Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a catheter is used for vascular therapy, then the procedure can be performed, but it is difficult to apply to complex blood vessels and success depends on doctor proficiency
Solution Approach 1:
The patent replaces manual mechanical catheter manipulation with a magnetic robot system that can be wirelessly controlled. The mobile robot with magnetic coupling parts allows for automated navigation through complex blood vessels, reducing dependence on doctor proficiency while improving adaptability to various vascular geometries.
2Extent of automation
If magnetic robots move by floating or frictional contact in vessels, then wireless driving is achieved, but maintaining position and posture becomes difficult in dynamic vessel environments
Solution Approach 1:
The patent applies preliminary action by pre-coupling the mobile robot to the catheter using magnetic coupling parts before entering the vessel. This initial secure attachment ensures stable position and posture maintenance during navigation, while still allowing wireless driving through the catheter system.
Solution Approach 2:
The mobile robot is nested within the catheter structure, with the catheter providing a guiding framework and the robot providing wireless autonomous capability. This nested configuration allows the robot to maintain stable position while benefiting from the catheter's structural support.
3Productivity
If magnetic coupling is used to transport the mobile robot, then transportation to lesion sites is achieved, but the robot cannot be easily recovered after treatment
Solution Approach 1:
The patent applies dynamics by making the magnetic coupling reversible. The mobile robot can be dynamically coupled to the catheter for transportation to the lesion site, then dynamically decoupled after treatment using an external magnetic field to rotate the driving magnet and release the magnetic attraction. This enables easy recovery and reuse of the robot.
