Solution Overview

Problem

Existing beverage dispensers lack a reliable locking mechanism that prevents unauthorized access while allowing authorized access, and generate disturbing vibrations or oscillations due to stirring or cooling devices.

Innovation Solution

A beverage dispenser with a locking device that includes a displaceable locking mechanism inhibited by a blocking device, and a damping device to reduce vibrations, featuring a securing device that secures the blocking device in a locking position, and a spring element to facilitate authorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking device is added to prevent unauthorized access, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blocking device is integrated within the locking device structure, where the blocking element is received in a receptacle formed in the locking device. This nesting approach allows the blocking function to be incorporated without adding a completely separate mechanism, thus improving security while minimizing the increase in overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The locking device serves multiple functions: it provides the primary locking mechanism to prevent unauthorized access, and it incorporates the blocking device that can inhibit the locking mechanism itself. This multi-functionality allows a single component to address both security enhancement and controlled accessibility, reducing the need for additional separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a blocking device is added to inhibit the locking mechanism, then access control is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The blocking device is nested within the locking device structure, with the blocking element received in a receptacle formed in the locking device. This integration allows the blocking function to be added without creating a completely separate mechanism, thus improving access control while minimizing the increase in overall device complexity.

Inventive Principle:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The damping device is combined with the locking device structure, where the damping element is integrated into the same assembly that houses the blocking device. This merging approach allows vibration damping functionality to be added without creating a completely separate system, thus reducing noise while minimizing the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A beverage dispenser is proposed, comprising a receptacle (10) for a beverage, a receptacle (10) for the beverage, and a cover (20). In the closed position, the cover (20) can be engaged with an overlapping section (21) over the receptacle (10) or its edge section (11, 12). This invention aims to securely lock the beverage dispenser and dampen, ideally eliminate, vibrations or oscillations. A locking device (30) is mounted in the overlapping section (21) and is displaceable relative to it. The displaceability of the locking device (30) relative to the overlapping section (21) is restricted by a blocking device (40) arranged in the cover (20) when the blocking device (40) is in a locking position. A securing device (60) is provided to secure the blocking device (40) in the locking position, for example, by clamping.
