Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fracturing fluid delivery systems face challenges in efficiently and reliably connecting flexible fracturing fluid conduits to wellhead assemblies, particularly due to erosion from abrasive particulates and the need for secure, easy installation and disconnection of these conduits during fracturing operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rigid piping systems are used for fracturing fluid delivery, then structural strength and pressure resistance are maintained, but flexibility and ease of installation are reduced
Solution Approach 1:
The system divides the fluid delivery pathway into rigid pipe sections and flexible conduit sections that can be independently connected and disconnected. The flexible conduits are segmented into manageable lengths that can be easily installed and removed, resolving the contradiction between maintaining structural integrity and enabling ease of installation.
Solution Approach 2:
The system transitions from entirely rigid piping to a hybrid system incorporating flexible conduits that can dynamically adapt to different installation configurations. The flexible portions allow for movement and positioning adjustments during installation while maintaining secure connections at the wellhead assembly, thereby improving ease of operation without sacrificing adaptability.
2Productivity
If quick connectors are used to facilitate easy connection and disconnection, then installation efficiency is improved, but connection reliability and security may be compromised
Solution Approach 1:
The quick connectors are pre-configured with alignment features and engagement mechanisms that guide proper connection before final locking occurs. The system performs preliminary alignment and seating actions automatically during the connection process, ensuring reliable engagement before the quick release mechanism is fully activated, thus maintaining both installation efficiency and connection reliability.
Solution Approach 2:
The quick connector system incorporates feedback mechanisms such as visual indicators, mechanical interlocks, and sensing elements that confirm proper connection status. This feedback ensures that the connector is reliably engaged before allowing operation to proceed, preventing premature disconnection while maintaining quick connection capabilities, thereby resolving the contradiction between installation efficiency and connection reliability.
3Adaptability or versatility
If flexible conduits are used to improve routing flexibility, then adaptability is enhanced, but susceptibility to erosion from abrasive particulates increases
Solution Approach 1:
The flexible conduits are constructed using composite materials that combine the flexibility needed for routing adaptability with erosion-resistant properties. The composite structure may include abrasive-resistant liners, reinforced walls, or specialized coatings that protect against particulate erosion while maintaining the conduit's flexible characteristics, thus resolving the contradiction between routing flexibility and erosion susceptibility.
Solution Approach 2:
The system applies different material qualities to different sections of the flexible conduit. High-wear areas near the wellhead assembly and connection points are reinforced with erosion-resistant materials, while other sections maintain maximum flexibility. This localized differentiation allows the conduit to achieve both routing adaptability and resistance to abrasive particulates in critical areas.
4Reliability
If secure locking mechanisms are implemented to ensure connection security, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the natural forces present during connection. As the flexible conduit is inserted into the quick connector, the engagement of internal features automatically triggers the locking action without requiring external actuators or complex control systems. This self-service approach ensures reliable locking while minimizing added complexity, resolving the contradiction between connection security and device complexity.
