Solution Overview

Problem

Existing hand-guided cleaning devices are limited in their ability to effectively clean surfaces of different physical characteristics, often requiring multiple devices and leading to inefficiencies and potential damage to surfaces.

Innovation Solution

A portable, hand-guided ambient surface cleaning device with a driving mechanism that includes an electric motor and gear arrangement, capable of oscillating a brushing device, which can be easily switched between different brushing devices or segments with varying cleaning characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single type of brushing device is used, then the device structure is simple, but it cannot effectively clean surfaces of different physical characteristics

Engineering Contradiction:
Improvecleaning capability for different surfacesVSAvoidbrushing device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal brushing device that can clean multiple surface types (tiles, granite, marble, concrete, wood, metal) by integrating both a roller brush and a disc brush into a single handheld device. The roller brush is suitable for flat surfaces while the disc brush is designed for joints and grooves, allowing one device to perform functions that previously required multiple separate devices.

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

2Adaptability or versatility

If multiple cleaning devices with different brushing devices are carried for different surfaces, then cleaning effectiveness is improved, but portability and storage convenience deteriorate

Engineering Contradiction:
Improvecleaning capability for different surfacesVSAvoidportability
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent combines two previously separate cleaning devices (one with a roller brush for flat surfaces and another with a disc brush for joints) into a single integrated handheld device. This merging eliminates the need to carry multiple devices, reducing overall weight and improving portability while maintaining the ability to clean both flat surfaces and joints effectively.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a conventional rotary brushing device is used, then the cleaning action is strong, but centrifugal force throws dirt particles far away causing pollution

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddirt particle dispersal
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the conventional high-speed rotary motion with an oscillating motion mechanism that moves the brushing device back and forth in a controlled manner. This oscillating action provides effective cleaning through mechanical vibration and scrubbing action while significantly reducing centrifugal force, thereby preventing dirt particles from being thrown far away and reducing environmental pollution.

Inventive Principle:
Principle #18Mechanical vibration
