Solution Overview

Problem

Existing beverage makers require significant manual effort and are not hygienic due to the need to open the door to change the liquid container, which is also not visually accessible for fill level checks, leading to inefficiencies and potential spills.

Innovation Solution

A beverage maker with a receiving device integrated into the front side of the door allows for easy insertion and removal of a liquid container using a coupling mechanism, such as a guide groove or magnetic connection, eliminating the need to open the door and reducing manual effort, while enabling visual fill level checks and improving hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the liquid container is placed inside the door requiring door opening for access, then the beverage maker structure is compact, but the ease of operation deteriorates due to the need to open and close the door frequently

Engineering Contradiction:
Improveease of liquid container exchangeVSAvoidtime for door opening and closing
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The liquid container is moved from an interior position (requiring door opening) to an exterior position on the front side of the door, accessible from the front dimension. This dimensional repositioning allows direct access without door manipulation, resolving the contradiction between compact structure and ease of operation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The liquid container is extracted from the interior space behind the door and repositioned on the exterior front surface of the door. This extraction eliminates the need to open the door for access, significantly improving ease of operation while reducing time loss from repeated door opening and closing.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the liquid container is placed inside the door, then the beverage maker has a clean exterior, but the ease of operation worsens and hygiene deteriorates due to difficult access for cleaning and container exchange

Engineering Contradiction:
Improveease of cleaning accessVSAvoidhygiene risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The liquid container is repositioned from an interior location to an exterior location on the front surface of the door. This dimensional change makes the container and its connection points directly accessible from the front, enabling easy cleaning and container exchange without disassembling internal components, thereby improving hygiene conditions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The liquid container and its coupling mechanism are extracted from the interior and placed on the exterior front surface. This extraction allows direct access for cleaning operations and container replacement, eliminating the hygiene risks associated with difficult-to-reach interior components.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If a hose connection is used for liquid supply, then the liquid container can be positioned flexibly, but the device complexity increases and hygiene deteriorates due to hose cleaning requirements

Engineering Contradiction:
Improveliquid container positioning flexibilityVSAvoidhose connection system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hose connection is extracted and replaced with a direct coupling mechanism integrated into the receiving device on the door. This eliminates the need for separate hoses, reducing device complexity while maintaining positioning flexibility through the coupling-receiving device interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling mechanism on the liquid container and the receiving device on the door are merged into an integrated connection system. This combination eliminates the need for separate hoses, simplifying the overall structure while maintaining the flexibility to position and exchange containers easily.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If the liquid container is not visible from the outside, then the beverage maker has a simpler structure, but the ease of operation worsens due to inability to check fill level visually

Engineering Contradiction:
Improvefill level visibilityVSAvoidcontainer visibility structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The liquid container is repositioned from an interior location to an exterior location on the front surface of the door. This dimensional repositioning makes the container visible from the front, enabling visual fill level checks without adding complex transparent structures or internal viewing mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
