Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Alpha-beta port systems face challenges in securely and efficiently transferring materials between containers while maintaining sterility and minimizing contamination, particularly in connecting the beta container to the alpha port system.
Innovation Solution
A beta container with a flexible or rigid sheath, a flange part having bayonet locking interfaces, and an elastic bellows for secure and quick attachment, along with an RFID transponder for improved handling and logistics, and seals for enhanced protection and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a beta container uses a traditional connection method to the alpha port system, then the connection can be established, but the attachment process is time-consuming and lacks security
Solution Approach 1:
The connection system is segmented into a male connection element on the alpha port and a female connection element on the beta container, each with specific geometric features (protrusions and recesses) that enable quick and secure mating. This segmentation allows for standardized, rapid connection without complex alignment procedures.
Solution Approach 2:
A connection element acts as an intermediary mechanism between the alpha port and beta container, providing a standardized interface that facilitates quick attachment while ensuring secure mechanical engagement. The connection element includes guiding features that automatically align components during attachment.
2Strength
If the beta container uses a rigid structure for the sheath, then the contents are protected, but the handling and flexibility are reduced
Solution Approach 1:
The beta container employs different structural qualities in different regions: the sheath is made flexible for ease of handling and insertion, while the flange part is made rigid to provide structural support and secure connection to the alpha port. This local differentiation of material properties optimizes both protection and handling.
Solution Approach 2:
The beta container is constructed as a composite structure combining flexible sheath material (such as plastic or rubber) with a rigid flange part (made of sturdy material). This composite construction allows the flexible portion to facilitate handling while the rigid portion ensures structural integrity and connection stability.
3Device complexity
If the beta container uses a simple opening for material transfer, then the structure is simple, but contamination risk increases
Solution Approach 1:
A bellows structure acts as an intermediary sealing mechanism between the sterile and non-sterile environments. The bellows can be compressed to seal the through-opening during connection, preventing contamination while allowing material transfer through the flange part. This adds minimal complexity while significantly reducing contamination risk.
Solution Approach 2:
The bellows is constructed as a flexible sealing element that can deform to maintain the seal during connection and material transfer operations. This flexible membrane structure provides effective contamination barrier while accommodating the mechanical movements required for operation.
4Reliability
If the beta container uses traditional sealing methods, then the connection can be sealed, but the tightness and sterility protection are insufficient
Solution Approach 1:
A bellows structure is integrated into the flange part as a flexible sealing element. This bellows can be compressed by the beta cover to create a tight seal at the through-opening, providing reliable sterility protection. The flexible nature of the bellows allows it to conform to slight variations in alignment while maintaining seal integrity.
Solution Approach 2:
The sealing system is designed to be dynamic rather than static: the bellows can compress and expand, and the seal is activated when the beta cover is attached. This dynamic sealing mechanism provides reliable sterility protection while adapting to the operational state of the container, reducing the need for complex pre-configured sealing structures.

AI summary
A beta container for an alpha-beta port system includes a sheath for receiving transport material and a flange part having a through opening for transferring the transport material from and/or into the sheath, a first interface for a reversible connection to an alpha connection of the port system, and a second interface for releasable attachment of a beta cover for closing the through opening. An edge of the sheath is connected with a first surface of a ring which encompasses a jacket surface of the flange part, the first surface and the jacket surface having different materials. An elastic bellows may be fastened to the flange part such that, in the relaxed state, it engages over the second interface and/or projects out of the through-opening on the side facing away from the sheath, and such that it can be compressed. At least one transponder for transmitting an identification may be arranged on the flange part.
