Our Product Status (Yaqi Huang)
This week we did a lot work on the project.
Everyone is hard working. First of all, each member votes to pick up the top
five ideas. And we made a design matrix with that five ideas and the datum.
Through the design matrix we decided our final concept. It is hard to decide.
We have 12 ideas, and we love everyone. So based on the results of matrix we
combine some concepts. Our final concept is based on electronic teeth brush.
Then we did function decomposition to make every parts of the product clear.
According to the function decomposition, our product will have two independent
systems, “scrubbing ice” and “spraying deicer liquid”. Basically the idea is
once a button is pressed the electric energy will transfer to mechanical
energy. And the Mech. Energy will start the rotation and vibrating motion of
the brush. And there will be another button on the product. Once you press that
the button, the deicer liquid will be sprayed. What’s more, we are building the
prototype right now. Although we haven’t finally done it, we already have the
picture in our mind. And we are looking forward to our prototype.
Another thing for our team, we made norms.
As time going, there is a little conflict in our team. So to make everyone
happy we made some regulations:
Everyone should focus during
lecture
No Michigan time, but maximum
of 10 min tolerance
Everyone should speak English
even we are Asian team
Get the task assigned done on
time
Improve the communication. Keep
the report consistency
Pay attention to the group
meeting
Editing report together
Interesting Finding (Ivan)
This week we meet up with professor Luntz
to talk about our project ideas. Other than the initial 12 methods we discover,
he actually mentioned about hydrophobic liquid that we can integrate for our
car cover and/or blanket ideas. This liquid is actually on the market already
right now with a product name called neverwet. It was meant to be applied for
daily life utilities such as preventing shoes from mud or rain water, farming
gloves, and so on. Looking at the promotional video, it actually looks preety convincing.
However,
the team think this solution is too easy and not too mechanical-ish, so we
proceed
with our oversize electric rotating toothbrush concept and thus pitch
this idea to prof. luntz
again. He gave us inputs about using both plastic and
brush for the rotating head for a more
efficient result. We also agree to put a
sprayer and a small tank (about 0.5 L) in the brush
handle for deicer liquid
application. We are planning to install two switch/button on the handle in
which one will turn on the rotating motor, while the other will spray the
liquid. We will see how
good our design later in the week.
Future Plan (Steven)
In this week, our team spends a lot of time
completing the activities for GR2. We finish the functional decomposition,
concept sketch, and concept scoring matrices, etc. By next Thursday, there are
three important issues to finish, building alpha prototype, GR2 proofreading,
and GR1 revision. Two of our teammates will go to the design lab 1 making the
prototype by hands, and the others will help do the GR2 proofreading again and
again to ensure that we won't face too many grammar errors as GR1. For GR1
revision, we will take it to sweetland and revise it ASAP. Hope we can do a
good job in GR2 ~
