Solution Overview

Problem

Powdered materials tend to settle within pump cylinders, leading to reduced efficiency and structural integrity issues due to adherence to cylinder walls and compacting, which impedes effective movement and can damage the pump.

Innovation Solution

A conduit system is integrated into the pump to direct fluid between cylinders, aerating and agitating the powdered material to prevent settling and enhance movability, thereby improving operational efficiency and maintaining structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If powdered material is moved through cylinders without fluid aeration, then the pump structure remains simple, but the powdered material settles and compacts, reducing pump efficiency and potentially damaging the pump

Engineering Contradiction:
Improvepump efficiencyVSAvoidpump structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a conduit system that directs fluid (gas or liquid) into the cylinder to aerate the powdered material. This pneumatic/hydraulic approach suspends the powder particles in the fluid stream, preventing settling and compaction, thereby maintaining pump efficiency without requiring complex mechanical modifications to the pumping mechanism itself

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The fluid acts as an intermediary medium between the powdered material and the cylinder walls. By introducing this intermediate fluid phase, the powder particles remain suspended and entrained in the fluid flow, preventing direct contact and adhesion to cylinder walls that would otherwise occur, thus maintaining flowability and reducing wear

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If fluid is directed into the cylinder to aerate powdered material, then powdered material settling is prevented and movability is enhanced, but the pump structure becomes more complex with added conduit system

Engineering Contradiction:
Improvestructural integrityVSAvoidconduit system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The conduit system utilizes pneumatic or hydraulic principles to direct fluid into the cylinder. This approach maintains structural integrity by preventing powder compaction and adhesion to cylinder walls, while the conduit design integrates efficiently into the existing pump architecture, minimizing the complexity increase

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The fluid system serves multiple functions simultaneously: it aerates the powder to prevent settling, maintains structural integrity by preventing wall adhesion, and can be integrated with the pump's existing drive mechanism. The piston's reciprocating motion that drives powder discharge also creates pressure differentials that facilitate fluid flow through the conduit system

Inventive Principle:
Principle #25Self-service

AI summary

A pump includes a cylinder and a piston disposed within the cylinder to define a first chamber and a second chamber within the cylinder. The piston is configured to move within the cylinder to reduce a size of the first chamber to discharge material from the first chamber. The pump also includes a conduit system configured to direct fluid into the first chamber to aerate material in the first chamber.
