Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double needle is used to establish fluid connection between containers, then sterility is maintained, but flow resistance becomes unreasonably high
Solution Approach 1:
The connection device is divided into separate functional components: a closure element with a thin point for piercing and a ram for applying force. This segmentation allows the piercing function to be separated from the force application, enabling the thin point to create a clean opening while the ram provides controlled force without directly contacting the fluid pathway, thereby reducing flow resistance while maintaining sterility.
Solution Approach 2:
The thin point acts as an intermediary element between the closure element and the fluid connection. It is designed to be pierced by the ram to create an opening, serving as a mediator that enables fluid flow while maintaining the sterile barrier. The thin point's specific geometry (with a tip between two straight legs) allows it to be easily pierced while creating an optimal opening shape for minimal flow resistance.
2Object-generated harmful factors
If a thin point is designed to rupture under ram action, then flow resistance is reduced, but the coupling process becomes more complex
Solution Approach 1:
The coupling process is designed to be self-service through the interaction between the thin point and the ram. When the connection devices are brought together, the ram automatically pierces the thin point of the other device, creating the fluid connection without requiring external intervention or complex mechanisms. The geometry of the thin point (tip between two straight legs) is specifically designed to be easily pierced by the ram, making the coupling process simple and automatic while ensuring low flow resistance.
Solution Approach 2:
The thin point is pre-designed with a specific geometry (tip between two at least substantially straight legs) that anticipates the action of the ram. This preliminary design ensures that when the ram applies force during coupling, the thin point ruptures in a controlled manner to create the optimal opening shape. The preliminary geometric configuration guides the rupture path and ensures minimal flow resistance are achieved automatically during the coupling process.
3Reliability
If containers are sealed separately, then sterility is ensured, but mixing time increases
Solution Approach 1:
The connection devices enable continuous fluid connection between the sealed containers through the thin point rupture mechanism. Once the ram pierces the thin point, the fluid connection is immediately established and maintained continuously, allowing rapid mixing while the containers remain separately sealed until the moment of connection. This continuous action eliminates interruptions and ensures both sterility and speed.
Solution Approach 2:
The system transitions from a static sealed state to a dynamic connected state through the ram's action on the thin point. The thin point's geometry (tip between two straight legs) is designed to rupture dynamically under ram pressure, creating an opening that allows immediate fluid flow. This dynamic transition enables the containers to go from separate and sealed to connected and mixing in a single rapid action, maintaining sterility until the moment of intentional connection.

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 system simplifies and speeds up the mixing process, ensures a specific mixing ratio, and maintains sterility by reducing flow resistance and preventing contamination.
Implementation Method 1
a thin point (5A, 5B) designed to rupture through the application of force by a ram (6B, 6A) of the other or second connection device (4B, 4A), as a result of which the fluid connection can be established
Implementation Method 2
the coupling produces a continuous fluid connection that is closed off from the surroundings, this connection interconnecting the inner chambers (2A, 2B) of the containers (3A, 3B)

AI summary
A container system having connection devices for establishing a fluid connection between the containers. In one aspect, a connection device comprises a thin point that, within its shape, has a tip between two at least substantially straight legs and wherein the other connection device has a ram with a splitting device that is designed and arranged such as to rupture said thin point by acting on the tip when the containers are coupled. In another aspect, the thin point surrounds the ram, and in a third aspect the connection devices have corresponding, similar thin points, closure elements and splitting devices. In further aspects, the connection devices are similar, and the connection devices are linearly guided.
