Jme 4110: Door Cycling Station, Briana Kagy, Alexander Clark, William Todd, Seth Flamm
Washington University / UMSL Mechanical Engineering Design Project JME 4110
The objective of this project was to design and build a door cycling station to be used for fatigue testing commercial refrigerator doors, including the door gaskets, hinges, and handles. The system must be low maintenance and reliable for at least two million cycles, and it must fit within the provided budget. The design concept includes a rodless pneumatic cylinder and a system of wear-resistant ropes, eyebolts, and pulleys.

Jme 4110: Upgraded Refrigeration Door Cycling System, Keenan Bland, Kelvin Woods, Tyler Mclaughlin
Washington University / UMSL Mechanical Engineering Design Project JME 4110
This project focuses on improvements to a door cycling system. Both a fortified rope for the pulley system, ensuring extended operation, and the integration of a support track. This track is designed to bolster the clevis linked to an air piston that facilitates smooth piston rod travel without deflection. With these advancements, our door cycling system attains a new level of reliability, durability and functionality.

Jme 4110: Rain Barrel Irrigation System, Micah Oaks, Samuel Fallon, Joshua Dooley
Washington University / UMSL Mechanical Engineering Design Project JME 4110
This project would be to design and build a prototype sprinkler system using rain barrel technology. The system would need to be scaled up to utilize multiple barrels or one large underground tank. Pumps would be utilized to pressurize the lawn sprinkler system. The pumps would be powered preferably by solar power and/or head pressure. The idea would be to create a modular system to be economically deployed.

There are not many, if any, products that tackle an issue every demographic, generation, and person faces, removing a yogurt lid completely and without a mess. For the elder generation, this proves more difficult as the lid is not easy to peel off for a variety of yogurts. Lucky enough, there is now a portable, easy to use product that will solve this everyday obstacle; the Yogurt Lid Remover (YLR).

Jme 4110: Portable Car Wash, Coleman Kaufman, Sara Wilson
Washington University / UMSL Mechanical Engineering Design Project JME 4110
We met with our target customer to understand their needs for the ideal portable car wash. Their key needs included use by any sized passenger vehicle, washing the car as good as a community car wash, and must be portable. We started by researching current products that could match these needs, and then we sketched four of our own designs to match our customer’s needs. With these design sketches we used a metrics tool to determine which design was the best. From there we did engineering calculations to analyze the trouble spots in our design, such as the water pressure …

Jme 4110: Water Reservoir Energy Storage, Kristen Grace, Supapan Thammanok, Leticia Zoratto Lunge
Washington University / UMSL Mechanical Engineering Design Project JME 4110
The goal of this project was to create a demonstrative model of a Pumped Hydroelectric Storage System (PHS). A PHS stores energy by draining water from an upper reservoir through a turbine to generate electricity. This water is then pumped from a lower reservoir to the original upper reservoir to restart the system cycle. Using existing PHS applications, a small-scale prototype was built using an aquarium pump and mini turbine, along with PVC and plastic containers. When water is run through the system, a multimeter can be used to show the power output of the system. In addition to functionality, …

Jme 4110: Data Cooling Center, Christopher Schmidt, Brennan Fogarty, Suruchi Aryal
Washington University / UMSL Mechanical Engineering Design Project JME 4110
The group will design a way to efficiently move heat within a framework of using dielectric fluid as a heat transfer medium. The heat will be removed from a data center or a simulated data center. The group will evaluate the best possible design with the understanding that cooling data centers generate a large amount of heat. The design will also be constructed in such a manner that it can be scaled up to a larger size. Dielectric fluid will be used due to its efficiency compared to that of an air cooled system or a compressed refrigerant system. Account …

Jme 4110: Mass Production Of Multi-Sphere Approximated Parts, Christopher Hartley, Chad Gorski, Matthew Brady
Washington University / UMSL Mechanical Engineering Design Project JME 4110
For this project, the team needs to design a mass production manufacturing process. The product of the process will be parts that represent, as closely as possible, approximations of parts developed using Discrete Element Modelling (DEM) software. Since the software uses spheres to efficiently model complex parts, the manufacturing process must also utilize spheres as the building blocks for the approximated parts. As a proof of concept, this project uses river pebbles as the parts being approximated by the software and modeled by the multi-sphere production process.

Washington University / UMSL Mechanical Engineering Design Project JME 4110
As you probably know, there are many different sorting systems used by various manufacturers. It would be desirable to have a similar sorting system that uses multiple technologies to sort items, but that could easily be interchangeable with various items. Currently, recycling efforts are often costly, as humans need to sort single-stream recycling. It would be beneficial to have a system that sorts various plastic, paper, cardboard, glass, etc.

Washington University / UMSL Mechanical Engineering Design Project JME 4110
We are designing and building a working prototype that will be able to mix a separated beverage back to a fully integrated state. This will allow for mixing in a beverage that was separated and would possibly just be thrown away because it doesn’t taste right anymore. This will save food waste from separated beverages being thrown away as well as be environmentally friendly since it would reduce the use of single use cups and straws.

As climate change becomes a larger threat, the idea of space travel becomes a less abstract idea. If we, as a species, get to a point where settling on a new planet becomes a necessity it would be worthwhile for as much infrastructure to be built before our arrival as possible. The problem this project solves is the ability to autonomously assemble piping for plumbing and drainage. To most people, piping is not what comes to mind when thinking about modern living. Although it is certainly essential.

Jme 4110 Phenode Camera Arm Design Project, Kelsey M. Wortmann, Paul Masnica, Matthias Sommer
Washington University / UMSL Mechanical Engineering Design Project JME 4110
The goal of this design project was to create an extendable camera arm capable of attaching to the shell of the PheNode in-field apparatus created by researchers at the Donald Danforth Plant Science Center. The camera arm extends 36 inches in length, can rotate 180 degrees, and successfully holds a camera for plant imaging with minimal vibrations. We have designed an affordable camera arm that is stable and meets the design parameters given. Our design process is documented in the following report.

Jme 4110 Seed Cross-Breeze Distance Tester, Ty Krewson, John Jensen, Emily Dahlberg
Washington University / UMSL Mechanical Engineering Design Project JME 4110
Because seeds vary in shape, size, and weight, their behaviors in cross-breezes vary as well. The customer’s laboratory is researching seeds for prairie grasses. Their laboratory currently has data for seed structures; however, data for seed dispersion is needed to provide a better correlation to known environmental and genetic factors such as precipitation and DNA changes. The Seed Cross-Breeze Distance Tester is a controlled chamber designed to test the distance a seed will travel in a user-specified windspeed.
