. The document proposes an invention of an "invisible airumb" umbrella that uses air instead of fabric for its canopy. It would blow ambient air through a trunk to create an air dome over the user's head for protection from rain without getting floors wet or causing collisions between umbrellas. 2. The technology would use a digital fan motor to inhale air and expel it uniformly over the user in a canopy shape. Users could adjust the air flow to compensate for rain intensity. The trunk would be retractable for easy carrying. 3. The product could target all customers and be marketed and sold through various domestic channels like shopping complexes, supermarkets, and online to reach a large global market. Future
