Solution Overview

Problem

Conventional pool brushes are inadequate for cleaning irregularly shaped swimming pools, spa pools, and fountain pools due to their inability to efficiently clean irregular corners, gaps, steps, and uneven surfaces.

Innovation Solution

A pool brush assembly with a detachable handle and multiple replaceable brush heads, allowing for customizable configurations to accommodate different cleaning tasks, including the ability to detach and use brush heads independently for specific cleaning needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional pool brush with fixed brush head is used, then the structure is simple, but it cannot efficiently clean irregular corners, gaps, steps, and uneven surfaces

Engineering Contradiction:
Improvecleaning capability for irregular surfacesVSAvoidbrush structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pool brush is divided into separate modular components: a main brush body and detachable round end brush heads. The round end brush heads can be removed from the main brush body and used independently, allowing users to select the appropriate brush configuration for different cleaning tasks - either the main brush body for flat surfaces or the round end brush heads for corners and irregular areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pool brush assembly is designed to perform multiple cleaning functions through a single device. The main brush body can clean flat pool surfaces, while the detachable round end brush heads can clean corners, gaps, steps, and uneven surfaces. This multi-functional design eliminates the need for multiple separate brushes.

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

2Adaptability or versatility

If multiple separate brushes are carried for different cleaning tasks, then all cleaning needs are covered, but it increases the number of items to carry and manage

Engineering Contradiction:
Improvecleaning task coverageVSAvoidnumber of brush items
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Multiple brush functions are merged into a single pool brush assembly. The main brush body and round end brush heads are combined in one detachable system, allowing users to carry only one item instead of multiple separate brushes while still covering all cleaning needs.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pool brush assembly serves as a universal cleaning tool that can handle various pool surfaces and geometries. By integrating multiple brush configurations into one device, it replaces the need for multiple specialized brushes.

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

3Ease of operation

If a single brush configuration is used for all pool areas, then the device is simple to use, but it cannot effectively clean corners, gaps, steps, and irregular shapes

Engineering Contradiction:
Improvebrush usage simplicityVSAvoidcapability for irregular area cleaning
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The brush system is segmented into a main brush body and detachable round end brush heads. Users can easily switch between configurations by simply attaching or detaching the round end brush heads, maintaining operational simplicity while enabling effective cleaning of irregular areas.

Inventive Principle:
Principle #1Segmentation
