Solution Overview

Problem

Conventional grinders for food and herbs experience frequent jamming due to intermixing of grinded and original pieces, limiting the amount of material that can be processed efficiently.

Innovation Solution

A grinding device with a grating member and a grinding handle featuring multiple teeth, where the grating member guides materials to a central portion and the grinding teeth cut items into fine pieces, which are collected through passage holes, reducing jamming and allowing for more consistent grinding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional grinders process food or herb items, then grinding function is achieved, but frequent jamming occurs due to intermixing of grinded and original pieces

Engineering Contradiction:

Improvegrinding consistencyVSAvoidjamming

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts grinded pieces from the grinding cavity through passage holes in the grating member during the grinding process. This continuous removal prevents grinded pieces from intermixing with original material, eliminating the root cause of jamming and improving grinding consistency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The grating member acts as an intermediary structure between the grinding cavity and storage container. It selectively allows grinded pieces to pass through while retaining larger original pieces, facilitating continuous removal without interfering with the grinding operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conventional grinders limit material quantity to avoid jamming, then jamming is reduced, but productivity decreases due to small portion processing

Engineering Contradiction:

Improvegrinding efficiencyVSAvoidgrinding consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The passage holes enable continuous removal of grinded pieces during the grinding process, maintaining consistent grinding action throughout. This allows larger quantities of material to be processed without interruption or jamming, significantly improving productivity while maintaining reliability.

Inventive Principle:

Principle #20Continuity of useful action

3Quantity of substance

If grinded pieces are not removed during grinding, then grinding cavity remains filled, but intermixing causes frequent jamming

Engineering Contradiction:

Improvematerial capacityVSAvoidjamming

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The system continuously extracts grinded pieces through passage holes during grinding, preventing accumulation and intermixing. This allows the grinding cavity to maintain optimal material quantity while avoiding jamming by actively removing processed material.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The grating member functions as a porous structure with passage holes that allow selective passage of grinded pieces. This porous design enables continuous removal of fine particles while retaining larger material, preventing jamming without limiting material capacity.

Inventive Principle:

Principle #31Porous materials

AI summary

A grinding device includes a storage base having a storage cavity, a grating member having a plurality of passage holes, a grinding handle having an actuating portion and a grinding cavity, at least one grinding member provided in the grinding cavity. The grinding member includes a protruding body protruding in the grinding cavity and extending in a radial direction of the grinding handle, and a plurality of grinding teeth provided on the protruding body. The grinding teeth extend in a transverse direction of the protruding body. When a predetermined amount of the food or herb items is disposed in the grinding cavity, and when the grinding handle is driven to rotate with respect to the storage base and the grating member, the grinding teeth are arranged to cut the food or herb items into fine pieces.
