EDP 6 - Coin Sorter Challenge Design Proposal
Name: Hunter-Robins Mann
Directions - MAKE A COPY OF THIS DOCUMENT As you write up your objectives and specific criteria for the challenge, make sure to keep these important points in mind:
Use detailed technical writing skills (no pronouns)
Include as much detail as needed so that any other person can replicate the process
If possible, include detailed (dimensioned) parts as either engineering drawings and/or 3D images
After Approval (EDP steps 7...)
Any information that is deleted should be highlighted in red and the font should be white.
Changes from construction should be highlighted in yellow.
Changes from the evaluation of testing/retesting should be highlighted in blue.
Objectives:
(Introduce the system and its unique feature(s))
The main system that will be utilized is the hopper circuit. The next system that is utilized is the sorting system. The sorting system only allows coins of a specific size to fall into the next system. The sorting system will have 2 or even 3 paths but will all indefinitely fall into the correct holding containers. The last system is the holding system which is where the divided coins will be stored. The holding containers will be labeled with the intended coin worth and be drawers.
Design Strategy:
(Explain the details of the system (construction methods, materials used, specific components or features, etc. Subsystems to consider discussing in this section are the hopper, sorting, and collection systems.)
The first system of the coin sorter is the hopper system. The hopper system is a circuit held together by wires, heat wraps, and solder. The hopper system is intended to even out the coins and move them along to the next part of the system. The next detail of the system is what I like to call the singler, the singler ensures that no more than one coin goes through at a time. The following detail of the system is the sorting detail. This divides the coins so that only coins of a particular size fall into the next slot. The final part of the system is the holding containers of the coins. They will be drawers of a sort labeled with the intended coin amount. The pieces of cardboard will be cut out with a sort of scalpel, laser cut, or a combination of the two. The components will be mended together by a hot glue gun.
Testing Procedures:
(In this section, discuss how your testing procedures will be organized. What will your first test be? Will you be collecting data on accuracy of each coin used? Coins all together? Will the testing be timed? Make sure to discuss the types of graphs that will be used to display its functionality throughout the testing.)
The first test will be with just the one sorting path, it will be timed to see how much faster I can make my prototype. After testing it the first time, I will check to make sure the sorting system works correctly and divide the coins into the correct holding containers. I will time every test to ensure that I am getting faster results every time. I will likely use either a bar or line graph to show the changes in speed and accuracy of the tests of various prototypes.
Schedule:
(in this section, discuss your schedule construction completion, testing, preliminary work on presentation. Deadline for the presentation is Friday. February 12, 2021)
To remain on schedule with my construction completion, I will follow a rigorous routine. I will design for the first few days and research on ways that the challenge can be completed. Then, I will work on the actual construction and reconstruction of the prototype. Every time a construction is completed, it will be timed. Then as I am working through the challenge I will start my work on my presentation.
