Ayxon-Dynamics turned to Pilotfish for a compact and user-friendly design of the Coloryzer®. Along with the design, Pilotfish is also responsible for mechanical engineering, packaging and production of the product.
Pilotfish designed an approachable device where the interaction surface faces the user. 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.
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.
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, when 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, as well as ensuring the door blocked light sufficiently. To avoid scratch marks from the sliding, POM material was used for the underside of the door.
The product DNA phase is where we define all the overall feeling of the product and define all the necessary requirements. As well with the basic setup of parts and working principle. The end result is the initial release of the PD document.
Proof of Concept
In the POC phase, we develop the working principles and test them. All critical and unknown aspects of the product have to be understood and problems must be solved before moving onto the next phase.
ID & UX Design
During the ID phase, we create the product’s appearance and user interaction. We not only make sure that the product is designed to be ergonomically friendly and visually appealing but also keep the production feasibility and cost needs in mind. By working hand in hand with engineers and production managers, we design the product to minimize the risks and costs that may occur during the production
Our team of engineers designs the encasement and all details for production, including draft angles, screw bosses and ribs for assembly. The engineering work is tested with working prototypes and the final deliverables are 3D files and supporting documents ready to start tooling. Pilotfish also takes care the development of the electronics with the support of our team in Taiwan.
The Coloryzer® works with all reagents available in the market, is easy to use, accurate and affordable. It is connected to an app which provides feedback on the device’s status and results of the measurement. The product is expected to be launched on the market in the second half of 2021.
The Mechanical Engineering and Packaging phases are currently in progress. Pilotfish is also working on the carry case that comes with the device and which will make it easy to bring the device out to the field. This protective case contains everything you need for a measurement.
