Innovation Solution
A field incinerator design featuring a carriage-mounted propane tank with a triple-gauge system and valve configuration, where the first and second gauges control the outlet valve based on pressure thresholds, and the third gauge controls the flame control valve, ensuring precise propane flow and flame management through a main control circuit and flame failure safety circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a simple outlet valve is used without multiple gauges, then the device complexity is reduced, but the pressure control precision and safety cannot be ensured
Solution Approach 1:
The patent divides the pressure control system into multiple independent gauges (first gauge for low pressure threshold, second gauge for high pressure threshold, third gauge for flame control) that each monitor specific pressure conditions. This segmentation allows precise pressure control at different stages while maintaining clear functional separation, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
Each gauge is positioned at a specific location in the propane flow path and monitors local pressure conditions at that point. The first gauge monitors pressure near the tank, the second gauge monitors pressure downstream, and the third gauge monitors pressure at the burner outlet. This local quality approach enables precise control at different locations in the system.
2Reliability
If manual control of propane flow is used, then the ease of operation is improved, but the reliability and safety during operation deteriorates
Solution Approach 1:
The patent implements automatic feedback control where the gauges continuously monitor pressure conditions and automatically adjust the outlet valve and flame control valve accordingly. When the first gauge detects low pressure, it automatically opens the outlet valve; when the second gauge detects high pressure, it automatically closes it. This feedback mechanism ensures reliable operation without requiring constant manual intervention.
Solution Approach 2:
The system performs self-regulation of propane flow and flame control based on pressure conditions detected by the gauges. The automatic valves respond to pressure changes without external control, allowing the system to self-adjust and maintain safe operating conditions autonomously, thereby improving reliability while reducing the operational burden on the user.
3Reliability
If flame control is not automatically managed, then the ease of operation is improved, but the safety and consistent burning conditions deteriorate
Solution Approach 1:
The third gauge provides feedback on pressure conditions at the burner outlet, and the flame control valve automatically adjusts based on this feedback to maintain consistent burning conditions. This automatic feedback control ensures reliable and consistent flame management without requiring complex manual control systems.

Implementation Method 1
The first gauge has a first gauge control parameter. The first gauge control parameter requires less than a first set pressure for activation.
Implementation Method 2
The second gauge is connected to the outlet passage downstream from the first gauge a set distance away from the first gauge. The second gauge has a second gauge control parameter. The second gauge control parameter requires more than a set second pressure for activation.
Implementation Method 3

Implementation Method 4
A burner is connected to the flame control valve. The burner is configured in series with the flame control valve which is in series with the third gauge, outlet valve, second gauge, first gauge, and fuel tank.

AI summary
A field incinerator has a carriage with a frame. A fuel tank such as a propane tank is mounted to the frame. An outlet passage extends from the tank. An outlet valve is mounted to the outlet passage. The outlet valve controls the outlet passage. The first gauge has a first gauge tap. The first gauge tap is connected to the fuel tank or the outlet passage. The first gauge has a first gauge control parameter. The first gauge control parameter requires less than a first set pressure for activation. The second gauge is connected to the outlet passage downstream from the first gauge. The second gauge has a second gauge control parameter. The second gauge control parameter requires more than a set second pressure for activation. The first gauge control parameter and the second gauge control parameter must both be fulfilled for opening the outlet valve.
