Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional energy delivery methods are used to treat hypertension and CHF, then energy can be delivered to target tissues, but electrical leakage causes damage to neighboring nerves and organs
Solution Approach 1:
The system performs preliminary impedance measurements between electrode pads before delivering therapeutic energy. By measuring impedance values and calculating electrical leakage estimates in advance, the system identifies potential leakage paths and adjusts energy delivery parameters to prevent damage to neighboring tissues and organs.
Solution Approach 2:
The system continuously monitors impedance between electrode pads and uses this feedback to calculate electrical leakage estimates. Based on these real-time measurements, the control unit adjusts energy delivery parameters dynamically to maintain safe operating conditions and prevent harmful electrical leakage to surrounding tissues.
2Reliability
If traditional denervation procedures are performed, then nerve activity can be targeted, but the procedures are time-consuming and difficult to perform
Solution Approach 1:
The system automatically performs impedance measurements, calculates electrical leakage estimates, and adjusts energy delivery parameters without requiring manual intervention. The control unit autonomously optimizes treatment parameters based on real-time impedance data, eliminating time-consuming manual adjustments and simplifying the procedural workflow.
Solution Approach 2:
The system dynamically changes energy delivery parameters based on measured impedance values and calculated leakage estimates. By automatically adjusting voltage, current, or pulse duration parameters in response to real-time measurements, the system achieves effective denervation while reducing procedural time and complexity.
3Measurement precision
If impedance measurements are taken between electrode pads, then electrical leakage can be detected, but the measurement process becomes complex
Solution Approach 1:
The control unit performs multiple functions using the same impedance measurement infrastructure: it measures impedance between electrode pads, calculates electrical leakage estimates, and uses these data to guide energy delivery. This multi-functional approach achieves precise leakage detection without requiring separate dedicated measurement systems for each function.
Solution Approach 2:
The system uses impedance measurements as an intermediary parameter to infer electrical leakage characteristics. Rather than directly measuring leakage current, the system measures impedance between electrode pads and uses this intermediate measurement to calculate leakage estimates, simplifying the measurement process while maintaining detection precision.
