Tatyana Guerrero is a senior at San Diego State University, graduating in May 2020.  She is majoring in   Mechanical Engineering with an Anthropology Minor.  Tatyana and her teammates are working on the Protective Cap for Upper Extremity Osseointegration Challenge. 

Their goal is to create what in theory looks like an artificial elbow. Currently, there is no protection for those with an implant when a prosthetic is not attached.  The only available item is a 3D printed attachment piece that our challenger is unable to lean on and that provides little to no protection.  Their goal is to create a cap that will attach to the attachment piece and provide protection and comfort to our Challenger so that he may return to sport and leisure activities.

The protective cap they created will have 3 layers: a shock layer made of silicone rubber, a protection layer made of carbon fiber, and a comfort layer made of foam.  Our Challenger asked the device to be attached to the attachment piece given. On the inside, there will be a press-fit casing in which the Challenger can push the attachment piece inside.  There is a spring and rod assembly on the inside and when the Challenger wishes to remove the cap, he will push the button at the top activating the spring and rod assembly and pushing the attachment piece out.

Why did you choose your major?  I chose my major because I have always been fascinated with math and problem-solving.  I wanted to pick something that I could do both things while making a difference in the world.

Describe your experience working with QL+ so far.  I have had a great time working with QL+.  They are extremely supportive of everything and I know what my team and I are creating can help someone which is a very satisfying experience and probably the best reward.  I think our biggest challenge is creating something that doesn’t currently exist in the world right now and so it has been a trial and error ordeal.

What is it like working with your Challenger?  Our challenger, Nick, is great! He is really cool and is always willing to help and provide any information that could be helpful when he can.  The things that Nick has been through and still strives to do all these great things despite that is inspiring to me.  I learned from him and this experience that almost nothing is impossible.  To always strive to make what you want to come true.

What would you say to other students about QL+?  QL+ is a wonderful organization to work with especially in college. Not only do you apply your knowledge to a real-world problem you are helping someone else in the process.  Both combined create an extraordinary feeling.

What are your plans after graduation? 
I would like to find a job that I love in San Diego that can hopefully help people the way QL+ does.  I personally am interested in the role of project manager and project engineer.

What is the proudest moment of your college career?  This project has been the proudest moment of my college career. It made everything I learned worth it to see it go and help someone.

What three words best describe you?  Organized, Caring, Passionate
