There is something both daunting and delightful about tackling a traditional object design that has already stood the test of time. On the one hand, they are nearly impossible to improve. On the other, if you can indeed add something, it provides a whole new perspective on an object everyone thought set in stone.
Consider the Red Dot design award-winning Bevel Cup by Gao Fenglin & Zhou Buy, designed to stay cleaner in storage than mugs sitting right-side-up or upside-down. It also makes for easier drainage when letting them dry either on a shelf or a rack.
The “Bevel Cup has an angled handle (at 40°angle to horizontal plane) that allows it to stand at an angle, upside down, but resting only on the handle itself. This keeps dust out and germs off the rim. This storage position is also a good indicator that the cup is ready to be used rather than in need of a wash after a previous use.”
