Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated systems are introduced for blood component processing, then productivity and accuracy improve, but device complexity increases
Solution Approach 1:
The automated blood processing system is divided into distinct functional modules: a durable processing device containing motors, controllers, and separation mechanisms, and a disposable fluid flow circuit containing tubing, containers, and filters. This segmentation allows the complex automated functions to be distributed across separate components that can be independently manufactured, validated, and replaced, resolving the contradiction between automation capability and system complexity.
Solution Approach 2:
The disposable fluid flow circuit acts as an intermediary between the donor's blood and the durable processing device. It pre-assembles the fluid pathway with integrated containers and filters, eliminating the need for complex manual connections during blood collection and processing. This intermediary component simplifies the overall system operation while maintaining high automation capability in the durable device.
2Device complexity
If manual collection procedures are used, then device complexity remains low, but loss of time and productivity decrease
Solution Approach 1:
The disposable fluid flow circuit is pre-assembled with all necessary tubing, containers, and filters before use. The blood collection bag is pre-filled with anticoagulant, and the entire fluid pathway is prepared in advance. This preliminary preparation eliminates time-consuming manual assembly and setup during the actual blood collection and processing operation, significantly reducing loss of time while keeping the collection device itself simple.
3Reliability
If automated authentication systems are implemented, then reliability of blood component verification improves, but device complexity increases
Solution Approach 1:
The authentication system replaces manual visual inspection of container labels and barcodes with an automated optical scanning system. The durable processing device includes a scanner that automatically reads identification markers on containers, and a controller that verifies container authenticity and tracks blood components. This substitution of mechanical/manual verification with automated optical and electronic systems significantly improves reliability while the modular design keeps the added complexity manageable.

Function Achieved in This Case
The proposed solutions automate the blood processing workflow, reducing human error and increasing efficiency in the separation and processing of blood components, while ensuring the authenticity and tracking of blood containers.
Implementation Method 1
scanning a barcode on a surface of the container with a barcode scanner
Implementation Method 2
membrane separators, having an interior collection system, disposed within a stationary shell or housing... Plasma passes through the membrane
Implementation Method 3
employ an automated blood component separator for such post-collection processing... have been found to provide excellent plasma filtration rates, due primarily to the unique flow patterns induced in the gap between the spinning membrane and the shell

AI summary
A blood processing device includes a controller and a scanner coupled to the controller. The scanner is configured to scan a two-dimensional barcode associated with a component of a disposable processing circuit that is configured to be used in combination with the blood processing device. The scanner transmits a signal to the controller based on information derived from the two-dimensional barcode, with the controller determining information encoded into the two-dimensional barcode based on the signal received from the scanner.
