Solution Overview

Problem

Maintaining sterility in large aseptic filling rooms is challenging, leading to prolonged downtime and potential secondary contamination when sterility is lost, as the entire room must be restored before resuming the filling process.

Innovation Solution

A method and device for aseptic filling that minimizes the sterile space required by only bringing the container's mouth area into a smaller, dedicated sterile room, allowing for efficient and safe filling while maintaining sterility, and enabling individual sterile rooms to be serviced separately if issues arise, thus preventing complete machine shutdown.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large sterile room is used for filling containers, then sterility can be maintained for multiple containers, but the time required to restore sterility after contamination increases and productivity decreases

Engineering Contradiction:
Improvesterility maintenanceVSAvoidfilling continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent divides the filling system into multiple independent sterile chambers, each capable of filling one or more containers. If one chamber becomes contaminated, only that specific chamber needs to be sterilized while others continue operating. This segmentation transforms a single large sterile room into multiple smaller independent sterile units, resolving the contradiction between maintaining sterility and preserving productivity during contamination events.

Inventive Principle:
Principle #1Segmentation

2Productivity

If a large sterile room is used for filling containers, then multiple containers can be filled, but the volume of sterile space required increases

Engineering Contradiction:
Improvenumber of containers filledVSAvoidsterile room volume
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The patent transitions from a single large three-dimensional sterile room to multiple smaller sterile chambers arranged in a multi-dimensional configuration. This allows the system to maintain high productivity by having multiple filling stations while reducing the volume of each individual sterile space. The sterile chambers can be arranged vertically or in compact configurations, effectively utilizing space in additional dimensions rather than requiring a single large volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the entire sterile room must be sterilized after contamination, then sterility is restored, but the time required for restoration increases

Engineering Contradiction:
Improvesterility restorationVSAvoiddowntime for sterilization
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the sterile environment into multiple independent chambers, each with its own sterilization capability. When contamination occurs in one chamber, only that specific chamber undergoes sterilization while other chambers remain operational. This eliminates the need to shut down the entire filling operation for sterilization, dramatically reducing downtime and maintaining productivity while ensuring sterility restoration where needed.

Inventive Principle:
Principle #1Segmentation

4Volume of stationary object

If a smaller sterile chamber is used for each container, then the volume of sterile space is reduced, but the complexity of managing multiple sterile chambers increases

Engineering Contradiction:
Improvesterile chamber volumeVSAvoidnumber of sterile chambers
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent combines multiple sterile chambers into a single integrated filling machine structure with shared control systems, sterilization infrastructure, and container handling mechanisms. While multiple sterile chambers are used to reduce individual volume requirements and maintain productivity during contamination, they are merged into a unified system that manages the complexity through common automation and control architecture, preventing the complexity from becoming prohibitive.

Inventive Principle:
Principle #5Merging (Combining)
