Today
we presented the final presentation of our technology project-Brake Cooling
System in the class. We described every important process of our project in
detail and showed the video of our project to the classmates and lecturers. Unfortunately,
we made a major mistake in our presentation. We forgot to describe that what is
our project and the purpose of our project. Because this is the first time some
lecturers had taken our presentation, they did not know what our project is. Thus
some lecturers still were confused about our project after the presentation
done. This is our major mistake, which will remind us to prevent same mistake
from happening again in the future presentation.
Since
we determined our technology project, we almost spent one semester time on this
project. In this process, I learnt some new knowledge and skills from this
project.
Our
project can be divided into two parts, the electronic and mechanical. Jin and I
are responsible for the mechanical part of the project. In the beginning, I thought
that find the suitable components for our project will be very easy, but in
fact it was not easy. Before we looked for our components, we already measured
and got the approximate dimensions for those components we need. After we got those
components and tried to install on that existing project, we found that these
components are not very consistent with our requirements. The problem was that
we did not consider thoughtfully for the whole project. When we considered
about some components dimensions, we did not take into account for another
components dimension. So it causes components cannot be installed in the right
position, and components are stuck. From this experience of doing technology
project, I know that we must carefully consider all aspects of the project and
carefully measure the components dimensions before we look for our components. This
will reduce trouble and save time for us. I also learnt how to manage the time
and money and how to process a project. This will be very helpful for me in the
future.
In
our project, we also used some knowledge and skills we’ve learned before, from
the Brake class and Electrical and Electronic class. In our project, we must
consider the temperature of brake failure or brake fade. We found the brake
failure temperature by searching some books and internet. Then we should allow
our project to spray water mist throughout the ventilated rotor to cool the
brake rotor temperature down before it reached the warning temperature. By
using some knowledge we learnt before, we use the formula to calculate the
amount of water the nozzle need to spray, this allowed us to choose right tank.
We generally responsible for mechanical, but we also participated in the electronic
section. We need to connect a lot of electronic components in the circuit board,
such as transistor, temperature sensor, LED and so on. These we learnt from
Electronic and Electrical class.
For
the personal limitations, I think I am good at on the time management. Our
project has been successfully completed one week before final presentation
start. But in the progress of the project, I also exposed many personal
limitations. We only can apply some simple formula to calculate the data, it
will cause some error. The project will be not very perfect. To edit program cost
us a lot of time, because we do not very good at programming. We also do not well
at electronic. We wasted about 80 dollars in some useless components, because
we do not plan our project well.
To
do this project gave us many experiences, we consolidate the knowledge we
learnt before and we also learned new knowledge and capabilities, and apply
them to our project. In the future, I need to learn more knowledge about
electronic, which will be very benefit for my next year course.
In
the end, I am very grateful to Roman and Simon to give us help.
