Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical fluid is transported through pipeline, then production efficiency is improved, but electrostatic charge accumulates in the pipeline
Solution Approach 1:
The system performs preliminary measurement of electrostatic charge before it reaches dangerous levels. The electrostatic measuring device continuously monitors charge accumulation, and the controller activates the solenoid valve to discharge charges when they exceed the predetermined threshold, preventing harmful accumulation before it occurs.
Solution Approach 2:
The system establishes a feedback loop where the electrostatic measuring device continuously monitors charge levels in the pipeline, transmits data to the controller, which then adjusts the solenoid valve state accordingly. This closed-loop control ensures electrostatic charges are actively managed and discharged when necessary, resolving the contradiction between maintaining fluid transport and preventing charge accumulation.
2Reliability
If electrostatic charge is eliminated by discharging, then safety is improved, but fluid flow may be interrupted
Solution Approach 1:
The solenoid valve operates dynamically, switching between open and closed states based on real-time electrostatic charge levels. When charges are low, the valve remains closed to maintain continuous fluid flow. When charges exceed the threshold, the valve opens briefly to discharge charges, then closes again. This dynamic control balances safety requirements with production continuity.
Solution Approach 2:
The system discards (discharges) electrostatic charges only when necessary to maintain safety, using the solenoid valve to release accumulated charges to ground. The fluid flow is recovered and maintained by closing the valve again, allowing normal operation to resume. This selective discarding approach minimizes interruption to fluid flow while ensuring safety.
3Reliability
If deionized water is used to clean the pipeline, then contamination is prevented, but additional equipment and complexity are required
Solution Approach 1:
The solenoid valve serves multiple functions: it controls the discharge of electrostatic charges and also regulates the introduction of deionized water for cleaning the pipeline. This multi-functionality reduces the need for separate cleaning equipment, minimizing additional system complexity while maintaining fluid cleanliness through effective contamination prevention.

AI summary
An active fluid static elimination system installed in a fluid transportation pipeline includes a solenoid valve, an electrostatic measuring device, a fluid destaticizer, and a controller. The solenoid valve is connected to a connecting port of the fluid transportation pipeline, and the electrostatic measuring device is used to measure an electrostatic value of a fluid in the fluid transportation pipeline. The fluid destaticizer is connected to the solenoid valve, and the controller is connected to the electrostatic measuring device and the solenoid valve. The solenoid valve is opened to allow the fluid passing through the fluid destaticizer to eliminate the electrostatic charge of the fluid when the controller determines that the electrostatic value measured by the electrostatic measuring device is greater than a predetermined value.
