Solution Overview

Problem

Existing filling systems on assembly lines face challenges in maintaining functional safety and efficiency when multiple consoles are operated simultaneously, leading to issues with process quality and speed, as well as interference between separate consoles.

Innovation Solution

The solution involves relocating essential process steps such as pressure testing, evacuation, and vacuum pump protection to a console with integrated assemblies like a separator, vacuum pump, and control assemblies, allowing the basic unit to focus solely on media supply, thereby making each console functionally self-sufficient and reducing inter-console interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple consoles are operated simultaneously in existing filling systems, then filling capacity is increased, but functional safety and process quality deteriorate due to inter-console interference

Engineering Contradiction:
Improvefilling capacityVSAvoidfunctional safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system is segmented into independent console units, each with its own vacuum pump and control assemblies. This segmentation allows multiple consoles to operate simultaneously without interfering with each other, as each console is a self-contained system that maintains its own vacuum environment and control processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vacuum pump and separator are integrated into the console before the filling operation begins. This preliminary arrangement ensures that each console is pre-prepared with its own vacuum generation capability, eliminating the need for shared vacuum resources and preventing inter-console interference during simultaneous operations.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If process steps are distributed between base unit and console, then system complexity is reduced, but process quality and filling speed depend on line lengths and system design

Engineering Contradiction:
Improvesystem structureVSAvoidfilling speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The vacuum pump and separator are extracted from the base unit and relocated to the console. This extraction allows the console to perform vacuum-related operations independently, eliminating dependence on line lengths and base unit configuration, thereby improving filling speed and process quality while maintaining manageable system complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The separator acts as an intermediary component between the vacuum pump and the filling process. It is integrated into the console to mediate the vacuum generation and transmission, ensuring that vacuum pressure is maintained independently of base unit distance and configuration, thus improving filling performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If vacuum pump protection steps are distributed across multiple consoles, then each console requires its own vacuum pump, but system complexity and cost increase

Engineering Contradiction:
Improvevacuum pump protectionVSAvoidnumber of vacuum pumps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The vacuum pump and separator are merged into a single integrated console unit. This combination ensures that each console has its own dedicated vacuum pump for protection and operation, while the separator consolidates the vacuum management function. This approach maintains reliable vacuum pump protection without requiring separate vacuum pumps for each console, as the integrated design optimizes resource utilization.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If essential process steps are relocated to the console, then each console becomes functionally self-sufficient, but console complexity increases

Engineering Contradiction:
Improvefunctional independenceVSAvoidconsole structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The console is designed as a universal, multi-functional unit that integrates the filling adapter, separator, vacuum pump, and control assemblies. This multi-functionality allows the console to perform all essential filling operations independently, making it adaptable to different filling requirements while managing complexity through standardized integration of components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
