Comments on function-related aspects

Client 1:

It looks like you learned some important things from your sketch model and incorporated them into this design - that's great.

A note about the servo control of the mesh screen - 1 minute is a really long reset time! Twice that (because you will have to move the mesh back into position) is too long, period. You will need to figure out how to reduce that. I can imagine a design where the mesh hinges along one edge with the other held by an electromagnet. You would release the magnet to drop the screen and let the bills fall into the lower container. Resetting could still use a servo - it would be slightly quicker than your design, but still slow. I'm sure you can improve on this!

I hate to ask so late in the game, but have you considered eliminating the upper screen entirely? I don't know if that will mess up the aesthetics you're going for, but could you get away with just turning the fan on and off to make the bills fly up into the viewing container / fall out of view?

Reviewer 2:

My main issue with the representation is that it's tough to visualize how the system works through reading these big blocks of text. If you could include more visuals (perhaps videos would be best) of how each part works, it would be super helpful! I had to read your description over quite a few times to understand what was really happening, and I'm still unclear on what the appearing/disappearing money would look like (again, videos would aid this). Generally, the design seems well-thought-out, and the decision to divide the subsystem into smaller compartments was a clever one.

Reviewer 3:

This assembly looks great. I also love that you have a working BOM as a team to make things organized and easier as the assignment progresses. If I am being perfectly honest it took me a little while to figure out what was going on here, and some arrows or maybe an advanced state of the mesh moving might have helped me see the motion a little easier. Outside of that, I don't see anything wrong with this system. I might suggest adding a smooth surface on the side of the container that the mesh will be sliding against to help reduce wear and reduce friction. I am guessing that this will be a very flexible metallic mesh? Overall, good work!

Reviewer 4:

I think you've done an exceptional job of translating what you learned in the sketch modeling process into this refined concept. I also think this is a very creative and fun centerpiece for your room.

The functional aspect of this vacuum seems simple (read: robust) and creative. You've put a lot of thought into how to make sure you have smooth and variable airflow through the money enclosure. From what you've designed, I also think this should be very affordable to fabricate, giving you significant budget to invest in the appearance of the room. Great job!

Reviewer 2:

The rendering and exploded view were awesome, and really helped depict how everything is assembled. One thing that could be helpful is including subsystem renderings with each part of the description (even just zooming in on the current rendering would help) so that you don't have to keep scrolling up and down between description and drawing would be really helpful. Overall, really nice job!

Reviewer 4:

I don't necessarily think this model was intended to show off any form aspects of the vacuum, but the solid model rendering and exploded view are clean and easy to understand visually.
