Keep your water in focus

Test water on site 

The Coloryzer® helps people accurately test water conditions, covering a wide range of users from the hobbyist, such as aquarium and swimming pool owners, to the professional, such as coral growers, breeders, and laboratory institutes. The device uses light-sensing technology to analyse the quality of water.

Proof of Concept

The task

Ayxon-Dynamics turned to Pilotfish for a compact and user-friendly design of the Coloryzer®, to optimise the unique light-sensing technology for accurate, fast and portable water analysis. 

The solution

Pilotfish designed an approachable device where the interaction surface faces the user, and the device encapsulates the water samples in complete darkness for accurate analysis.  

This design was inspired by a mountain peak, its tapered form giving it a robust and stable stance. The slanted surfaces support the directionality and gesture of inserting the cuvette, which has to be placed in the device at a certain angle for optimal measurement.

Magnetic sliding door


Due to the darkness requirements of the sensor, the cuvette needs to be fully covered during the measurement. To sense this, Ayxon-Dynamics provided a hall sensor on the electronics that sensed the device was closed by contact with a magnet, which then signaled to start the reading of a sample. This opened up the opportunity for a unique opening and closing mechanism for the device.

 

Taking advantage of the use of magnets, Pilotfish designed a magnetic sliding door that held securely in place in either open or closed state, allowing for a simple, yet satisfying one-handed interaction. The magnetic attachment also allowed for easy removal and cleaning, which was an important factor for the device.

 

In the POC phase, the size, strength and placement of magnets were tested for optimal sliding and holding results and to ensure the door blocked light sufficiently. To avoid scratch marks from the sliding, POM material was used for the underside of the door.

The Coloryzer® uses light sensing technology, where an LED beams light through a water sample held in a cuvette. The beam is received on the other side of the cuvette by a sensor and analysed.

For accurate results, this technology requires absolute darkness inside the device. This was an important aspect to consider in the design. In the POC phase, Pilotfish tested the effect of surrounding light on the sensitivity of the sensor, and found a simple solution to block all incoming light by creating a tube that covers the sensor area.

Connected, portable water analysis

The Coloryzer® works with all available reagents and is easy to use, accurate and affordable. It is connected to an app that provides feedback on the device’s status and results of the measurement.

Pilotfish also designed the carry case to hold all the necessary equipment for measurement out in the field.
