Solution Overview

Problem

There is a lack of apparatuses capable of conveniently measuring and analyzing the fine dust-blocking effectiveness of cosmetics under actual atmospheric conditions, as existing technologies do not provide a controlled environment to simulate real-world fine dust exposure.

Innovation Solution

An apparatus is developed to create an artificial atmospheric environment with fine dust, utilizing a chamber with multiple driving fans for dust distribution and a filter to maintain a controlled exposure, along with an analysis system that captures and compares images before and after exposure to quantify dust-blocking efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If no controlled environment apparatus is used, then measurement of fine dust-blocking effect under actual atmospheric conditions cannot be performed, but developing such an apparatus increases device complexity

Engineering Contradiction:

Improvefine dust-blocking effect measurementVSAvoidapparatus structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The apparatus is divided into distinct functional modules: a chamber for creating the dust environment, a dust supply unit for introducing fine dust particles, a wind generation unit for distributing dust uniformly, and an analysis system for measuring dust-blocking effects. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the complexity required for accurate measurement.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If multiple driving fans are used to distribute dust uniformly, then dust distribution accuracy improves, but energy consumption increases

Engineering Contradiction:

Improvedust distribution uniformityVSAvoidwind generation energy

Core Design Contradiction:

Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The wind generation unit employs multiple driving fans that can be dynamically controlled to create uniform dust distribution throughout the chamber. The fans are positioned and configured to generate airflow patterns that effectively disperse fine dust particles, achieving homogeneous distribution necessary for accurate measurement while managing energy consumption through optimized fan placement and operation.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a filter with backflow prevention is installed, then atmospheric environment control improves, but airflow resistance increases

Engineering Contradiction:

Improveatmospheric environment controlVSAvoidairflow pressure

Core Design Contradiction:

ReliabilityVSStress or pressure

Solution Approach 1:

A filter with backflow prevention functionality is installed within the chamber system to maintain controlled atmospheric conditions. The filter acts as an intermediary component that allows necessary airflow while preventing dust particle escape and blocking backflow, thereby ensuring reliable atmospheric environment control for accurate fine dust-blocking measurements without compromising the integrity of the test environment.

Inventive Principle:

Principle #24Intermediary (Mediator)
