Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional robotic catheter control systems are used, then precise catheter control is achieved, but the interface becomes cluttered and requires extensive training
Solution Approach 1:
The patent uses a graphical representation (copy) of the catheter displayed on a touchscreen interface that mirrors the actual catheter's position and orientation in the patient's anatomy. This visual copy allows the operator to intuitively control the physical catheter by interacting with its digital representation, eliminating the need for complex control mappings and extensive training while maintaining precise control.
Solution Approach 2:
The touchscreen display serves as an intermediary between the operator and the robotic catheter system. Instead of directly controlling mechanical components through complex controls, the operator interacts with the visual representation on the touchscreen, which then translates these interactions into precise catheter movements, simplifying the interface while maintaining control precision.
2Adaptability or versatility
If multiple input devices and displays are used for remote catheter navigation, then control functionality is enhanced, but physician fatigue increases and procedural efficiency decreases
Solution Approach 1:
The patent merges multiple control functions and display information into a single touchscreen interface. The touchscreen integrates catheter navigation controls, anatomical mapping visualization, and procedural information display, replacing the traditional multiple keyboards, displays, and mice. This consolidation maintains comprehensive control functionality while eliminating the clutter and fatigue associated with managing multiple separate devices, thereby improving procedural efficiency.
3Ease of operation
If specialized 3D input devices are used for intuitive control, then catheter manipulation is simplified, but physician training requirements increase
Solution Approach 1:
The system creates a visual copy of the catheter on the touchscreen display that accurately represents its position, orientation, and movement in the patient's anatomy. This visual representation allows physicians to control the catheter using familiar touchscreen gestures without requiring training on specialized 3D input devices, maintaining intuitive control while eliminating the training burden.
