Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food dicing devices face issues with noise emission, increased wear, and complex handling due to the interaction between knife blades and support rollers, leading to uneven processing and potential damage.
Innovation Solution
A device design where the cutting tool's outer circumference is supported by a fixed position support device, eliminating the need for cyclic adjustment and reducing noise, with a ring element and coupling device for easy tool replacement and axial force diversion, using sliding friction for reduced wear and simplified cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the knife blades run against the conical outer surface of the support rollers with each revolution, then the axial force required to cut the material is generated, but the noise emission of the device increases
Solution Approach 1:
The patent introduces a cylindrical guide surface as an intermediary element between the knife blade and the support roller. The blade runs in this guide surface which is divided into multiple circumferential guide surfaces, mediating the interaction and reducing direct contact noise while maintaining the necessary axial cutting force generation
2Stability of the object's composition
If the knife blades run against the support rollers, then the blade position is maintained, but components of the material to be processed get between the support rollers and the outer circumference of the knife
Solution Approach 1:
The cylindrical guide surface is divided into multiple circumferential guide surfaces, creating segmented contact zones. This segmentation prevents material components from wedging between the blade and support roller while maintaining stable blade positioning through distributed contact points
3Device complexity
If the support rollers are set incorrectly, then the device structure remains simple, but increased wear or even damage to the blade or the support device occurs
Solution Approach 1:
The patent changes the geometric parameters of the guide surface, specifically providing it with a slightly larger diameter than the support roller and creating a radial gap. This parameter change ensures proper alignment and contact conditions that prevent excessive wear and damage while maintaining simple device structure
4Manufacturing precision
If a clamping device is used to adjust the axial position of the support rollers, then the blade position can be controlled, but the handling of the device becomes more complex
Solution Approach 1:
The device is designed to be self-aligning through the cylindrical guide surface geometry. The guide surface automatically guides the blade into the correct position during operation, eliminating the need for complex clamping devices and manual adjustments, thereby simplifying handling while maintaining precision

AI summary
The invention relates to a device (1) for cutting up processed goods, in particular for dicing foods, comprising a cutting tool (6) that rotates along a cutting grid (7) about a rotating axis, said tool being supported radially outward by way of at least one support device (21). According to the invention, the cutting tool (6) comprises at least one cutting blade (20) and a blade carrier provided near the outer periphery thereof that completely surrounds the blade, said carrier being for the purposes of abutting against the at least one radially outward-acting support device (21). The support device (21) preferably comprises hook-like latching elements (22) that are pivotably disposed at a housing section (5) and that sit against the upper axial surface (26) of an annular element (19) of the blade carrier in the latched position. This embodiment allows the support devices (21) and the device (1) as a whole to be very easy to hold, so that the device (1) is no longer reserved only for professional use. Also, the noise level during operation of the device can be reduced. Moreover, the device can also be cleaned easily, and can even be cleaned in the dishwasher with a suitable selection of materials.
