Movable Extraction Plate for Multi-Diameter Capsule Beverage Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation systems using capsules face inefficiencies in extracting different amounts of fluid due to shape variations, which can complicate handling and appearance, and require precise placement, necessitating a system that can adapt to various capsule sizes without compromising efficiency or aesthetics.
Innovation Solution
A brew chamber system with a movable extraction plate and biasing members that adjust to accommodate capsules of different diameters, allowing for efficient fluid extraction and maintaining a consistent appearance by using a central and peripheral portion that moves relative to each other, and includes relief elements for piercing the capsule.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If capsules with different shapes are used to accommodate different ingredient volumes, then the amount of ingredients can be varied, but the appearance deteriorates and handling becomes difficult
Solution Approach 1:
The extraction plate is made movable relative to the brew chamber wall, allowing it to dynamically adjust its position based on the capsule diameter. This enables the system to adapt to different capsule sizes while maintaining a consistent capsule shape for uniform appearance and easy handling.
Solution Approach 2:
The system changes the parameter of extraction plate position rather than capsule shape. By varying the extraction plate's location (first position for smaller capsules, second position for larger capsules), the system accommodates different ingredient volumes while keeping capsule geometry constant.
2Adaptability or versatility
If capsules with different shapes are used to accommodate different ingredient volumes, then the amount of ingredients can be varied, but precise placement is required which increases complexity
Solution Approach 1:
The system uses the capsule's own flange diameter as the determining factor for extraction plate positioning. The larger flange diameter of second-type capsules automatically triggers the extraction plate to move to the second position, eliminating the need for complex external sensing or manual configuration.
Solution Approach 2:
The system changes the parameter of extraction plate position based on the capsule's inherent geometric parameter (flange diameter). This passive adaptation reduces device complexity by using the capsule's own characteristics to drive the adjustment mechanism.
3Device complexity
If a standard size capsule is used, then the apparatus is simple, but it is insufficient for increased amount of ingredients
Solution Approach 1:
The brew chamber is designed to universally accept both first-type and second-type capsules with different flange diameters. The extraction plate's ability to move between two positions provides multi-functionality, allowing the same apparatus to handle both standard and increased ingredient volumes without requiring separate devices.
Solution Approach 2:
The movable extraction plate provides dynamic adaptability within a simple apparatus structure. Rather than creating complex fixed chambers for different capsule sizes, the system uses a single dynamic element that adjusts its position to accommodate varying ingredient amounts.

AI summary
A system (1) and method for preparing a consumable beverage. The system (1) comprises an apparatus (2) including a first brew chamber part (18) having a cavity (24) for selectively holding an exchangeable first or second capsule (4A,4B). An exit area (13B) of the second capsule (4B) has a diameter (DB) that is larger than a diameter (DA) of an first exit area (13 A) of the first capsule (4A). The apparatus includes a second brew chamber part (20) for closing the first brew chamber part (18) around the first or second capsule. The second brew chamber part (20) has an extraction plate (30) for abutting against the first or second exit area (13A, 13B). The extraction plate (30) includes a central portion (32) and a peripheral portion (34). The central portion (32) is movable relative to the peripheral portion (34).
