Solution Overview

Problem

Existing vacuum cleaners require multiple brush heads for different surfaces, leading to increased purchase costs and complexity, as well as inefficient dust removal due to large spacing between cleaning members on the brush head, which interferes with dust collection on carpets.

Innovation Solution

A roller brush with closely arranged cleaning slots, allowing for effective cooperation between cleaning members, including a hard bristle, strip-shaped, and soft bristle configuration, and cyclone grooves to enhance dust and hair removal, reducing the need for multiple brush heads and improving cleaning efficiency across various surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple brush heads are used for different surfaces, then cleaning performance on various surfaces is improved, but purchase cost and device complexity increase

Engineering Contradiction:

Improvecleaning performance on various surfacesVSAvoidnumber of brush heads

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The roller brush integrates multiple cleaning members with different properties (soft bristles for hard floors, hard bristles for carpets) into a single universal brush head, eliminating the need for multiple specialized brush heads while maintaining effective cleaning performance across different surface types

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines cleaning members of different types and hardness levels into one integrated roller brush assembly, merging the functions of what were previously separate brush heads into a single multi-functional unit that can handle both hard floors and carpets

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If cleaning members are uniformly distributed with large spacing, then manufacturing is simplified, but dust removing effects interfere with each other and cleaning efficiency decreases

Engineering Contradiction:

Improvemounting slot arrangementVSAvoiddust removing efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent applies different spacing arrangements to different groups of cleaning members: some groups have closely spaced members for intensive cleaning areas, while other groups have wider spacing, creating local variations in density that optimize both manufacturing and cleaning efficiency for different surface types

Inventive Principle:

Principle #3Local quality

3Productivity

If hard bristle brush is used for carpets, then dust embedded in carpet seams can be removed, but the brush cannot be used for hard floors due to scratching risk

Engineering Contradiction:

Improvedust removal from carpetsVSAvoidusage on hard floors

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The roller brush is segmented into multiple independent cleaning members with different properties (soft bristles, hard bristles, strip-shaped members) that can work together or independently, allowing the system to adapt to different surface types without requiring complete brush head replacement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The brush head uses composite construction with different materials and bristle types integrated into a single unit, combining the dust-removing capability of hard bristles with the floor-safe properties of soft bristles and strip members

Inventive Principle:

Principle #40Composite materials

4Ease of manufacture

If cleaning members are spaced far apart, then manufacturing and assembly are easier, but dust beaten out by one member may be beaten back into the surface by the next member

Engineering Contradiction:

Improvemounting slot spacingVSAvoiddust removal effectiveness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent implements variable spacing where certain groups of cleaning members are positioned close together to ensure dust is effectively removed and not redeposited, while other groups maintain wider spacing, creating local zones of intensive cleaning action where needed

Inventive Principle:

Principle #3Local quality

AI summary

The present disclosure discloses a roller brush, a floor brush head, a brush bristle structure, and a vacuum cleaner. The roller brush of the present disclosure includes a roller brush substrate, at least one group of first cleaning slots arranged in group are formed in the roller brush substrate, the number of first cleaning slots in each group arranged in group is at least three, and the first cleaning slots in each group are close to one another. Actions of the cleaning members do not interfere with one another, especially, during surface cleaning for a carpet and the like, dust scrabbled by the first cleaning member in one group can be effectively scraped away by the second cleaning member arranged in the same group and close to the first cleaning member and cannot be beaten into the carpet again.
