In this memo describe what you learned, what challenges you had in completing the assignment
and whether you utilized AI to help in your learning. If you used AI please describe how.
I learned a lot more about how exactly air conditioners work, when compared to “air coolers” or
coolers in general. I learned more about the engineering behind the portable and how easy
manipulated it can be. I had trouble deciding what product to choose and what/how I can modify
it. I did not use AI but I used different articles and youtube videos to learn more about how the
product works and how I can make it better. I also researched different engineering
advancements and failures with articles. [Conclusion – End with a call to action.]

Product or Device Presentation: “The Demo Minute” Think of an engineered product. This
can be any product you like or dislike. Write a paper (no minimum or maximum word
count required-write what is necessary to be complete) describing the product, its’ design
features and why you feel it is good or bad. Discuss any improvements you would make to
better the product, you must make at least one improvement. Please include a simple
sketch of the improved product or a picture.
The product I chose to write about is the portable AC Cooler by Chillwell. I chose this product
because of a very negative experience I had with it earlier this month. Rooms without AC are
very common here in Boston and other campuses across the country. The chilwell is a portable,
energy efficient “AC” that is advertised to cool a room within seconds and will take a room from
being 80+ degrees to 70 degrees and under. The chilwell cooler uses cold water with ice and a
cooling frame to cool down air that enters through the fan from one side, and evaporation then
cools the air which comes out the other side. I think there are both good and bad aspects to this
product. One thing I like about the product is how small/portable it is. I also think it is a great
option if you are trying to conserve energy, money, and electricity when compared to an AC
Unit. However, the problem with this product is the functionality. The idea of refilling the cooler
every couple of hours with ice cold water is unrealistic and a hassle. The machine is also
extremely loud and shakes while it's being used. The water also leaks from the machine because
the opening from the reservoir is not closed off and can seep through the fan. It also is not
good/functional when used to “cool an entire room” despite the advertisement. When my friend
used it to cool down his dorm room he found himself having to refill it every hour and not
having enough ice to put in. And the temperature of the room barely went down by 3 degrees.
Similar to a swamp cooler, this portable AC cooler adds humidity to the room because there is
nothing removing the moisture from the trapped cooled air (which an air conditioner does). If I
were to make an improvement to this product I would make the
fans stronger and I would create an excess moisture pipe to remove
the humidity like an air conditioner has
How an Air Conditioner Works :
“Warm air from your indoors is
blown over the cool evaporator coils, and this meeting of warm air
and cool air creates condensation. This condensation collects on the
coils and then drips down to the condensate pan for removal by the
condensate pipe.”

Societal Needs For Engineering: (20 Points) Identify three types of societal needs that
engineering has satisfied. Discuss the degree to which these needs have been satisfied. If the
need(s) have not been fully satisfied by the engineering solution(s), discuss the possible
reason for this less-than-optimal result.
Food, Shelter, and Technology (maybe not a need but very important)
Food: There have been many advancements in the food industry when it comes to engineering.
One example could be GMO’s. There are different GMOs that can make it possible for food to
be easily grown and administered. And there are different GMO’s that can help with dietary
restrictions/allergies. I don’t think this need has been completely satisfied because there is still an
unhealthy side to GMOs. The reason for this is because the chemicals used in GMOs are not
good for the human body.
Shelter: Engineers have been able to satisfy a lot of different sheltering needs. Engineers have
been able to build insulated homes that include heat and AC. There are many homes that can
withstand different severe weather conditions and natural climates. One way that this need has
not been completely satisfied is that there is not much equality when it comes to safe and
advanced homes. There are many neighborhoods and countries where safe, affordable, and
advanced homes are an option. There are people around the world who don’t have access to safe
housing. I think this is mainly due to the fact of lack of resources. There are many lower
income/less developed settings where engineers and resources are scarce.
Technology: Engineers have been able to build devices that communicate across the globe. I
think there have been so many different advances in technology in so many different scenarios.
One thing that I think can be developed more is AI.

Engineering Failure:
An example of an engineering failure is Oceangate. There were multiple different underlying
causes for this failure that I believe were all avoidable. Oceangate failed because of lack of
design, testing, and research. The material that Ocean Gate was built out of was not able to
withstand the ocean. The design of the submarine was not well designed enough to be able to
communicate with the surface and withstand the depth of the ocean. And there was not enough
testing on the submarine to be able to carry passengers and go into the ocean. This engineering
failure was definitely NOT inevitable. And more planning, research, and testing could have
avoided this
