2th Semester

In the 4th Semester I worked together with two students from South Korea and Canada. It was created in the course Invention Design, where we had the possibility to create a dystopian scenario for our product.

This project is a possible vision of the future in the year 2050. Pollution is getting worse and worse, and the human body now takes damage simply from being outside, as a result of intense air pollution, climate degradation, and severe UV light. Human wealth is focused on solving surface level problems as a result of climate catastrophes instead of the root problem. People try to ignore their surroundings and attempt to live in blissful ignorance. This project is a reflection of that ignorance, and its purpose is to provoke people to think about their behavior and the future they are creating.

Our project revealed a future product that can be used to clean your lungs, eyes and skin. It is an everyday product and is used every day like a toothbrush

It consists out of the following:

    • Main Device

    • Three attachments, that can be put on the main Device

    • Dock, that is used for charging and refilling

The main device has a dip to put the attachements in and 3 LED lights to show current battery status. Only one button is needed to start and stop the cleaning process. 

A speaker gives notification sounds. In the bottom right image our attachments can be seen in more detail, and are 5cm by 5cm. The left one is for the lungs, it’s shape is meant to be comfortable in the user’s mouth and has holes for inhaling. The middle one is for skin, with an accordian shape for easy manoeuvrability across different parts of the body, and features a laser and holes for spray. The right one is for the eyes, it forces your eyes open during the cleaning process.

The eye-attachment works as follow:

Hold the attachment up to your eye and press the start

button. The expansion ring moves your eyelids apart, and

the pressure gauge reaches out and touches your eye to

measure and collect data. Then your eye is smoothed to

prevent conjunctivitis. You will feel a slight scratching on

the surface of your eyes during this part. A UV light

protective spray is applied, and once you hear the beep,

you may remove the device.

The lung-attachment works as follow:

Put the attachment in your mouth and press the start

button to start the cleaning process. You inhale once,

deeply, through your mouth so that the nano-rope can

begin descending and dividing into your alveoli. While

the device removes any unhealthy substances and

sprays an adhesive spray to make the next cleaning

easier, you must breath calmy during the whole process.

Once it is done, it will start to remove itself from your

lungs automatically. Once you hear the beep, you may

remove the device.

The skin-attachment works as follow:

Press start button to begin, and run the device over your

skin. If the device has found a part of your skin that

requires attention, the voice interface will tell you to hold

the device still in that region and press the start button.

The attachment will then begin with tissu

nanotransfection. Ignore the pain as much as possible. A

healing spray is applied to the wound to help it recover.

Once you are satisfied, you may press the button to end

the process.

Here you see the Dock.

The dock is the base for the main device and its

attachments when they are not in use. It charges

the main device and cleans and refills the

attachments. From time to time you have to

manually refill and clean out the drawer at the

front of the dock.

To make the final prototype work, we used an Arduino with a few other components. The main device has a speaker for sound and a LED charging signals, both of which are connected and controlled by the onboard Arduino.

To enable the sound from the speaker, a SD card was required, as it sends the sound files to the speaker.

The LED is simply connected to the arduino, and is turned on all the time when the device is active. A magnet is also built inside underneath the dip, in order to connect the attachments to it. As a result the attachments also feature a magnet inside of them.

To make the dock realistic, we used 3 LED rings (each one with 24 individual LEDs), and another Arduino to control the simulation of the organ health percentage. This percentage can be changed via remote control, which sends a message from a device we control to an IRreceiver that is connected to the Arduino in the dock. We decided to add this feature to enhance our exhibition by making it more realistic and more of a spectacle.

Since the 3D models we used to make the renders were made in Rhino, it was very easy to export them into 3D printing files. We used the Ultimaker 2+ and 3 to print our models in white. We then proceeded to refine them by sanding all the parts and spraying them with white paint. The top part was painted with a glossy spraypaint to make it look more elegant and hygienic.

Following the final storyboard we made, we started filming the video at our university with the help of a professional by the name of Max Walter. We began by filming still shots of the product for b-roll, then the product being used by one of our group members, and finally the interview style shots of another group member. We were very happy with

the footage we received as it was all high quality and consistent in its style.

To show the user how the product truly works, in

detail, we printed a manual that shows the steps

involved in using the product and everything

that isn’t communicated with our advertisement.

The manual is illustrated for added visual

reference, and written in German, English and

Chinese. We felt that a manual was the perfect

addition for our exhibition.
