This project was made as a continuation of the preparation project. The cup that was developed on the previous project would only record the EC, however the information was not displayed. Furthermore, the use case for the system currently support salt measurements, but it can be extended, to measure other food additives through urine samples, mainly sugars and fats. Considering that there are no user-friendly devices to measure in urine samples, a design has been proposed. The system is composed by a visualization device and a measuring cup that measure salt. Based on the performed usability tests, a design recommendation has been made for future research on how the sensors can be extended to measure glucose and pH and to make the design of the cup robust, for future usability tests.
During the FMP I programmed a system that can measure and display salt levels and can be expanded in future iterations to measure other parameters. I learned about new types of sensors that can read glucose and pH levels that could be researched in future iterations. Furthermore, I learned about the science behind these sensors and learned about some limitations of the technology. For instance, that the glucose sensor would need to be recalibrated after a certain period of use.
I looked at the societal impact that chronic diseases have and learned about how dietary behaviors can increase the incidence in contracting these diseases. I also learned what my role as a designer is and that I can have influence on the problem and people’s behavior through design. I developed a new usability test setup considering the system would be tested in the field and it would happen remotely. Next to that, I did interviews with target users to learn from their experience, empathize and create a patient journey through the development of a chronic disease.
Technology and Realization
Based on the research of sensors, I made a design recommendation to extend the capabilities of the sensor. I also fabricated the device that would communicate and store the time and measurements from the cup. Additionally, I programmed a demo of the panel with multiple readings for visualization purposes. I also made a cost analysis of the design.
Business and Entrepreneurship
At the start of this project I looked for companies to collaborate to develop the cup. I searched for current market products and saw if there are possible competitors for my design. During the retake I learned what the role of MVPs are and how they are used throughout the development of new products. During the retake I evaluated how my design does not fit an MVP criterion, but explained how the proof of concept can be researched further to reach an MVP status.
Creativity and Aesthetics
I improved the quality of the report by making it visually appealing. I made sketches during the ideation phase of the feedback device and the visualization of the concept was adapted to include the whole system. I improved the quality of my work in terms of the design of my report and house style. Through the retake, I improved the design of my online portfolio and included more visuals that show my deliverables.
Design Research Process
Through this project I learned about the complexity of designing medical products. There are multiple considerations that need to be made from an ethical and legal perspective.
