Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple pressure sensors are arranged inside the perfusion object to ensure measurement accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a fluid column as an intermediary medium to transmit pressure from the perfusion object to a single pressure sensor located in the fluid supply line. This allows accurate pressure measurement without placing multiple sensors inside the perfusion object, thus maintaining measurement precision while reducing device complexity
Solution Approach 2:
The patent replaces the mechanical approach of using multiple physical pressure sensors inside the perfusion object with a fluid-based pressure transmission system. The fluid column acts as a pressure transmission medium, substituting the need for multiple mechanical sensors with a single sensor connected through the fluid line
2Reliability
If internal pressure is adequately maintained through water feeding and suction, then reliability of stone collection is improved, but device complexity increases due to need for pressure monitoring systems
Solution Approach 1:
The patent implements a feedback control system where the pressure sensor continuously monitors pressure in the fluid supply line, and the controller adjusts water feeding and suction operations based on the measured pressure values. This ensures reliable stone collection by maintaining optimal pressure conditions while using a simple single-sensor monitoring system
Solution Approach 2:
The system uses the existing fluid supply line and pressure sensor to automatically monitor and regulate pressure conditions for stone collection. The controller autonomously adjusts water feeding and suction based on pressure feedback, making the system self-regulating without requiring complex external monitoring equipment
