Reconnect BOX

I'm interested in ideas that help us control our phone use and actually live our lives in a better and better way. I thought of a simple idea which is a box we put our smartphones in, that has a smartly controlled lock and can have a timer that is set so that it doesn't open before the specified time has passed. This time away from our phones can then give us a chance to explore ourselves, the world, and the people around us. This is the basic idea that I have thought about and I can think of some other appropriate characteristics that can be added to this idea so that it becomes more entertaining and attractive within the limits of the possibilities and time.
