EDSGN 100 Introduction to Engineering Design Sec. 010 Team: 6 Abstract:

The design for a dumpling maker came through the process of conceptualizing

various designs based on criteria and preferences by the design specifications and

prospective customers. The final design is a compact, self-contained, easy to use, semi-

automatic machine that uses different compartments to separate ingredients and put

together dumplings from a system of rollers and gravity. The rollers are operated by a

hand crank and belts that connect them for ease of use. It shows the basis of a

functioning dumpling maker that can be used in personal or professional settings.

EDSGN 100 Introduction to Engineering Design Sec. 010 Team: 6 Introduction:

The design process, conceptualization, and details of the dumpling maker are detailed in

this report to reveal thought processes, decisions, and final design for this project.

Problem Statement:

Making Dumplings by hand is too inefficient for mass production.

Mission Statement:

Our goal is to create a more efficient and cost-effective method of producing dumplings.

Design Specifications:

The dumpling maker must be automatic or semi-automatic, safe, easy to maintain,

dishwasher safe, able to make at least ten dumplings per minute, and cost no more than

two hundred dollars.

Gantt Chart:

FIG. 2.

Customer Needs Assessment:

Prospective customers of a dumpling maker desired a machine that is compact, easy to

use, and self-contained. We formulated the basis of our design off of the design

specifications and these preferences.

FIG.1.

EDSGN 100 Introduction to Engineering Design Sec. 010 Team: 6 Design Features:

This design includes a box style setting where the top is indented to allow the

separation of the dough and filling compartments. Both the dough and filling are fed

through by rollers connected by belts and a hand crank to operate. Platforms are located

inside to guide dough to a second set of rollers and out of the machine through a cut hole

in the front.

Operation Instructions:

To operate the dumpling maker, put filling ingredients into the middle section that

is cut off from the rest of the top of the maker and mix together dough ingredients into

the general section of the top. Rollers and holes are located close enough together that

dough and filling will not go through until fed by operating the hand crank. Turn the

hand crank clockwise to turn the rollers and begin feeding dough and filling into the

machine and eventually out of the machine cut into dumplings along with some excess

dough that can be reused in top section for further dumpling creation. Speed of process is

based the speed on which the hand crank is turned but should not exceed twenty

revolutions per minute for best results of dumplings.

Working Mechanism:

The design works through a system of rollers and gravity. When the dough and

filling are in their top compartments, the hand crank will feed them through to center of

the dumpling maker. The dough is fed as two separate strips which land on a slanted

ramp that directs each strip to the center while the filling roller, which have semi-circle

cut in them will allow a portioned amount drop onto the dough per revolution. When the

dough strips and filling meet, they are entering a second set of rollers which have a

dumpling shape imprinted into them with metal edges to cut out a dumpling with each

revolution of the hand crank. The finished dumpling and a small amount of excess dough

travel down a final ramp which will drop it out the front of the dumpling maker.

Cost Analysis: Total estimated cost: $103.17

Aluminum Panels that will be cut and shaped to be used to form the basic shape of the machine and several ramps on the internal to help the machine function more efficiently

$9.88 per panel, 5 Panels

The crank plus gears will allow the machine to go through the process of flattening and cutting the dumpling into shape

23.99 for the Crank plus belt

Aluminum Rods or rollers will be used to flatten the dough

2 1/2x36 inch rods will be cut to size, $7.21 each

Nuts and bolts will be used to hold the various aluminum plates and rollers together

20 Nuts and Bolts, $10.96

Washers will be used with the nuts and bolts to allow them to have a more flush fit to the aluminum

25 pack, $4.50

EDSGN 100 Introduction to Engineering Design Sec. 010 Team: 6 Conclusion and Suggestions:

This design is the basis for a dumpling maker that is a much more efficient way to

create dumplings by hand and is a good tool for anyone that wants to make them for

either personal or professional use. Some suggestions on improving the design include

removing wasted space to make the design more compact and cost effective, making the

final hole bigger to assure that the dumplings fit out after they have been created, and use

gears instead of a belt to connect the various rollers to improve speed of the dumpling

maker.
