Solution Overview

Problem

Current refrigeration appliances with beverage dispensing devices face difficulties in securely mounting and positioning the actuator element due to its complex positioning and the need for precision, which increases manufacturing costs and discomfort during assembly, often requiring specialized tools.

Innovation Solution

The introduction of a coupling element with a 'ladder-like' shape that facilitates precise and accurate mounting of the actuator element to the refrigeration appliance's structure without the need for specialized tools, allowing for easier assembly and reduced resource waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the actuator element is securely mounted to the structure with high precision, then the beverage dispensing function is reliable, but the assembly process becomes complex and requires specialized tools

Engineering Contradiction:
Improvesecure mounting of actuator elementVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A coupling element is introduced as an intermediary component between the actuator element and the structure. This coupling element features a first end with connection means for the actuator element and a second end with connection means for the structure, thereby simplifying the assembly process while maintaining secure mounting and high precision positioning.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If the actuator element is positioned with high precision, then the valve operation is accurate, but the manufacturing cost increases

Engineering Contradiction:
Improvepositioning accuracy of actuator elementVSAvoidmanufacturing cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The coupling element is designed with pre-formed connection means at its first end for the actuator element and at its second end for the structure. This preliminary preparation of connection interfaces enables high precision positioning to be achieved through simple assembly operations rather than complex positioning procedures, thereby reducing manufacturing costs while maintaining positioning accuracy.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the actuator element is mounted from the outside of the structure, then the assembly is accessible, but the visibility and room for operation are limited

Engineering Contradiction:
Improveaccessibility of assemblyVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mounting system is segmented into three separate components: the actuator element, the coupling element, and the structure. This segmentation allows each component to be independently prepared and then assembled together from the outside of the structure, maintaining accessibility while reducing assembly time through modular construction.

Inventive Principle:
Principle #1Segmentation
