My diploma thesis was a gender study dedicated to a car personalisation of men. Project was focused on a flexible storage unit suited for male needs. The product reacts on two different scenarios: i) storage for small male bag, ii) storage for bigger A4 format bag. The point was to create a container that can be adjusted according to a type of bag a man carries during a day. By using simple rotational knot it can quickly change its volume based on a situation. The storage is situated between the front seats and it also works as a driver´s armrest.
