Jelly Bean Dispenser
Problem
It is the Starbust Candy Company's 50th aniversary and they would like to provide consumers with a candy dispenser that will house their Jelly Beans. They want it to be high tech and fit inside most shelves at grocery stores. Design and model a new hand-held dispensing system.
Constraints
1. Must be durable
2.Must not have a footprint size that exceeds 4" wide x 4" deep x 4" high
3. Must have a minmum of four different parts once assembled.
4. Must include tolerances of at least .025in on moving parts.
5. Must hold at least 1/4 cup of jelly beans

Brainstorming/ Sketching
This project was excellent for coming up with funny and creative ideas. We had a lot of different ones, like cup-like ones or rolling ones, but we ended up with one that could be held easily in the palm of a child's hand. Plus, the child can take off the top and middle and play with it if they wanted to. The distance between the dish and the main house is large enough for adults to get their fingers in and also for a child to get their whole hand to it. Here are a few of our ideas below, along with the final sketch of our final idea. A few of them were decided without me when I was gone for a festival, but I believe that we made the right choice in the end.
Final Idea
Here is our final idea as a sketch. I dimensioned and drew it myself, but we had to go back a make a few changes for the better, like removing the axles and wheels. The wheels were too small and the axles could be easily lost. The windows and door are actually on the prototype, but they don't actually do anything, like open or move. We decided on this idea because we felt it appealed the the childness of the kids. They can actually take off the actual house itself and play with it when they don't have jelly beans or any other type of candy in it. It is also usuable. The handle on the bottom is large enough to where it isn't a choking hazard. We also chose it because it seemed more interesting that the other ideas that we had. It is more captivating to the children than what a box or a cup would be like. The kids would be more interested in our idea than anyone else's.
Final Drawing Sheets
Below are the final drawing sheets of the different parts and full assembly of our project. I did everything from the bottom down and my teammates did the main section and the lid that looks like a roof. It was a little difficult creating these different parts on Inventor and we had to go back and change a lot of things, but we came through in the end. We did remove what we formerly had on there as the wheels and axles and I believe that it is better this way. It is a lot easier to handle and can comfortably fit in a kid's hand without rolling off or moving.
HandleThese next two things were some of the easiest I've had to make. This handle for the full handle was just a revolve of a design around an axis.
Above is the Inventor model of the handle piece. This wasn't as difficult to make, but the slot where the flat of the handle was supposed to go in I had to change multiple times to get it to fit perfectly. I had to adjust it width wise and also move it on the bottom so where it would line up evenly with the flat surface.

Flat of HandleThis was the easiest thing to make. As you can see, it's just a flat surface and that's really all it was on Inventor.
The rendered modle is almost life size for the handle. It is approximately that thick and that wide, if not just a bit bigger. The thickness of the handle was .04 inches and I believe that it will hold up a fourth of a cup of jelly beans just fine.

This is the completed Inventor model. As you can see, they fit together perfectly and they turned out just as good.
This was the prototype that I had our teacher print off for us. It was a 3D model of the completed handle assembly (above) and I painted it nicely once I got to class the next time. I thought the fun design of the handle would also be playful for the age group that we are aiming for.
|
Assembled PrototypeThis is the fully assembled, 3D prototype. There are five different parts on the prototype. The dish and the middle are connected so they are more stable when placed or moved. The handle is inside the slot that it needed to be inside and it won't fall out accidentally or move unless you pull on the small handle with your fingers.
|
Inventor AssemblyThis is the completed Inventor assembly that I did. The colors are slightly different, but the brighter and more colorful colors on the prototype are better to look at and more fun for the children. Before we could fully complete this Inventor assembly, we had to go back and fix a few things, like how big the roof was and trim a few millimeters off of the edges on the middle of the bottom. But other than those things, the dimensions that we first took fit perfectly.

Below is a clip that shows all of the different parts of the assembly. It shows them apart and shows them coming together. You are able to see all of the difference pieces that created this final product.
Why Should You Choose Ours?
Testing/ Final Result
We tested our prototype out with the jelly beans that we are supposed to be able to dispense. I was given a handful of the jelly beans and I placed them inside of our prototype. Everything went as expected. The jelly beans were stopped by the handle and as I drew the handle back, the jelly beans fell through them middle and onto the dish. The handle was easy to put back with jelly beans on it and it can dispense as many jelly beans as desired by the person using it.
Conclusion
Being difficult at sometimes, but easier at others, this project was actually a really fun one. We were able to work together easily as a team and come up with what I believe to be an amazing prototype jelly bean dispenser. We designed together and worked hard, and we were able to get it done in the end. It was fun to see that our jelly bean dispenser actually come out as something real, rather than just have it on the computer for everyone to see. I believe that the Starburst Candy Company would choose ours because it is fun and easy to use.
If I could change anything, I would probably change the middle of the bottom. How we have it now is good if it were hanging, but bad for sitting on a desk. I would change it to where there are indents in the figure so it holds steady on a solid surface. I would also make the dish walls slightly smaller so they could get to the handle a lot easier.
