Final Project Proposal

(CANCELED)

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

My double tape dispenser

The automatic adhesive tape dispenser.

Adhesive tapes are by far one of the most used materials around my workshop. Different types with a wide spectrum of functions makes them very useful. Last year i made this big tape dispenser that holds 2 tapes. Its made of 18mm plywood and natural padauk wood plugs for the screw holes. i used a thin metal saw blade for cutting the tape. I also added a big heavy stone brick inside to prevent it from moving on the workbench while pulling a piece of tape. You can see how i made it on my Instagram account.

My idea is to design and fabricate a machine that automatically dispenses tape.

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

The basic idea is dispensing a certain length of tape. The length can be set and maybe a small screen denoting the set length. It would also be very cool if the machine can cut the tape instead of pulling it on a blade or similar. The YouTube videos below explains my idea and showing examples of a commercial dispenser type and a cardboard DIY type.

Double tape dispenser

Semi-automatic tape dispenser

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

plywood for the machine case.

Input

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

Tactile Inputs: The device takes user input through a physical and graphical elements such as buttons and knobs.

Action

(Physical and/or Graphic)

The device performs a smart physical action where it pulls a specific length of tape and cuts it. It also has a small screen showing the specified length of tape in millimeters.

Brain

An Arduino board would act as the smart device's brain that processes the input and send orders to perform the action.

Power Management

preferably battery-operated for better mobility and the option to connect it to an adapter .

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.

Front and side view of the automatic tape despenser

The internal mechanism of this dispenser depends in multiple rollers and an upside down guillotine style blade for cutting the tape. The design of the mechanism is still under research as its a bit tricky to pull sticky tape via rollers without sticking.

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 to automatically pull the tape and have easy access to change an empty roll and reload the machine.
Complete Features: First is the ability to produce a certain length of tape and eventually cut it by the guillotine style blade. The length of tape needed should be easily customizable via the keypad and a small screen showing the selected length.
Nice-to-have Features: if it can be also operated via batteries, not only 220V adapters to be able to use it wherever you are.
