designer's own words:"
This shelter and cart fold into a small, portable backpack. The backpack is made out of two pieces that are molded out of recycled plastic; these comprise the body and the door. The door (which is at the front of the backpack) folds open and snaps into a right angle position to create a dolly. The backpack has two straps that have an elastic core. This allows the straps to double as bungee cords. In this way, items can be strapped onto the dolly or to the front of the backpack when the door is closed. The picture shown has one strap in use that crosses the chest of the individual carrying the backpack. On the backside of the backpack there is a handle that extends upwards. The handle has hooks on either side which adds even more storage options to the unit. In the picture shown, the hooks are being used to hold bags with recyclable bottles. The handle allows the user to tip the backpack back and roll the backpack on its own two wheels. The wheels are raised so that the backpack only rolls when it is tipped back. Otherwise, the wheels stay stationary. Behind the extendable handle is a compartment which holds the shelter. The shelter is a tent made of waterproof fabric that has a spring steel wire frame and extends outward seven feet. The wire frame gives the tent structure and allows the tent to be freestanding. It does not have to be anchored down. To store the tent one simply pushes the end towards the backpack, and the tent folds itself up. One can grab the collapsed tent on both sides and stuff the tent into the compartment. The spring steel has memory so manipulating the tent like this will not destroy its structure. While creating this unit it became evident that this solution would also be useful for victims of disasters.
