Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional flow ports are used in medical devices, then manufacturing process is simpler, but contamination risk increases and cleanliness of biopharmaceutical fluids deteriorates
Solution Approach 1:
The flow port is divided into distinct functional segments: an elliptic body portion that interfaces with the container and a hose barb portion that connects to fluid transport lines. This segmentation allows each portion to be optimized for its specific function while maintaining overall cleanliness and preventing contamination pathways.
Solution Approach 2:
The flow port incorporates a three-dimensional elliptic body shape with edges extending in multiple directions, creating a multi-dimensional sealing interface. This geometric complexity in multiple dimensions enhances seal quality and prevents contamination without requiring additional separate components.
2Manufacturing precision
If conventional flow ports are used, then device structure is simpler, but seal quality deteriorates and manufacturing scrap rates increase
Solution Approach 1:
The flow port employs an asymmetric elliptic body shape with non-uniform curvature and edges of different lengths extending from the body. This asymmetric geometry creates optimal sealing contact surfaces that improve seal quality and reduce manufacturing defects while maintaining structural integrity.
Solution Approach 2:
The elliptic body portion features curved surfaces and rounded edges that provide smooth transitions and optimal contact surfaces for sealing. The curved geometry eliminates sharp corners that could create stress concentrations or sealing defects, thereby improving seal quality and reducing scrap rates.
3Reliability
If flow ports without edges are used, then manufacturing is easier, but seal quality deteriorates and container failure instances increase
Solution Approach 1:
The flow port is designed with pre-formed edges and geometric features that are integrated into the single-piece molded structure. These sealing edges are created during the initial manufacturing process rather than requiring subsequent assembly steps, thereby improving reliability while maintaining ease of manufacture through single-step production.
Solution Approach 2:
The flow port combines multiple functions into a single integrated component: the elliptic body provides sealing surfaces, the edges create sealing contact points, and the hose barb portion enables fluid connection. This merging of functions into one piece eliminates assembly errors and improves reliability without complicating the manufacturing process.

AI summary
A biopharmaceutical flow port, a biopharmaceutical liquid container assembly, and a method for manufacturing the biopharmaceutical flow port and the biopharmaceutical liquid container assembly are described. The biopharmaceutical flow port includes a hose barb coupled to an elliptic body. The hose barb includes a bore. The elliptic body includes a flow passage, a first edge, and a second edge. The flow passage is fluidly coupled to the bore. The first edge extends from the elliptic body away from the flow passage in a first direction and the second edge extends from the elliptic body away from the flow passage in a second direction opposite the first direction. The biopharmaceutical liquid container assembly includes a biopharmaceutical liquid container with an opening and the biopharmaceutical flow port coupled to the biopharmaceutical liquid container within the opening and in fluid communication with a volume of the biopharmaceutical liquid container.
