Solution Overview

Problem

Existing floor cleaning brushes are limited in their functionality, failing to effectively clean edges or crevices, which does not meet users' requirements.

Innovation Solution

A dual-function floor cleaning brush is designed, comprising a crevice brush with a threaded head for handle connection and a floor brush with a connection groove for embedding the crevice brush, allowing for independent or combined use, with a fixing knob for easy installation and adjustment of the threaded head's angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-function floor brush is used, then the structure is simple, but it cannot effectively clean edges or crevices

Engineering Contradiction:

Improvecleaning functionalityVSAvoidbrush structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The floor cleaning brush is designed with dual functionality: the main floor brush head can clean flat surfaces, while the detachable crevice brush attachment can clean edges and corners. This multi-functionality allows a single device to perform multiple cleaning tasks that previously required separate tools.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The crevice brush is designed to be nested within or attached to the floor brush head. The crevice brush can be stored inside the floor brush head when not in use, and easily attached when needed. This nesting approach allows both brushes to be integrated into a single compact unit without significantly increasing the overall device size.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a detachable crevice brush attachment is added, then versatility is improved, but the installation and removal operation becomes more complex

Engineering Contradiction:

Improvedual-function capabilityVSAvoidattachment operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection between the floor brush and crevice brush uses a dynamic snap-fit mechanism with elastic elements. The crevice brush can be easily snapped into place and quickly removed by pressing a release button, allowing rapid attachment and detachment without complex tools or procedures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The snap-fit connection mechanism is designed to be self-aligning and self-locking. When the crevice brush is inserted, the elastic elements automatically engage the locking features without requiring precise manual alignment, and the connection securely holds the attachment in place during cleaning operations.

Inventive Principle:

Principle #25Self-service

AI summary

A dual-function floor cleaning brush comprises a crevice brush with a threaded head at the top for handle connection and a floor brush with an interior connection groove for crevice brush embedment, allowing a combination into a single entity. The top of the floor brush is movably provided with a fixing knob for clamping the crevice brush, the positioning slots are provided on both sides of the crevice brush, and positioning blocks are provided on both sides of the inner wall of the connection groove, realizing engagement between the positioning slots and the positioning blocks with the crevice brush embedded into the connection groove. The crevice brush and floor brush can be used independently or in combination, and rotating the fixing knob realizes a simple and quick operation of installing and removing the crevice brush, enabling the threaded head's angle adjustment via the turning knob.
