| # Problem Many individuals prefer specialized coffee, such as French Press, Aeropress, or pour over. We propose to solve the problem of making this Aeropress coffee to reduce the effort in its preparation. # Solution Overview We propose making an automated Aeropress coffee maker, which will be done via three subsystems: boiling the water, grinding the beans, and extracting the coffee. # Temperature-Controlled Water Boiler Subsystem To extract the coffee we will need hot (or boiling) water. We will create a variable temperature control system that will allow the user to define a temperature between 175 °F and 212 °F using 5-degree increments, using digital logic controlled by a knob and measured using a food-grade digital thermometer. Controls will shut the system off when the temperature reaches a threshold. # Coffee Beans Grinder Subsystem To grind the coffee we will use a motorized hand grinder, which will apply torque at the handle. Prior to usage, the user will insert their desired amount of coffee beans into the grinder, to be ground when the process is started. # Hot Water Extraction Subsystem The coffee grounds and hot water are to be added inside the Aeropress and extracted. This subsystem will have a user-defined press time to help them get their ideal cup of coffee. There will be a pressure sensor. # Criterion for Success Our solution can accurately produce a cup of coffee, which has been heated up and processed for the defined temperature and time. As a reach goal, we will add functionality to produce different sizes of cups or add a voice interface (e.g., Alexa or Google Assistant). While there are many existing coffee machines on the market, our solution will be focused on making high-quality Aeropress coffee. We seek to create a low-cost product that can produce coffee with the desired settings. |
