In ENGR 2156, Sophomore Design, I would like to design a lipstick container. I want to change the design of a lipstick container to make it more user friendly. However I want the design to be compatible with the current size of lipstick. 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. 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.
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. I want the size of my design to be compatible with the current design, therefore the dimensions must be similar, and able to hold the average lipstick bullet.
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 lipstick bullet itself has to be made of a sturdy material, so the product will not get damaged. My design will start from the current design of lipstick tube and modify it.

Decision Matrix
Based off the decision Matrix I choose strategy number two which is changing how the lipstick is pushed up. My original strategy 2 was more detailed, and for the concepts of it I am going to be more broad to extend the design. I am focusing on changing the way the product is pushed up, and my concepts focus on ways to go about doing it.
Concept 1
Concept 1 will be the original design of strategy 2. Pushing it up from the bottom with a lever. The design will have notches to set the lever in. The cap will pop off, but it will be fastened to the case.
Concept 2
Concept 2 will make the casing for the lipstick slide down from the top. The lid will have threads and screw onto the casing.
Concept 3
Concept 3 will make the casing softer allowing for the packaging to be squeezed, forcing the product to push up. The lid will be made of 4 different panels that intersect at one point, in a pyramid shape. These will fold open when the product is to be used.
Lessons Learned
I learned a few things between the completion of the last assignment and this one. My last assignment was supposed to outline strategies, while mine was very specific and went into the problem on more of a concept level. When doing this assignment I had to use the decision matrix and pick one of my stategries. Once I had picked my strategy, I need to have a broader idea of it, so I could have more variation in my concepts. I learned to not go too into detail at first, because being broad allows you to look at more options to improve your design. Another lesson I learned was to make sure you can view the tasks on your Gantt Chart before you make it into a pdf file.

-How did you decide your device must weigh less than 3 kg?
-You could add hand drawings of your three concepts to visually explain the differences between them
-You could add the actual equations in the analysis portion of your frdparrc tables instead of just saying what the equation is.
-You could also try expanding your frdparcc tables for each design and giving more variation. As each design has the same things for the functional requirements lightweight and battery
