Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mud pumps are not easily adaptable to changing drilling specifications and require significant space, limiting their ability to increase flow rate or accommodate varying pressure and spacing requirements during drilling operations.
Innovation Solution
A modular pumping system comprising multiple pump assemblies with a power end, fluid end, and transmission, where the power end includes a motor and output shaft, and the fluid end features a piston that reciprocates within a chamber to pressurize the working fluid, allowing for adjustable configuration to meet specific flow rate, pressure, and spacing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mud pumps are used with fixed triplex configuration, then structural stability is maintained, but adaptability to changing drilling specifications deteriorates
Solution Approach 1:
The pump system is divided into modular pump assemblies that can be independently configured and combined. Each pump assembly contains complete functional units (power end, fluid end, transmission) that can be selectively assembled to match specific drilling requirements, enabling adaptability without requiring complete system redesign.
Solution Approach 2:
The system transitions from a fixed static configuration to a dynamic reconfigurable architecture. Pump assemblies can be added, removed, or rearranged based on changing drilling specifications, allowing the system to adapt its capacity and characteristics while maintaining operational simplicity through standardized interfaces.
2Area of stationary object
If conventional mud pumps with large footprint are deployed, then structural stability is ensured, but spatial efficiency deteriorates
Solution Approach 1:
By segmenting the pump system into discrete modular assemblies, the overall footprint is reduced compared to a single large conventional pump. Multiple smaller modular units can be arranged in compact configurations while maintaining the structural stability needed for drilling operations through proper mounting and support structures.
3Productivity
If conventional fixed-capacity pumps are used, then manufacturing simplicity is maintained, but productivity flexibility deteriorates
Solution Approach 1:
The manufacturing process is simplified through modular design where standardized pump assemblies are manufactured independently and then assembled. This segmentation allows for simplified individual component manufacturing while achieving flexible productivity through the ability to combine multiple assemblies in series or parallel configurations to meet varying flow rate requirements.
4Length of stationary object
If conventional pumps requiring significant spacing are installed, then structural stability is maintained, but space utilization deteriorates
Solution Approach 1:
Multiple pump assemblies are merged into a compact integrated system with shared mounting structures and support frameworks. This combining allows the assemblies to be positioned closer together while maintaining the structural stability required for reliable operation, thereby reducing the overall spacing requirements compared to conventional separately-mounted pumps.

AI summary
A pump assembly including a power end including an output shaft having an output shaft axis. In addition, the pump assembly includes a fluid end including a piston configured to reciprocate to pressurize the working fluid. Further, the pump assembly includes a transmission coupled to each of the power end and the fluid end. The transmission includes a carriage coupled to the piston and a pivoting arm pivotably coupled to the carriage at a first connection about a first pivot axis. The first pivot axis extends in a perpendicular direction to a direction of the output shaft axis, and rotation of the output shaft about the output shaft axis is configured to cause the pivoting arm to pivot about the first pivot axis at the first connection and to cause the carriage to reciprocate.
