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
Engineering Contradiction Analysis
1Manufacturing precision
If preparation parameters are fixed based on portion code, then manufacturing precision is improved, but adaptability deteriorates
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.
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.
2Adaptability or versatility
If user input is allowed to adjust parameters, then adaptability is improved, but device complexity increases
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.
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.
3Ease of operation
If multiple preparation parameters are adjustable, then user satisfaction is improved, but loss of information increases
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.

AI summary
A method is used to operate a beverage-making machine (1), to produce a finished product using a single-portion pack (3) and in accordance with specified preparation requirements. The method has the following steps: sensing a single-portion code (33) from a single-portion pack (3) by means of a portion-detection unit (132); determining first preparation parameters of the specified preparation requirements, said parameters being assigned to the single-portion code (33) and stored in the beverage-making machine (1), and determining second preparation parameters of the specified preparation requirements, wherein at least one of the first and/or second preparation parameters is an adaptable preparation parameter, and at least one preparation parameter is non-adaptable; sensing user input for adapting the at least one adaptable preparation parameter; preparing the finished product in accordance with the specified preparation requirements using at least one adapted preparation parameter.
