Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to regulate liquid pressure, then flexibility and adaptability are maintained, but the process is time-consuming and prone to errors due to healthcare provider workload
Solution Approach 1:
The system enables self-regulation through automatic control. The liquid pressure sensor continuously monitors pressure, the level sensor monitors liquid level, and the control module automatically activates the pump or valve to maintain target pressure without requiring continuous manual intervention, thereby resolving the contradiction between regulation speed and system complexity
Solution Approach 2:
The system implements closed-loop feedback control where sensor readings are continuously fed back to the control module, which adjusts the pump or valve operation in real-time based on deviations from target pressure, enabling automatic regulation while maintaining safety
2Reliability
If manual monitoring and adjustment is performed, then healthcare providers can adapt to patient conditions, but the risk of oversupply increases due to provider workload and distraction
Solution Approach 1:
The system provides continuous automatic monitoring and adjustment without interruption. The sensors continuously measure pressure and liquid level, and the control module continuously adjusts the pump or valve operation, eliminating the discontinuous manual monitoring process that leaves patients at risk during transitions between measurements
Solution Approach 2:
The patent replaces the mechanical manual operation system with an automated control system using sensors, control modules, and electronic actuators, eliminating human error and distraction while maintaining precise regulation through electronic control
3Manufacturing precision
If frequent manual measurement and adjustment is performed, then pressure control precision is maintained, but the treatment becomes time-consuming and resource-intensive
Solution Approach 1:
The patent introduces sensor systems and control modules as intermediaries between the liquid pressure and the adjustment mechanism. These intermediaries continuously monitor pressure and automatically trigger adjustments, maintaining precision without requiring frequent manual intervention and thereby improving treatment efficiency
