Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional kitchen cutting tools are laborious, difficult to control, and often result in accidents or compromised food quality due to sticky vegetables and fixed blade spacing, while electric tools are inefficient and hard to maintain.
Innovation Solution
A new-type cutting tool with adjustable blade units, a protective plate, and elastic cutting edges or thin threads that can be operated with one hand, allowing for precise cutting without electricity and extending tool life by sharing energy consumption with the chopping board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional kitchen cutting tools are used, then cutting function is provided, but processing speed is slow and accuracy is difficult to control
Solution Approach 1:
The cutting tool is segmented into multiple parallel blades (at least two blades) arranged side by side, allowing simultaneous cutting of multiple portions of the material. This segmentation enables faster processing while maintaining control accuracy through the fixed spacing between blades.
Solution Approach 2:
The blade spacing is made adjustable rather than fixed, allowing the distance between adjacent blades to be dynamically changed. This enables the user to adapt the cutting tool for different cutting patterns (slicing, shredding, dicing) and material types, improving both processing speed and control accuracy for various tasks.
2Adaptability or versatility
If fixed blade spacing is used, then tool structure is simple, but cutting patterns are limited and food quality is compromised
Solution Approach 1:
The blade spacing is made adjustable rather than fixed, allowing the distance between adjacent blades to be dynamically changed. This enables the user to adapt the cutting tool for different cutting patterns (slicing, shredding, dicing) and material types, improving both processing speed and control accuracy for various tasks.
Solution Approach 2:
The cutting tool is designed to perform multiple cutting functions (slicing, shredding, dicing) using a single device with adjustable blade spacing. This multi-functionality eliminates the need for multiple specialized cutting tools while maintaining structural simplicity through a unified design.
3Power
If electric cutting tools are used, then cutting power is increased, but maintenance difficulty increases and electricity consumption is required
Solution Approach 1:
The invention replaces electric cutting mechanisms with a purely mechanical multi-blade system. The cutting power is achieved through the coordinated action of multiple blades and the user's manual force, eliminating the need for motors, power supplies, and complex electrical components. This substitution dramatically simplifies maintenance while providing sufficient cutting power for kitchen applications.
4Productivity
If single cutting tool is used, then tool structure is simple, but processing time for multiple cutting stages increases
Solution Approach 1:
The cutting tool is segmented into multiple parallel blades (at least two blades) arranged side by side, allowing simultaneous cutting of multiple portions of the material. This segmentation enables faster processing while maintaining control accuracy through the fixed spacing between blades.
Solution Approach 2:
Multiple cutting functions that would traditionally require separate tools or multiple sequential operations are merged into a single multi-blade cutting tool. The parallel blades work simultaneously to perform slicing, shredding, or dicing in one pass, dramatically reducing processing time while the integrated design keeps overall complexity manageable.

AI summary
The present invention is a new-type kitchen cutting tool suitable to be used in households, canteens, restaurants etc. It is an entirely-new multi-edge protective cutting tool consisting of several blade units and the supporting cutting tool holder for holding the blade unit, used for cutting the food material into slices, shreds and dices. The blade unit may be changed so that the food material may be cut into slices, shreds and dices with different sizes and thicknesses. The cutting tool edge, the thin thread functioning as the cutting tool edge and the chopping board may be protected through the combination of the protective plate and the elastic blade or the thin thread, greatly extending their service life. The present invention is featured as easy operation, convenient, safe, high efficiency, raw material-, energy- and time-saved, wide application range and good quality of processed products.
