Hello my name is Katelyn Cockerham, I am from Taylorsville, NC. My small town is located about an hour from Charlotte. Most of the time I am either out somewhere in the woods mountain biking or doing homework. This is my second year at UNC Charlotte, and I am looking forward to the upcoming years here. My reasons behind choosing to study mechanical engineering was because, when I was younger I was always interested in the process of how objects were made and their purpose. Additionally, I enjoy how broad mechanical engineering is and the problem solving that is associated with it. Overtime, I have noticed I have developed many different interests since I started my degree and one of them is the designing process of prosthetics. Therefore, I look forward to learning more about the 3D design process and how to implement my skills into designing a prosthetic one day.

In the past 150 years there have been many engineering designs that have greatly impacted society but in my opinion the three that have made a big effect on mankind would be magnetic resonance imaging (MRI), the refrigerator and 3D printer. Magnetic resonance imaging known as MRI is a form of viewing the inside of the body without having to perform surgery or without being exposed to x-rays.This has dramatically helped society over the years by allowing physicians to be able to diagnose diseases and treat these diseases in earlier stages. The refrigerator has also made an impact on mankind by allowing for people to preserve and store their food in a cold place. This invention has helped slow down the activity of bacteria because of the cold temperature. Lastly, three-dimensional printing has benefited humanity in many ways. Especially the medical field, 3D printing has allowed for low-cost prosthetics to be made along with other medical implants. This machinery allows for these implants and prosthetics to be customized and produced quickly.


Design Analysis of the Broom:

The main problem the broom solves is a cleaning implement for sweeping various surfaces. The authors of the broom are patented by Juan Fernandez.


Geometric Effects:

The upper portion of the broom consists of a cylindrical cover to act as a grip when handling the broom. The cylindrical cover shows there is an oval opening, this is used to hang the broom up.

The second upper portion of the broom consists of a cylindrical handle, the broomstick. This shape allows for the user to easily maneuver the broom around.

This part of the broom is in between the cylindrical handle and the broom head; this is the longitudinal axis. The longitudinal axis connects the cylindrical handle and the broom head.

Different Materials:

1. If the broom was made out of wood it would weigh less compared to the aluminum brooms. The broom handle would have a better elastic modulus compared to the aluminum. The wooden handle would not experience deformation as much as the aluminum handle would.

2. The bristles could either be rattan bristles that are stiff compared to the broomcorn bristles that are known to be softer. The rattan bristles would be more suitable to sweep wet leaves while the softer bristles are used inside homes to sweep dust.


Other Solutions:

1. Vacuum: CLICK HERE for a patent

2. Robot Vacuum: CLICK HERE for a patent


Manufacturing:

Brooms are manufactured globally. The broom is manufactured by having the bristles already produced which is made out of stiff fibers ( plastic, hair, corn husk, etc.) and ready to be attached to the cylindrical handle that can be made out of plastic, aluminum, or wood.


A problem I would like to solve for my 2156 project would be desiging a cover for candles. I always have the issue of leaving my house and my candle still be lit and I have the fear of it accidentally being knocked over and causing a fire. So if I could come up with some design to cover my candle and still be able to let it burn without worrying about it causing a fire would be great. That would allow for me to be able to burn my candle however long I want without the worry of causing a fire.


I have spent a total of 10 hours on this assignment.
