ideation
The ideation phase really challenged the current system and whether it is the best solution. There were dozens of outlandish ideas, however, by doing so, 3 distinctive, innovative directions were found.
proof of concept
To continue with one of the more unproven concepts, I decided to create a proof of concept rig to help test.

concept boards
The two proposed concepts, left and right aim to radically rethink how CPAP devices are used. The left concept, places the device on the user's head, drastically increasing portability and convenience. whilst the device on the right allows the user to wear the device allowing users to use it more.

Charging station for the CPAP headset
concept refinement
Currently only 3 weeks into the refinement. So far there has been an intricate dive into the mechanisms and how best to divert the airflow, to avoid pressure differentials. Also looking into the individual components and how the user will interact with the device.
prototyping
The most recent model is shown on the left. After several models, the front battery storage compartment was placed at the front, to better secure the headset to the head strap. The pictures have been annotated to keep a log of thoughts to convey to others.
developmental CAD
CAD models with varying fidelity, including A sample surfacing, have been produced. In addition to this, along the development process CAD models have been annotated to convey thoughts and ideas.
the solution
Below is the resulting solution after 16 weeks of development. airwave, a head-mounted CPAP machine that improves portability, flexibility, and above all comfortability.
A video outlining how airwave works.
airwave internals
The course has an avid focus on manufacturability and as such, airwave has been designed to be manufacturable. A 200-page technical speciation was also produced.
