Portion Pack Collar Release Mechanism for Simpler Beverage Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for preparing liquid food or beverages from portion packs are complex in structure and functionality, requiring intricate mechanisms for releasing the capsule, which complicates manufacturing and operation.
Innovation Solution
A device design where the positioning unit acts on the collar of the portion pack to release it from the insertion position by deformation, eliminating the need for special mobility and using a positioning unit with guide means that allow the collar to be clamped and deformed easily, enabling a simplified mechanism for capsule insertion and extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are used to hold the capsule in the insertion position, then the capsule can be securely held, but the device structure becomes complex and manufacturing becomes difficult
Solution Approach 1:
The patent removes the complex locking mechanism from the device structure and transfers the holding function to the capsule's own collar. The positioning unit simply provides guide means and a stop surface, while the collar's elastic deformation and geometric shape perform the actual holding and releasing functions, thereby extracting the complex mechanism from the device.
Solution Approach 2:
The capsule's collar is designed to be elastic and deformable, allowing it to automatically engage with the positioning unit's stop surface during insertion and then self-release when the chamber parts close. The collar's elastic properties enable it to perform the holding and releasing functions without requiring additional actuating mechanisms in the device.
2Ease of operation
If the positioning unit is designed with special mobility to free the collar, then the capsule can be released, but the positioning unit structure becomes more complex
Solution Approach 1:
The patent extracts the mobility function from the positioning unit and transfers it to the collar itself. The positioning unit remains essentially stationary, providing only guide means and a stop surface. The collar's elastic deformation during the closing process provides the necessary movement for release, eliminating the need for a mobile positioning unit.
Solution Approach 2:
Instead of designing the positioning unit to actively move and free the collar, the patent inverts the approach: the positioning unit remains fixed and allows the collar to deform and release itself through the closing action of the chamber parts. The passive stop surface becomes active through the collar's elastic deformation.
3Device complexity
If the collar is designed to be easily deformed, then the release mechanism is simplified, but the collar may be damaged during deformation
Solution Approach 1:
The patent applies local quality by designing the collar with different structural characteristics in different regions. The collar has overall sufficient strength to withstand deformation, but specific localized areas are designed to be more compliant to facilitate the necessary deformation during the release process, distributing the stress and preventing damage.

AI summary
The device (1) has chamber parts e.g. crown cap holder (5) and closure part (6), moved relative to each other for adjustment of a closing position of a positioning unit (4), and forming a chamber in the closing position. A medium is conducted through a portion package (2) in the closing position. The unit has an effect during movement of the chamber parts from an opening position into the closing position on a collar (3) such that the collar is released from the unit by deformation from a loading position. One of the chamber parts is moved in an axial direction (z). An independent claim is also included for an arrangement for preparing a liquid foodstuff or luxury food from packaged goods contained in a portion package i.e. crown cap.
