Hi, I am a Computer Aided Product Design Student at the University of Northumbria, and for my final year project I have decided to come up with a concept for people who carry their grocery shopping home by hand. This is a definite problem and one without a real solution, other than paying for a taxi to take you home (extra costs and waiting around). My idea is to design a wheeled storage device that collapses into either a backpack or a shoulder strap bag for when the container is empty. This will ensure that when you are travelling to the supermarket you won't have to drag an empty storage device with you (including around the shop) and then put it into its storage device function when you are at the till. I would love to know peopleâ€™s opinions on this type of product and whether they'd use it or not. Also what other purposes could it be used for. Thanks all!
