We Bring Good Things to Life

Engineering students showcase elegant solutions to real-world problems at Capstone Design Expo – VCU News

From 2015 to 2020, there were at least 2,070 unintentional shootings by children, resulting in 765 deaths, according to the advocacy group Everytown for Gun Safety. The group’s research shows that one in four of these shootings was by a child five or younger. One in four of the victims also were five or younger.

Many of these incidents occur when young children find a loaded handgun in the home and mistake it for a toy. Use of trigger locks or a lock box can prevent these tragedies, but many gun owners fail to consistently use them. 

The prevalence of these incidents motivated project manager Zoie Sickey and her team, BME 106, all biomedical engineering majors at Virginia Commonwealth University, to choose a project related to gun injuries for their Capstone Design project for the College of Engineering. It’s title: “Preventing Unintentional Gun-Related Injury and Mortality: A Low-Cost and Accessible Gun Safety Device.”

“The project not only sounded really interesting, but the overall issue of preventing unintentional gun-related injuries was a topic that I felt not only needed addressing but is something I have a personal connection to given that I grew up in a household with firearms,” said Sickey, a senior.

Art Kellerman, M.D., senior vice president for VCU Health Sciences and CEO of VCU Health System, first posed the project to Barbara D. Boyan, Ph.D., the Alice T. and William H. Goodwin, Jr. Dean of VCU Engineering, last summer. 

“As an emergency room physician, he was concerned that children were unintentional victims but that he was confident that engineering students could, indeed should, bring their innovative intellect to finding simple and viable solutions to the problem,” Boyan said. “As a biomedical engineer myself, I was confident that Team BME 106 would be up to this challenge. Their elegant design does not disappoint.”

Capstone Design Expo offers teams the opportunity to display and demonstrate their prototype

A signature event of the VCU College School of Engineering, the annual Capstone Design Expo represents the culmination of the graduating class’s education and offers design teams the opportunity to display and demonstrate their working prototypes to the Greater Richmond community. The event also serves to increase the awareness of the engineering profession among middle and high school students. More than 375 students participated in this year’s event.

The projects are the product of a yearlong Capstone Design course, led by Michael C. Mancini, Ph.D., director of project outreach and the capstone program, which immerses senior engineering students in the hands-on processes of solving practical real-world problems.

Through their projects, student teams practice customer discovery, the engineering design process, and rapid prototyping. Working with sponsors, students tackle this practical learning experience by solving real-world problems under real-world constraints, learning fundamentals of teamwork and applying learned theory.

Keeping children safe from unintentional gun injuries

The work from Team BME 106 exemplifies the capstone teams’ focus on addressing real-world issues with sophisticated solutions. The team was concerned that new gun owners lack the proper knowledge and training for handling and safely keeping a gun in their home, said senior Corinne Leonard. 

“Unfortunately, when this occurs children can fall victim to unintentional gun injuries and deaths. This concern drove our motivation for the project to create a device that would cater both to gun owners, by being easily accessible, and parents to keep their kids safe,” said Leonard.

“Many gun owners believe that it is more important to be able to quickly reach a loaded handgun for self-defense than to eliminate the risk that their child, or a visiting child, might find it,” Kellerman said. “Studies have found that parents tend to underestimate their children’s curiosity and their tendency to play with forbidden objects. The VCU team set out to find an engineering solution that would solve both problems: provide ready access to the adult in a way that prevents the handgun from being fired by a young child.”

The Zore X Core is a gun lock with a mechanism that blocks the firing pin from meeting the ammunition and prevents the slide from fully closing. The team worked to create a product that would allow for the lock to stay attached to the firearm and allow an automatic transition to remove the firing pin block. To prevent children younger than 10 from the unlocking the device, the team intends to use mechanical switches or pressure sensors that react only to an adequate amount of force – an amount of force larger than a young child could muster.

The project presented several challenges, especially for senior Kelly Salguero and Leonard who were faced with learning the mechanics and lingo of firearms.

“Luckily for us, Zoie and [team member] Brianna [Roberto] had experience with firearms and were happy to answer any questions we had,” Salguero said.

Another challenge the team faced was not being able to have access to the gun, Glock 43, or a 3D-printed shell of the gun to help them create a prototype for the project.

“I personally am a visual and hands-on learner, as I believe most engineers are, so it was difficult for us to prototype by solely relying on a CAD model or image,” Leonard said. “This was something that really couldn’t be mitigated because of restrictions set by VCU, for obvious reasons. However, we managed to prototype to the best of our abilities and with the help of VCU police we are able to have access to a Glock 43 under supervision.”

The project was a learning experience for all four team members who were able to collaborate with people they would not ordinarily have met at VCU, Sickey said.

“I definitely learned a lot more about firearms in general through my work on this project, especially in terms of the safeties internal and external already in place and why people are so apprehensive to use them,” she said.

The project also had a personal meaning to Roberto, who has a 2-year-old son.

“I could not imagine him getting into our firearms by accident or not,” she said “I want all parents to have access to safety mechanisms, so children aren’t dying from unintentional gun deaths. I hope this project spreads awareness about this topic and more research is conducted.”
