The idea

Within the core elective From Idea to Design there were multiple options for certain directions. The direction of ‘Health’ was favored by the group. Besides multiple challenges, the direction of Health gave enough inspiration for opportunistic ideas. The challenge in choosing Health was in finding a problem where we, as starting designers, could develop a realistic and approachable product. The problem of UV-radiation, which is harmful to the human body, was being chosen as a challenge to work with. The leading question was: how do we get people to use enough sunscreen? This because nearly 30% of the people does not use the proper amount of sunscreen on a daily basis. For this problem, a smart bottle named noxxi was developed. noxxi makes the applying of sunscreen more easy and user friendly. Besides that, noxxi shows the user the proper amount of sunscreen required for each 2 hours spend in the sun. This report describes how the concept of noxxi is developed and which decisions were taken to come to the final concept.

The design

Firstly, the modular wristband included with the noxxi bottle contains a photochromic pigment. This means that when the pigment is exposed to UV radiation (and thus sunlight), the pigment changes its color. In the prototype, the photochromic material is implemented in a silicon wristband. While this works, it is not ideal to include a wristband based on silicon in the final product. Because the goal is to apply sunscreen to both your skin and the wristband, where the wristband indicates it is time to reapply when it changes color, it would be better to use a material that reacts to water and sunscreen in the same way human skin does. An example would be to incorporate the pigment in a leather wristband, to simulate skin.
The second piece of specialized technology in noxxi, is the sunscreen reservoir. This reservoir is contained in the cap on top of the bottle. The user fills up the reservoir by squeezing the bottle. Once full, the reservoir contains 35 ml of sunscreen, exactly enough for one average human body according to the World Health Organisation. This reservoir is then emptied by using the spray cap. This system is functional, but not ideal. Since human bodies differ a lot in size and surface area of the skin, the final design could use one of the following concepts to solve this: have multiple sizes of caps available or an adjustable cap.
