Assignment #2: Jeff's Disneyland Cup
My goal was to create a water container for the different areas of Disneyland. The differences between these areas, including main street, toontown and tomorrowland, dictate the variables in the container. Although I started with many more variables, some of which I liked more than those implemented, the complexity of relationships meant I had to simplify. I am amazed at how many unseen relationships need to be defined to allow for two variables to be manipulated without conflict. In this model I eventually settled on 4 variables, which are listed below.
Driving Parameters
avg. height requirement_ a larger average height means a larger average in hand size: changes the diameter of the cup
crowd size_ the more people around the more likely that something unpleasant will land in th cup: changes the opening size
mickey frequency_ mickey hangs out in some areas more than others: changes the ear size
Souvenir quality_ not all souvenirs are made equally, not all shops are equal: changes material thickness (i know, this one is kind of made up)

Parametric variations: Images

 |  |  |  |
- solidworks images
 |  |  |  |  |
Lessons learned
- A successful model has numerous unseen parameters which have to be established for the model to work
- A logic map can be invaluable, and should be updated as a model is created
- Everything takes 4x longer than you think it will
- Name everything… and I mean everything.
Discussion
Yet another interesting piece of work this one. I appreciated the fact that your logic diagram appears to be a scanned note instead of perfect squares from some MS application. (Like mine always seems to turn out being.)
I must also give you credit for a set of very nice rendered pictures! Well done!

Would be great if you could show some slides from the CAD model in addition to the renderings
What an innovative idea! Like Thomas, I'd be interested to see you CAD model because I'd like to know more about how your model started - did you draw it in profile and create the design from there? I'm assuming you in fact had to do something more complicated to get the ears to repeat at the angle they do without repeating around the whole cup. I'd be interested to learn how to do this.
I'm also fascinated by the way you've done your opening. I appreciate the way that it expands from an offset but am curious to see how exactly this was integrated into your design when you started from square one. One thing I enjoy about your designs is the way that your goals and design drivers were focused on the park and things that could possibly happen to your drink while at the park but these changes given your parameters also change the design into different types of cups that would be ideal for different types of beverages - water vs. a smoothie vs. coffee.
The cup 2nd from top right is neat - I like the sunken opening. When looking at that design and your bottom left configuration, it seems that you could put them together to make a new kind of spout that could even become a mickey pitcher.
Really nice work! Your models seem to be a very marketable idea… I'm also curious to know how you achieved these results.
I guess you can se one of the drawbacks of working in a heterogeneous CAD environment (you on Solidworks) in that your models can't really be shared in their intelligent parametric form for others in the group to explore and investigate. This is however a reality in our world so it puts an even greater emphasis on expressing your logic and fundamental geometry in a format reusable by others (diagrams, etc).
Solidworks, huh? Since I have zero CAD experience outside of this class, looking at your design was super interesting. I like that in your presentation you acknowledged the fact that parameterization makes iterations more reasonable and accessible compared to free sketching or drafting. It sort of forces you to make your work something that other people can manipulate logically and effectively.
I liked the fact that your design was not symmetric. This design clearly lent itself to simple revolves with the spout in the center. You managed to make it work to your advantage to further the usability of your container and aesthetics in the real world. Strong work!
When I listened to your presentation, I said “WOW~!” I love your models and I want to learn how to use a Solidworks.
Min, the reason we chose DP over Solidworks is that it is actually a lot more flexible and can deal with large assemblies/products in ways that SW can't. As for the rendered images - DP actually has Mental Ray as renderer (same as many animation packages use 3DS Max, XSI, Maya, etc). If you want I can show you how to use the module.
For the next assignment, I would like to spend more time with digital project as it definitely seems to have a lot of power. And although I have some experience with Solidworks I am still fairly new at it compared to other modeling programs, which is why i stuck by it for this assignment. Most of my experience is with surface/poly modelers, (Rhino, 3DS Max) and Auto CAD.
DP definitely seems to be better suited for larger and more complicated projects. Also, Mental Ray is a definite plus.
I really liked your “mickey factor” design. I thought it was not only just a fun factor, but it also created a great design. I was a little frustrated when I first saw your slides because you did such a great job compared to me, but knowing that you have more experience made me feel a little better. I think the Solidworks has a better presentation ability than DP. I think Solidworks is definitely a program that I should try to learn myself.
