In this design project, the team and I came up with a fully automatic dumpling maker, which not only is compact in size but also extremely fast at the process. It is easy to clean and aesthetically pleasing to the eye. Here are some details about my innovative dumpling maker.

Design Features:

The entire machine runs on a programmed system such that every task is performed at specific intervals. Minute details such as the speed of the conveyor belt have been taken into consideration so that all parts and processes work together in order to produce a dumpling.

As soon as the machine is switched on, the slicer is programmed to come down at a time period after the machine has been started. Hence, all the user has to do is to place the dough and start the machine. The smasher also works in the same manner as it is also programmed to drop down at a certain time after the machine is switched on. The speed of the conveyor belt has to be altered in order to flatten every sliced piece.

In the filling stage, the filler will automatically drop same amount of filling for every dumpling. By placing the filler above the clamper, after it drops the filling, the

clamper will be triggered and seal the dumpling. The clamper then rotates on a rod placed beneath it and releases the dumpling on the other conveyor belt. For more details on this project, kindly check out the entire report here.

The goal of this project was to design a system which eliminates the pollution of waterbodies caused by storm water running off agricultural fields. This report illustrates the design process the team used to create a system capable of not only mitigating this pollution, but also saving the environment and money. The teams’ mission statement was very much related to the problem and aimed at improving the environment.

Mission Statement: To design a system which collects, filters, and purifies contaminated water caused by agricultural runoff and efficiently reuses the water collected. Here is a visual representation of our efficient design:

3-D Printing Project

Project Description: In this project, we were supposed to come up with a design for any object that could be 3-D printed. The object could either be an existing product or something innovative. I chose to design a phone cover for the Samsung Galaxy S9 as it is simple to print yet involves many innovative features. Here are a few pictures and drawing of my phone cover.

Design features:

This phone cover is meant to take any type of damage. Every single day, thousands of people across the world drop their smartphones which causes damage to it. People neither want a cover which is too bulky and makes their phone heavy. They need something sleek and one which can withstand daily drops. This phone cover does a great job doing that and is highly durable. The 3D printed model is made to scale for a Samsung Galaxy S9.

Another key feature is the gripper attached within the cover on the back. This helps people comfortable hold their smartphone and also acts as a stand, whenever they want to place their phone on the table.

For this project, my main focus was that the entertainment center would easily be assembled and shipped by the consumer. Hence, I designed each and every part in a manner that it would simplify the consumers experience while assembling this unit. Here is a visual representation of my entertainment center.

Design Features:

This entertainment center design fulfils all the requirements for the project as it provides several compartments for storage along with the necessary electronic devices for a home theatre system. It is also aesthetically pleasing to the eye.

For the assembly method, I focused more simply sliding the parts into the designated places instead of screwing them. However in key positions, screws have to be placed in order to maintain sturdily.

Conclusion and Acknowledgement Being passionate about design, EDSGN 100 is a course which has not only enhanced my knowledge on this subject, but also helped me find my creative side. A huge part of my learning from this course goes to Professor Xinli Wu, who is not only a great teacher but also a person I admire. The assignments and the projects provided by him were sufficient to test my design skills. I would also like to TA Jack Kairys for having helped me in several moments throughout this course.
