Solution Overview
Problem
Existing pipeline cleaning and inspection methods lack an efficient and accurate way to control the speed of inline tools, such as pigs, which require specific velocity ranges for effective operation.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If pressurized gas is introduced to move the pipeline pig, then the pig can travel through the pipeline, but the velocity cannot be accurately controlled
Solution Approach 1:
The system controls pig velocity by regulating gas flow rate and pressure parameters. The flow control valve adjusts the volumetric flow rate of pressurized gas, while the pressure regulator maintains consistent gas pressure, thereby controlling the pig's velocity through parameter adjustment rather than direct mechanical control
Solution Approach 2:
The system employs feedback control where velocity sensors monitor the pig's actual velocity and transmit this data to the control system. The control system then adjusts the flow control valve to maintain the desired velocity, creating a closed-loop control system that ensures accurate velocity control
2Productivity
If high pressure gas is used to move the pig quickly, then productivity increases, but the pig may overspeed and cause safety issues
Solution Approach 1:
The system transitions from static pressure application to dynamic control where the gas flow rate and pressure are continuously adjusted based on real-time velocity feedback. This allows the system to optimize productivity by using higher pressures when needed while automatically reducing pressure to prevent overspeeding, thereby maintaining safety
Solution Approach 2:
The control system is configured with predetermined velocity limits and safety thresholds. Before overspeeding can occur, the system preemptively adjusts the gas flow to prevent exceeding safe velocity parameters, thus preventing safety issues before they arise rather than reacting after overspeed occurs
