Introduction The purpose of this project was to design an efficient dumpling maker which

satisfies all of the set design specifications. The project was delegated to the team by the professor of Engineering Design 100 Section 202, Xinli Wu.

A mass survey was taken to document the needs of consumers. Ideas were developed based on the customer assessment survey poll and design specifications. Design matrices were utilized to select the best design of the generated concepts, which was then drawn in Solidworks and constructed. This entire process spanned over two weeks.

Finally, the entire research and design process was documented in this final design report.

Description of Design Task Problem Statement: Dumplings are a very popular food at some restaurants, but they require a lot of skill and time to make.

Mission Statement: A dumpling maker needs to be designed to fulfill the design specifications as listed below, while being faster, more efficient, and at a lower price point than a potential competing dumpling maker.

Design Specifications:

The dumpling maker should be automatic or semiautomatic. The dumpling maker must be usable in restaurants or homes. The dumpling maker should produce at least ten dumplings per minute. The material cost for the dumpling maker should not exceed $200 unless it can be

justified. The dumpling maker should be safe, easy to maintain, easy to use, and dishwasher

safe.

Customer Needs Assessment Sample Survey

A survey was conducted to gain insight on the qualities a dumpling maker should have based on popular opinions of people, who actually eat and make dumplings as well as use a dumpling maker machine. The most popular answers are documented below.

Dumpling Maker Satisfaction Survey

1. Have you ever had dumplings? If so, how often do you have them?

Twice a week; once every few months.

2. Have you ever made dumplings?

Yes

3. What would you be willing to pay for a dumpling maker?

$25

4. What size would you prefer your dumpling maker to be?

Size of a microwave

5. How quickly should the dumpling maker produce a serving of dumplings? How many should it produce?

10 seconds per dumpling

6. Would you rather the maker be constructed of plastic or metal?

No preference

7. Would you rather pre­make the dough or have the dumpling maker mix the dough?

Pre­make

8. Would you want to be able to change the shape of the dumpling? If so, which other shapes?

No

9. Would you like your dumpling maker machine to be semi­automatic or automatic?

Semi­automatic

Engineering Analysis Working Mechanism

From the responses gained through the survey, this semi­automatic, single mold, plastic and metal household sized dumpling maker was created. The simple hand­crank controlled the rolling of the rollers, the filling of the dough after it would slide onto the dumpling mold, and the folding of the mold. The dough and filling must be premixed before being put into the dough and filling holders for the dumplings to be made. The rollers have a circle indented into them and they are made out of metal so it cuts the dough as it is rolled through. A minimum of 10 dumplings will be made per minute.

Summary and Conclusion Based on the customer needs assessment and the design specifications, Team 6

successfully designed and prototyped the Wu­3000.

Most of the team put in extra after class hours in order to guarantee quality in our design. The survey helped to gain insight on the necessary qualities of a dumpling maker. The Team adhered to the Gantt Chart ensure product delivery time. Through careful design conception, possible issues were consulted, which resulted in minimal problems in the prototyping stage.

The final project helped the team develop useful knowledge and experience as future engineers.
