Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional catheter-based delivery methods are used, then the procedure can be performed with simpler equipment, but the precision and control of implant deployment are insufficient
Solution Approach 1:
The patent replaces traditional mechanical catheter-based delivery systems with a motorized delivery system that uses electromagnets and motors to actuate the implant deployment mechanism, enabling precise control through electrical signals rather than manual mechanical manipulation
Solution Approach 2:
The patent incorporates sensors that detect the position and status of the implant during delivery, providing feedback signals to a controller that adjusts motor actuation in real-time to achieve precise deployment at the target location
2Reliability
If open heart surgery is used for valve replacement, then secure attachment to intralumenal tissue can be achieved, but patient trauma is significant
Solution Approach 1:
The patent replaces traumatic mechanical open-heart surgical procedures with a motorized percutaneous delivery system that uses electromagnets to securely attach the implant to intralumenal tissue through the vessel wall, achieving reliable attachment without large incisions or heart stopping
Solution Approach 2:
The patent uses the delivery catheter and motorized actuation mechanism as an intermediary to transfer the implant from the external delivery system to the target location within the body, enabling secure attachment without direct surgical access to the heart or valve
3Object-affected harmful factors
If percutaneous delivery through tortuous vasculature is attempted, then patient trauma is reduced, but navigation and positioning control become difficult
Solution Approach 1:
The patent replaces manual mechanical navigation of catheters through tortuous vasculature with a motorized delivery system that uses sensors and controlled motor actuation to navigate and position the implant with precision, converting difficult manual manipulation into automated controlled movement
Solution Approach 2:
The patent uses sensors to detect the position and orientation of the delivery system as it navigates through the vasculature, providing real-time feedback that enables the operator to adjust the course and achieve accurate positioning at the target location
4Manufacturing precision
If manual deployment methods are used, then the delivery system can be simpler, but deployment accuracy and consistency are poor
Solution Approach 1:
The patent replaces manual mechanical deployment with a motorized deployment system that uses electromagnets and controlled motor actuation to deploy the implant with high precision and consistency, eliminating variability associated with manual operation
Solution Approach 2:
The patent incorporates sensors that monitor the deployment process in real-time, providing feedback to the control system that adjusts motor actuation to achieve consistent and accurate deployment outcomes across different procedures and operators
