Milk Tea- Delight and Function Not Always Found in the Same Cup
This stout cup of Milk Tea is very popular for its kiddish feel and the store's hipster/vintage-classroom ambience brings in lines of customers.
I think this is a perfect example of when design is successfully used to increase user joy while in the process actually forfeiting function. The cup will obviously not fit into any cup-holder, and so function and usability is somewhat sacrificed. But the trade off is that now the large cup has now become iconic, really setting itself apart from other car-friendly cups.
It also forces people to drink their large cups at the store, which is just a great for their business as the store always looks happening. It always inspires me when such seemly small design ideas really can have such a strong influence on product profit.
