Coded Insert Control for Beverage Cartridge Parameter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation machines, such as those using TASSIMO systems, lack the ability to modify dispensation parameters of already encoded beverage cartridges, limiting user control over beverage characteristics like volume, temperature, and flow rate, especially for converting hot beverages into iced versions.
Innovation Solution
A coded insert is introduced, which is separate from the cartridge and insertable into the brew head, containing a secondary code that provides alternative operating instructions to the machine for modifying the beverage dispensation parameters, allowing for changes in volume, temperature, and flow rate, and can be used to convert hot beverages into iced versions without requiring a separate card reader or mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate card reader mechanism is added to modify dispensation parameters, then user control over beverage characteristics is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The coded insert is nested within the cartridge structure, fitting inside the brew head alongside the cartridge. This nested arrangement allows the secondary code to be read by the existing code reader without adding external mechanisms, thereby modifying dispensation parameters while maintaining device simplicity.
Solution Approach 2:
The coded insert acts as an intermediary element between the cartridge and the code reader. It provides the secondary code that modifies the primary code's instructions, enabling parameter changes without requiring a separate card reader mechanism. The insert mediates the interaction between the fixed cartridge code and the machine's brewing parameters.
2Adaptability or versatility
If a coded insert is added to modify dispensation parameters, then beverage versatility is improved, but manufacturing cost increases
Solution Approach 1:
The system is segmented into three independent components: the cartridge containing the primary code, the separate coded insert containing the secondary code, and the brew head with code reader. This segmentation allows each component to be manufactured separately using existing processes, avoiding the need to redesign the entire system and thereby controlling manufacturing costs while achieving beverage versatility.
Solution Approach 2:
The coded insert is designed to work with existing cartridges and the existing code reader mechanism. By making the insert universal and compatible with current infrastructure, it enables beverage parameter modification without requiring expensive new manufacturing equipment or system overhauls.
3Adaptability or versatility
If the coded insert is read instead of the primary code, then modified beverage parameters are achieved, but the primary code functionality is lost
Solution Approach 1:
The system dynamically selects which code to read based on the presence of the coded insert. When the insert is detected in the brew head, the code reader prioritizes reading the secondary code from the insert. When the insert is absent, the system defaults to reading the primary code from the cartridge. This dynamic behavior allows flexible switching between standard and modified beverage parameters without permanent loss of functionality.
