For my MAE 2250 course, Introduction to Mechanical Design, I designed the "Swiss Guitarmy Knife" with my Open Design Project group. This was a semester-long design project that involved customer research, brainstorming, designing, iterating, and ultimately creating a functional prototype.
A product that makes guitar maintenance easier
Reduce the barrier to entry for beginning guitar players
Reduce the pain points experienced guitar users have with routine maintenance
Designed with Fusion360
I shared design work with another group member
I was responsible for manufacturing our prototypes
Created a functional capo multitool
Included five tools, a pick holder, and functioned as a capo
Won second place People's Choice design award out of 14 teams
To summarize the design project, I created a webpage to showcase the Swiss Guitarmy Knife, which is included below:
Introducing:


The Swiss Guitarmy includes five tools; three hex-shank bits and two allen keys.
When you order your Swiss Guitarmy Knife, we'll help you pick the tools that are right for your guitar. Got a new guitar? No problem! You're always welcome to buy more tools, at any time, to fit any guitar. With our tool choices, you'll be ready to adjust your bridge height, adjust your truss rod, tighten screws, or fix whatever else comes your way.

Our custom digital instruction guides make it easy to perform any maintenance, and our compact and versatile design allows you to take the Swiss Guitarmy Knife with you, wherever you and your guitar may travel.
The Swiss Guitarmy Knife is a product we're proud of: it's a high quality guitar multitool that looks great and is built to last. Made from only the highest quality materials, the Swiss Guitarmy Knife will be there for you and your guitar, through it all.

Join us as we conquer the future of guitar maintenance.
We started this project with customer interviews, which helped us decide what problem we were going to solve through product design. Throughout this design project, we were guided to return to our customer interviews when making design decisions and justifications. The course structure challenged us to design a product that the customer wanted to own, not that the engineer wanted to make. Overall, this course provided an introduction to customer-focused product design and best practices in industry.
