Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of diesel-driven apparatuses in fracturing well sites poses challenges due to low power density, high noise, and environmental pollution, while electric-driven systems risk accidents like fire and explosion from electric shock.
Innovation Solution
A fracturing well site system that incorporates an electric-driven apparatus, a fuel-driven apparatus, an electric-power supply apparatus, and a grounding system with a first grounding terminal spaced from each apparatus, connecting the fuel-driven and at least one electric-driven or electric-power supply apparatus to the terminal for grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a diesel-driven apparatus is used for fracturing operations, then the system can operate without external power supply, but the power density is low, noise is high, and environmental pollution increases
Solution Approach 1:
The patent combines both diesel-driven apparatus and electric-driven apparatus in a single fracturing system. The diesel engine serves as the primary power source while electric motors assist in specific operations, merging the advantages of both power sources to reduce noise and pollution while maintaining operational independence
Solution Approach 2:
The system is designed with multi-functional capability where the diesel-driven apparatus can operate independently without external power supply, while also being capable of integrating with electric-driven components when power is available, making the system adaptable to different operational conditions
2Power
If an electric-driven apparatus is used for fracturing operations, then power density is high and noise is low, but the risk of fire and explosion from electric shock increases
Solution Approach 1:
The patent introduces a grounding system as an intermediary safety mechanism between the electric-driven apparatus and the environment. This grounding system provides a safe path for electrical currents, reducing the risk of electric shock, fire, and explosion while allowing the high-power electric motors to operate
Solution Approach 2:
The patent extracts the safety function from the main power transmission system by implementing a separate grounding system. This dedicated safety infrastructure handles electrical hazards independently, allowing the electric-driven apparatus to operate at high power density with reduced risk
3Reliability
If multiple grounding terminals are installed for each apparatus, then safety is improved, but the number of grounding terminals and operational workload increases
Solution Approach 1:
The patent merges multiple grounding requirements into a single integrated grounding system. Instead of installing separate grounding terminals for each apparatus, the system uses one centralized grounding terminal that serves all equipment, reducing complexity while maintaining safety through proper electrical connection and potential equalization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces the number of grounding terminals and operational workload, while ensuring safety by directing leakage current and static charge away from the apparatuses, thereby preventing accidents and ensuring normal operation.
Implementation Method 1
the first grounding terminal is configured to ground the fuel-driven apparatus and the at least one of the electric-driven apparatus and the electric-power supply apparatus
