Solution Overview

Problem

Conventional methods for preparing turnovers lack efficiency in producing uniform, concave tortillas and require multiple devices, leading to increased preparation time and effort.

Innovation Solution

A device with a circular base element featuring a concave semicircular piece and a lever, utilizing four hinges for opening and closing, ensures even distribution and closure, allowing for the formation of uniform concave tortillas and the creation of a hollow space for filling, with optional engravings for decorative patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional methods are used to prepare turnovers, then multiple devices are required, but preparation time and effort increase

Engineering Contradiction:

Improveturnover production efficiencyVSAvoidpreparation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple functions (dough flattening, concave shape formation, sealing, and filling) into a single integrated device. The base element with concave semicircular piece and top element work together as one unit, eliminating the need for multiple separate devices and operations, thereby reducing preparation time and improving productivity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device performs multiple functions simultaneously: the base element with concave semicircular piece forms the dough into a concave shape, the top element seals the turnover, and the lever mechanism applies pressure for both flattening and closure. This multi-functionality allows a single device to replace several traditional tools, increasing efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If conventional methods are used to prepare turnovers, then multiple devices are required, but device complexity increases

Engineering Contradiction:

Improveturnover production efficiencyVSAvoidnumber of devices

Core Design Contradiction:

The patent integrates multiple functions (dough flattening, concave shape formation, sealing, and filling) into a single integrated device. The base element with concave semicircular piece and top element work together as one unit, eliminating the need for multiple separate devices and operations, thereby reducing preparation time and improving productivity

3Manufacturing precision

If conventional methods are used to prepare turnovers, then manual shaping is required, but manufacturing precision of uniform size is reduced

Engineering Contradiction:

Improveturnover size uniformityVSAvoidmanual shaping effort

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The base element features a concave semicircular piece with specific geometric dimensions that locally define the precise shape and size of the turnover. This fixed geometric structure ensures that each turnover receives identical shaping, guaranteeing uniform size and shape without requiring manual measurement or adjustment

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device pre-forms the concave shape in the dough through the fixed geometric structure of the base element before the sealing action. This preliminary shaping ensures that the dough is already uniformly formed and sized before the user completes the turnover assembly, reducing the need for manual shaping adjustments

Inventive Principle:

Principle #10Preliminary action

AI summary

Device to prepare turnovers which has a base element, a top contact element, and lever for closing. The base element has two parts which are joined by two hinges. One part is fixed and the other one performs a 180° opening and closing movement to form the turnover. This movable part has engravings on its interior surrounding walls which are marked in the dough when the two parts come together to form the pie. The outer edge of the periphery of the base element has a slope that serves to cut the dough excess of the turnovers. When the lever presses the top contact element against the base element a concave tortilla will form. Then, the concave tortilla is stuffed with your choice of filling and the movable part closes to form the turnover. Finally, the movable part opens and the turnover is taken out.
