hey guys welcome back again to my Blog. I have sad news as this blog will be the final blog for this module 😕😕😕😕. Anyways, today...
In this page, I will:
1. Breifly describe my team chemical device
2. Show how the team planned, allocated the tasks and executed the project.
3. Document the entire design and build process of the chemical device and include videos, pictures and screen captures of the processes.
4. Include "Hero shot of every milestone of the processes, example the part A that was 3D printed, part B that was laser-cut, electronics components moved/worked according to the program. Hero-shot is taken with the person-incharge holding/working/making the parts.
5. Include the name of the person who was in-charge of every part of the project.
6. Document m yindividual contribution to this project.
7. Provide the link to the page of the blog of my teammates.
8. Describe the problems encountered and how the team solved them.
9. Include all the project design files as downloadables files.
10. Mebed the final prototype design file, i.e., the final fusion360 deisng file showing the entire prototype.
11. Type my Learning reflection on the overall project development.
1. Our team Chemical Device
- In this section, I will briefly describe my team chemical device.
Tea brewing is highly dependent on the temperature and the brewing time. Man tea drinkers want to have their tea brewed at a certain temperature and time to achieve the best taste. This brewing process can be a hassle.
Therefore my team have decided to design and build a prototype of an automatic tea brewer that can brew tea at a specific range of temperature and brewing duration. This will save the user time in the long run as the chemical device can be set to the preference of the user in terms of time and brewing duration.
- Below is the hand sketch of the chemical device.
Initial hand sketch of the chemical device:

2. Team Planning, allocation, and execution
- In this section, I will list down my team member's name and their respective roles (CEO, CFO, COO, CSO)
- I will show the finalized BOM (BILL OF MATERIALS) table.
- I will show the finalized Gantt chart (planned and actual) and the tasks allocation for each team member
3. Design and Build Process
In this section, I will provide documentation of the deisgn and build process.
Part 1. Design and Build of Pitcher Jug (done by Joel).
Part 2. Design and Build of Lid (done by Jing Hui & Me).
1. This was the intial design of the lbottom of the lid we wanted to print:
This print ended up taking an estimate of 13 hours.... ridiculous we started our print at 8am and by the time the lab was going to close it wasnt even done😱😱. Yeap then we decided to change it to our final design:
Hero shot of the bottom lid print:
2. Extension for motor:
Hero shot of the extension for motor:
The extension we printed it the yellow coloured thick stick
3. Cylinder for ball infuser
Hero shot of the cylinder for the ball infuser:
Part 3. Design and Build of Body (done by Joel, Jing Hui & Me).
Design and build of the body:
Here are some pictures of us in action yay.
Part 4. Programming of motor and Icd (done by Jing Hui).
Part 5. Integration of all parts and electronics (done by Joel, Jing Hui & Me).
First drill a hole into the printed extension so the chain can be passed through:
Next connect the strainer to the motor and place it above the cylinder:
Hide the arduino board inside the top lid:
Combining all together we get thisssssss:
4. Problems and solutions
In this section I will describe the problems encountered in the design and build process and how the team solved them.
5. Project Design Files as downloadable files
In this section, I will provide all the design files (Fusion360 files,. dxf files,, stl files, arduino programs files) as downloadable files.
Everything is complied in a google drive:

6. Below is my Learning Reflection on the overall Project Development.
After completing this project, I want to talk about a few points I have noticed.
Communication issues:
I felt that my team did not have the best communication throughtout some parts of the project. For instance we had a small miscommunication the day before the day of the presentation which might have lead to the chemistry of the group to be messed up and we did not do as well for the presentation as we have expected.
Group member not cooperating:
My team consisted of 4 members, however one of my teammate was missing throughout the entire project. I am not going to be dropping names but he/she did not show up for any of the meetings in school or online apart from probably 1 or 2 which made our team a little disappointed in her.
Draining:
As this project was a extremely long which took place over almost 3-4 months, it was a little draining for us as my team had trouble completing some of the parts of the project for instance TRIZ. TRIZ was foreign to us and it took us quite awhile to understand how to use the table and finding the right parameter was hard too. Apart from the countless nights we had to stay up to complete the report and braining of the tea maker machine design we wanted to design we also had to wake up early to head down to the W314 Lab to 3D print our design even on days we did not have any lessons. We had to meet at W314 at as early as 8am to chope the 3D printer if not it would have been occupied by other batch mates who wants to use it too. What is even tougher is that two of the 3D machine was faulty and there were only 4 left. Moreoever, as a single print could take hours to complete if we did not manage to get the 3D printer at 8am we might have to wait till around lunch time 12noon before we could use after someone had completed their print.
Experience working with teammates:
In spite of all the misunderstandings and the mishaps that happen throughout this project, I still feel that I had fun working with my teammates and I would like to thank them for making my CPDD module less boring ✊✊
