Solution Overview

Problem

Existing beverage preparation machines face challenges in efficiently handling and stabilizing removable units with varying geometries and balances, particularly in supporting service units that need to transition between different stability positions for storage and operation.

Innovation Solution

The machine incorporates a service unit with a foot part and a recipient part that can adjust between two stable positions, using a combination of gravity, biasing elements, and mechanical resistance to ensure stability and balance, and includes a removable auxiliary recipient for collecting liquids and solids, with a fastening mechanism for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the service unit is designed to be removable for easy handling and cleaning, then ease of operation is improved, but stability and balance during operation may deteriorate

Engineering Contradiction:
Improveease of handlingVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The service unit incorporates a movable recipient part that can transition between different stable positions (first stable position for removal/cleaning and second stable position for operation), allowing the structure to adapt its configuration based on operational needs while maintaining stability in each state

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The foot part is designed with specific geometric characteristics and weight distribution to counterbalance the recipient part, creating overall stability when the service unit is in its operational position while still allowing easy removal when needed

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Adaptability or versatility

If the recipient part is made movable between different positions, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The recipient part is designed to be movable relative to the foot part, enabling it to transition between a first stable position (facilitating removal and cleaning) and a second stable position (for operational use), thus providing adaptability without requiring complex active control mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The service unit utilizes gravity and its own weight distribution to automatically maintain stable positions during movement, eliminating the need for external actuators or complex control systems to manage the transitions between operational and removal states

Inventive Principle:
Principle #25Self-service

3Reliability

If the service unit is optimized for stable operation in the machine, then reliability is improved, but ease of removal for cleaning deteriorates

Engineering Contradiction:
ImprovereliabilityVSAvoidease of removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The service unit is designed with movable components that allow it to transition between operational and removal states, with the recipient part able to move relative to the foot part to facilitate easy removal while maintaining stable operation when in place

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The service unit is divided into distinct segments (foot part and recipient part) that can move independently, allowing the recipient part to be easily removed for cleaning while the foot part remains stable in the machine during operation

Inventive Principle:
Principle #1Segmentation

AI summary

A machine (1) for preparing a beverage has: a body (1') comprising a seat (4) and a beverage processing line (1'', 1''') extending from a liquid inlet (1'') to a beverage dispenser (1'''); and a service unit (10) that is removably received in or on the seat (4) and that comprises a foot part (11) and a recipient part (12) removably received in or on the foot part (11) so as to be supported thereby. The foot part (11) has a bottom face (11') configured to rest on an external horizontal support surface (100) when the service unit (10) is removed from the seat (4). When the recipient part (12) is received in or on the foot part (11), the recipient part (12) is movable relative to the foot part (11) from a first stable position when the service unit (10) rests on the external horizontal support surface (100) to a second stable position when the service unit (10) is received in or on the seat (4), and vice versa.
