Solution Overview

Problem

Existing beverage preparation devices, such as coffee machines, face challenges in ensuring secure and hygienic supply container management, particularly in public environments, where unauthorized access and ingredient contamination are concerns, and require adjustable dispensing heights to accommodate various holder sizes.

Innovation Solution

The device features a removable supply container with a pivotable handle and integrated closing means that prevent spillage and unauthorized removal, along with a sliding cover mechanism for easy refilling, and an adjustable dispensing body with dual spouts to enhance beverage quality and prevent cross-contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the supply container is made removable for easy refilling, then ease of operation is improved, but security against unauthorized removal and contamination deteriorates

Engineering Contradiction:
Improveease of refillingVSAvoidsecurity against unauthorized removal
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The closing means are automatically activated when the supply container is removed from the device housing. The closing means extend from the arm assembly to close the outflow opening before the container can be fully removed, preventing spillage and unauthorized access during the refilling process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The supply container system is divided into functional components: the container body, the arm assembly with handle, and the closing means. This segmentation allows the closing means to operate independently to secure the outflow opening while the handle enables easy removal and reattachment

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the closing means are integrated into the arm assembly, then device complexity is reduced, but manufacturing precision requirements increase

Engineering Contradiction:
Improvestructural complexityVSAvoidpivot alignment precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The closing means are integrated into the arm assembly as a single unit. The closing means extend from the second arm of the arm assembly and are positioned to close the outflow opening when the handle is in the removed position, eliminating the need for separate closing mechanisms and reducing overall structural complexity

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the handle is positioned inside the supply container, then security against unauthorized access is improved, but ease of operation for refilling deteriorates

Engineering Contradiction:
Improvesecurity against unauthorized accessVSAvoidease of refilling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The handle is designed to pivot between two positions: inside the supply container during normal operation (providing security) and outside the supply container during refilling (providing ease of operation). This dynamic repositioning allows the same structure to serve both security and operational requirements

Inventive Principle:
Principle #15Dynamics

AI summary

A device for preparing a beverage comprises a device housing (2) which is closable with a device door (4) which can be manipulated between a closed position and an open position. The device housing accommodates a supply container (10..12) for an ingredient of the beverage to be prepared which is provided with dosing means for drawing off a controlled quantity therefrom. The supply container protrudes outside the device housing and is closable with a cover (15). The cover and the device door are provided with mutual locking means (13) which lock the cover on the supply container in the closed position of the device door, wherein in the open position of the device door the cover (15) is releasable from the supply container (10..12) in order to leave the filling side (16) thereof at least partially clear.
