Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no sensor mechanism is installed in the injection nozzle, then the device complexity is reduced, but the reliability of determining nozzle outlet position is insufficient leading to malfunctions and safety issues
Solution Approach 1:
The patent implements feedback by installing a sensor that detects the position of the valve body outlet (open or closed) and transmits this information to a control system. This feedback mechanism allows the system to monitor the actual state of the nozzle and compare it with the expected state, enabling reliable determination of nozzle outlet position and triggering alerts if malfunctions occur.
Solution Approach 2:
The patent replaces manual inspection or mechanical indication mechanisms with an electronic sensor system. The sensor electronically detects the valve body outlet position and transmits signals to the control system, substituting mechanical or human-based monitoring methods with automated electronic detection, thereby improving reliability while managing complexity through automation.
2Measurement precision
If manual monitoring of nozzle outlet position is performed, then the device complexity is minimized, but the measurement precision of nozzle outlet position is insufficient leading to delayed detection of malfunctions
Solution Approach 1:
The sensor provides real-time feedback on the valve body outlet position, enabling precise measurement and immediate detection of any deviations from the expected state. This continuous monitoring ensures high measurement precision by accurately determining whether the outlet is open or closed at any given moment.
Solution Approach 2:
The patent replaces manual monitoring with automated electronic sensing, achieving precise measurement of the nozzle outlet position through electronic detection rather than human observation. This substitution enables accurate, real-time measurement while managing complexity through automated systems.
3Reliability
If a sensor system is installed to detect nozzle outlet position, then the reliability and measurement precision are improved, but the ease of operation is reduced due to additional monitoring and maintenance requirements
Solution Approach 1:
The sensor system operates autonomously, continuously monitoring the valve body outlet position without requiring manual intervention. The control system automatically receives sensor signals, determines the nozzle state, and triggers alerts or shutdowns if malfunctions are detected, enabling the system to monitor and protect itself without additional operational complexity.
Solution Approach 2:
The feedback mechanism automatically provides information about the nozzle outlet position to the control system, which then autonomously responds to detected malfunctions. This automated feedback loop maintains high reliability while minimizing the need for manual monitoring, as the system self-regulates based on sensor input.
4Productivity
If continuous monitoring of nozzle outlet position is implemented, then the productivity is improved by preventing economic losses, but the use of energy increases due to the sensor and control system operation
Solution Approach 1:
The continuous monitoring through feedback enables early detection of malfunctions, allowing the system to take corrective action (such as shutting down) before significant economic losses occur. This prevents productivity losses from undetected malfunctions, outweighing the energy consumption of the monitoring system itself.
Solution Approach 2:
The automated monitoring and control system operates independently, continuously protecting the system without requiring manual intervention. The energy investment in the sensor and control system is offset by the prevention of much larger economic losses that would result from undetected malfunctions affecting productivity.
