FINAL IDEA

We chose vending machine as our final idea, because we think that this solution offer more remedies to solve the problem of smelly people in train. A vending machine can sell many products, which give passengers more choices.

                         Vending machine inside train                        

                                                             Vending machine at the waiting platform

Specifically, we decide to set up the machines both inside the train and at the waiting platform as well. The vending machines at the waiting platform will help people to purchase items that they need to solve the problem of smell before boarding. It also gives people opportunities to prepare  before boarding in time of peak hours, when the train is over occupied. On the other hand, vending machines setting up near the entrance of the train will help to provide immediate or unexpected case of encountering smelly people. However, the compensation of setting up the vending machines in train will take up the first seat each row near the entrance. With this plan, it helps people to purchase the solutions more readily.

We decide to set up two machines on each part of the train so that it will be easier for boarding passengers to purchase.

Because the machine will be selling small items for temporary use, we intend to minimize its size as much as possible so that it will not take up too much space in train. Next each since the machine will be set up on train we decide to round the edges of the machine to prevent people from bumping into sharp edges.
