How will your device demonstrate energy transfer?

-Because the vending machine that I’m making works by rubber band, so it is going to transfer elastic potential energy to mechanical energy.  When you push the handle down, the rubber band(potential elastic) will make the chopstick turn, which will push out the snickers (mechanical).


Is it meeting the criteria/design specifications?

-Yes, the design criteria i chose is “Design and create a device that transfers energy”. It does meet the criteria because the vending machine transfers elastic potential energy to mechanical energy.


How will it function & be aesthetically appealing?

-To make it aesthetically pleasing, i would need to do the cuttings and the measurements precisely and accurately.


What’s its purpose and who is your client?

-The purpose of the vending machine is to have fun when eating a snack! Instead of just grabbing it, this adds a little more fun into it. The client is everyone. It can be for people who wants to have a little fun with snickers or t can be an educational tool to teach transfer of energy!


How are you making your product original or you are using creativity?

-I’m going to make the aesthetic of the vending machine fun and unique, which will make it original. By working on the aesthetic of the box, it will also show my creativity:)


What is the environmental impact of your product?

-Most of the vending machines are made out of plastic, but this vending is made out of cardboard. So it is more recyclable than the general vending machine. Because it is more recyclable, it will definitely make a huge impact on the environmental impact.


How is it durable, yet safe?

– It’s very safe because it’s made out of cardboard. They will not get easily injured by getting hit by, or accidentally dropping it on their food. It is soft and light. But it’s also durable because the hard cardboards are holding up the weight of snickers.
