Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump systems with multiple modules are cumbersome to install and replace, especially for inexperienced personnel, due to complex mechanical and fluid connections, which can lead to errors and reduced operational readiness.
Innovation Solution
The pump system features detachable mechanical and fluid interfaces that allow for tool-free connections and easy module replacement, with a plug/swivel connection design and locking elements for secure assembly, enabling reliable and user-friendly installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pump modules are connected in series or parallel to increase pump pressure or volume flow, then the pump system functionality is improved, but the complexity of mechanical and fluid connections increases, making installation and replacement time-consuming and error-prone
Solution Approach 1:
The patent applies universality by designing a standardized interface that serves multiple functions: mechanical connection, fluid connection, and electrical connection. This single integrated interface can be used for all pump modules regardless of their specific function (series or parallel configuration), allowing the same interface design to support diverse pump system functionalities while simplifying installation and replacement procedures.
2Reliability
If traditional mechanical and fluid connections are used for pump modules, then reliable connection is achieved, but installation and replacement require tools and are time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the connection system into separable interface components that can be quickly assembled and disassembled. The interface is segmented into male and female parts with complementary features (locking projections and recesses) that enable tool-free connection while maintaining reliable mechanical and fluid seals. This segmentation allows rapid module replacement without requiring tools or complex assembly procedures.
3Ease of operation
If pump modules are designed with detachable interfaces for easy replacement, then ease of operation is improved, but the risk of assembly errors may increase
Solution Approach 1:
The patent applies asymmetry by designing non-symmetric interface features including specifically positioned locking projections and recesses, asymmetric sealing surfaces, and keyed electrical contacts. These asymmetric features ensure that pump modules can only be connected in the correct orientation, preventing assembly errors while maintaining ease of operation. The asymmetric design provides built-in guidance and verification that the module is properly installed.
