Abstract
A dumpling maker is going to be produced so restaurants can keep
up with customer demand. When dumplings are made by hand, it is
extremely time consuming, and the dumplings lack consistency in their
folding, amount of filling, and size. The dumpling maker produced makes it
less time consuming to produce a dumpling, and the dumplings produced
are uniform. Team five was successfully able to produce a functioning
dumpling maker to meet the design specifications.

Introduction
A dumpling maker will be produced within a two week period while
utilizing the design process. The project was designed to be dishwasher
safe and easy to clean, while also being compact to allow for easy storage.
The dumpling maker must produce at least ten dumplings a minute. The
product must also be safe and easy to use by the consumer. Through the
brainstorming process, many potential ideas were created that were put in
two design matrices to create the best design.
Description of the Design Task
Problem Statement
One of the most popular foods in the eastern part of Asia is the
dumpling. Because if its popularity, restaurants have a hard time keeping
up with the demand for this product. It is an extremely time consuming and
difficult to produce dumplings, and restaurants fall behind and have a hard
time meeting the customers’ requests for the product.
Mission Statement
In order to help restaurants keep up with customer demand, a
dumpling maker will be produced. The dumpling maker will produce
dumplings faster and more efficient than making them by hand. It will
improve the consistency of the dumplings produced. The machine will to
mix the dough, cut the dough, add the filling, and fold each dumpling in a
uniform way.
Design Specification
The dumpling maker will be able to be operated in an automatic, or a
semi-automatic way
The dumpling maker must produce an average of at least ten
dumplings a minute
Unless justified by the designers, the cost of materials for the
dumpling maker must not exceed $200
The dumpling makers must be safe to use, safe to properly handle
food, easy to maintain, fold the dumplings properly, and dishwasher
safe
Design Approach
Project management – Gantt chart
Customer Needs Assessment
The customer survey showed that the stores wanted a small
household size mixer that would take up a small amount of room in their
store. The stores were willing to spend $150 dollars on the product. The
survey also revealed that no store was already using a dumpling maker
resulting in all the stores making them by hand.

Answer of Questions
Concept Generation
Seven different concepts were sketched and used in the design
matrices. The group brainstormed the cart ideas together and used two
matrices to narrow down to possible options to the final design.

Design Feature
Operation Instructions
The dumpling maker works with four steps that are all automated to
help the customer. The dough ingredients are placed into the mixer where
the dough will be mixed. The dough is then pushed through the automated
rollers to make the dough thin and even to produce dumpling sheets. The
dough then runs along the conveyor belt where the dough is cut and filled
with the desired filling. Then the dough is pulled into the automated folder,
folding the circles into a uniform dumpling shape. The operator only needs
to turn on the machine and move the dough from the mixer to the rollers,
and the rest of the machine is fully automated.
Engineering Analysis
Working Mechanism
The mixer is electrically powered to fully mix the dough automatically.
The dough is then run through the rollers to give it a thin and even shape.
The rollers are powered by the motor to allow for easy thinning of the
dough. The dough sheet then falls onto a conveyor belt that moves it down
to the cutter-filler combination. The conveyor belt is a rubber sheet
stretched over rollers to move at a constant speed. The cutter is powered
electrically and the time taken to go up and down is precise to allow for a
cut at specific intervals to create a circle of dough. While being cut the filler
open the slide mechanism causing the filling to fall down the tube into the
center of the circle. Combining the cutter with the filler allows for the filling
to be perfectly centered in the dough. The cutter is powered by a
mechanical arm that moves up and down. The dough circles then move to
the folder where they are automatically folded. All automatic elements are
powered by the motor.

Two foot stainless steel pipe - $27.52
10’’ x 18’’ x 0.1’’ steel sheet - $20.56 ($41.12 for two sheets)
12’’ x 42’’ x .25’’ steel sheet - $30.58
6’’ x 6’’ x .25’’ steel - $16.11
Four inch long, four inch diameter steel tube - $12.77
1000 Watt motor - $42.95
Rubber sheet - $6.33
On/off switch - $0.99
Total - $178.37

Summary & Conclusion
The goal of the design was to fulfill the required specifications as well
as the customer’s needs. The customer’s important aspects were the
product being household sized, being automatic, and a cheap cost. The
dumpling maker would cost one hundred and eighty dollars to produce but
when purchasing in wholesale the materials would be much cheaper to get.
This would allow the final product to be one hundred and fifty dollars for the
consumer to purchase. The design is almost completely automatic allowing
for quick production of dumplings with a few manual components to allow
for easy use. The product is able to produce over ten dumplings per minute
due to the large amount of dough that can be processed.
Operation Instructions
The dumpling maker works with four steps that are all automated to
help the customer. The dough ingredients is placed into the mixer which
will mix the dough. Then the dough is pushed through the automated rollers
causing the dough to be thin and even. The dough then runs along the
conveyor belt through the cutter and filler. The dough is cut into a perfect
circle shape while also having the filling placed within it. Then the dough is
pulled into the automated folder folding the circles into the dumpling shape.
The operator only needs to turn on the machine and move the dough from
the mixer to the rollers, everything else is fully automated.
