According to the abstract released by the Intellectual Property India: "The present invention relates to a Mechanical Smart Projector and a method for projecting phone screens without using any power. The system uses a 45 mirror and convex lenses (110) to project the phone's display clearly onto a wall or surface. It includes manual focus and zoom controls (130) with rotating knobs to adjust lens distance. The projector has external press-buttons (140) inside the box that let the user control the phone's screen without touching it, for functions like play, pause, and skip. A scroll wheel or slider (150) moves a soft stylus on the phone screen for easy slide navigation. Audio output (160) connects via a wired port to a speaker for sound. An adjustable phone tray (170) with a slider helps align the phone perfectly with the lenses. The projector body is foldable (180) with hinged panels for easy carrying. Manual keystone correction (190) uses small knobs to fix image distortion by tilting the mirror or lenses. There is also a slot for attaching an emergency flashlight (200) to help in low light. The method involves setting up these components manually to project images and control the phone without power, making it an eco-friendly, portable projector for many uses."
