This past week was reading week which meant there was no class activities. This allowed us to concentrate on developing the prototype and the mobile app. Keep reading to see our progress! Mechanical DesignThe sleeve (in blue) has been redesigned as shown below. The sensors such as the orifice plate, the differential pressure sensor and the LEDs have also been modeled and included. The black parts represent the locations for the circuit boards. MarketingThe "R" on the logo has been updated. The finalized logo can be seen below. Mobile App DevelopmentThe Room database has been set up. In addition, the UI for the Device Summary screen has been completed. Last week, the screen was not scrollable. After some debugging, the issue was determined to be in the onMeasure function that was used to determine the size of each of the columns of circles and fixed. The screen is now scrollable. The next step is to link the fragment to the previous fragment such that when the user selects a device from the Device Home screen, it will open the Device Summary screen. In addition, the data on the screen is currently hardcoded and will need to be updated to reflect the data that is pulled from the inhaler attachment.
Mechanical DesignThe orifice plate has been printed by a resin printer. A resin printer is used instead of a 3D printer because it can achieve higher resolutions. The orifice plate is small and has several fine details. The printed orifice plate is shown below. MarketingFurther development of the logo. Stay tuned for minor changes as the R tries to look less derpy.
Mechanical DesignThe 3D design for the orifice plate is completed and ready to be printed! The dimensions for the plate were based off of calculations to detect inhalation rates from 0 - 100 L/min. The cross-sectional view and drawing are included:
