Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-pressure metal hard pipes are used for fracturing fluid transportation, then the pipeline layout is fixed and rigid, but the system becomes complex in layout, difficult to install, and prone to erosion and shaking
Solution Approach 1:
The patent replaces rigid metal hard pipes with flexible pipes that can bend and adapt to different spatial configurations. The flexible pipe system eliminates the need for multiple pipe sections and elbows, reducing layout complexity while maintaining high-pressure transportation capability (≥100 MPa). This directly resolves the contradiction by providing a flexible solution that simplifies installation and reduces shaking.
Solution Approach 2:
The patent changes the physical state parameter of the pipe from rigid (metal hard pipe) to flexible (flexible pipe capable of bending). This parameter change allows the pipe to adapt to spatial requirements without complex joints while maintaining structural integrity under high pressure, thereby reducing both layout complexity and installation difficulty.
2Adaptability or versatility
If multiple sections of pipes and elbows are used to achieve angle and length change, then the pipeline can adapt to different positions, but the installation difficulty and labor intensity increase
Solution Approach 1:
The flexible pipe inherently provides adaptability through its ability to bend and conform to different spatial arrangements. This eliminates the need for multiple rigid pipe sections and elbows, significantly simplifying installation while maintaining the ability to reach different positions and angles.
Solution Approach 2:
The patent merges multiple pipe sections and connection joints into a single flexible pipe unit. This consolidation reduces the number of components that need to be assembled, lowering installation difficulty and labor intensity while preserving the system's adaptability to various configurations.
3Strength
If high-pressure metal hard pipes are used, then the pipeline structure is rigid, but the pipe is prone to shaking during fracturing fluid transportation, reducing service life and increasing safety risks
Solution Approach 1:
The flexible pipe is designed to withstand high pressures (≥100 MPa) while maintaining flexibility. This flexibility allows the pipe to absorb vibrations and shocks during fracturing fluid transportation, reducing shaking and extending service life compared to rigid metal pipes, thereby resolving the contradiction between strength and reliability.
Solution Approach 2:
The patent transitions from a static rigid pipe structure to a dynamic flexible pipe structure that can adapt to vibrations and movements during operation. This dynamic characteristic allows the pipe to dissipate energy from shaking, improving reliability and service life while maintaining the required pressure bearing capacity.
