Needs and criteria
A Tumor Treating Field Device should be as light and compact as possible so the patient can take it with them because the device must be used for at least 18 hours a day.
It appeared that the device could get hot quickly, so there should be heat sinks that let the heat out directly out of the device.
We had to create a simple user experience so the patients can easily interact with it.
The product had to be released in three pieces: The device, the electrodes, and a bag for the user to carry it. Our team’s mission was to design all three.
We needed to fit the tumor treating board with a massive battery inside a body that looks friendly and beautiful. It also required to cost low on manufacture because it was supposed to go to batch production directly, and then mass production.
The device has a giant battery which takes half of the overall volume of the device. However, due to the very high battery usage, the battery should be replaced every 3 hours while the patient is outside. This process had to be doable by the patient.
Also, the battery should stay in place firmly so it won’t disconnect during mobility.
