WARRENSBURG, MO – Inspired by action taken by a Canadian youth, two University of Central Missouri students have found an innovative way to provide relief for individuals who experience discomfort from extended use of protective masks. The masks are worn by healthcare professionals on the frontlines of the nation's battle with COVID-19 and are essential for their protection, but the design of these protective items creates a problem that is recently getting a lot of attention. Many individuals who wear this protective gear for long periods of time experience pain caused by rubber straps that dig into the skin behind their ears.

On Monday, April 6, Matthew Argotsinger, Peculiar, Missouri, and Cameron Rogers, Camdenton, Missouri, began production of a new ear guard they plan to contribute initially to Western Missouri Medical Center. Through their volunteer efforts, they hope to serve nearly 600 employees with their new device, 400 of whom are on the frontline serving patients.

Argotsinger and Rogers are both UCM juniors majoring in Design and Drafting Technology. They have leadership positions in the American Institute of Building Design (AIBD) and the Design and Drafting Technology Student Association (DDSA), with Argotsinger serving as president and Rogers, vice president. Both students have been working closely with their instructor, Paul Brown, who is currently teaching the Advanced Parametric Modeling course and 3D Printing.

Dr. Roya Azimzadeh, program coordinator for Design and Drafting Technology, said she was contacted by Argotsinger, who shared with CADD faculty members his thoughts about how the program could make a positive contribution to fighting the current pandemic situation.

“I immediately welcomed the idea and suggested getting started right away,” Azimzadeh said. Students began working in the CADD Design and Drafting Technology area of the Grinstead Building, where they have access to three 3D printers which they used to create a prototype, and continued to produce the first batch of their new device.

Argotsinger said he got the idea after reading about a Canadian boy, Quinn Callander, who used a design he found on the internet to create an ear guard that rests on the back of the head of the individual wearing the mask, and allows the rubber straps to attach to it, rather than wrap around their ears. His story went viral after his mother shared it on social media.

“I saw it on Facebook,” Argotsinger said. “He uploaded the design so that anyone could get access to it and continue on their own. I saw other types of designs, but when I saw this one, I knew this is something we can work with.”

Argotsinger said one of the issues he and Rogers discovered while working with the 3D printers is that production is a slow process. The students hope to produce up to 60 ear guards a day to meet local needs as soon as possible. Currently, they are donating their time and the academic program is covering the cost of the production materials to make the ear guards possible. For students involved, however, there is much more in return for their efforts through lessons gained that don’t always happen in a traditional classroom setting.

“Just reacting fast and appropriately to a situation and using what we have to help the cause” is a great learning experience, according to Rogers.

Argotsinger echoed that sentiment, adding that “Being able to adapt to a situation that keeps evolving and then also manipulating a certain design to make it work successfully, effectively and as efficiently as possible” will help make him better prepared for the professional world.

Brown agreed, noting, “This is a real-world experience for them using a customer that has a demand. They are trying to satisfy that demand through increasing production and productivity. It’s a real good lesson in satisfying a customer.”

While the educational benefits are valuable, all involved are pleased that they are making a contribution to help those who are on the front line in slowing the spread of COVID-19 and caring for those who are most affected.
