Submersible Pump Segmentation for Height-Volume Trade-off

Solution Overview

Problem

Conventional submersible pumps struggle to create both high-height and high-volume water displays simultaneously, as high-volume pumps cannot achieve significant height and high-pressure pumps cannot produce substantial volume, leading to inefficient and unstable stream formations.

Innovation Solution

The integration of two independently driven, high-pressure and high-volume pumps within the same submersible pump apparatus, allowing them to operate simultaneously and create a unique combination of very tall streams and various high-flow display spray patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a high-volume pump is used, then the water display volume is improved, but the height is reduced

Engineering Contradiction:

Improvewater display volumeVSAvoidstream height

Core Design Contradiction:

Quantity of substanceVSLength of moving object

Solution Approach 1:

The pump system is segmented into two independent pumps (high-volume pump and high-pressure pump) that operate simultaneously but independently, allowing each pump to optimize its specific function without compromising the other's performance characteristics

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Two previously separate pump systems are merged into a single integrated submersible pump apparatus, combining the high-volume pump and high-pressure pump in one housing with shared motors and control systems, enabling simultaneous operation to create combined water displays with both height and volume

Inventive Principle:

Principle #5Merging (Combining)

2Length of moving object

If a high-pressure pump is used, then the stream height is improved, but the water display volume is reduced

3Length of moving object

If thin streams are used to achieve height, then the stream height is improved, but the stream stability is reduced

Engineering Contradiction:

Improvestream heightVSAvoidstream coherence

Core Design Contradiction:

Length of moving objectVSStability of the object's composition

Solution Approach 1:

The thin high streams from the high-pressure pump are merged with the voluminous spray patterns from the high-volume pump in the same water display, creating a combined effect where the high-volume water provides stability and coherence to the overall display while the high-pressure pump creates the tall streams

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Both pumps draw from the same water source and discharge into the same display environment, creating a homogeneous water display medium where the different stream types interact and support each other's stability

Inventive Principle:

Principle #33Homogeneity
