Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container treatment systems face issues with cleaning agents and contamination during the cleaning process, leading to potential corrosion damage in blow molding machines due to the lack of effective shielding between stations.
Innovation Solution
A container treatment system with decoupling options between stations, utilizing movable and adjustable partitioning devices and transfer mechanisms to isolate stations during cleaning, preventing cross-contamination and exposure to cleaning agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning is performed in the filling transfer area, then cleaning effectiveness is improved, but cleaning agents are carried over to the blow molding machine causing corrosion damage
Solution Approach 1:
The system is divided into separate functional areas (blow molding station, filling station, transfer areas) with physically separable connections. The transfer star and its engagement areas can be decoupled to isolate the filling station for cleaning, preventing cleaning agents from reaching the blow molding machine while maintaining cleaning effectiveness in the filling area.
Solution Approach 2:
The transfer star serves as an intermediary element between the blow molding station and filling station. By decoupling the transfer star from the engagement area, a physical barrier is created that prevents the direct transfer of cleaning agents to the blow molding machine, allowing intensive cleaning in the filling area without causing corrosion damage to neighboring stations.
2Object-affected harmful factors
If shielding devices are installed to prevent cleaning agent carryover, then protection from corrosion is improved, but device complexity increases
Solution Approach 1:
Instead of permanent fixed shielding structures, the system uses dynamically configurable decoupling mechanisms. The transfer star can be selectively coupled or decoupled from engagement areas based on operational needs (cleaning vs. production), providing protection from corrosion only when required without the complexity of permanently installed shields.
Solution Approach 2:
The decoupling mechanism serves multiple functions: it acts as a protective barrier during cleaning operations, serves as a normal transport connection during production, and provides flexible configuration for different cleaning scenarios. This multi-functionality eliminates the need for dedicated shielding devices, reducing overall system complexity.
3Productivity
If stations are coupled together for continuous operation, then productivity is improved, but cleaning of individual stations becomes difficult without affecting neighboring stations
Solution Approach 1:
The coupled station system is designed with separable modular connections. The transfer star can be decoupled from specific engagement areas to isolate individual stations for cleaning while maintaining connections between other stations. This allows cleaning of one station without interrupting operations in other stations, preserving overall productivity while enabling effective cleaning.
Solution Approach 2:
The decoupling mechanism allows partial isolation of stations rather than complete system shutdown. Only the specific engagement area requiring cleaning is decoupled, while other parts of the system continue operating. This partial action approach maintains productivity by keeping non-cleaning stations operational while still providing adequate cleaning access to the target station.

AI summary
Container treatment plant (10) with several interconnected stations (12, 14, 16) for container forming, container treatment and/or container filling, which has several rotating, interlocking holding and transfer devices for transporting and conveying the containers in and between its individual stations (12, 14, 16), wherein a transport and transfer connection between at least two adjacent stations (14, 16) can be separated by decoupling at least one of several rotating holding or transfer devices from an engagement area with at least one of the adjacent rotating holding or transfer device.
