FUGU is a suitcase that can quadruple its storage capacity. Customers can choose between a carry-on suitcase that complies with airline standards and a full size check-in suitcase. The size change is facilitated by connecting FUGU to a standard electrical outlet, causing an internal mechanism to inflate the lateral walls. The advantage of the structure chosen is that it is an extremely durable construct. The ergonomic aspects result in different options for suitcase use, such as: check-in mode, carry-on mode, trolley mode and use as a portable work station. The aforementioned features create a new user experience and new user scenarios.
