TAP II Transportation Project
June - August 2020
During my time working at YourBio Health (previously called Seventh Sense Biosystems), I took the lead on developing a method of shipping hundreds of blood collection devices at once in a safe and efficient manner.

Array of pegs leaves enough room for device "shells" to comfortably sit next to each other.
Tray Design
The hollow plastic tray holds 165 devices on a 12x14 grid of pegs, with the middle three removed. Trays alternate 90 degrees when stacked, and a "lip" is present on two of the four bottom rims to ensure a sturdy fit. 13 full trays holding 2,145 total devices fit in a 2'x2' box, with a 14th acting as a "lid" to protect devices resting on top.

Iterative Process & "T-bar"
Throughout this project, I was in contact with a third-party manufacturer that produced the trays for YourBio. The third party sent samples of various versions of my design that I tested and evaluated as I worked, and along with my co-workers and supervisors, I made design changes based on the performance of the samples and the requirements of the product.
One significant design change that I initiated was the addition of a "plus sign" shaped hole through the stack of trays so that a T-shaped handlebar could be placed through the center for ease of handling. This plus-shape was required since the tray's orientation alternates 90 degrees with each additional one stacked. For the T-shaped bar to fit regardless of orientation, an orientation-independent hole was necessary. The plus-shaped hole also featured a rounded edge to help smoothly guide the bar through a stack of trays.
