Solution Overview

Problem

Existing surface treatment and cleaning devices lack efficiency in applying and penetrating cleaning agents, particularly in breaking up dirt and coatings on surfaces.

Innovation Solution

A portable, hand-held device with a motor-driven applicator tip and a container for a surface treatment substance, where the applicator tip vibrates upon actuation to enhance the dispersion and penetration of the cleaning agent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional applicator is used to apply cleaning agents, then the cleaning agent can be dispensed on the surface, but the penetration and dispersion effectiveness is insufficient

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidpenetration effectiveness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies mechanical vibration to the applicator tip through a motor-driven eccentric weight mechanism. When the motor rotates the eccentric weight, it generates centrifugal force that causes the applicator tip to vibrate at high frequency. This vibration enhances the dispersion and penetration of the cleaning agent into the surface, breaking up dirt and coatings more effectively than static application methods.

Inventive Principle:
Principle #18Mechanical vibration

2Ease of operation

If a portable hand-held device is designed, then ease of operation is improved, but device complexity increases due to adding motor and vibration mechanism

Engineering Contradiction:
ImproveportabilityVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent nests the motor and eccentric weight mechanism within the handle of the applicator device. The motor is housed in a motor housing that is integrated into the handle structure, and the eccentric weight is positioned inside the motor assembly. This nested arrangement allows the vibration-generating components to be compactly integrated without significantly increasing the external dimensions or compromising portability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If vibration is added to enhance cleaning effectiveness, then penetration and dispersion improve, but energy consumption increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmotor energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic vibration through the motor-driven eccentric weight system. The motor rotates the eccentric weight at controlled speeds, creating periodic centrifugal forces that generate vibration. This periodic action allows the cleaning agent to be applied with intermittent vibratory enhancement, rather than continuous high-energy vibration, thereby reducing overall energy consumption while maintaining effective penetration and dispersion during the application phase.

Inventive Principle:
Principle #19Periodic action
