Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual embolisation procedure is performed, then the procedure can be performed with simple equipment, but the dose adjustment and catheter withdrawal speed vary between operators leading to uneven agent distribution
Solution Approach 1:
The patent replaces the manual mechanical system with an automated robotic system that uses a motorized drive mechanism to control catheter withdrawal speed and an automated injector to control embolic agent dosage. This substitution eliminates operator variability and ensures precise, uniform distribution of the embolic agent throughout the vessel.
2Manufacturing precision
If automated robotic system is used, then precise dosing and uniform agent distribution are achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into an integrated robotic system where the robotic arm, catheter withdrawal mechanism, embolic agent injector, and polymerization light source are merged into a single coordinated platform. This integration allows precise control of dosing and distribution while managing system complexity through unified design.
Solution Approach 2:
The system dynamically adjusts critical parameters including catheter withdrawal speed, embolic agent dosage volume, and light source intensity based on real-time feedback and pre-programmed protocols. These parameter changes enable precise control over the embolisation process to achieve uniform agent distribution throughout the target vessel.
3Reliability
If dense embolic agent delivery is applied in some areas, then those areas achieve adequate sealing, but thrombophlebitis, induration, and temperature increase occur
Solution Approach 1:
The robotic system incorporates feedback control mechanisms that monitor the distribution and polymerization of the embolic agent in real-time. Based on this feedback, the system automatically adjusts the dosage and withdrawal speed to maintain optimal concentrations, preventing both under-dosing (inadequate sealing) and over-dosing (tissue damage, inflammation, and temperature increase).
