Iterations
Version 1.0
Here is the journey that we took to get to our current design iteration. Originally, we were basing the design off the PCB and an axial fan. This caused the buttons and LEDs to be on its side. Due to these reason, the enclosure was an inconvenience to medical workers if we were to manufacture the design.
Version 1.2
In the next iteration, we changed the fan, from an axial fan to a centrifugal fan. The reason for this change the exhaust mechanism of both fans. The axial fan will exhaust is not directional, needing an attachment to direct air up the tube. The centrifugal fan solves this issue and provides a simpler design to implement. We decided to reposition the battery to save space and added brackets to hold it in place. We also used the same PCB model due to our timeline restrictions, but we knew in order to save more space and make a better design, we needed to brainstorm a new design around a PCB model with dimensions we wanted.
Version 1.2 - 3D Printed
Version 2.0 - Brainstorm

Our brainstorm for this new iteration allowed us to center our design over a new PCB model. We wanted to change the dimensions of it as well as configure more optimal positions for the buttons and LEDs so that saving space and functionality was implemented. Specifically, we wanted the PCB to be size of the fan that way it could be put behind the fan, and the buttons and LEDs moved to the top of the enclosure for easier access.
Version 2.0
After working alongside the hardware team we implemented this new design. Although this is not exactly what we wanted, we used this as a base to then go into our most current design.
