Beverage Capsule Optical Marker Layout for Reliable Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage capsule recognition systems are unreliable due to issues such as foreign objects covering or dirtying markers, release of recognition substances into beverages, and failure to perforate multilayer sealing films, leading to incorrect capsule identification and infusion failures.
Innovation Solution
A flexible laminate recognition component positioned inside the capsule cover, attached at one side and protruding into the capsule, which flexes during infusion, remains exposed for optical verification, and does not obstruct fluid flow, ensuring reliable recognition and infusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permeable support with recognition substance is inserted into the capsule, then capsule recognition is enabled, but the recognition substance may be released into the beverage and foreign objects may cover or dirty the marker
Solution Approach 1:
The recognition system is segmented into separate functional components: the recognition marker is positioned on the outer surface of the closure film where it can be read optically without contact with infusion powder, while the infusion fluid passes through the capsule body without contacting the marker. This spatial segmentation prevents contamination of the recognition substance while maintaining reliable capsule identification.
2Reliability
If a multilayer closure film with recognition substance is used, then capsule recognition is enabled, but the inner layer may not be properly perforated by the heated perforator, preventing fluid injection
Solution Approach 1:
The closure film structure is segmented into distinct layers with separate functions: an outer layer containing the recognition marker for optical identification, and an inner layer designed for perforation and sealing. This segmentation allows the recognition function to be performed without interfering with the perforation process, eliminating the conflict between recognition accuracy and injection reliability.
Solution Approach 2:
The recognition marker is extracted from the inner sealing layer and positioned on the outer surface of the closure film. This extraction allows the recognition system to operate independently from the perforation mechanism, so the heated perforator can properly pierce the sealing layers without thermal deformation affecting recognition accuracy.
3Reliability
If the recognition component obstructs the fluid flow path, then recognition can be performed, but fluid injection and infusion are blocked
Solution Approach 1:
The recognition component is positioned on the outer surface of the closure film in a plane that does not obstruct the fluid flow path through the capsule body. The optical recognition system operates in a different spatial dimension (external surface reading) compared to the fluid injection path (internal volume flow), allowing both functions to coexist without interference.
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
The flexible laminate recognition component ensures robust and reliable capsule identification, avoiding false negatives and fluid flow obstruction, while maintaining the integrity of the sealing film and enhancing infusion efficiency.
Implementation Method 1
said recognition component consists of a flexible laminate component... positioned with the protruding end part, opposite to that connecting with the cover, positioned below the central part of the cover so as to allow said protruding end part, free from the connection with the cover, to be able to be moved by the perforator, keeping it intact, during the perforation of the sealing film and remaining elastically flexed
