Coffee Machine Cartridge Holder for User-Replaceable Decalcification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fully automatic coffee machines face challenges with lime calcification, requiring complex decalcification processes that often necessitate professional service and result in machine downtime, especially with fixed water connections.
Innovation Solution
A beverage machine with a cartridge holder system that allows for easy insertion of cartridges containing decalcifying agents, which are detected and activated by coding elements, enabling automatic diversion of water flow for decalcification and filtration, simplifying the process and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed water connection is used in coffee machines, then water supply is reliable, but decalcification becomes complicated and requires professional service
Solution Approach 1:
The patent divides the decalcification system into separable components: a removable cartridge containing the decalcifying agent is inserted into a cartridge holder that is accessible from the front. This segmentation allows users to easily replace decalcification cartridges without requiring professional service, while the fixed water connection remains intact for reliable water supply.
Solution Approach 2:
The cartridge holder acts as an intermediary component between the fixed water connection and the removable decalcification cartridge. It provides a standardized interface that enables easy cartridge replacement while maintaining the reliability of the fixed water connection, thus resolving the contradiction between reliable water supply and ease of decalcification.
2Reliability
If complex decalcification processes are implemented, then thorough cleaning is achieved, but machine downtime increases
Solution Approach 1:
The patent enables self-service decalcification by providing a user-accessible cartridge holder with easily replaceable cartridges. Users can perform decalcification themselves without calling professional service, significantly reducing machine downtime while maintaining effective cleaning through the standardized decalcification process.
Solution Approach 2:
The decalcifying agent is pre-loaded into cartridges that can be inserted into the cartridge holder in advance. This preliminary preparation allows users to quickly replace cartridges without needing to prepare decalcification solutions on-site, reducing the time the machine is out of service while ensuring thorough cleaning.
3Reliability
If professional service technicians are called for decalcification, then proper maintenance is ensured, but service availability and cost increase
Solution Approach 1:
The patent empowers users to perform decalcification themselves through the accessible cartridge holder and replaceable cartridges. This self-service capability eliminates the need for professional service technicians, giving users independence while maintaining proper maintenance through standardized cartridge designs that ensure correct decalcification procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables user-friendly adaptation to on-site water quality levels, simplifies operation, and ensures precise and targeted decalcification, reducing the need for professional service and minimizing downtime.
Implementation Method 1
a cartridge (21) having a cartridge connection (27) on an inlet end and a cartridge connection (28) on an outlet end, by means of which water supplied through the fixed water connection (11) to the beverage machine (10) when the cartridge (21) has been inserted then flows through the cartridge (21) and is thereby filtered and/or enriched with additives

AI summary
A beverage machine, in particular a coffee machine, prepares a beverage using water supplied via a fixed water connection to a hydraulic part arranged in the beverage machine and outputs the beverage at an outlet of the beverage machine. Maintenance is simplified by the fact that the beverage machine is provided with a cartridge holder which is accessible from the outside and into which a cartridge can be inserted in an exchangeable manner, the cartridge includes a cartridge connection on the inlet side and a cartridge connection on the outlet side, via which, in the inserted state of the cartridge, water supplied to the beverage machine via the fixed water connection flows through the cartridge and is thereby filtered and/or enriched with additives.
