Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If diesel engine is used to drive fracturing plunger pump through transmission shaft, then power transmission is achieved, but volume and weight increase significantly
Solution Approach 1:
The patent removes the transmission shaft from the system by directly coupling the diesel engine's output end to the fracturing plunger pump's input end. This extraction of the intermediate transmission component reduces both weight and volume while maintaining power transmission capability.
Solution Approach 2:
The patent merges the diesel engine and fracturing plunger pump into a directly connected integrated unit, eliminating the transmission shaft. This merging reduces the number of components, decreases overall weight, and simplifies the structural configuration while preserving the power transmission function.
2Power
If diesel engine is used to drive fracturing plunger pump, then power transmission is achieved, but environmental pollution and noise increase
Solution Approach 1:
The patent converts the harmful exhaust from the diesel engine by integrating an exhaust purification device that treats the waste gas before discharge. This transforms the harmful factor into a beneficial outcome by reducing environmental pollution while maintaining the diesel engine's power transmission advantages.
3Power
If diesel engine and transmission are used to drive fracturing plunger pump, then power transmission is achieved, but initial purchase cost and maintenance cost increase
Solution Approach 1:
The patent extracts the transmission shaft and related transmission components from the system, directly coupling the diesel engine to the fracturing plunger pump. This reduction in component count lowers initial purchase costs and decreases routine maintenance requirements while maintaining adequate power transmission.
4Object-generated harmful factors
If electric motor is used to drive fracturing plunger pump, then environmental pollution is reduced, but power supply reliability decreases due to generator shutdown risks
Solution Approach 1:
The patent accepts the environmental drawback of diesel engine operation but converts this apparent harm into a benefit by achieving superior reliability. The direct-coupling design eliminates transmission failures, and the robust mechanical power transmission provides more reliable operation compared to electric drive systems dependent on generator stability.
5Power
If transmission shaft is used to connect diesel engine and fracturing plunger pump, then power transmission is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the transmission shaft from the system, creating a direct coupling between the diesel engine and fracturing plunger pump. This simplification reduces device complexity by eliminating intermediate components and their associated mounting, alignment, and maintenance requirements.
Solution Approach 2:
The patent merges the diesel engine and fracturing plunger pump into a directly connected integrated unit, eliminating the transmission shaft and reducing structural complexity. This merging simplifies the overall device configuration while maintaining power transmission functionality.
