Single Connecting Rod Pump for High Extraction Capacity

Solution Overview

Problem

Existing pumps require multiple connecting rods, bearings, and membranes for increased extraction capacity, leading to larger sizes, higher costs, and inefficient use of space and resources.

Innovation Solution

A pump design utilizing a single connecting rod with a single bearing for each eccentric, allowing multiple actuators and membranes to be operated efficiently, balancing forces and reducing the need for independent regulation of load points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple connecting rods, bearings, and membranes are used to increase extraction capacity, then the pump can handle higher loads and provide greater extraction capacity, but the pump size increases, weight increases, and manufacturing complexity increases

Engineering Contradiction:

Improveextraction capacityVSAvoidpump size

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The patent combines multiple actuators and membranes onto a single connecting rod, merging functions that traditionally required separate connecting rods. This allows multiple extraction points to be served by one connecting rod, reducing the overall number of connecting rods, bearings, and other components needed in the pump system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single connecting rod is designed to perform multiple functions by supporting several actuators and membranes simultaneously. This multi-functional design allows one connecting rod to replace what would traditionally require multiple separate connecting rods, each serving a single actuator or membrane.

Inventive Principle:

Principle #6Universality (Multi-functionality)
