Solution Overview

Problem

Current cleaning apparatuses are unable to effectively store and apply two types of detergents required for cleaning wool or silk clothes, which necessitate different cleaning methods for removing light contaminants and local stains.

Innovation Solution

A cleaning apparatus with a first cleaner for spraying a first detergent and a second cleaner for discharging a second detergent, equipped with a vibration unit that applies physical impacts when the second detergent is sprayed onto stained areas, allowing for the storage and application of both detergents in a single device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate detergent-spraying devices are used to store and spray two different kinds of detergent, then the capability to perform both types of cleaning (light contaminants and local stains) is improved, but the device complexity increases

Engineering Contradiction:
Improvecapability to perform both types of cleaningVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines two separate detergent-spraying devices into a single integrated cleaning device. The first cleaner container stores and sprays detergent for light contaminants, while the second cleaner container stores and discharges detergent for local stains. Both cleaning functions are merged into one device, reducing the need for multiple separate devices while maintaining the capability to perform both types of cleaning.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cleaning device is designed with multi-functionality to handle both light contaminant removal and local stain elimination. By incorporating two distinct detergent storage and application systems within a single device, it serves multiple cleaning purposes that previously required separate specialized devices.

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

2Device complexity

If a single apparatus is used to store and spray two kinds of detergent, then the device complexity is reduced, but the capability to effectively apply different detergents for different cleaning purposes deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidcapability to apply different detergents
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The single cleaning device is segmented into two independent cleaner containers, each dedicated to storing and applying a specific type of detergent. The first cleaner handles light contaminant removal detergent, while the second cleaner handles local stain removal detergent. This segmentation allows each detergent to be applied independently without contamination or mixing, maintaining the effectiveness of both cleaning functions within a unified device structure.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the second cleaner discharges second detergent without vibration, then the device complexity is reduced, but the effectiveness of eliminating local stains deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoideffectiveness of eliminating local stains
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The second cleaner incorporates a vibration unit that vibrates the cleaner container when discharging the second detergent for local stain removal. This mechanical vibration enhances the discharge effectiveness by creating physical impacts that help the detergent penetrate and remove stubborn stains more efficiently, thereby improving the reliability of stain elimination without significantly increasing overall device complexity.

Inventive Principle:
Principle #18Mechanical vibration

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables convenient storage and application of two detergents, enhancing the capability to remove local stains by applying physical impacts during the cleaning process.

Implementation Method 1

a vibration unit for vibrating the second cleaner when the second cleaner discharges the second detergent, thereby discharging the detergent to a stained portion, which requires local washing, while applying physical pressure thereto

Methodology Applied
Scientific EffectVibration: Vibration
