Solution Overview

Problem

Existing processing devices require multiple interchangeable disks or tool inserts for different shredding tasks, leading to increased accessory storage needs and complex tool changes.

Innovation Solution

A processing device with a single processing disk featuring multiple tool areas and a cover disk with adjustable positions, allowing for easy selection and use of different tools by positioning the cover disk relative to the processing disk, with only the exposed tool contributing to material comminution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple interchangeable processing disks or tool inserts are used for different shredding tasks, then different tool functions are achieved, but accessory storage needs and device complexity increase

Engineering Contradiction:

Improvetool function varietyVSAvoidaccessory quantity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple different tool areas are integrated onto a single processing disk, combining several tool functions that previously required separate disks or inserts. The processing disk is divided into multiple sectors, each containing different tool types (cutting tools, grating tools, shredding tools, etc.), allowing one disk to replace multiple interchangeable accessories.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The processing disk is designed as a universal component that can perform multiple shredding functions simultaneously. By incorporating diverse tool areas on one disk and using a selectively positionable cover disk, the system achieves multi-functionality without requiring users to store and manage multiple specialized accessories.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple interchangeable processing disks are used for different shredding tasks, then different tool functions are achieved, but tool change time and operation complexity increase

Engineering Contradiction:

Improvetool function varietyVSAvoidtool change simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The cover disk is designed to be selectively positionable relative to the processing disk, allowing dynamic selection of different tool areas during operation. The cover disk can be rotated or repositioned to expose different sectors of the processing disk, enabling quick tool selection without the need to physically change entire disks or inserts.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The processing disk is segmented into multiple independent sectors, each containing a specific tool type. The cover disk corresponds to these segments and can selectively cover or expose specific sectors. This segmentation allows independent selection and use of different tool areas without affecting other tools, simplifying the tool change process.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention relates to a processing device for comminuting processing material, which processing device has a processing disk having a plurality of different tool regions and has a covering disk having at least one opening, wherein the covering disk can be arranged in different positions on the processing disk. The processing disk and the covering disk arranged on the processing disk, in the particular position thereof relative to each other, form a jointly drivable unit. The covering disk makes it possible to easily select at least one desired tool region from the tool regions arranged on the processing disk.
