We often share one umbrella with other when the rain is coming.However ,sometime we cannot guarantee both can shield the rain by the small umbrella ,which leads to someone who have to be soaked at shoulder and backside or both get involved. So that points to we usually ignore each other weather be soaked or not,therefore in order to address this problem ,we transformed the traditional umbrella and applied the reflective material on the inside of umbrella edge which easily can observe this wringing situation and to adjust the umbrella to regard friend.
