Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D display is used to show 3D cardiac map, then device complexity is reduced, but spatial accuracy and depth perception deteriorate
Solution Approach 1:
The patent transitions from 2D display to 3D display to represent cardiac anatomy in three dimensions, enabling operators to perceive depth and spatial relationships accurately. This dimensional change resolves the contradiction by providing superior spatial accuracy while the system manages complexity through integrated software and hardware solutions.
2Manufacturing precision
If 2D display is used for catheter manipulation, then ease of operation is maintained, but catheter manipulation precision deteriorates
Solution Approach 1:
The system implements 3D visualization of catheters within the cardiac chambers, allowing operators to precisely track catheter position and manipulate them with improved accuracy. The 3D display provides depth perception that enables precise catheter placement while maintaining operational flow through intuitive interaction.
Solution Approach 2:
The system provides real-time visual feedback showing the exact position of catheters relative to cardiac anatomy in 3D space. This feedback mechanism enables operators to adjust catheter position precisely, improving placement accuracy while the interactive nature maintains ease of operation.
3Measurement precision
If 2D display is used during mapping and ablation, then procedure time is reduced, but spatial resolution and depth perception deteriorate
Solution Approach 1:
The patent employs 3D display technology that renders cardiac anatomy and catheters in three dimensions, providing superior spatial resolution and depth perception. The system achieves this without significantly increasing procedure time by optimizing rendering performance and display technology.
4Ease of operation
If 2D display is used to visualize heart chambers, then device complexity is minimized, but operator fatigue increases
Solution Approach 1:
The system uses 3D visualization that provides more intuitive and easier-to-process information about cardiac anatomy and catheter positions. The enhanced spatial perception reduces the mental load on operators, decreasing fatigue while the system manages the added complexity through integrated software and hardware solutions.

AI summary
A system and method for enhancing visual accuracy comprising a computer processor and memory that executes software to capture the 3D map of the heart images, heart valves, and electro-anatomic data of the heart chambers, and project it into a 3D monitor instead of a 2D monitor, where in the displayed 3D map of the heart images, heart valves, heart chambers anatomy and catheters, is still rendered as a 2D map, which then can be visualized as a real 3D images and map by using/wearing special glasses (3D glasses) designed to view the 3D map of the heart chambers and catheters as 3D in real time.
