Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional infusion devices are used for hazardous drug administration, then ease of operation is maintained, but reliability deteriorates due to insecure connections and inadvertent disconnections
Solution Approach 1:
The infusion system is divided into separate functional components: an infusion adapter with spike and grip portion for container attachment, a connection adapter with spike port and Luer connector for fluid pathway connection, and a syringe adapter. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability through modular assembly.
Solution Approach 2:
The infusion adapter acts as an intermediary component between the infusion container and the connection adapter. It provides a sealed interface with a membrane that prevents direct contact between the hazardous drug and the operator while maintaining fluid pathway integrity, thus mediating the hazardous interaction.
2Adaptability or versatility
If multiple IV lines are used for drug administration, then adaptability is improved, but the risk of exposure increases due to more connection points
Solution Approach 1:
The connection adapter combines multiple functions into a single integrated component: it receives the infusion adapter, provides a spike port for patient line connection, and includes a Luer connector for syringe attachment. This merging reduces the number of separate connection points and minimizes exposure risks while maintaining fluid transfer versatility.
3Ease of operation
If open transfer of hazardous drugs is performed, then ease of operation is maintained, but harmful factors increase due to potential leakage and uncontrolled spiking
Solution Approach 1:
The infusion adapter incorporates a flexible membrane that seals the passageway at the second end while allowing controlled fluid transfer. This thin film creates a closed system that prevents drug leakage and uncontrolled spiking while maintaining operational simplicity through its flexible, easy-to-attach design.
