The objective of the design was to increase the mobility of the vending shop and reducing the work load of vender.Instead of making the product bigger, the design focuses on having multiple uses for the components which ultimately reduce the number of components in the design.When mobile , the large styrofoam containers  is used for storage but when the product becomes stationary , the containers can be inverted and used as chairs. The sliding lid which covers the containers can be pulled out to serve as a mini-table. 

A dynamo is attached to the wheel converts the mechanical

energy of the wheel into electricity. The stored electricity can

be used for charging mobiles and operating lights/speakers.
