Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate pool cleaning tools are purchased for different cleaning tasks, then cleaning effectiveness for specific areas is improved, but cost and storage space requirements increase

Engineering Contradiction:
Improvecleaning effectiveness for specific areasVSAvoidnumber of tools
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The pool cleaning assembly is designed as a universal multi-functional tool that can perform multiple cleaning tasks through interchangeable components. The main body can accommodate different brush heads (corner brush head, tile brush head, standard brush head) and handle configurations, allowing a single tool to replace multiple specialized tools for different pool areas including corners, tiles, and general surfaces.

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

Solution Approach 2:

The pool cleaning assembly is divided into separable modules including a main body, interchangeable brush heads, and detachable handles. This segmentation allows users to configure the tool specifically for each cleaning task by attaching the appropriate brush head and handle length, thereby reducing the need to own multiple complete tools while maintaining specialized cleaning capabilities.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple specialized brushes are used for different pool areas, then cleaning precision for specific surfaces is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvecleaning precision for specific surfacesVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The assembly incorporates dynamic reconfigurability through quick-connect mechanisms that allow users to change brush heads and handles during use. The lockable connection system enables rapid transformation from one cleaning configuration to another, providing the adaptability of multiple specialized tools without requiring users to manage and store separate complex tool sets.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If a single pool brush is used for all cleaning tasks, then storage space and cost are reduced, but cleaning effectiveness for specific areas deteriorates

Engineering Contradiction:
Improvenumber of toolsVSAvoidcleaning effectiveness for specific areas
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The interchangeable brush heads are designed with local quality optimizations for specific cleaning needs. The corner brush head has bristles arranged for corner access, the tile brush head has spacing appropriate for tile gaps, and the standard brush head has dense bristles for general surfaces. This allows a single main body to achieve specialized cleaning effectiveness through locally optimized attachments.

Inventive Principle:
Principle #3Local quality

AI summary

A pool cleaning assembly kit includes a utility connector, a handle base and one or more utility tool. The utility connector includes a connecting dock and two end connectors integrally provided at two ends of the connecting dock respectively. The handle base includes a handle frame detachably connected to the utility connector and configured to be detachably connected with a handle. The one or more utility tool is configured to be detachably connected to at least one of the end connectors so as to integrally assemble with the utility connector to form a cleaning tool.
