Solution Overview

Problem

During the filling of beverage bottles, particularly oxygen-sensitive drinks, damaged bottles can break during prestressing, leading to glass splinters and contaminants being drawn into the filling device's evacuation and relief channels, causing damage and potential contamination of subsequent bottles.

Innovation Solution

Implementing a dual filling mode system where regular bottles are filled using a first mode involving evacuation, flushing, prestressing, and controlled relief, while bottles following a defect are filled using a second mode that excludes evacuation and controlled relief, utilizing only volume flows to flush out contaminants and prevent their entry into the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If evacuation and controlled relief are performed during regular filling, then filling quality and oxygen removal are improved, but glass splinters and contaminants from broken bottles can be drawn into the device channels

Engineering Contradiction:
Improvefilling qualityVSAvoidcontaminant ingress
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically switches between two filling modes based on detected bottle defects. In normal mode, evacuation and controlled relief are performed for quality filling. Upon detecting a broken bottle, the system transitions to safety mode where these operations are suppressed, preventing contaminant ingress while maintaining operational continuity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit receives feedback about bottle integrity (through detection of broken bottles during prestressing) and adjusts the filling process accordingly. When defects are detected, the control unit suppresses evacuation and controlled relief operations, creating a feedback loop that prioritizes device safety over filling quality

Inventive Principle:
Principle #23Feedback

2Productivity

If the filling element continues operation after a bottle break, then productivity is maintained, but contaminants can damage valve seats and compromise subsequent bottles

Engineering Contradiction:
Improvecontinuous operationVSAvoiddevice integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The filling process is segmented into distinct operational phases: normal filling mode and safety mode. The control unit divides the operation based on defect detection, allowing the system to maintain productivity through continuous operation while isolating contaminant risks through mode segmentation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system converts the harmful event of a broken bottle into a beneficial safety mechanism. By detecting the break and automatically suppressing evacuation and relief operations, the system uses the defect detection to trigger protective measures that prevent broader contamination, turning a potential disaster into a controlled safety response

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

AI summary

The liquid filling method involves operating filling element (10) in a filling mode, for regular filling of the container (G) with the liquid (F). The filling element is operated according to the defect of the container in a machine cycle at the next filling mode. The container is biased before loading liquid in container. The container is compressed after filling liquid in container. The container is rinsed using the flushing gas. An independent claim is included for device for filling liquid in container.
