Mechanical Engineering Projects Showcase Week 2021

Welcome to Showcase Week! We invite you to spend some time getting to know this year's engineering capstone design projects and teams. 

Showcase Week celebrates the hard work and many achievements of over 200 students as they close out their undergraduate and graduate careers. Since August 2020, these students have been working through the design process from start to finish and have engineered solutions to real-world problems. 

Students completing industry-sponsored projects were presented with challenges of relevance to their clients from a variety of specialties. Those in the Engineering for Social Innovation section of Senior Design developed entrepreneurial products based on user needs. 

Please explore projects below to learn more about this year's teams, their designs and the positive impact these engineers are making. We encourage you to leave comments to help them celebrate their achievements and grow professionally. Thank you for your support of our program and students. 

We're incredibly grateful for the support of our project sponsors who make this experience possible. If you would like to learn more about the program or sponsoring a project, please visit Design Center Colorado.

Team 01: Robotic Automation of Cleaning Production Equipment

In the production of aluminum beverage cans, the Ball Corporation sprays an epoxy coating inside the cans before they are filled. A coat of epoxy builds up over time on a ventilation manifold and the nozzle tip used to spray the cans. Our team has created an automated two-part cleaning system using compressed air and a linear scraper to remove epoxy from these components. Our system drops the cleaning time and machine downtime from twenty minutes to five minutes per machine per day.

Team 02: Robotic Automation of Cleaning Production Equipment

During the production of aluminum beverage cans, the interior surface is sprayed with a liquid coating that forms a barrier between the metal and the drink. Over time, this coating accumulates on the spray nozzle tip, compromising coating quality and increasing production costs due to manual removal. We have created an automated solution to efficiently and effectively clean coating buildup.

Team 04: Project WASP

Project WASP explores non-contact methods of measuring silicon wafers for the semiconductor industry. The team developed an automated wafer transfer system enclosed in a test bench and a measurement system to determine surface profiles while the wafer is moving. This measurement must be taken in parallel with existing operations in order to minimize any effects of throughput to the system.

Team 06: Portable Knee Force Sensor

Professional athletes commonly experience patellar tendinitis, a knee injury causing significant pain. To prevent injury, daily tracking of strength metrics is crucial. Current solutions used by the NBA’s Milwaukee Bucks are not portable thus creating gaps in data. To solve this, the team developed the “JOEY”, a Bluetooth-capable, portable solution for continuous strength monitoring.

Team 12: Diameter-Adjustable Vaginal Stent

Vaginal stenosis is a condition where the vaginal canal narrows after surgical management of vaginal anomalies. To prevent this, a stent can be placed in the vagina after surgery to separate the vaginal walls and promote proper healing. Dr. Alaniz at CU Anschutz sponsored team 12 to create a diameter-adjustable stent to prevent vaginal stenosis in her patients.

Team 13: Driveline Securement Device

Left Ventricular Assist Devices (LVADs) are used for the treatment of heart failure. However, all current devices require an external power source with energy supplied by a percutaneous driveline. Excessive mobility of the driveline delays healing and incorporation of the driveline in the subcutaneous tunnel. For this project, Team 13 developed an improved method to secure an LVAD driveline.

Team 16: CNC Workholding with Smart Fluids

One challenge facing the manufacturing industry is the time and cost of creating plugs and fixtures to secure a thin-walled part. We optimized the design of a previous team to create an adaptive workholding fixture that uses a series of magnetic Halbach arrays and an engagement mechanism which lifts the array. The ferrofluid activates and is able to hold the part without any additional components.

Team 27: Condition Monitoring System for Wind Turbine Lightning Protection

Wind turbines are potential targets for lightning strikes. The turbine’s lightning protection system (LPS) is cumbersome and costly to check but needed to prevent blade damage. We have designed an autonomous vehicle that lays a temporary cable on the existing LPS inside a blade. A time-domain reflectometer is then used to measure the continuity and locate potential damages along the blade LPS.

Grad Design Team 02: Tunable Oscillating and Rotational Kinematic Damper

Wind is rapidly becoming a more prevalent source of energy around the world. Simultaneously, wind turbines are being designed to be larger and more efficient in order to increase their output. As the blades on the turbines get longer, unwanted vibrations can cause extremely high stresses within their structures. Siemens Gamesa Renewable Energy (SGRE) has collaborated with a team of students from the University of Colorado Boulder to create a device that aims to reduce these vibrations.
