Garlic Press Pivot Structure for Cleanable, Reliable Comminution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional garlic presses often fail to provide reliable pressing results, are difficult to clean, and lack ergonomic design and aesthetic appeal, with limited accessibility for cleaning and replacement of comminution units.
Innovation Solution
A food press design featuring pivotally connected lever arms with a press plate and a comminutor unit secured by pivot devices, allowing for effective pressing, easy cleaning, and interchangeable comminutor units for varying comminution results, with a cleaning device and accessible components for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the garlic press uses a traditional design with lever arms and a grid, then it can perform pressing function, but the material can be moved sideways and pressing reliability is poor
Solution Approach 1:
The garlic press is divided into separate modular components: a body portion, a lever arm, and a removable comminutor unit. This segmentation allows each component to be optimized independently - the body provides stable material positioning while the comminutor unit delivers reliable pressing through its structured grid design.
Solution Approach 2:
The lever arm is designed to pivot between a stored position and a pressing position, transforming the static structure into a dynamic system. This dynamic movement allows the user to apply force efficiently while maintaining stable material positioning during the pressing action.
2Ease of manufacture
If the press grids are made replaceable, then cleaning is simplified, but the device complexity increases
Solution Approach 1:
The comminutor unit is designed as a separate removable component from the body portion, allowing it to be easily detached for cleaning or replacement. This segmentation provides full cleaning accessibility to all food-contact surfaces without requiring disassembly of the entire device.
Solution Approach 2:
The removable comminutor unit serves multiple functions: it can be removed for cleaning, replaced to vary comminution results, and securely reattached for use. This multi-functionality justifies the slight increase in assembly complexity by providing versatile maintenance and customization options.
3Reliability
If the comminutor unit is securely attached, then pressing reliability improves, but cleaning accessibility and replacement capability decrease
Solution Approach 1:
The connection between the comminutor unit and body portion is designed to be dynamically changeable - securely attached during pressing operations for reliability, but easily detachable for cleaning or replacement. The pivot connection allows the comminutor unit to be firmly positioned during use yet readily removable when needed.
4Ease of operation
If the lever arms are designed for ergonomic handling, then ease of operation improves, but the aesthetic appearance may be compromised
Solution Approach 1:
The lever arm is designed with asymmetric proportions - a longer handle portion for ergonomic gripping and a shorter functional portion for pressing. This asymmetric design optimizes both handling comfort and aesthetic balance, creating a visually appealing tool that is also ergonomically sound.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves efficient pressing, easy cleaning, and ergonomic handling with aesthetically appealing appearance, while allowing for the replacement of comminutor units to adjust the comminution outcome, enhancing user experience and functionality.
Implementation Method 1
a comminutor unit (6) which, at its inner end, is pivotally connected to said first lever arm (1) by means of a pivot device (3)
Implementation Method 2
an upper or second portion (2) or lever arm, which, on use of the food press, are interconnected to one another via a pivot device (3)... on pivoting of the upper portion (2) in a clockwise direction... the press plate (4) will be moved down into the accommodation space (5) and exercise pressure on the material which is located therein

AI summary
A food press, for example a garlic press, has a first handle (1) with an accommodation space (5) for the food. The first handle (1) is, via an openable pivot (3), connected to a second handle (2) which has a press plate (4). The food press further has a comminutor unit (6) with a perforated plate which, in a position of use, is adjacent the accommodation space (5) and through which the food is pressed. According to the present invention, the comminutor unit (6) is, at opposing ends, connected via a first and second non-openable pivot (9 and 17, respectively), to the first (1) and the second (2) handles, respectively. The openable pivot (3) includes recesses (15) on the first handle (1) and pins (16), which are insertable in the recesses (15) on the second handle (2).
