Beverage-parameter setting on a beverage maker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of fully automatic coffee machines often struggle to systematically set parameters for brewing coffee, leading to a time-consuming and error-prone process of trial and error, as they lack understanding of how parameter changes affect the taste of the coffee.
Innovation Solution
A method and device that allow users to compare two versions of the same beverage type with different parameter settings, enabling them to intuitively select their preferred taste by displaying and inputting preferences through a beverage maker or mobile terminal, with the system storing the optimal parameter settings for future use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users systematically adjust multiple beverage-preparation parameters to find optimal taste, then the precision of taste optimization improves, but the time and complexity of the process increases
Solution Approach 1:
The system prepares two beverages with parameter settings that represent extremes or significant differences in taste characteristics, rather than requiring users to test every possible parameter combination. This partial action approach allows users to identify their preference direction with fewer comparisons, reducing time while maintaining optimization precision.
Solution Approach 2:
The system implements a feedback mechanism where user selections are stored and used to guide subsequent parameter adjustments. The beverage maker remembers which beverage type the user preferred and uses this feedback to systematically adjust parameters in future comparisons, enabling efficient convergence to optimal taste settings over multiple uses.
2Adaptability or versatility
If users adjust multiple beverage-preparation parameters simultaneously, then the comprehensiveness of taste exploration improves, but the difficulty of identifying causal relationships increases
Solution Approach 1:
The system segments the parameter adjustment process into distinct steps, where typically one primary parameter is varied between the two beverage options at a time (e.g., brewing temperature in one comparison, then amount of grounds in another). This segmentation allows users to clearly identify which parameter caused the taste difference, reducing the difficulty of detecting parameter influences while maintaining comprehensive exploration.
Solution Approach 2:
The system systematically changes parameters between the two beverage options being compared, ensuring that differences are attributable to specific parameter adjustments rather than random variations. By controlling which parameters differ between options, the system makes it easier for users to detect and understand parameter influences on taste.
3Measurement precision
If the system offers detailed parameter adjustment options, then the precision of beverage customization improves, but the ease of operation decreases
Solution Approach 1:
The system performs automatic parameter adjustment based on user selections, eliminating the need for users to manually calculate or input specific parameter values. The beverage maker itself carries out the parameter changes between comparisons and stores the optimal settings automatically, making the precision customization process simple and intuitive for users.
Solution Approach 2:
The system pre-configures parameter settings for the two beverage options being compared, so users don't need to manually adjust multiple parameters during the comparison process. The parameters are prepared in advance with meaningful differences, allowing users to focus on taste preference rather than technical parameter adjustment.

AI summary
A method for controlling a beverage maker involves the steps of preparing a first beverage having a first value of a beverage-preparation parameter, preparing a second beverage having a second value of the beverage-preparation parameter different than the first value, receiving a user input that selects the first or the second beverage, and storing the beverage-preparation parameter of the selected beverage as a specification for the preparation of the beverage. A beverage maker includes a beverage-preparation device with at least one variable beverage-preparation parameter, which can assume at least two different values, and a control device configured to carry out the method.
