GG OWN4GE OP?
Hardly. I'll be earing by BSME Mechanical Engineering this December. Do you honestly think I'd have a question like this for homework? This is the sort of stuff they ask freshmen in the "intro to engineering" class.
Seriously, I bought a 20 oz Vault on campus, and something screwed up in the machine and I got two. As I was hanging out waiting for a class to start, drinking my second one, I was looking at the first one, pondering deep in thought about how well-made the bottle was. The precision with which it is made is beyond what I can do with my own hand tools, and I am unable to melt PET and re-spin it into such nice shapes. It's such a waste to throw out such a thing, especially considering that recycling into new bottles costs energy and money too. Besides, why would I want it to complete the cycle so I can pay over a buck for that same bottle again?
Then it hit me. I started thinking about how much pressure such a bottle could hold. It's designed to resist the pressure of soda when you shake it, and I started coming up with things like a paint ball gun, a paint sprayer, an air horn, an air-powered dremel tool, etc.
My question really hinges around another question: in what other basic functions, other than holding pressure, does this bottle exceed?
Under pressure and loaded vertically, it has a pretty good specific strength.
I really like the floatation idea. With air inside, they have very low density. I wonder how many tubes of epoxy it would cost me to make myself a boat! Now I just need to come up with a really good CAD model of one of them so I can better visualize the assembly. Maybe I could use it as a frame for tarps and stuff. The possibilities are endless.
Have you ever heard of that guy who built himself a house out of coke cans?
Naw, still don't buy it. Even with a nick like kevinthenerd there are too many stipulations in your "prompt" for it to be "I was just thinking...." By that, I mean that you put too many restrictions on what we could come up with.
"The focus should be as a component of a marketable manufactured product rather than, say, reuse for holding household change."
That's teacher/project talk right there. If you were really wondering about the creative ways of reusing a 20 oz bottle, why the heck can't I cut it in half and put some change in there? That way we won't use the energy that would be required to make a new one or recycle it. But, that's not "creative" enough, nor does it constitute a "marketable manufactured product".
Also, if your reason for coming up with this question is environmental or financial (
"It's such a waste to throw out such a thing, especially considering that recycling into new bottles costs energy and money too. Besides, why would I want it to complete the cycle so I can pay over a buck for that same bottle again?) Then I would think that using it to drink from would be obvious, but, you say we can't use that, either. "
You can't use it for drinks unless you can prove to me it's creative"
Now, if you asked "How could I use a 20 oz. bottle to fight zombies in a Mall", then yeah, that's stuff that we waste our time thinking about. In that case, the rocket idea and your Molotov cocktail idea would work. That is how we think (bong, silencer, rockets) and how you yourself think (Molotov cocktail) when not doing homework (i.e. fun). However, a Molotov cocktail isn't exactly "a component of a marketable manufactured product" now is it?
My guess is that you got this assignment in some type of economics or business class that you finally were forced to take the last semester of your senior year. You're confident in your engineering skills, but you are more of a "left brain" engineer (self described nerd) than a "right brain" thinker. That's why you stressed the Creative aspect of the assignment and it is also why you asked on here.
I won't even go into how you automatically assigned any answers you received as having value (because they do to you....your grade) by stating that there is a prize involved (even if it's only PWN4G3). If it was a purely fun/hypothetical question (like the zombies in the mall) then there would be no need for you to explain that there is no prize involved.
To sum up, your BSME Mechanical Engineering will be helpful in using your PIN number at the ATM machine, PM message me if I 'm right (for my own edification - I won't tell), and lastly, do your own homework.
