In ENGR 2156, Sophomore Design, I would like to design a lipstick container. The current lipstick design has product left in the tube that you can not get out. This causes product waste, because you can not use all of the product in the container. This problem also happens in chapstick tubes. If the design was changed to have no waste, or less waste, then the consumer would be able to get more for their money. The manufacturing of the product itself would not have to change the amount in the container, therefore it would be no additional cost to the producer of the lipstick itself.
I want to change the design, because currently lipstick tubes are still similar shaped to the original design. The only thing different is the dimensions, or look of the container. However they are still operated the same way, by twisting from the base and pushing the product to the top. Once you use the lipstick, there is still a small amount left that you can not use without attempting to take it out of the container. Lipstick containers only purpose now is to incase the lipstick, and they are made aesthetically pleasing. However, I want to change it so the container itself improves the use of the product itself. The container should allow for ease of use, less product wasted, and protecting the product itself.
Restraints I have in the design would be the cost of manufacturing. As the cost would need to be cheaper or equal to the current manufacturing process. Also, the design has to be able to be easily held in the hand and applied. Another restraint is the amount of time I have to come up with a design.
Assumptions
One assumption is that the user has to be able to work the product themselves by hand without any power from an electrical source. Another assumption is that the casing of the product has to be study enough to not bend, in order to protect the product. My design will start from the current design of lipstick tube and modify it.
Gantt Chart
Strategy 1
In Strategy one the design is based off changing the shape of the applicator, and the way the product is held to use less product. The angle of the top, and angleing the bottom of the lipstick bullet will allow the product to be used evenly across an angle. The product is twsited up from the bottom.
Strategy 2
Strategy 2 is designed to be used one handed. The top is a pop top, and it is connected to the body. The product is pushed up with a lever. It will have notches in it to push the lever in so it does not push back down when you use it. the lever will allow the product to be directly pushed up from the bottom. This will reduce the amount of product held, which will increase the amount used.
Strategy 3
Strategy 3 is focused on changing the way the porduct is held inside the container. In this design there is no plastic holding the lipstick bullet, it sits directly inside of case. This will reduce the amount of material used in the design. Removing the inner casing will allow for the lipstick bullet to be set inside, not held. The device will still twist up from the bottom.

Lessons Learned One of the main lessons I learned was to make the Gantt Chart to plan out your assignment. This will prevent you from starting the project a week before it is do. Also during this assignment I had to remember how to do Gantt Charts form ENGR 1201. I learned what a FRDPPARC table was and how to use it to develop a product design. Another lesson I learned was how lipstick tubes are made, and how the first design was patented. |

-Good job coming up with a product that fixes a problem that directly impacts high schools
-Maybe make your Gantt Chart open is a separate tab so you do not have to go back after viewing it
-Also, you could make your FRDPPARRC tables larger so they are easier to read
-You could reword the sentence underneath power equations, because it is slightly confusing to read.

Comments
-Good Problem statement explaining while you are passionate about your project
-Add constraints so it shows the limits of what you an do
-If you want your device to be geared toward all ages, are you going to have a way to scale your design based off age?
-Maybe add information about how current prosthetic are designed, and if you referenced any of those ideas.
