Solution Overview

Problem

Existing grinders have complex structures and large volumes, making them inconvenient to carry and use, with complex designs that complicate operation and maintenance.

Innovation Solution

A compact grinder design with a transversely arranged power mechanism, feeding assembly, and power supply, featuring a detachable feeding assembly for easy cleaning and carrying, and an ergonomic switch button for easy access, along with a grinding mechanism comprising male and female grinding heads with adjustable grinding thickness and a sealing mechanism to prevent dust entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a traditional grinder structure is used, then the grinding function is achieved, but the structure becomes complex and volume increases

Engineering Contradiction:
Improvestructure complexityVSAvoidgrinder volume
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The patent combines the power mechanism, power supply mechanism, and feeding assembly into a single integrated housing structure. These three components are transversely arranged within the same housing space, merging what could have been separate units into one compact device, thereby reducing overall volume and structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a traditional longitudinal arrangement of components to a transverse arrangement within the housing. This dimensional reorganization allows for more efficient space utilization, reducing the overall footprint and volume of the grinder while maintaining all necessary functions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the feeding assembly is fixed, then the structure is stable, but cleaning and carrying become inconvenient

Engineering Contradiction:
Improvecleaning convenienceVSAvoidassembly stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The feeding assembly is designed as a detachable, separable component from the main housing. This segmentation allows the feeding assembly to be easily removed for cleaning or replacement, improving ease of operation and maintenance while the remaining housing structure maintains its stability.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the switch button is placed on the side, then the structure is simple, but accessibility becomes poor

Engineering Contradiction:
Improveswitch accessibilityVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The switch button is positioned on the top surface of the housing at a location optimized for user accessibility. This local modification to the housing structure places the control element where it is most easily reached and operated, improving ease of operation with minimal impact on overall structural complexity.

Inventive Principle:
Principle #3Local quality
