Nowadays, we live in an era of rapidly changing trend of fashion. We expect to keep consumers from overspending and being awkward to storage and maintenance of hats. Therefore, “convenience” and “economy” are our main theme of this innovation. The principles of this innovation are to save storage space, reduce spending, and have storage easier. The Versatile Hat comprises the crown of the hat and at least one brim. There are three types of attaching parts at the bottom of the crown, namely buttons, Velcro, and studs; additionally, corresponding attaching parts are at the bottom of the brim so as to incorporate the brim into the crown. This ingenious design can create multi-pattern hats simply by attaching the same crown into different brims; these replaceable brims make the Versatile Hat a snap-on product. That is to say, one Versatile Hat provides many different patterns of hat to match various clothing and different occasions. For storage space, users need only one small space to lie just one crown of the hat rather than several crowns. This creative design can meet modern people’s demand perfectly by providing multi-pattern hats without overspending and also reducing storage space.Keywords: Versatile Hats, Patent, Innovation.
