Solution Overview

Problem

Conventional submersible pump arrangements face challenges in portability and storage due to separate configurations of the pump and control housing, which complicates transportation and wastes storage space.

Innovation Solution

A battery transport system (BTS) with a pump housing and a control housing connected via a flexible connection and locking features, allowing easy coupling and decoupling for improved portability and storage efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the submersible pump and control housing are kept in separate configurations, then ease of operation is improved, but portability deteriorates due to difficulty in transporting them together

Engineering Contradiction:
Improveease of operationVSAvoidportability
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The system is divided into separable components (pump housing and control housing) that can be independently handled during operation but coupled together for transport, allowing both ease of operation and improved portability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pump housing and control housing are merged into a single transport unit through the locking mechanism, enabling them to be moved together as one assembly while maintaining operational separability

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the submersible pump and control housing are kept in separate configurations, then ease of operation is improved, but storage space efficiency deteriorates due to wasted storage space

Engineering Contradiction:
Improveease of operationVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The system allows operational segmentation while enabling storage consolidation, where the pump and control housing can be separated for use but locked together for compact storage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control housing is positioned to nest alongside the pump housing when coupled, creating a compact integrated unit that optimizes storage space while maintaining functional independence

Inventive Principle:
Principle #7Nested doll (Nesting)

3Length of moving object

If locking features are added to couple the pump housing and control housing, then portability is improved, but device complexity increases

Engineering Contradiction:
ImproveportabilityVSAvoiddevice complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The locking mechanism is designed to be self-operating through simple user actions (snap-fit or push-fit), automatically coupling or decoupling the housings without requiring complex tools or procedures

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking feature is extracted as a distinct, simple mechanism separate from the main pump and control housing functions, adding portability capability with minimal impact on overall device complexity

Inventive Principle:
Principle #2Taking out (Extraction)
