Solution Overview

Problem

Existing container filling systems face inefficiencies in cleaning processes, particularly due to the recirculation of cleaning agents through complex routes, which can lead to contamination and operational challenges.

Innovation Solution

The system allows the cleaning medium to exit freely from filling elements during the cleaning operation, directing it into a clean room where it can be collected and managed, eliminating recirculation and reducing contamination risks, while also incorporating a liquid guide device to control the flow and a separating device for gases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cleaning medium is recirculated through complex routes via CIP cap, then the cleaning agent can be reused and cleaning coverage is improved, but the system complexity increases and contamination risk rises

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the cleaning medium from the recirculation system and allows it to exit freely from the filling element into the clean room. This eliminates the complex recirculation routes (CIP cap, media distributor) while maintaining cleaning effectiveness through direct application and controlled discharge into the sterile environment.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of substance

If the cleaning medium is recirculated through complex routes, then cleaning agent utilization is improved, but contamination risk increases

Engineering Contradiction:
Improvecleaning agent utilizationVSAvoidcontamination risk
Core Design Contradiction:
Loss of substanceVSObject-affected harmful factors

Solution Approach 1:

Instead of recirculating the cleaning medium through complex routes where contamination can occur, the patent converts the potential harm of cleaning agent discharge into a benefit by allowing controlled free exit into the clean room. The cleaning medium performs its cleaning function and then safely exits into the sterile environment, eliminating contamination risks associated with recirculation while maintaining efficient utilization.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If the cleaning medium exits freely from filling element, then system complexity is reduced and contamination is minimized, but collection and management becomes more challenging

Engineering Contradiction:
Improvecleaning system complexityVSAvoidcleaning medium management
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The clean room acts as an intermediary space that receives the freely exiting cleaning medium from the filling element. This intermediary environment provides a controlled setting for the cleaning medium to discharge while facilitating easy collection and management through the clean room's existing infrastructure, thus resolving the contradiction between simplified system design and operational ease.

Inventive Principle:
Principle #24Intermediary (Mediator)
