Portion capsule having an identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portion capsules are not specifically designed for particular coffee machines, leading to potential safety issues and machine damage when used incorrectly.
Innovation Solution
Incorporating an identifier on the portion capsule that allows it to be individualized and recognized by the coffee machine, preventing unsuitable capsules from being inserted and ensuring compatibility through optical, mechanical, or electrical means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portion capsules are made similar and compatible with multiple machines, then manufacturing cost is reduced and versatility is improved, but safety issues arise and coffee machines may be damaged
Solution Approach 1:
An identifier element is introduced as an intermediary between the capsule and the coffee machine. This identifier serves as a mediator that enables the machine to recognize and verify capsule compatibility before operation, thus preventing machine damage while maintaining capsule versatility. The identifier acts as a communication bridge that resolves the conflict between universal compatibility and safety protection.
Solution Approach 2:
A detection system with sensor and reference comparison provides feedback to the coffee machine about capsule compatibility. The sensor detects the identifier, compares it against stored reference data, and provides feedback that determines whether the capsule is suitable for use. This feedback mechanism prevents incompatible capsules from being processed, thereby avoiding machine damage while allowing versatile capsule design.
2Reliability
If an identifier system is added to the portion capsule, then capsule individualization and machine compatibility control are improved, but device complexity increases
Solution Approach 1:
The identification function is extracted from the main capsule structure and implemented as a separate, dedicated identifier element. This extraction allows the identifier to be a simple, independent component that can be easily manufactured and integrated, minimizing the complexity increase while maintaining reliable identification and compatibility control functionality.
Solution Approach 2:
The identifier serves multiple functions simultaneously: it provides capsule individualization, enables machine recognition, ensures compatibility control, and prevents incorrect usage. By designing the identifier to fulfill multiple roles, the system achieves high reliability without proportionally increasing complexity, as a single element performs several critical functions.
3Object-affected harmful factors
If mechanical means are added to the media chute to prevent incorrect capsule insertion, then safety is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The identifier on the capsule serves as an intermediary that enables non-mechanical verification of compatibility. Instead of adding complex mechanical blocking mechanisms to the media chute, the identifier mediates the compatibility check through optical or electromagnetic detection, simplifying the manufacturing process while maintaining safety against incorrect capsule insertion.
Solution Approach 2:
The detection system replaces potential mechanical prevention mechanisms with non-mechanical sensing. Instead of using complex gearwheels or physical blockers in the media chute, the system uses sensors to detect the identifier and control capsule acceptance through electronic means, thereby reducing manufacturing complexity while improving safety.

AI summary
A beverage system for making a beverage that includes a single-serve capsule and a beverage machine. The capsule has a flange and a barcode on a bottom side of the flange. The beverage machine includes: a sensor/detector to read the barcode; a brewing chamber to receive the capsule; and a pump controlled to supply water into the capsule. The machine includes: a mandrel to pierce the cover in a region that is offset from the central axis; a seal that seals against the cover in a region between a peripheral edge of the flange and the region of the cover that is pierced by the mandrel; a pair of holding arms for engaging the capsule; and a dropping box for the capsule to fall into. The pump is controlled to push the water into the capsule only upon a determination that the read barcode agrees with a stored reference.
