From the 5 best ideas of smelly people in train we developed into two combination ideas, there are fragrance chair + oxygen mask and vending machine + smell sensor

Fragrance chair and oxygen mask

We decide to combine these two ideas because we want to give more choices for passengers. If fragrance chair may produce uncomfortable fragrance to some people, passenger can choose to use oxygen mask, which would be installed in a cabinet underneath each chair. As the chairs produce the fragrance, it will spread into the air thus reducing the bad smell in the air.

Vending machine and smell sensor

Our idea is to create a machine that can both detect the problem and at the same time offer solutions to the problem. A vending machine seems to solve the problem as it can provide a variety of solutions to people who are aware of their body odor, and suffer from it.  The smell detector will be installed into the machine so that the vending machine will act as a doctor to detect and offer temporary solutions such as new t-shirt, candies, deodorant, and perfume to smelly people. On the other hand other passengers can purchase different items to avoid smelly people such as mask, small perfume, candies.
