Solution Overview

Problem

In beverage bottling plants, hot filling products are often subjected to prolonged high temperatures and mechanical stress, leading to deterioration of flavors and increased temperature stress on dosage products during production interruptions, which affects their sterilization efficiency and quality.

Innovation Solution

A device and method where the main component is heated separately and kept at sterilization temperature, while the dosage product is not heated until just before filling, ensuring minimal exposure to sterilization temperature and reducing mechanical stress by circulating only the heated main component during pauses, and using a sterilization device to adjust heat output based on mixing ratios and properties to achieve the target temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the filling product is kept at sterilization temperature during production interruptions, then the sterilization temperature is maintained for efficient sterilization, but the dosage product deteriorates due to prolonged exposure to high temperature

Engineering Contradiction:
Improvesterilization efficiencyVSAvoidtemperature stress on dosage product
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system separates the heating and sterilization functions: the main component is heated to sterilization temperature and circulated during interruptions, while the dosage product remains unheated until the actual filling process. This segmentation allows the heated main component to maintain sterilization temperature for reliability while protecting the dosage product from temperature stress.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heated main component acts as an intermediary that provides the necessary sterilization temperature without directly heating the dosage product. The main component is circulated through the system during interruptions, maintaining temperature for sterilization efficiency, while the dosage product is only introduced into the heated environment during the actual filling operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the filling product is pumped through the heating device during production interruptions, then the sterilization temperature is maintained, but mechanical stress damages the dosage product properties

Engineering Contradiction:
Improvetemperature maintenanceVSAvoidmechanical stress on dosage product
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The circulation system is segmented to pump only the main component through the heating device during production interruptions, excluding the dosage product from this mechanical circulation. This ensures temperature maintenance for sterilization reliability while eliminating mechanical stress damage to the dosage product.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main component serves as an intermediary substance that undergoes the mechanical circulation and heating process during interruptions, maintaining system temperature without subjecting the dosage product to mechanical stress. The dosage product is only introduced later during actual filling when no prolonged pumping occurs.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If both main component and dosage product are heated together, then sterilization is achieved, but the dosage product loses its flavor properties due to prolonged high temperature exposure

Engineering Contradiction:
Improvesterilization completenessVSAvoidflavor deterioration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The main component is preliminarily heated to sterilization temperature and kept ready in the heating device before the actual filling process. The dosage product is introduced only at the moment of filling, ensuring it is exposed to high temperature only for the brief sterilization period needed for completeness, rather than prolonged exposure that would cause flavor deterioration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The main component acts as a thermal intermediary that is heated in advance and used to transfer heat during the brief filling operation. This allows the dosage product to receive necessary sterilization heat exposure without prolonged high temperature contact that would deteriorate its flavor properties.

Inventive Principle:
Principle #24Intermediary (Mediator)
