Solution Overview

Problem

Existing filling plants for pourable products face challenges in minimizing contamination risks during the advancement of bottles within the filling and capping processes, as they often rely on uncontrolled gas flows and environments that can introduce contaminants into the bottles.

Innovation Solution

The filling plant incorporates an isolation chamber with controlled sterile gas atmospheres and isolation channels, along with a conveying system using star wheels with gripping assemblies that ensure bottles are advanced within these channels, maintaining a laminar gas flow and reducing turbulence, thereby minimizing contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bottles are advanced through open conveying paths, then the conveying process is simple, but contamination risk increases

Engineering Contradiction:
Improvecontamination riskVSAvoidconveying system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements nesting by placing bottles inside isolation channels during conveying. The isolation channels are integrated into the conveying system structure, creating a nested configuration where bottles are protected within the channel structure while being transported through the filling plant.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The isolation channel acts as an intermediary protective barrier between the bottles and the external environment. This intermediate structure filters and controls the gas flow around bottles, preventing contaminants from reaching the bottles while allowing the conveying process to continue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If gas flow is uncontrolled, then the system is simpler, but turbulence introduces contaminants into bottles

Engineering Contradiction:
Improvesterility maintenanceVSAvoidgas flow control system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by controlling gas flow parameters (velocity, direction, pressure) within the isolation channels. The gas flow is optimized to maintain laminar flow patterns rather than turbulence, changing the flow parameters to prevent contaminant introduction while protecting bottle sterility.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system replaces uncontrolled mechanical gas flow with a controlled气流 system. By using the isolation channel structure to guide and regulate gas flow, the patent substitutes raw mechanical flow with a controlled atmospheric system that maintains sterility without requiring complex additional mechanical components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If bottles are exposed to ambient atmosphere during conveying, then the conveying process is simpler, but sterility of bottles is compromised

Engineering Contradiction:
Improvebottle sterilityVSAvoidisolation channel structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Bottles are nested within isolation channels during the conveying process. This nested configuration allows bottles to be transported through the filling plant while remaining protected within the isolated atmospheric environment of the channel, preventing exposure to ambient contaminants.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The isolation channels create an inert or controlled atmosphere around bottles during conveying. By maintaining a controlled gas composition and filtering ambient air in the isolation channels, the system creates a protective environment that prevents contamination while allowing bottle transport.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)
