Brainstorming

Idea One：Food cutter

Idea Two：Wine Shaker

Idea Three：Dumplings Maker

Problems that we need to solve

Step1: How to make a dumplings skin？

Because there are many kinds of dough-making machines on the market, the general mechanical principle is to press the dough of corresponding size into dough by extrusion, and then use some cutting dies to cut out the standard dumpling dough size and shape. The size and thickness of the dough are actually more important here.

Step2: How to mix the dumpling fillings？

Stirring dumpling fillings can be completed with a conventional rotary machine. The most basic requirement for this part is to rotate, stir and divide the same amount of dumpling fillings into the dumplings.

Step3: How to squeeze the dumpling fillings and make a dumpling？

There are usually many ways to make dumplings, and different dumplings can be made into many different shapes. The main thing here is to break down the action of pinching dumplings. The first step is to fill the dumpling dough with dumpling filling. In the second step, you need to find the creases for pinching the dumpling dough; in the third step, you need to adjust the appropriate strength to pinch the dumplings.

Step4: How to transfer and place the dumplings？

The last step requires a transport mechanism to transport and place the dumplings

When we find that there are so many steps that need to be broken down, we feel that there is not much time left for us.
