Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food cutters either have a simple structure making them inconvenient to operate and lacking in functions, or a complex structure that is difficult to use, clean, and costly.
Innovation Solution
A food cutter design featuring an operating frame with a push-pull mechanism, detachable knives, and elastic connection for smooth operation and easy cleaning, along with chutes and clearance grooves for guiding and resetting the cutting tools, allowing for various cutting shapes and consistent cutting results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual cutter is simply mounted on a board, then the structure is simple, but the device is inconvenient to operate and lacks functions
Solution Approach 1:
The cutter is divided into a stationary knife fixed on the board and a movable knife mounted on a sliding rack, allowing independent movement of the cutting components to achieve both simplicity and operational convenience
Solution Approach 2:
The movable knife is mounted on a sliding rack that can move back and forth along guide rails, transforming the static simple structure into a dynamic system that maintains simplicity while enabling convenient operation through controlled movement
2Adaptability or versatility
If the food cutter has a complicated structure, then it may have more functions, but it is troublesome to operate, inconvenient to clean and high in cost
Solution Approach 1:
The cutter components are segmented into detachable parts including the movable knife, sliding rack, and guide rails, allowing easy separation for cleaning while maintaining functional versatility during operation
Solution Approach 2:
The sliding rack mechanism serves multiple functions: it holds the movable knife, provides guidance through rails, enables back-and-forth cutting motion, and allows easy removal for cleaning, reducing overall structural complexity while maintaining versatility
3Ease of manufacture
If a detachable movable knife is used, then cleaning is easier, but the structure becomes more complex
Solution Approach 1:
The knife system is segmented into a stationary knife fixed on the board and a movable knife mounted on the sliding rack, allowing the movable knife to be easily detached and cleaned separately without complicating the overall structure
Solution Approach 2:
The movable knife is extracted as a separate detachable component from the main structure, mounted on the sliding rack for easy removal and cleaning, while the rack itself remains a simple guiding mechanism

AI summary
A food cutter induces an operating frame, a push-pull mechanism and an elastic connecting piece. A mounting cavity and a feeding hole are formed in the operating frame; and the push-pull mechanism is mounted in the mounting cavity and connected with the operating frame in a sliding manner. The push-pull mechanism includes a push-pull rack, a stationary knife and a movable knife; the stationary knife is fixedly mounted on the push-pull rack; the movable knife is detachably mounted on the push-pull rack and positioned below the stationary knife; and a discharging hole is formed in the push-pull rack and communicated with the feeding hole and the mounting cavity. One end of the elastic connecting piece is fixedly connected with the operating frame, and the other end is fixedly connected with the push-pull rack.
