Hey! Here is the prototype that we have built for the challenge.
The materials that we have used to build it are cardboard for the structures, paper cylinders for the joints, a plastic bag to simulate the bag of the shopping cart, soda cans for the wheels and tape to join the different parts.
Regarding the structure, there are two parts. We can see the main structure that is composed of four legs with cans attached to the endings that are the wheels and the handle from which the user holds the cart. On the other hand, there is the structure that allows the bag to move upwards and downwards that is made up of X-like structures and different axis that allow the movement. The bag can be removed from the structure so that it can be easily cleaned.
The main struture can be folded by bringing the legs upwards to the place where the handle is. The structure of the bag can also be folded with the bag inside so that it takes up little space to store it.
In the final assembly we can see how the bag and the main structure fit together to conform the whole shopping cart. The bag moves upwards thanks to the structure built for it. It is also shown the shopping cart next to a person, so we can have an idea of the cart’s dimensions.
We are very thankful to Design Team 3 for providing us with such useful and illustrative information in order to build the shopping cart. We very much like the design and how it would adapt to elderly people. To give some feedback, we feel that it would be nice to be able to adjust the handle’s height, and to add to the bag a lid or something similar so that the food that is stored inside the cart doesn’t get wet.
We are very glad to have participated in this challenge and we really hope that you like our prototype!
