Solution Overview

Problem

Existing coffee bean grinders are difficult to clean, leading to residual coffee powder that can mix with freshly ground coffee, resulting in impure taste.

Innovation Solution

A bean grinder container with a detachable grinding disc and connection assembly, allowing for easy removal and cleaning of the grinding disc, and an adjustable mechanism for controlling the fineness of coffee powder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the grinding disc is fixed inside the bean grinder, then the grinding structure is stable, but the cleaning becomes difficult

Engineering Contradiction:

Improvegrinding structure stabilityVSAvoidcleaning ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The bean grinder is divided into separable components: the cup body, the connection assembly, and the grinding disc. The grinding disc is detachably connected to the connection assembly, allowing it to be separated from the cup body for easy cleaning while maintaining structural stability during operation.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the grinding disc is made detachable for easy cleaning, then the cleaning ease improves, but the structural complexity increases

Engineering Contradiction:

Improvecleaning easeVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

3Quantity of substance

If the cup body diameter is increased to accommodate larger grinding disc, then the grinding capacity improves, but the coffee powder scattering increases

Engineering Contradiction:

Improvegrinding capacityVSAvoidcoffee powder scattering

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The connection assembly includes an adjusting mechanism that allows the grinding disc to be positioned at different heights relative to the cup body. By dynamically adjusting the grinding disc position, the system optimizes the gap between the grinding disc and cup body, preventing coffee powder scattering while maintaining adequate grinding capacity.
