How do you analyze and understand the design logic of different products and features?

There're cool products and features coming out everyday, how do you analyze and understand the product design logic behind them? My friends and I tried to do this by categorizing products and features we've seen on this mapping. https://www.fabrie.com/workspace/63aea9a4c238913275207a8a The interesting part here, though, is the blank spaces on the mapping. We think that they represent products that have not been made, thus the opportunity! We didn't finish the entire thing. After all, we can't know everything. You can add interesting products and features you've seen onto the mapping, and create your next product/feature in this mapping We've called it "the Product Design Sandbox canvas" Feel free to join and collaborate!
