Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container treatment machines face hygiene and contamination issues due to liquid leakage or splashing, particularly in sterile environments, which can lead to hygienic and optical problems.
Innovation Solution
A device with a clean room separated from non-sterile surroundings by inclined walls, allowing liquid to drain out and featuring a rotatable carrier with multiple treatment stations, a discharge device, and a gas blocking mechanism to prevent contamination, along with a collection system for automatic cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clean room is used for sterile container treatment, then contamination is prevented, but liquid leakage or splashing can still cause hygienic and optical problems
Solution Approach 1:
The patent converts the harmful liquid leakage or splashing into a beneficial drainage flow by designing inclined walls that guide liquid residues to collection points. The harmful liquid that leaks or splashes during container treatment is now systematically collected and removed, transforming the contamination problem into a controlled drainage solution that maintains clean room hygiene.
Solution Approach 2:
The patent introduces inclined walls as an intermediary element between the liquid leakage source and the clean room environment. These walls act as mediators that intercept and redirect liquid flows, preventing direct contamination of the clean room while channeling residues to designated collection points for removal.
2Reliability
If cleaning medium is used to clean containers, then hygiene is improved, but the cleaning medium can splash and cause contamination
Solution Approach 1:
The patent converts the harmful splashing of cleaning medium into a beneficial controlled flow by using inclined walls to guide the cleaning liquid and residues to collection points. The splashing that would normally cause contamination is transformed into a directed drainage flow that is systematically collected and removed from the clean room.
Solution Approach 2:
The inclined walls serve as intermediary structures that intercept cleaning medium during the cleaning process. These walls redirect the cleaning liquid and any splashes toward collection points, preventing the cleaning medium from contaminating the clean room environment while maintaining effective cleaning functionality.
3Productivity
If treatment stations are arranged on a rotatable carrier, then productivity is increased, but liquid can collect in the blow molding and mold filling stations
Solution Approach 1:
The patent converts the harmful liquid accumulation in treatment stations into a beneficial drainage flow by equipping stations with inclined walls that guide liquid residues to collection points. The liquid that accumulates during high-speed container treatment is now systematically drained and removed, transforming the accumulation problem into a controlled drainage solution that maintains hygiene during productive operation.
4Reliability
If the clean room is essentially closed off, then sterility is maintained, but liquid residues have no drainage path
Solution Approach 1:
The patent introduces inclined walls with integrated drainage paths as intermediary structures within the closed clean room. These walls create controlled drainage channels that guide liquid residues to collection points while maintaining the essential closure of the clean room environment. The drainage system operates within the sealed space, allowing liquid removal without compromising sterility.
Solution Approach 2:
The patent adds a vertical dimension to liquid drainage by using inclined walls that guide liquid flow downward to collection points. This dimensional approach allows liquid residues to be drained along the wall surfaces and collected at lower positions, providing drainage capability within the constrained three-dimensional space of the closed clean room without creating openings.
