Method for operating a beverage preparation machine, and beverage preparation machine for carrying out such a method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation machines are not user-friendly and lack the flexibility to efficiently display and manage a large number of beverage variants, leading to potential operating errors due to limited graphical representation and selection complexity.
Innovation Solution
A method for operating a beverage preparation machine that utilizes a graphical interface with a selection mode featuring a selection area and a preview area, allowing users to intuitively select and confirm beverage variants, with options for theme selection, quick selection, and component modification, using a touch screen for intuitive operation and high variability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of beverage variants are displayed in the selection area, then the variety of beverage options is improved, but the display area required increases and the interface becomes more complex
Solution Approach 1:
The display interface is segmented into two distinct areas: a selection area for browsing beverage variants and a preview area for confirming the selected variant. This segmentation allows the system to display many beverage options without overwhelming the user, as the preview area provides focused confirmation space.
Solution Approach 2:
The interface transitions from a single-dimension display (showing only selection options) to a two-dimension display (showing both selection area and preview area simultaneously). This dimensional expansion allows users to compare multiple beverage variants while confirming their selection in a structured layout.
2Adaptability or versatility
If a large number of beverage variants are displayed graphically, then the selection flexibility is improved, but the risk of operating errors increases due to selection complexity
Solution Approach 1:
The preview area provides immediate visual feedback when a user selects a beverage variant, displaying the selected variant's details and allowing confirmation before finalization. This feedback mechanism reduces operating errors by ensuring users verify their selection intent.
Solution Approach 2:
The system performs a preliminary display of the selected beverage variant in the preview area before the final preparation begins. This preliminary action allows users to review and confirm their selection, preventing incorrect beverage preparation.
3Reliability
If the selection area and preview area are displayed simultaneously, then the user can confirm selections more reliably, but the device complexity increases
Solution Approach 1:
The graphical display interface serves multiple functions simultaneously: it displays beverage variants for selection, shows selected variant details for confirmation, and provides navigation controls. This multi-functionality reduces the need for separate physical components, managing device complexity while maintaining reliability.
4Ease of operation
If the selection area is hidden after user selection and only preview area is displayed, then the operating simplicity is improved, but the user cannot review available options
Solution Approach 1:
The preview area creates a visual copy of the selected beverage variant's information, allowing users to review the selection details without returning to the selection area. This copying mechanism preserves selection information while maintaining interface simplicity.

AI summary
The invention relates to a method for operating a beverage preparation machine, by means of which at least one coffee unit for dispensing coffee and an additive unit for dispensing a beverage additive is provided. A plurality of beverage variants are displayed by means of an at least partly graphical display in a selection mode, and the beverage preparation machine is controlled by a selection of a beverage variant, said selection being carried out by a user, such that the selected beverage variant is automatically prepared and dispensed from an outlet. The invention is characterized in that at least one selection region and a preview region are displayed in an at least partly graphical manner in the selection mode. A plurality of selectable beverage variants are displayed in an at least partly graphical manner in the selection region, and a current selection carried out by the user in the selection region is displayed in an at least partly graphical manner in the preview region. The beverage preparation machine is controlled when a starting element is actuated by the user such that the beverage variant displayed in the selection region is automatically prepared and dispensed from the outlet. The selection region and the preview region are displayed simultaneously in at least one first operating mode of the beverage preparation machine.
