Solution Overview

Problem

Existing electric pumps require complex and time-consuming assembly and disassembly processes due to the need for individual application and removal of mechanical fixing means, often requiring multiple tools, which complicates maintenance and increases operation time.

Innovation Solution

The electric pump features a detachable association mechanism between the pump body and footing that can be actuated from a single point, utilizing rotatable bars and engagement elements to facilitate easier assembly and disassembly without the need for multiple tools, allowing for quicker association and separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If multiple mechanical fixing means are used to associate the pump body with the footing, then the connection strength and stability are improved, but the assembly and disassembly complexity increases and time consumption increases

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent combines multiple mechanical fixing means into a single integrated fixing means that can simultaneously secure the pump body to the footing. This merging approach maintains the connection strength of multiple fasteners while eliminating the complexity of handling and installing multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single fixing means is designed to perform multiple functions that would traditionally require separate fasteners - it provides both the mechanical connection and the alignment features, and can be operated with a single tool while maintaining the stability of multiple attachment points.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple mechanical fixing means are applied individually, then the secure association between pump body and footing is ensured, but the assembly time and maintenance time increase

Engineering Contradiction:
Improveassociation reliabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing means is pre-configured with alignment features and positioning elements that automatically guide the pump body into the correct position during assembly. This preliminary arrangement eliminates the need for time-consuming alignment operations and ensures reliable association without requiring multiple separate fastening operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fixing means is designed with segmented or modular components that can be independently positioned or adjusted, allowing the assembly to be completed in fewer steps while maintaining the reliability of multiple attachment points through a coordinated single-operating mechanism.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If multiple different tools are required to remove mechanical fixing means, then the complete removal of all fixing means is achieved, but the ease of operation decreases and tool requirements increase

Engineering Contradiction:
Improvemaintenance easeVSAvoidtool requirements
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The single fixing means is designed to be removable with a single tool, eliminating the need for multiple specialized tools that would be required for different fastener types. This universal design maintains ease of repair while reducing tool requirements to just one versatile tool.

Inventive Principle:
Principle #6Universality (Multi-functionality)
