Solution Overview

Problem

Beverage preparation machines lack the ability to accurately determine and adjust preparation parameters to suit the specific properties of the beverage variant and its starting materials, leading to suboptimal beverage production.

Innovation Solution

A method for operating a beverage preparation machine that involves detecting a portion code from a portion pack, determining both fixed and adjustable preparation parameters, allowing user input to adjust the latter, and preparing the beverage according to the adjusted parameters, ensuring product-specific settings while considering user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If preparation parameters are fixed based on portion code, then manufacturing precision is improved, but adaptability deteriorates

Engineering Contradiction:
Improvepreparation parameter accuracyVSAvoiduser adjustment flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The preparation parameters are segmented into two categories: fixed parameters (first preparation parameters) that are determined by the portion code and stored in the machine, and adjustable parameters (second preparation parameters) that can be modified by the user. This segmentation allows the system to maintain both precision through pre-determined parameters and adaptability through user-adjustable parameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a static parameter system to a dynamic one where preparation parameters can be adjusted in real-time based on user input. The control unit is configured to accept user inputs that modify at least one preparation parameter, enabling the system to adapt dynamically while maintaining the structured foundation provided by the portion-specific parameters.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If user input is allowed to adjust parameters, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveparameter adjustment capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it stores the portion-specific preparation parameters, processes user inputs for parameter adjustment, and coordinates the brewing process. By making the control unit multi-functional, the system avoids adding separate dedicated components for each function, thereby managing complexity while providing comprehensive parameter adjustment capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically retrieves preparation parameters based on the detected portion code without requiring manual configuration by the user. This self-service approach reduces the complexity of the user interface and control logic, as the system autonomously determines the base parameters and only requires user input for adjustments.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If multiple preparation parameters are adjustable, then user satisfaction is improved, but loss of information increases

Engineering Contradiction:
Improveuser preference customizationVSAvoidparameter configuration complexity
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary action by pre-determining and storing the optimal preparation parameters for each portion type in the machine's memory. This preliminary configuration reduces the information burden on the user, as the system has already processed and stored the complex parameter relationships, requiring the user only to make simple adjustments if desired.

Inventive Principle:
Principle #10Preliminary action
