Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gas filters are disposed at the rear of turbine fracturing trucks in high-pressure regions, then gas supply is achieved, but the risk of filter damage and safety hazards increases
Solution Approach 1:
The gas filter is extracted from the high-pressure region (rear of truck) and relocated to a safe position (front of truck or separate location). The patent provides separate gas supply paths: one for the high-pressure fracturing system and another for the turbine engine, allowing the filter to be positioned away from the hazardous high-pressure zone while maintaining gas supply functionality.
Solution Approach 2:
The gas supply system is segmented into distinct functional zones: a high-pressure fracturing gas supply path and a separate turbine engine gas supply path. This segmentation allows the filter to be positioned in the turbine supply path away from high-pressure regions, reducing damage risk while maintaining operational effectiveness.
2Adaptability or versatility
If gas pipelines are arranged in annular form connecting all turbine fracturing trucks, then gas distribution is achieved, but system complexity and inter-vehicle dependency increase
Solution Approach 1:
The annular piping system is divided into independent radial supply lines, each connecting the central gas source to individual turbine fracturing trucks. This segmentation allows each truck to be supplied independently, reducing system complexity and eliminating the need for a complex inter-connected annular network while maintaining gas distribution capability.
3Reliability
If temporary installation of gas filters and pipelines is required after wellsite arrangement, then gas supply system is established, but installation time and labor consumption increase
Solution Approach 1:
Gas filters and piping components are pre-assembled into integrated units or pre-positioned at the wellsite before the fracturing operation begins. The patent describes arrangements where filters are pre-installed at designated locations and pipelines are pre-laid, eliminating the need for temporary installation after equipment arrival and reducing overall installation time.
4Reliability
If the entire pipeline must be shutdown to add fuel line, then system integrity is maintained, but operational efficiency decreases
Solution Approach 1:
The fuel line addition operation is extracted from the main gas supply system, allowing it to be performed independently on a separate branch or through a dedicated access point. The patent enables adding fuel lines to the turbine supply system without shutting down the main high-pressure gas pipeline, maintaining system integrity while improving operational efficiency.
