OrthoPedic Bone drill
Spring 2023
Re-engineered Power Tool
In this project, I was challenged to re-engineer a power tool. During this time, I went to Goodwill and picked out an old drill that I then took apart to understand the components of what makes a drill a drill. I then decided to shift my approach a bit to orthopedic drills. I did this because I was really intrigued by the precision and power needed during surgeries and felt like I could create something to improve it! Below will show you my design process from research, ideation, physical models, and even 3D renders.
Research
This section will display my approach to learning about this situation through interviews, articles, videos, and even other products out there!

Interviews
Dr. Khubchandani
Orthopedic Surgeon, Sports Medicine Specialist
-
Specializes in Orthopedics and Sports Medicine
-
Cofounder of the Texas Institute of Orthopedic Surgery and Sports Medicine
Key points during interview:
-
“The bits need a chuck key to go from bit to bit, I would love to see some time of quick connect”
-
“Implants are becoming really popular in the orthopedic field”
-
“I have to use much strength sometimes when working with mallets or drills, finding a more efficient method would be interesting”
Dr. Payne
Dentist
-
Has been in the dentist industry for around 25 years
-
Utilizes medical drills and other tools on the daily
Key points during interview:
-
“Sound is definitely a big issue when working with these tools”
-
“Would love something more efficient, I feel like I have to put a lot back and forth motions when working with these tools”
-
“Cleaning process also breaks down the seal and I have to replace the turbines every 6 months”
Nate
Retired Engineer
-
Volunteers at HeatSync Labs where he works alot with drills
-
Knows a lot about the components in a drill
Key points during interview:
-
“The magnet is really convenient when you need to hold extra screws, but dirt and filament pick up in between the battery and body, and that gets annoying”
-
“When the batteries get to a lower percentage, the drill is not as powerful as it was when it was fully charged”
-
“Some drills now have a hammer mode that I find really helpful when trying to get through tough material like concrete, brick, or stone”

Ideation sketches
3d Physical Models
Using my 3D Printer, I used PLA filament to create my model
I then used a combination of acetone, spot putty and sanding to create a smooth surface
Then with a few layers of spray paint, I created my final 3D model
