Building

Currently, there will be 4 parts to our first prototype. The main lid with a ring, the water flow lid, the small cylinder to act as a hinge, and a rubber band.

Main Lid w/ Ring

This part has an overall radius of 32.8 mm and a height of 6.35mm. The most important part is the radius, which will be detrimental to the lid fitting in the cup. Also, the radius of the hinge on the lid must be a little larger than the cylindrical hinge so the cylinder can fit inside. Manufacturing is easy since we are getting it 3D printed, so it doesn’t require a factory manufacturer. The only costs will be the filament for the printer. Since we plan on buying our own reel, we will be able to use the printer as much as we want. Filament reels cost around $20. We will get help from the Westwood Robotics Team and Rushil Patange.

We will easily have enough material if we buy a reel, and it is easily accessible. For the first prototype of this part, we will only be using one material for simplicity.

Water Flow Lid

The lid has two antennas which will latch onto the hinge on the main lid. The antenne are 3.13mm apart with a hole with radius 0.889 mm. The hole is the most important part as if it is too small, our cylinder will not fit. Manufacturing is easy since we are getting it 3D printed, so it doesn’t require a factory manufacturer. The only costs will be the filament for the printer. Since we plan on buying our own reel, we will be able to use the printer as much as we want. Filament reels cost around $20.

Cylinder Hinge

This part has an overall height of 10.16 mm and a radius of 1.73 mm. The most important part is the radius, which will be detrimental to the cylinder fitting in the cup. Also, the radius of the hinge on the lid must be a little larger than the cylindrical hinge so the cylinder can fit inside.

*NOTE: We may replace this with a paperclip for our first prototype to reduce costs.

Rubber Band

We know what a rubber band is. We will be using it to create extra friction between the cup wall and the cup, so the lid does not fall into the drink. The problem wil

Rough Sketches:

*In the indent for stainer, we might hot glue a strainer in it, but we have not yet decided on whether or not we were going to do that

Build Plan

-Tools

-3D printer, computer/inventor

-Materials

-3D printer filament, red solo cups, overflow bevel, strainer.

-Safety procedures for build

-WE WILL NOT BE USING REAL DRUGS!

-For our build our product will be 3D printed. We will not touch the hot plastic until it has cooled for at least 30 minutes.

-Build procedure

-For the team's design we have constructed a model of our product on CAD with real world dimensions. So we could then use the design to be 3D printed and have a demo of product ready to be tested.

-After printing, the prototype had to be constructed.

-We took a strainer mesh and cut a segment off to fit into the indent of the main lid.

-The mesh was very hard to cut so we used a drill to perforate it, and then used wire cutters to finish the job.

After making the design modifications from above, we made the flap larger and the lid larger to sit higher up on the cup. The buulding of our 2nd and 3rd prototype is shown below:
