Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional interventional procedures are used for cardiac ablation, then the procedure can be performed, but it is difficult to precisely direct treatment to targeted anatomic regions without damaging surrounding tissue
Solution Approach 1:
The patent transitions from two-dimensional imaging to three-dimensional visualization of cardiac anatomy. The 3D imaging system creates a volumetric representation of the heart chambers and vasculature, allowing operators to navigate and target ablation sites with spatial precision in all three dimensions, thereby improving targeting accuracy and avoiding damage to surrounding tissue.
Solution Approach 2:
The patent introduces an imaging and navigation system as an intermediary between the operator and the ablation procedure. This system includes 3D imaging devices, tracking systems, and visualization software that mediate the targeting process by providing real-time anatomical information and guidance, enabling precise direction of treatment to targeted anatomic regions.
2Ease of operation
If traditional interventional procedures are used for cardiac ablation, then the procedure can be performed, but it is difficult to visualize and access appropriate anatomic regions in a minimally invasive manner
Solution Approach 1:
The imaging and navigation system serves as an intermediary that enhances the operator's ability to visualize and access anatomic regions during minimally invasive procedures. The system integrates 3D imaging, catheter tracking, and real-time visualization to provide comprehensive anatomical information without requiring open surgical access, thereby maintaining minimally invasive benefits while improving visualization and reducing complications.
Solution Approach 2:
The patent replaces mechanical exploration and visualization methods with advanced imaging technologies. Instead of relying on tactile feedback and limited 2D imaging, the system uses 3D imaging devices, electromagnetic tracking, and computer-generated visualizations to provide comprehensive anatomical information, making minimally invasive procedures safer and more effective.
3Measurement precision
If real-time 3D imaging and navigation systems are implemented, then precision and safety of cardiac ablation procedures are enhanced, but the device complexity increases
Solution Approach 1:
The imaging and navigation system is designed to perform multiple functions within a single integrated platform. The system combines 3D imaging, catheter tracking, anatomical visualization, navigation guidance, and procedural monitoring capabilities, allowing a single system to address multiple procedural needs and reducing the overall complexity that would result from using separate independent systems.
Solution Approach 2:
The patent merges previously separate systems into an integrated imaging and navigation platform. The system combines 3D imaging devices, electromagnetic tracking systems, visualization software, and navigation algorithms into a unified system that operates seamlessly together, thereby managing complexity through integration rather than through multiple independent components.
