Solution Overview

Problem

Existing food processing apparatuses face manufacturing difficulties and complex assembly procedures, along with high torque requirements due to the need to prevent cutting blade deflection and bending during mechanical processing of food.

Innovation Solution

An apparatus with an elongate cutting tool supported at both ends by a slot and a support collar, allowing for axial stability and reduced torque requirements, where the cutting tool passes once per revolution through a processing region and recovers rotational speed in a recovery region without contacting the foodstuff.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cutting blade is mounted in an outer support ring with clips, then the blade is supported to prevent deflection, but the assembly becomes complicated and difficult to manufacture

Engineering Contradiction:
Improveblade support stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the support function from a complex clip-based mounting system and implements it through a simple slot in the housing that directly receives and supports the cutting blade. This eliminates the need for multiple clips and an outer support ring, reducing assembly complexity while maintaining blade support stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of mounting the blade to a support structure and then securing it with clips, the invention inverts the approach by having the blade directly engage with a slot in the housing. The housing itself provides the support function, eliminating the intermediate support ring and clips.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If the cutting blade is mounted in a solid disc on a rotational shaft with thrust bearings, then blade deflection is reduced, but manufacturing difficulty and cost increase

Engineering Contradiction:
Improveblade deflection controlVSAvoidmanufacturing ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts the essential support function from a complex solid disc with thrust bearings and implements it through a simple slot in the housing. The slot provides sufficient support to prevent excessive blade deflection without requiring expensive thrust bearings or heavy solid discs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces expensive, complex thrust bearing assemblies with a simple, inexpensive slot structure. The slot provides adequate support for the cutting blade's operational life without the need for precision-engineered bearing components.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If a heavy solid disc is used to support the cutting blade, then blade stability is improved, but the torque required to rotate the disc increases

Engineering Contradiction:
Improveblade stabilityVSAvoidtorque requirement
Core Design Contradiction:
ReliabilityVSPower

Solution Approach 1:

The invention extracts the support function from a heavy solid disc and implements it through a lightweight slot structure. This maintains blade stability by preventing excessive deflection while minimizing the moment of inertia, thereby reducing the torque required to accelerate and rotate the cutting blade.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical parameters of the support structure from a heavy, high-inertia solid disc to a lightweight slot configuration. This parameter change maintains structural support for blade stability while dramatically reducing the mass and moment of inertia, thereby lowering the torque requirement for rotation.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present application relates to an apparatus for processing a food stuff. The apparatus has a housing (2) and a cutting tool (5) for cutting a food stuff which is rotatably mounted in the housing. The cutting tool (5) rotates in the housing (2) about a rotational axis and has a radially extending cutting element (44). One end of the cutting tool (5) slides in a circumferentially extending slot in the housing as the cutting tool (5) is rotated in the housing (2). Therefore, the cutting tool (5) is supported in an axial direction by the housing (2). The present application also relates to a food processor.
