Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual filling is used, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to user error and air bubbles
Solution Approach 1:
An automatic transfer station acts as an intermediary device between the supply container and administration container. This mediator performs the fluid transfer operation automatically, eliminating manual handling errors while maintaining system simplicity through a dedicated single-purpose device.
Solution Approach 2:
The transfer station enables self-service fluid transfer by automatically controlling the transfer mechanism based on predetermined parameters. The system performs the filling operation autonomously without requiring user skill or intervention, thereby improving precision while keeping the device relatively simple.
2Device complexity
If manual filling is used, then device complexity is reduced, but loss of time increases due to trial and error operations
Solution Approach 1:
The transfer station is pre-configured with predetermined transfer amounts and parameters before operation. This preliminary setup eliminates the need for trial-and-error adjustments during the actual filling process, significantly reducing filling time while maintaining a simple device structure.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor the fluid transfer process and automatically adjust operations to achieve the predetermined transfer amount. This closed-loop control ensures accurate filling without requiring multiple trial attempts, reducing time loss while keeping the device simple.
3Device complexity
If manual filling is used, then device complexity is reduced, but loss of substance increases due to insulin wastage
Solution Approach 1:
The manual mechanical filling operation is replaced with an automated transfer mechanism controlled by the transfer station. This substitution eliminates imprecise manual measurements and overfilling, reducing insulin wastage while maintaining a relatively simple overall system architecture.
Solution Approach 2:
The transfer station utilizes pneumatic or hydraulic mechanisms to control fluid transfer precisely. This approach enables accurate dosage delivery without manual intervention, minimizing insulin wastage while keeping the device structure simple through the use of standard fluid control components.
4Manufacturing precision
If automatic transfer is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The automatic transfer station is designed as a segmented, modular system with distinct functional components (supply port, exit port, transfer mechanism, control unit). This segmentation allows each component to be optimized independently while maintaining overall system simplicity and ease of manufacturing.
Solution Approach 2:
The transfer station is designed as a universal device that can handle different supply containers and administration containers through standardized interfaces. This multi-functionality reduces the need for multiple specialized devices, thereby improving precision without proportionally increasing overall system complexity.
