Solution Overview

Problem

Current coffee preparation methods require skilled Baristas to set and follow specific parameters for roasting and grinding, limiting accessibility to high-quality coffee without single-serve packaging.

Innovation Solution

A roasting and grinding apparatus that uses reading and control units to identify coffee bean characteristics, adjusting roasting and grinding parameters through AI, allowing for flexible preparation of various coffee beverages without the need for specialized skills, using multipack systems and accessory-devices for extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If skilled Baristas manually set and follow specific parameters for roasting and grinding, then high-quality coffee preparation is achieved, but the process requires specialized skills and knowledge

Engineering Contradiction:
Improvecoffee preparation qualityVSAvoidoperator skill requirement
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs self-diagnosis and self-adjustment by automatically detecting coffee bean characteristics through sensors and adjusting roasting and grinding parameters without human intervention. The control unit autonomously manages the preparation process based on detected parameters, eliminating the need for skilled operators while maintaining high coffee quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical adjustment of parameters by Baristas is replaced with an automated control system that uses sensors to detect coffee characteristics and electronically controls roasting and grinding parameters. This substitution of manual mechanical operations with automated sensing and control achieves precision without requiring specialized human skills

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If fully automatic machines are used for coffee preparation, then operator skill is not needed, but flexibility in preparation methods is reduced

Engineering Contradiction:
Improveoperator skill requirementVSAvoidpreparation method flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts its operation mode based on detected coffee characteristics. The control unit adjusts roasting and grinding parameters in real-time according to the specific properties of each coffee batch, allowing flexible preparation while maintaining automated operation. This dynamic adjustment capability provides both automation and adaptability

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If single-serve packaging systems are used, then preparation simplicity is improved, but product flexibility and quality control are reduced

Engineering Contradiction:
Improvepreparation simplicityVSAvoidcoffee type flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system automatically detects coffee bean characteristics and adjusts parameters without requiring pre-packaged single-serve formats. Each coffee batch is individually analyzed by sensors, and the control unit autonomously optimizes roasting and grinding settings, achieving both simplicity and flexibility without single-serve packaging constraints

Inventive Principle:
Principle #25Self-service
