Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick thrust needle insertion mechanism is used, then the needle is forced through skin quickly reducing trauma for some patients, but other patients experience increased trauma due to the abrupt motion
Solution Approach 1:
The needle insertion mechanism transitions from a static quick-thrust design to a dynamic controlled-rate system. The drive mechanism adjusts the insertion speed based on real-time feedback from force sensors, allowing the system to optimize between quick insertion (for patients tolerating faster rates) and slower insertion (for patients requiring gentler insertion), thereby resolving the contradiction between insertion efficiency and patient comfort.
Solution Approach 2:
Force sensors mounted on the needle assembly provide real-time feedback during insertion. This feedback loop allows the control system to monitor resistance forces and adjust the drive mechanism accordingly, enabling adaptive insertion rates that reduce trauma for different patients while maintaining overall insertion efficiency.
2Device complexity
If manual needle insertion is used, then the insertion process is simple and controllable, but it is traumatic and time-consuming for the user
Solution Approach 1:
The system employs self-service principles where the needle insertion mechanism automatically performs the insertion without requiring manual manipulation by the user. The automated drive mechanism, guided by force feedback sensors, handles the insertion process independently, eliminating the need for users to manually control a traumatic process while maintaining simplicity in the overall device architecture.
Solution Approach 2:
The manual mechanical insertion process is replaced with an automated electromechanical system. The drive mechanism uses controlled motor actuation instead of manual pushing, and force sensors replace human tactile feedback, substituting mechanical human operation with an automated sensing and actuation system that reduces trauma.
3Device complexity
If traditional fluid delivery systems are used, then the system structure is simple, but there is no effective detection method for fluid presence in the conduit
Solution Approach 1:
Traditional mechanical fluid presence detection methods are replaced with optical detection systems. Optical sensors detect the presence and characteristics of fluid in the conduit through non-contact means, eliminating the need for complex mechanical sensors or sampling mechanisms while providing accurate real-time fluid monitoring.
Solution Approach 2:
The system utilizes optical properties including color changes or light absorption characteristics of the fluid to detect its presence in the conduit. Optical sensors measure these properties to determine fluid presence and characteristics, providing effective detection without adding mechanical complexity to the system structure.
