Solution Overview

Problem

Existing beverage dispensers fail to ensure optimal beverage quality, particularly for espresso coffee, due to incorrect positioning of receptacles, leading to suboptimal froth formation and potential spatter, as users may not choose the appropriate holder position and distance for the beverage outlet.

Innovation Solution

A beverage dispenser with a cantilever-style receptacle holding part that rotates between deployed and retracted positions, equipped with sensors to detect the holding part's position and alert the user to adjust it correctly, ensuring the ideal distance for beverage dispensing, and an input device for selecting beverage sizes varying from 25 to 1000 ml.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the holder and drip-collecting system is positioned in the retracted position to accommodate larger receptacles, then the adaptability for different cup sizes is improved, but the beverage quality deteriorates due to increased distance from the beverage outlet

Engineering Contradiction:
Improveadaptability for different cup sizesVSAvoidbeverage quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The holder and drip-collecting system is designed to be movable between deployed and retracted positions, allowing dynamic adjustment based on receptacle size. This enables the system to adapt to different cup sizes while maintaining optimal beverage quality by positioning the holder correctly for each beverage type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A sensor detects the position of the holder and provides feedback to the control unit. The control unit monitors whether the holder is in the correct position and can alert the user or prevent operation if the position is incorrect, ensuring beverage quality is maintained through position verification.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the holder is positioned far from the beverage outlet to accommodate large receptacles, then the versatility for different beverage sizes is improved, but the beverage preparation quality deteriorates due to suboptimal froth formation and increased spatter risk

Engineering Contradiction:
Improveversatility for different beverage sizesVSAvoidspatter and froth quality
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The holder's position is made dynamic rather than fixed, allowing it to be close to the beverage outlet for small beverages (maintaining froth quality and preventing spatter) and retracted for large beverages. This resolves the contradiction between proximity for quality and distance for versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system determines the required holder position in advance based on the selected beverage type and alerts the user to adjust the holder before dispensing begins. This preliminary positioning ensures optimal beverage quality from the start of dispensing.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the holder is fixed in a single position, then the device complexity is reduced, but the adaptability for different receptacle sizes is worsened

Engineering Contradiction:
Improveholder positioning systemVSAvoidreceptacle size accommodation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

Instead of a fixed holder, the system implements a movable holder with two distinct positions (deployed and retracted). This adds minimal complexity while providing significant adaptability for different receptacle sizes, resolving the contradiction between simplicity and versatility.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention concerns a beverage dispenser (1) comprising a base (2) and a holding system that comprises a holding part(3) positionable beneath a beverage outlet (4) in order to accept a first, relatively small receptacle, and being configured and dimensioned to be moveable between a deployed holding position suitable for accepting the small receptacle and a second position in which the holding part is moved at least partly out of the way of the beverage outlet to create an unoccupied space in which a second, larger receptacle can be positioned, in place of the first receptacle, beneath the beverage outlet, wherein the holding system comprises a sensor (8) configured for detecting the position of the holding part between the first position and the second position.
