Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available dumpling making machines are too complex and large for home use, and they produce dumplings that lack the unique shape of handmade ones.
Innovation Solution
A simplified and compact dumpling making machine is designed with a separated dumpling wrapper making device and stuffing-bearing device, utilizing rotational motion and integrating an extrusion forming mechanism with a feeding mechanism, featuring a hollow casing, inclined and vertical augers, and pressing edges to create a continuous, cylindrical wrapper and fill it with stuffing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dumpling making machine is designed to produce dumplings with handmade appearance, then the manufacturing precision and complexity increase, but the device becomes too complex and large for home use
Solution Approach 1:
The machine is divided into two independent functional modules: a dumpling wrapper making device and a stuffing-bearing device. The wrapper making device includes a casing, inclined auger, and pressing edges, while the stuffing device includes a vertical auger with stuffing reservoir. This segmentation allows each module to be simple and compact while achieving the overall function of making dumplings with handmade appearance
Solution Approach 2:
The patent inverts the traditional approach by having the wrapper making device as the primary component and the stuffing device as the secondary component. The wrapper is formed first through extrusion and pressing, then the stuffing is filled into the formed wrapper. This inversion simplifies the overall structure compared to traditional machines that attempt to form and stuff simultaneously
2Device complexity
If a dumpling making machine is simplified for home use, then the device complexity and size decrease, but the ability to produce dumplings with varied appearances is reduced
Solution Approach 1:
The pressing edges are designed to be movable rather than fixed, allowing them to adjust their position and pressure during the wrapping process. This dynamic adjustment capability enables the machine to produce dumplings with varied appearances while keeping the overall structure simple and suitable for home use
Solution Approach 2:
The machine allows for parameter changes in the stuffing filling process, such as the amount of stuffing and the filling speed, which can be adjusted to create different dumpling varieties. This provides adaptability without requiring complex structural changes to the machine
3Device complexity
If the wrapper forming process uses a simple extrusion mechanism, then the device complexity decreases, but the wrapper quality and consistency are compromised
Solution Approach 1:
The extrusion and pressing functions are merged into a single integrated process within the casing. The inclined auger performs both extrusion of the dough and pressing against the casing walls to form the wrapper, eliminating the need for separate extrusion and pressing mechanisms while maintaining wrapper quality and thickness consistency

AI summary
A device for processing food with stuffing, including a casing (1), an inclined auger (5), a vertical auger (8), a first pressing edge (9) and a second pressing edge (10). This invention provides three mechanisms, including an extrusion forming mechanism, a feeding mechanism and a pressing-breaking mechanism. The casing and the inclined auger together form the extrusion forming mechanism which produces a continuous tubular wrapper through a gap (19). An inner cavity of the inclined auger and the vertical auger together form the feeding mechanism which fills the stuffing into the wrapper. The first pressing edge and the second pressing edge together form the pressing-breaking mechanism which is configured to seal and break food edges. The extrusion forming mechanism and the feeding mechanism can be integrated due to a suitable conical structure. The casing, as well as an external profile and an inner cavity of the inclined auger have an inverted cone shape.
