Garlic Press Screw Drive With Automatic Thread Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing comminution devices require multiple turns to position the press ram for cutting and subsequent disengagement for refilling, complicating the operation and necessitating a separate changeover switch.
Innovation Solution
The comminution device automatically engages and disengages the screw drive threads based on the relative rotation of the housing parts, eliminating the need for a separate switch and simplifying the operation by integrating the switching mechanism into the rotational process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw drive is used to move the press ram, then the press ram can be positioned for cutting, but multiple turns are required which complicates operation
Solution Approach 1:
The patent implements a dynamic switching mechanism that automatically transitions the screw drive between engaged and disengaged states based on the rotational position of the first housing part relative to the second housing part. This dynamic adjustment allows the system to optimize between cutting mode (screw drive engaged) and refilling mode (screw drive disengaged), eliminating the need for manual operation changes and reducing the number of turns required.
2Ease of operation
If the press ram remains engaged for refilling, then cutting can be performed, but the press ram must be completely disengaged for refilling which adds operational steps
Solution Approach 1:
The patent merges the switching function into the existing rotational mechanism of the housing parts. The switching device utilizes the relative rotation between the first and second housing parts to automatically engage or disengage the screw drive threads, combining the positioning function with the switching function. This eliminates the need for a separate changeover switch and simplifies the overall device structure.
Solution Approach 2:
The system performs the switching operation automatically based on the rotational position of the housing parts, without requiring separate manual intervention. The screw drive mechanism itself facilitates its own engagement and disengagement through the integrated switching device that responds to the rotational state, making the system self-regulating and reducing operational complexity.
3Ease of operation
If automatic switching is implemented, then operation is simplified, but the switching mechanism must be integrated into the rotational process
Solution Approach 1:
The switching device serves multiple functions: it monitors the rotational position of the housing parts, determines the appropriate operational mode (cutting or refilling), and executes the engagement or disengagement of the screw drive. By making the switching mechanism multi-functional and integrating it into the existing rotational structure, the patent avoids adding separate complex control systems while achieving automatic operation.

AI summary
The invention relates to a comminution device for cutting food, in particular for cutting garlic, having a first housing part (1) and a second housing part (2), wherein the first housing part contains a cutting grid (3) and the second housing part contains an extrusion punch (4), and having a screw drive, by means of which the extrusion punch (4) is movable to the cutting grid (3) by rotating the first housing part (1) relative to the second housing part (2) in a rotation direction. The comminution device is characterized in that the comminution device has a switching device, which automatically switches the threads of the screw drive into engagement, independently of the axial relative position of the first housing part (1) relative to the second housing part (2), when the first housing part (1) is rotated relative to the second housing part (2) in the rotation direction, and/or automatically switches the threads of the screw drive out of engagement, independently of the axial relative position of the first housing part (1) relative to the second housing part (2), when the first housing part (1) is rotated relative to the second housing part (2) in the counter-rotation direction, opposite of the rotation direction.
