My product is a circle that will go over the home button that will stop the user from pressing the home button while driving. When plotting out all of my dimensions, l realized that this would have to be extremely precise if l want it to actually work. After many ideas and days of looking through apple patents and thinking about how l can make this fully functional, l finally came up with a design

Yes l understand that it just looks like a plastic circle. But this plastic circle took days to get the dimensions and even longer to figure out how l can get it to stay over the home button. At this moment l realized that my simple piece of plastic will take much longer than l thought.
