Solution Overview

Problem

Existing methods for filling glass bottles with oxygen-sensitive beverages in beverage bottling plants are hindered by the reliance on vacuum pumps for negative pressure, leading to production interruptions when pumps fail, as they require sufficient negative pressure for normal operation.

Innovation Solution

A method and device that determine the parameter of negative pressure in the container, allowing for either normal operation flushing or emergency operation pulse flushing, ensuring continuous filling even with reduced negative pressure by adjusting the flushing protocol based on the parameter, which includes the vacuum pump's status, power consumption, and actual pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vacuum pumps are used to provide negative pressure for container evacuation, then oxygen removal efficiency is improved, but production continuity deteriorates when pumps fail

Engineering Contradiction:
Improveoxygen removal efficiencyVSAvoidproduction continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts the flushing mode based on real-time vacuum degree monitoring. When vacuum pumps are functioning normally, the system operates in normal evacuation mode for efficient oxygen removal. When vacuum degree drops below threshold indicating pump failure, the system automatically switches to emergency pulse flushing mode, maintaining production continuity without manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit continuously monitors the vacuum degree parameter and uses this feedback to determine the appropriate flushing operation mode. This closed-loop control ensures that the system responds appropriately to changing vacuum conditions, automatically selecting normal or emergency flushing based on actual pump performance rather than requiring manual assessment.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If normal evacuation procedure is used, then filling quality is improved, but production stoppage occurs when vacuum pump fails

Engineering Contradiction:
Improvefilling qualityVSAvoidproduction continuity
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The system provides two distinct evacuation procedures that can be dynamically selected: normal evacuation for high-quality filling when pumps are functional, and emergency pulse flushing when pump failure occurs. The control unit automatically selects the appropriate procedure based on monitored vacuum degree, ensuring both filling quality and production continuity are maintained under different operating conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (flushing mode, pulse timing, gas flow rates) based on vacuum degree conditions. Normal evacuation uses continuous vacuum application with standard flushing parameters, while emergency pulse flushing uses pulsed gas introduction with adjusted timing and flow rates, allowing the system to adapt to degraded vacuum conditions while maintaining acceptable filling quality.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple evacuation and rinsing loops are performed, then residual oxygen content is reduced, but processing time increases

Engineering Contradiction:
Improveoxygen removal effectivenessVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The emergency pulse flushing mode employs periodic gas pulses instead of continuous flushing. The control unit introduces purge gas in multiple discrete pulses with specific timing intervals, achieving effective oxygen removal through repeated exposure cycles. This periodic action is more time-efficient than traditional multiple evacuation-rinsing loops while maintaining oxygen removal effectiveness under emergency conditions.

Inventive Principle:
Principle #19Periodic action
