Solution Overview
Problem
Devices for treating containers in filling plants face challenges such as incorrect filling, contamination risks due to lack of space in isolator chambers, and inefficient CO2 removal, leading to hygiene issues and increased production costs.
Innovation Solution
A device with an isolator chamber and an outlet connected to the floor for discharging fluids, combined with a suction device for extracting gases, allowing for efficient CO2 removal and improved hygiene by eliminating the need for separate suction units and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If containers are diverted from the isolator chamber for incorrect filling, then filling quality is improved, but contamination risk increases due to lack of space and contact with moving parts
Solution Approach 1:
The patent extracts the diverted container removal function from the isolator chamber by providing a separate removal aperture in the container path external to the isolator chamber. This allows incorrectly filled containers to be diverted and removed without compromising the sterile environment inside the isolator chamber, thus resolving the contradiction between filling quality improvement and contamination risk reduction
Solution Approach 2:
The patent introduces an intermediary airlock chamber between the isolator chamber and the external environment where diverted containers can be temporarily held and removed. This intermediary structure allows container removal without direct exposure of the isolator chamber interior to external contamination, resolving the contradiction by providing a buffer zone
2Quantity of substance
If a suction extractor is installed above the container path to remove CO2, then gas extraction is improved, but product aerosols are sucked in and deposited in the lines forming biofilms
Solution Approach 1:
The patent inverts the suction extractor position from above the container path to below the isolator chamber floor level. This inversion changes the suction direction from upward (which draws in aerosols) to downward (which extracts CO2 that settles due to gravity), thus resolving the contradiction between CO2 removal efficiency and biofilm formation prevention
Solution Approach 2:
The patent applies local quality by positioning the suction extractor specifically at the floor level where CO2 accumulates due to its higher density, rather than using a general upward suction above the container path. This localized extraction at the accumulation zone improves CO2 removal while avoiding aerosol intake, resolving the contradiction
3Productivity
If an outlet is opened in the isolator chamber to eject diverted containers, then container removal is improved, but the positive pressure and sterility of the chamber are lost
Solution Approach 1:
The patent segments the container removal function from the isolator chamber by providing a separate removal aperture in the external container path. This segmentation allows container ejection without opening the isolator chamber, thus resolving the contradiction between productivity improvement and sterility maintenance
Solution Approach 2:
The patent creates a functional copy of the container ejection capability in the external path by providing a removal aperture there, eliminating the need to open the isolator chamber for ejection. This copying resolves the contradiction by duplicating the ejection function in a location that doesn't compromise sterility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances workplace safety, reduces manufacturing costs, and extends the time between cleaning cycles by efficiently extracting CO2 and fluids, maintaining a sterile environment while minimizing biofilm formation and contamination.
Implementation Method 1
a suction device for extracting gases from the isolator chamber is connected with the at least one outlet
Implementation Method 2
Because CO2 has a greater molar mass than oxygen and nitrogen, a portion of the CO2 molecules sink downwards due to the effect of gravity
