First of all, I think paper cups should be creatively designed. It may be common, but under the premise of meeting the function of paper cups, there must be some creativity, such as cutting a curve that conforms to the mouth shape at the mouth of drinking water to make people drink more comfortable. This kind of paper cup is common, but it must be unusual, because it is integrated into your mind.

Another way of thinking is that the paper cup no longer performs its original function, but becomes a work of art or has other functions. For example, connecting a paper cup with a lampshade, putting a light bulb in the paper cup and painting decorations on the outside of the paper cup will become a very interesting little lamp. Or make paper cups into grotesque pen containers or use them as speakers, all of which are very good.
