Comments on function-related aspects

Client 1:

This is a nice, simple submission for your deliverable. It sounds like you adapted well to the modifications that were made based on the sketch model research.

I would have liked to see something about how the plate attaches to the vacuum mechanism as well as the caster wheels. I have a concern about this whole vacuum tipping over if it gets caught on one of the hoses, and I would like to see the mechanism in the same diagram as the base to see if that is actually a possibility. You may have to consider using a skirt around the wheel base to prevent this, and maybe even widening the base in relation to the vacuum mechanism to make it very difficult to tip over.

Reviewer 2:

This is a pretty standard design that would be able to fulfill the requirements of the Vacuum. As there would be a powerful fan used to blow the money in the box, I would recommend that some type of shield be implemented around the vacuum base or at the air inlet/outlet to prevent players from sticking their hands in there or accidentally dropping their items and having it sucked up the hole.

Reviewer 3:

The functionality is clear and both fabrication and assembly appear straightforward. One item that is not clear is the material and properties of the wheels. The overview mentions them being shock-absorbing, but it's not clear that there is any such mechanism - is it just in the nature of the material used for the wheels, perhaps because they will be made of a soft rubber?

Reviewer 4:

Some things to think about are how to prevent this from going over people's feet and prevent any excess force from causing the vacuum from moving out of control.

Comments on form-related aspects

Client 1:

I don't have too much to say about the form aspects of your work other than that your rendering is clean and simple. Good job!

Reviewer 3:

The assembly is fairly simple, so the solidworks rendering is sufficient to illustrate the point. Aesthetics do not appear particularly critical to this element as it is a base for the rest of the device which will interact with players. In terms of human use, the team may want to consider further how players will interact with the wheels. It seems there is some risk of getting feet and hands under the device because it is elevated on wheels; this may increase tipping and turnover risk.

Reviewer 4:

The form is very straightforward. You were able to well justify why the part is the way it is and showed a nice render of it.
