Solution Overview

Problem

Existing brewing devices face challenges in aligning portion capsules correctly during loading, leading to potential misalignment and difficulty in closing the brewing chamber, which complicates the filling process and increases the risk of errors.

Innovation Solution

Incorporating a holding element that aligns the portion capsule in the direction of the receiving element as the closure element moves, eliminating the need for precise alignment and ensuring the capsule is correctly positioned before insertion, thereby preventing contact with the edge of the receiving element and simplifying the loading process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the space between the end sections and the closure element is designed to be narrow to prevent capsule misalignment, then the capsule alignment is improved, but the difficulty of introducing the portion capsule increases

Engineering Contradiction:
Improvecapsule alignment precisionVSAvoidease of introducing capsule
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The holding element performs preliminary alignment of the portion capsule in the loading position before the closure element moves to extract it. This preliminary action ensures the capsule is correctly oriented and positioned, preventing misalignment during extraction while maintaining sufficient space for easy capsule introduction.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The holding element acts as an intermediary between the closure element and the portion capsule. It holds and aligns the capsule in the loading position, then releases it during extraction, mediating the interaction to achieve both precise alignment and easy operation without requiring narrow spacing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the holding element is made movable relative to the closure element to enable alignment, then the alignment capability is improved, but the device complexity increases

Engineering Contradiction:
Improvealignment capabilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The holding element combines multiple functions: it holds the capsule in the loading position, aligns the capsule before extraction, and then releases it during the extraction process. By merging these functions into a single element with simple relative movement, the design achieves alignment capability without excessive complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If precise alignment is required during loading, then the capsule positioning accuracy is improved, but the risk of striking the receiving element edge and causing errors increases

Engineering Contradiction:
Improvecapsule positioning accuracyVSAvoidrisk of striking edge
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The holding element performs preliminary alignment of the capsule in the loading position, ensuring correct positioning before extraction begins. This preliminary action reduces the risk of the capsule striking the receiving element edge during extraction, thereby improving reliability while maintaining positioning accuracy.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a brewing device (1) for extracting a portion capsule (2), comprising a receiving element (4) having a cavity (3) for the portion capsule (2), and a closing element (5), wherein the closing element (5) can be moved between a loading position (10) spaced apart from the receiving element (4) and an extracting position (11) closing the cavity (3), and wherein the brewing device (1) is provided with a retaining element (6) for retaining the portion capsule (2) in the loading position (10). Furthermore, the retaining element (6) is designed such that by moving the closing element (5) from the loading position (10) into the extracting position (11), the portion capsule (2) is oriented substantially in the direction of the receiving element (4) by means of the retaining element (6).
