Solution Overview

Problem

Container treatment machines face challenges in efficiently cleaning and removing cleaning agent residues from complex nozzle systems, especially in isolators, which are difficult to maintain and require extensive space and resources.

Innovation Solution

A device with a closure element having spray openings that deflect cleaning medium from the media discharge opening to surrounding system areas, allowing for controlled CIP cleaning of internal channels and simultaneous external cleaning of isolator walls, using a valve to switch between conventional CIP and additional cleaning modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex nozzle systems are used to clean all surfaces within the container treatment machine, then cleaning coverage is improved, but device complexity and maintenance difficulty increase

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

Solution Approach 1:

The invention combines the closure element with integrated spray openings directly at the filling valve outlet with the CIP cleaning system. This merging eliminates the need for separate complex nozzle systems distributed throughout the isolator, as the closure element itself becomes the cleaning device, spraying cleaning medium onto surrounding surfaces including isolator walls.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The closure element serves multiple functions: it closes the filling valve outlet during CIP cleaning, generates spray patterns for cleaning surrounding areas, and can be positioned to clean different surfaces. This multi-functionality replaces multiple specialized cleaning components with a single versatile device.

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

2Reliability

If nozzle systems are distributed in the isolator to clean inside walls, then cleaning effectiveness is improved, but space requirements and maintenance effort increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmaintenance effort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the cleaning function from distributed nozzle systems and concentrates it at the filling valve outlet location. The closure element with its spray openings performs all necessary cleaning tasks from a single location, eliminating the need for multiple nozzles distributed throughout the isolator space.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The CIP cleaning system uses its own cleaning medium to clean both the internal channels and the surrounding surfaces including isolator walls. The cleaning medium flows through the product channels, exits at the closing element, and sprays onto surrounding areas, allowing the system to clean itself without requiring separate cleaning infrastructure.

Inventive Principle:
Principle #25Self-service

3Productivity

If the filling valve outlet is left open during CIP cleaning, then productivity is maintained, but cleaning medium escapes and contaminates surrounding areas requiring additional cleaning

Engineering Contradiction:
Improveoperational continuityVSAvoidcleaning medium contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The invention merges the valve closure function with the cleaning medium distribution function in the closure element. The same component that closes the outlet also contains the spray openings that direct cleaning medium onto surrounding surfaces, preventing uncontrolled escape while enabling controlled cleaning.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If spray openings are added to the closure element, then external cleaning capability is improved, but device complexity increases

Engineering Contradiction:
Improvecleaning capabilityVSAvoidclosure element complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The closure element is designed to perform multiple functions: closing the filling valve outlet, directing cleaning medium through spray openings onto surrounding surfaces, and potentially positioning itself to clean different areas. This multi-functionality is achieved by integrating these capabilities into a single component rather than adding separate devices.

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