Retractable Capsule Guide for Multi-Size Extraction Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage machine devices face challenges in reliably handling capsules of different sizes due to complex mechanical principles and the risk of improper alignment, which can lead to damage and inefficient brewing processes.
Innovation Solution
A device with movable parts that include a third part for guiding and stopping capsules, featuring a flange section that adjusts positions to accommodate various capsule sizes, ensuring secure handling and extraction by allowing the passage of larger capsules when necessary, and utilizing stop means to maintain the capsule during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanical principle with multiple movable parts is used for capsule extraction, then the device can handle capsule positioning, but the device complexity increases and is unsuitable for low-cost machines
Solution Approach 1:
The patent extracts the guiding function from the movable extraction parts and places it in a separate stationary third part (guide member). This separation allows the extraction parts to focus solely on the extraction movement while the guide member handles positioning, thereby reducing the complexity of the movable parts while maintaining capsule handling capability.
Solution Approach 2:
The third part (guide member) acts as an intermediary element between the capsule insertion path and the extraction chamber. It provides a dedicated guiding path that mediates the capsule's movement from the external insertion path into the extraction chamber, ensuring proper alignment without requiring the extraction parts to perform both guiding and extraction functions.
2Manufacturing precision
If the flange section remains in the first position to guide the capsule, then capsule guidance is maintained, but it blocks the passage of larger capsules and interferes with movable parts
Solution Approach 1:
The flange section is made movable between a first position (for guiding smaller capsules) and a second retracted position (for accommodating larger capsules). This dynamic adjustment allows the guide member to adapt its geometry based on capsule size, maintaining precise guidance when needed while clearing the path for larger capsules when required.
Solution Approach 2:
The flange section is positioned in the first guiding position before capsule insertion to ensure proper alignment. After the capsule is successfully guided and inserted, the flange section is retracted to the second position as a preliminary action to prevent interference with subsequent operations or to accommodate different capsule types.
3Measurement precision
If stop means are used to maintain capsule position during movement, then capsule positioning accuracy is improved, but the device requires additional components
Solution Approach 1:
The stop means are integrated into the third part (guide member) rather than being separate components. The guide member combines the functions of guiding the capsule along the insertion path, positioning it at the extraction chamber entrance, and providing stop means to maintain positional accuracy during the extraction operation, thereby reducing the total number of components.

AI summary
A device (1) handles a capsule (2a, 2b) having a flange (2a′, 2b′). The device comprises: a first part (10) and a second part (20) that are relatively movable across a space (3a, 3b) from a transfer position for inserting and/or removing such capsule (2a, 2b) to an extraction position for extracting such capsule; a third part (30) for guiding such capsule (2a, 2b) to in between the first and second parts (10,20) when in the transfer position; and stop means (32a,32b). The stop means are configured for successively: stopping the capsule (2a, 2b) in between the first and second parts (10, 20) in the transfer position; maintaining the capsule while the first and second parts (10, 20) are relatively moved from the transfer position towards the extraction position to receive the capsule; and allowing a liberation of the capsule from the stop means after reception of the capsule by at least one of the first and second parts (10,20) while relatively moving towards the extraction position. The third part (30) has a flange section (300) that has a first position for engaging with and guiding the capsule flange (2a′, 2b′) when the first and second parts (10, 20) are in the transfer position before liberation of such capsule (2a, 2b) from the stop means (32a, 32b). The flange section (300) in the first position extends into such space (3a, 3b), the flange section (300) being moved after the capsule liberation from its first position to a second position in which the flange section (300) is retracted from the space (3a, 3b) to allow a crossing thereof by the at least one of the first and second parts (10, 20).
