Design for Environment (DFE)
We found that the soda gun is optimized for multiple users to deliver a variety of soda drinks from the same location. In terms of functional optimizations, the soda gun could be made more ergonomic and more easily cleaned. These changes could improve the life of the gun and its ease of use. Parts could be optimized to take into account the degradable nature of the materials used, but the added cost of different materials could make environmentally friendly materials less practical to use. Further, the packaging of the gun could be optimized to reduce waste and save on transportation costs. Finally, the parts can be made easily replaceable (especially the O-rings) which would prolong the life of the system as a whole and cause less waste allowing the gun to be reused instead of thrown away. This can be done by standarizing the parts and making the gun easy to take apart with only simple tools.
