Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of attaching and detaching a pump rod to a reciprocating drive in axial displacement pumps is time-intensive and requires loose parts and multiple tools, complicating the fluid handling components' mounting and removal.
Innovation Solution
A modular pump assembly with a pump module supported by a fluid tank and a removably mountable drive module, utilizing a dynamic and static interface for motive power transfer without breaking electrical or fluid connections, allowing for easy detachment and reattachment of the drive module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump rod is pinned to the reciprocating drive, then the connection is secure and reliable, but the assembly and disassembly process becomes time-intensive and requires multiple tools and loose parts
Solution Approach 1:
The pump system is divided into separate modules: the pump rod assembly and the reciprocating drive assembly. These modules can be independently assembled and disassembled without requiring loose parts or multiple tools, resolving the contradiction by enabling quick module separation while maintaining secure connections within each module during operation.
Solution Approach 2:
The connection between the pump rod and reciprocating drive transitions from a static pinned connection to a dynamic interface that allows for quick assembly and disassembly. The dynamic interface enables the pump rod to be securely connected during operation but easily detached when maintenance is needed, eliminating the time-intensive pinning process while maintaining connection reliability.
2Stability of the object's composition
If the fluid handling components are mounted to the driving portion, then the structure is stable and supported, but the mounting and removal process becomes complex and time-consuming
Solution Approach 1:
The system is segmented into a driving portion and a fluid handling portion that can be independently mounted and dismounted. The fluid handling portion includes the pump rod and cylinder, while the driving portion includes the reciprocating drive mechanism. This segmentation allows the fluid handling components to be securely supported when mounted but easily removed when needed, without requiring complex assembly processes.
Solution Approach 2:
The mounting interface is designed to be universal, allowing the same interface to provide both structural support during operation and facilitate easy mounting and removal. The interface can accommodate different configurations and orientations, enabling the fluid handling components to be securely mounted on the driving portion while allowing for quick detachment for maintenance or reconfiguration.
3Reliability
If multiple tools and loose parts are used for assembly, then the connection can be securely fastened, but the device complexity increases and maintenance becomes more difficult
Solution Approach 1:
The mounting and securing functions are merged into an integrated interface between the pump rod assembly and the reciprocating drive assembly. Instead of using separate loose parts and multiple tools, the interface combines the connection and securing mechanisms into a unified structure that can be assembled and disassembled as a single unit, reducing device complexity while maintaining connection security.
Solution Approach 2:
The modular interface is designed to be self-contained, where the pump rod assembly and reciprocating drive assembly include all necessary mounting features within themselves. This eliminates the need for external loose parts and multiple tools, as each module has its own integrated mounting mechanisms that enable secure connection without adding overall system complexity.
