Tofu Press Toggle Latch Mechanism for Liquid Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tofu presses are not portable, easy to use, or convenient, often requiring complex maintenance and failing to efficiently remove neutral liquid from tofu, which affects the firmness and flavor absorption of tofu.
Innovation Solution
A tofu press with a toggle latch mechanism that applies pressure to tofu using a tray and pressure member, featuring a linkage that increases tension gradually to compress tofu, allowing for efficient liquid removal and adjustable pressure settings, and a liquid-permeable tray for easy liquid collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If complex moving parts are used in tofu presses to apply pressure, then pressure application capability is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The pressure application mechanism is segmented into a tray, a pressure member, and a toggle latch system with separate components (arm, linkage, latch member). This allows each component to have a simple function while collectively achieving effective pressure application, reducing overall device complexity and maintenance needs.
Solution Approach 2:
The toggle latch mechanism utilizes dynamic movement of the arm between a first position (for engagement) and a second position (for pressure application). The linkage dynamically transitions from an engaged state to a tensioned state, providing automatic pressure application without complex control systems.
2Ease of operation
If a toggle latch mechanism is used to simplify the tofu press, then ease of operation is improved, but pressure control precision may worsen
Solution Approach 1:
The toggle latch mechanism is self-regulating through the geometric relationship between the arm, linkage, and latch member. As the arm rotates to the second position, the linkage automatically tensions and engages the latch member, providing consistent pressure without requiring user adjustment or measurement.
Solution Approach 2:
The mechanism changes the geometric parameters of the linkage system as the arm rotates, transforming the user's simple rotational input into controlled pressure output. The tension in the linkage varies with the arm's position, providing progressive pressure application.
3Productivity
If neutral liquid is not removed from tofu before marinating, then flavor absorption efficiency worsens, but the process becomes simpler
Solution Approach 1:
The tofu press serves multiple functions: it removes neutral liquid from tofu through applied pressure, and it can also be used to apply pressure during the marinating process to enhance flavor absorption. This multi-functionality addresses both liquid removal and flavor infusion needs.
Solution Approach 2:
The press is used to remove neutral liquid from tofu before the marinating process begins. This preliminary action prepares the tofu by reducing its liquid content, creating better conditions for subsequent flavor absorption during marination.
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 tofu press effectively reduces liquid content, making tofu firmer and easier to flavor, while being portable and requiring minimal maintenance, thus improving usability and consistency.
Implementation Method 1
The linkage may comprise an elastic material. In this way, the linkage may stretch. This may allow a gradual and/or smooth increase in pressure to the tofu within the tray.

AI summary
Tofu is typically sold saturated in liquid, and in order for the tofu to take on a desired flavour, the liquid content of the tofu must first be reduced. The present invention provides a method of reducing the liquid content of tofu and a tofu press 10, comprising: a tray 20 for receiving tofu 30 therein; a pressure member 80 for applying pressure to the tofu 30 within the tray 20; and a toggle latch 120 releasably coupleable between the tray 20 and the pressure member 80 such that pressure is applied to the tofu 30 within the tray by the pressure member 80.
