Solution Overview

Problem

Existing aroma substance dispensing devices require manual and often irregular cleaning, which is costly and prone to operating errors, due to the need for manual removal and reconnection of suction hoses and lack of automation in the cleaning process.

Innovation Solution

The device incorporates connecting pieces with check valves and self-closing quick-release couplings on suction lines, allowing for easy detachment and reconnection without fluid leakage, and an automated cleaning system using a cleaning agent supply line and peristaltic pumps for sequential cleaning and rinsing, ensuring thorough and efficient cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning is used for aroma substance dispensing devices, then operational flexibility is maintained, but cleaning regularity and reliability deteriorate

Engineering Contradiction:
Improvecleaning regularityVSAvoidmanual operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device enables self-service cleaning by automatically connecting cleaning hoses to cleaning outlets through check valves and quick-release couplings, eliminating the need for manual intervention in the cleaning process while ensuring regular maintenance

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Check valves act as intermediaries between the aroma substance lines and cleaning lines, automatically directing fluid flow to the appropriate path and enabling reliable automated cleaning without manual operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If suction hoses are permanently connected to aroma containers, then connection reliability is improved, but cleaning accessibility deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcleaning accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically switches between operational mode (aroma substance flow) and cleaning mode (cleaning solution flow) using check valves and quick-release couplings, allowing the connection to serve dual purposes without compromising reliability or accessibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection system is segmented into modular components (quick-release couplings, check valves, separate cleaning outlets) that can be independently activated for cleaning while maintaining the primary aroma substance delivery function

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If quick-release couplings are used for suction hoses, then cleaning accessibility is improved, but fluid leakage risk increases

Engineering Contradiction:
Improvecleaning accessibilityVSAvoidfluid leakage
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

Check valves serve as intermediaries between the quick-release couplings and the fluid lines, automatically closing to prevent leakage when cleaning hoses are disconnected while allowing free flow during cleaning operations

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The check valves provide preliminary prevention against fluid leakage by automatically closing before any leakage can occur when quick-release couplings are disconnected, eliminating the harmful effect before it manifests

Inventive Principle:
Principle #9Preliminary anti-action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution enables simplified and automated regular cleaning of aroma substance dispensing devices, reducing operational errors and costs by preventing fluid leakage and ensuring complete cleaning cycles through controlled pumping and rinsing processes.

Implementation Method 1

The pumps are conveniently designed as hose pumps. Hose pumps are also frequently referred to as peristaltic pumps.

Methodology Applied
Scientific EffectPeristalsis: Peristalsis

Implementation Method 2

due to the spring force with which a closing element of the check valves is held in the closed position, prevent cleaning agent solution from leaking out

Methodology Applied
Scientific EffectSpring force: Spring

Implementation Method 3

a valve integrated into the coupling closes when the coupling is removed from its counterpart, thus preventing fluid from dripping out of the suction line

Methodology Applied
Scientific EffectSpring force: Spring
