Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing coffee grinding systems in coffee machines lack user-friendliness due to the inability to automatically adjust the grind level to match the optimal setting for specific coffee products, leading to suboptimal coffee quality.

Innovation Solution

A method that determines the actual grind level, compares it to a target grind level based on the selected coffee product, and provides user feedback on the discrepancy, allowing for automatic or manual adjustment to achieve the optimal grind level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the user manually sets the grind level separately from product selection, then the user has individual setting options, but the set grind level may not correspond to the optimum grind level for a specific product

Engineering Contradiction:

Improveindividual setting optionsVSAvoidgrind level accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system automatically compares the actual grind level with the target grind level determined from the selected coffee product and outputs information to the user based on the comparison. This feedback mechanism ensures the grind level corresponds to the optimum setting for the specific product while maintaining user awareness of the setting status.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The grinding mill automatically determines the target grind level based on the selected coffee product and compares it with the actual grind level without requiring manual user intervention. The system serves itself by automatically identifying the appropriate grind level for the chosen product.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the system provides automatic comparison and notification of grind level status, then user-friendliness is improved, but device complexity increases

Engineering Contradiction:

Improveuser-friendlinessVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system outputs information to the user based on the comparison between actual and target grind levels. This feedback provides clear guidance to users about whether the grind level is appropriate, significantly improving ease of operation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical adjustment and verification with an automated electronic system that uses sensors, processors, and display mechanisms to monitor and communicate grind level status, managing the complexity through electronic automation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If the system determines target grind level based on selected coffee product, then product quality is optimized, but loss of information occurs when actual and target grind levels do not match

Engineering Contradiction:

Improvecoffee powder finenessVSAvoidgrind level mismatch information

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The system outputs information to the user when the actual grind level does not match the target grind level, preventing loss of information by explicitly communicating the mismatch and enabling the user to adjust the settings accordingly.

Inventive Principle:

Principle #23Feedback
