Capsule Piercing Module With Coupled Retention and Perforation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage production systems face challenges in reliably opening sealed capsules within the production module, which is essential for efficient interaction with liquid ingredients to produce beverages.
Innovation Solution
The system employs a method and mechanism involving first and second capsule engagement members that retain and open the capsule using mechanically coupled perforation means, controlled by a common actuator, allowing precise and pressure-tight interaction with the capsule.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the capsule is opened before insertion into the beverage production module, then the ingredients are exposed to air and contamination, but the opening process becomes simpler and more reliable
Solution Approach 1:
The capsule is pre-opened at the inlet side before insertion into the beverage production module. This preliminary action allows the liquid to flow directly into the capsule during the brewing process, eliminating the need for opening mechanisms inside the module while preventing contamination by keeping the ingredients sealed until the moment of use.
Solution Approach 2:
The capsule opening is segmented into two separate operations: opening at the inlet side before insertion, and opening at the outlet side after insertion. This segmentation allows each opening operation to be optimized independently - the inlet opening is done in advance to avoid contamination, while the outlet opening is performed internally to maintain sealing until brewing.
2Extent of automation
If the beverage production module includes integrated capsule opening mechanisms, then the opening process is automated and consistent, but the device complexity increases
Solution Approach 1:
The capsule opening mechanisms are merged with the capsule engagement members. The first engagement member opens the inlet side and the second engagement member opens the outlet side, combining the functions of capsule retention and capsule opening into a single integrated system. This reduces overall device complexity while maintaining automation and consistency in the opening process.
3Manufacturing precision
If the capsule is retained in a defined position using clamping engagement, then the capsule opening precision is improved, but the risk of capsule damage increases
Solution Approach 1:
The clamping engagement applies localized pressure at specific points on the capsule rather than uniform compression. The engagement members are designed to clamp the capsule body firmly for precise positioning and opening, while the capsule inlet and outlet remain accessible and undamaged. This local quality approach maintains capsule structural integrity while achieving the precision needed for reliable opening.

AI summary
A capsule-based beverage production machine that comprises a module designed for producing a beverage on the basis of ingredients which are contained in a capsule. The module comprises: means for retaining the capsule in a fixed position, and means for perforation of the capsule, wherein the perforation means are controlled to perforate the capsule after the capsule is retained in the fixed position by the retaining means.
