Solution Overview

Problem

Existing container centering methods in beverage bottling plants require complex actuator systems and are prone to contamination due to foaming and spills, necessitating a more efficient and reliable centering solution.

Innovation Solution

A device with a centering section and guide section that passively centers containers as they are lifted into a treatment area, using the lifting force to align the container within a treatment chamber, eliminating the need for actuators like cam control and minimizing the treatment angle and maintenance efforts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional centering ring with cam control actuator is used, then the container can be centered during lifting, but the device complexity increases and maintenance effort increases

Engineering Contradiction:
Improvecontainer centering precisionVSAvoidactuator system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the complex cam control actuator system from the centering mechanism. Instead of using an active actuator to move the centering ring, the patent uses a passive centering section that is pushed upward by the container itself during the lifting stroke, thereby removing the need for separate actuation components and simplifying the overall device structure while maintaining centering precision

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The centering section performs self-service by being automatically positioned through the force exerted by the container during lifting. The container's upward movement directly pushes the centering section into its operational position, eliminating the need for external actuators and reducing both device complexity and maintenance requirements while achieving precise centering

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If a conventional centering ring is used, then the container can be centered, but contamination risk increases due to foaming and spills

Engineering Contradiction:
Improvecontainer centering precisionVSAvoidcontamination risk
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the centering function from the conventional centering ring that is exposed to the filling zone. By relocating the centering section to a position that is pushed up during lifting and is not in the path of foaming or spills, the contamination risk is eliminated while centering precision is maintained through the guide section's defined trajectory

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The guide section acts as an intermediary that transfers the container's upward movement to the centering section while constraining it to a defined trajectory. This intermediary mechanism ensures precise centering without exposing the centering components to contamination from foaming or spills in the filling area

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If a conventional centering ring with full stroke is used, then the container can be centered, but the treatment angle increases and the system becomes less compact

Engineering Contradiction:
Improvecontainer centering precisionVSAvoidtreatment cycle efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The centering section performs its centering action preliminarily during the lifting stroke itself, before the container enters the treatment zone. By using the lifting movement to simultaneously position both the container and the centering section, the treatment angle is reduced and the system becomes more compact, improving overall productivity without sacrificing centering precision

Inventive Principle:
Principle #10Preliminary action
