Beverage Cartridge Recognition Through Flow Resistance Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage makers require specific components like barcode readers to recognize beverage cartridges, increasing costs and limiting the use to only coded cartridges, whereas they should be able to automatically determine suitable parameters for processing various ingredients without additional components.
Innovation Solution
The method involves measuring flow characteristics influenced by the resistance of the beverage ingredient containing member, comparing them to predetermined characteristics, and selecting appropriate parameters for the brewing process, eliminating the need for coded cartridges and additional readers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a barcode reader is used to recognize beverage cartridges, then automatic recognition and parameter selection is achieved, but the cost of the system increases and compatibility is limited to coded cartridges only
Solution Approach 1:
The beverage cartridge itself provides the identification information through its physical structure (flow resistance characteristics) without requiring external coding or reading components. The system measures the natural flow resistance of the cartridge to identify its type, allowing the cartridge to 'identify itself' through its inherent physical properties rather than requiring added barcode labels and readers
Solution Approach 2:
The identification function is extracted from the cartridge by measuring a physical property (flow resistance) that naturally varies with cartridge type, rather than embedding identification codes in the cartridge. This separates the identification mechanism from both the cartridge design and the reader system, using only the beverage maker's existing pump and measurement capabilities
2Adaptability or versatility
If a barcode reader is used to recognize beverage cartridges, then automatic recognition is achieved, but additional specific components are required in the beverage maker
Solution Approach 1:
The flow resistance measurement approach allows the beverage maker's pump and measurement system to serve multiple functions: both to deliver the beverage and to identify the cartridge type. The same fluid delivery mechanism that is essential for making the beverage also provides the identification signal, eliminating the need for separate recognition components
Solution Approach 2:
The cartridge's physical structure itself provides the identification information through its flow resistance characteristics. Different cartridge types have different flow resistances due to their design, so the cartridge naturally 'encodes' its identity in its flow characteristics without requiring additional labels, codes, or reading components
3Device complexity
If flow characteristics are measured to identify beverage ingredients, then no additional components are needed and compatibility is improved, but the measurement system must accurately detect flow resistance variations
Solution Approach 1:
The system continuously monitors flow characteristics during the beverage delivery process and uses this feedback to identify the cartridge type. The measurement is integrated into the normal operation, with the controller adjusting parameters based on the measured flow resistance to achieve both identification and optimal beverage preparation

AI summary
A method for determining a suitable parameter for a process of making a beverage by conducting fluid through at least one member containing at least one beverage ingredient in a beverage maker that receives and processes various types of beverage ingredient containing members, the method includes realizing a flow of fluid through a beverage ingredient containing member of a particular type; and measuring a characteristic of the flow which is influenced by a flow resistance of the beverage ingredient containing member. The method further includes comparing the measured flow characteristic to a set of predetermined flow characteristics associated with the various types of beverage ingredient containing members; and determining at least one parameter for a further process of making a beverage by selecting a parameter related to the predetermined flow characteristic to which the measured flow characteristic is closest.
