Final Project Proposal

Project Ideation

1- Tell us about the purpose of your project. Which problem does it solve? Why do you care about this? What were you inspired by? Include images and videos of similar projects


As type 1 Diabetic insulin plays important role in my daily life and if I forgot to take the dosage the result will be very bad.

This issue affect millions of people since the number of people living with T1 raising rapidly.

I saw a device few years ago attached to insulin pen and it do very simple job, tells you when was the last time you took insulin so if you have any doubt whether you took your dosage or not the device will till you.

2- Describe the project idea and general features. How would it work?

My project idea is very simple when I press the pen button to take the insulin the counter will start to count and then rest and start again when I take new dosage. Typical it should contain LCD and sensor to detect when the button is pressed.

After doing low fidelity prototype and discussion with my instructors I decided to change the idea a little bit and instead of creating something that attaches to the insulin pen I decided to create a box and I can put the 2 insulin pens I use.

The screen will show 2 timers one for every pen.

3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop

Project Planning

4- Describe the Technical Modules that your project consists of

Construction Parts

My project will be designed as 3D object using Fusion 360 and fabricated using Pursa 3D printing machine.

Input

(Sensing, Tactile Input, and/or Graphical Input)

My device will use pressure sensor / Hall effect sensor/ push button.

Action

(Physical and/or Graphic)

The action on my project will be text action LCD screen showing time count

Brain

In order to get my project work I will use Arduino uno.

Power Management

My power source will be battery

5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.

6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.

  • Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration

  • Complete Features: are the set of features that will complete your original project objective and vision

  • Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish

Minimum User Features

  • Showing time passed since last time the insulin was taken:

    • Action: Showing time

    • Sensing: Pressure

    • User Input: None

  • Showing temperature inside the box since the insulin pen should be kept in specific temperature.

    • Action: Measuring and showing temperature on LCD screen

    • Sensing: Temperature.

    • User Input: None.

Complete User Features

  • Above temperature warning:

    • Action: Alarm if the temperature went above 30 degrees.

    • Sensing: None

    • User Input: None

Nice-to-have User Features

  • Mobile app connected to the device to see the data since the mobile is the most used device in our life nowadays

    • Action: Programmed mobile app and Bluetooth to send data to mobile app

    • Sensing: None

    • User Input: None

7- What are the project tasks and its time-frame?
