This document outlines three problem statements and proposed solutions: 1. A safety device for girls in the form of jewelry that can send an emergency call and message with the press of a button. 2. A handleless umbrella enclosed in a portable container for easier carrying that reduces hand strain compared to traditional umbrellas. 3. A mobile app that allows audio-only playback of YouTube videos in the background so other apps can be accessed simultaneously, like viewing photos during a speech.
