Software Design Puzzle #5 - Ice Cream, Ice Cream, Ice Cream

Uncle John is very tired working for a software company. It is his childhood dream to be a entrepreneur and so he resigned his job and started a ice cream business. His business idea is very simple. Like coffees, teas, milkshakes, he wants to do ice cream vending machines and sell ice creams along with ice vending machine. Being a Java developer, he wants to develop a highly flexible ice cream vending machines (and eventually patent it). He wants to give few varieties of ice creams - cone, cup and stick and so many flavors.

The question here is, how will you design the ice cream vending machine (time being forget the fact how various ice creams base/flavors are mixed and ice cream is made which by itself is a separate design problem to solve).

How will you design the vending machine?
