Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage capsules are not specifically designed for particular coffee machines, leading to potential safety issues and machine damage when incompatible capsules are used.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If capsules are made similar in design for market variety, then manufacturing cost and ease of manufacture are improved, but safety and machine compatibility are worsened due to incompatible capsules being used in wrong machines
Solution Approach 1:
An identifier is added to the capsule during manufacturing, enabling the beverage preparation machine to verify capsule compatibility before the brewing process begins. This preliminary identification prevents incompatible capsules from being used, thereby avoiding machine damage while maintaining simple capsule manufacturing processes.
Solution Approach 2:
The capsule system is segmented into two functional parts: the basic capsule structure (which remains simple for manufacturing) and the identifier component (which provides compatibility information). This segmentation allows capsules to maintain manufacturing simplicity while incorporating safety features through the separate identifier element.
2Reliability
If an identifier system is added to individualize capsules, then machine compatibility and safety are improved, but device complexity increases
Solution Approach 1:
The patent employs optical detection systems instead of complex mechanical verification mechanisms to read capsule identifiers. This substitution reduces mechanical complexity while maintaining reliable compatibility verification, as optical sensors can quickly identify capsules without complex physical interactions.
Solution Approach 2:
The identifier system is designed to serve multiple functions: it provides machine compatibility verification, enables traceability of capsule batches, and can potentially store additional product information. This multi-functionality justifies the added complexity by delivering multiple benefits from a single identifier component.
3Object-affected harmful factors
If detection systems are added to verify identifiers, then safety and compatibility control are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
Optical detection systems are used to read capsule identifiers, replacing what would otherwise require complex mechanical verification mechanisms. Optical sensors can quickly and accurately verify capsule compatibility without complex physical interactions, reducing overall system complexity while maintaining safety.
Solution Approach 2:
The capsule identifier system is designed to work passively with the detection system, requiring minimal active components in the machine. The identifier on the capsule essentially performs part of the verification work by presenting its identification information in a machine-readable format, reducing the burden on the machine's detection system.

AI summary
A beverage system for making a beverage that includes a single-serve capsule and a beverage machine. The capsule has a cavity containing a beverage material; a flange; a cover fastened to a top side of the flange; and an individualization identifier on a bottom side of the flange. The beverage machine includes: a capsule receptacle having a wall structure to receive the capsule; an optical sensor/detector positioned outside of the wall structure to direct a beam through a portion of the wall structure to read the identifier; a pump that supplies water into the portion capsule only after the identifier is read by the sensor/detector; a mandrel to pierce the cover in a region that is offset from the central axis; and a seal that seals against the cover in a region between a peripheral edge of the flange and the region of the cover pierced by the mandrel.
