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.

Challenges

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.

Jaras Medical Company, after R&D different therapy methods for cancer, concluded a therapy method that uses alternative electrical fields to treat cancer tumors locally. After this, they were after an optimal design for their device’s body that has a good user experience using the user-centered design (UCD) approach.

Due to the minimum therapy period length being six months, for each user, comfort, lightness, portability, and having a replaceable was our priority in the design.

We tried it to look friendly as much as being serious and modern.

And this is the concluded form that we designed. For the material we used aluminum for its lightness and heat sync factor. It’s production method is also aluminum extrusion which lowers the end price of the product.

 A replaceable battery that can be attached from either side with a magnetic end on each body.

Multiple electrodes are attached to the device with wires, and the electrodes itself are attached to the body part that requires therapy. After that the field therapy process takes place.

. On the Chest

The device is made to be set on the patient’s body. The patient has to carry it around all day. 

. On The Head

The central part gets on the chest and back of the patient, and the electrodes go around the head. 

. On Abdominals

It should be all ergonomic so it won’t tire the patient.

. How It Work

The TTfields take place on both sides of tumor and start by affecting them all the time with magnetic fields. As the time goes, the tumor starts reducing in size and finally gets eliminated. This is a new technology yet proven and has passed multiple tests.

_ Light and Compact

Ergonomics was one of our main priorities while starting this project. Because of the high level of human interaction this device has, it had to be as comfortable as possible for the user. Also, the unisex and slim design makes the bag adequate for all genders and looks. The user can wear coats, windbreakers, etc. while having the device on them. The lightness of the used materials helps the user become unaware of wearing the device after a while. The only time the user has to remove the device during the day is while changing clothes, which is a significant factor in helping the patient get used to the TTField.

One of the most complex jobs for us was to fit all the parts into one compact device. All parts should be kept separately. And most important of all, since we had a water container in it, we had to make sure it’s perfectly sealed, so no humidity gets to the board.

The most compact non-invasive Ventilator you’ve ever seen. It can be put on a table near your bed or the ground. It’s balanced and heavy enough you won’t have to worry about it falling.
