About Me
Hi, my name is Bowen, and I study mechanical engineering at Columbia University.

My interests for designing and creating began with my love for LEGOs. As I got older, I let my imagination run wild and started experimenting with different builds. Fast forward to today, I’ve transitioned away from limiting my ideas and tools to just LEGOs ...

Currently, I’m developing a blood pressure measuring device at the Sia Lab and leading a team in Formula SAE to design an enclosure to protect electronics. These experiences have improved my abilities to work in a fast-paced and collaborative environment.

When I’m not tinkering, I’m usually wandering through New York City‘s parks, seeking out hidden gem restaurants, and chasing after Charizard cards for my Pokemon collection.

Projects

Fusion 360 Metallugy Vacuum Chamber
Ongoing ProjectArc Furnace
  • Arc furnaces are used to melt metal and are very expensive
  • Our goal is to design and manufacture a cheaper version of the arc furnace



Fusion 360Optics CAM Signal Processing Spectroscopy
Ongoing ProjectRaman Microscope
  • Raman microscopes, which can be expensive, are used to analyze the material composition and obtain a 3D map of a sample 
  • Our goal is to design and manufacture a Raman microscope as cheap as possible by combining a confocal microscope and Raman spectrometer



CADFEALaser Cut PrototypingSolidworksWaterjet Cut

Featured ProjectCross Member
  • The cross member links components (such as the motor and differential mounts) to each other            
  • Our goal was to minimize weight without compromising safety.
  • Identified initial forces using free body diagrams
  • Identified areas to cut using topology studies
  • Chose a symmetric design for weight distribution and aesthetics
  • Performed static study to check that safety factor was above 3



CADSolidworks Engineering Drawings
Featured ProjectNumber Wheel
  • Our goal was to design a toy that teaches children basic addition and subtraction facts with only single digits as operands
  • In our design, we couldn’t use electronics, small and loose parts, and magnets.
  • Our solution was an interactive toy designed to require neither parental guidance nor electricity.




3D PrintCADElectronicsLaser CutSolidworks Waterjet Cut
Featured ProjectElectric Scooter
  • Our goal was to convert a mechanical scooter into an electrical one
  • I worked on calculating the electronics we needed and performed safety checks on them
  • I also designed the motor guard, brake leveler, battery enclosure, and the speed controller holder
  • In the end, our scooter ran up to 10 miles per hour
