Solution Overview

Problem

Conventional vacuum cleaners face issues with hair-like foreign materials getting wound around the brush, requiring frequent cleaning and reducing the cleaning cycle efficiency.

Innovation Solution

A vacuum cleaner design featuring a brush with cylindrical drum portions, protruding blades, and a grinder with curved fan-shaped grinding blades that grind and collect hair-like materials, extending the cleaning cycle by efficiently managing hair-like debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a brush rotates to sweep up foreign materials on the floor, then cleaning effectiveness is improved, but hair-like foreign materials get wound around the brush requiring frequent cleaning

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning cycle duration
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the problematic hair-like foreign materials from the brush surface by introducing a dedicated removal mechanism. The brush design includes special structures that actively remove wound hair materials during rotation, separating the cleaning function from the hair accumulation problem, thereby extending the cleaning cycle without reducing cleaning effectiveness

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The brush is designed to self-maintain during operation through built-in hair removal structures. As the brush rotates, these structures automatically remove wound hair materials, allowing the brush to service itself and extend its cleaning cycle without external intervention or frequent manual cleaning

Inventive Principle:
Principle #25Self-service

2Productivity

If a brush rotates to collect foreign materials, then foreign materials are effectively gathered, but the brush requires frequent cleaning maintenance

Engineering Contradiction:
Improveforeign material collection efficiencyVSAvoidbrush maintenance frequency
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The brush incorporates self-maintaining structures that automatically remove hair-like foreign materials during rotation. This self-service capability reduces maintenance frequency while preserving foreign material collection efficiency, as the brush continuously cleans itself during operation without requiring external intervention

Inventive Principle:
Principle #25Self-service

3Device complexity

If conventional brush design is used, then simple structure is maintained, but hair-like materials wind around requiring frequent cleaning

Engineering Contradiction:
Improvebrush structure simplicityVSAvoidcleaning cycle
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent extracts the hair removal function from the basic brush structure by adding dedicated removal structures. This separation allows the brush to maintain relative structural simplicity while incorporating the necessary hair removal capability, thereby extending the cleaning cycle without significantly increasing device complexity

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Disclosed herein is a vacuum cleaner including a brush to rotate and collect foreign materials on the floor, and a grinder to grind the foreign materials collected through the brush. Since the hair-like foreign materials wound around the brush are grinded and cut by the grinders, a cleaning cycle of the brush can be extended.
