Solution Overview
Problem
Current air cleaning technologies face challenges in achieving effective deodorization and sterilization of indoor air, particularly in efficiently removing contaminants and pollutants, which affects air quality and well-being.
Innovation Solution
An air cleaning module comprising a filter, a fan, a light source unit, and a guide structure, where the light source unit emits sterilizing light adjacent to the filter, and a guide structure directs airflow to enhance the interaction between the light and contaminants, improving deodorization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional air cleaner without a guide structure is used, then the device complexity is reduced, but the deodorization efficiency and light-contaminant interaction are insufficient
Solution Approach 1:
The housing is divided into a first space for fluid passage and a second space without fluid passage, separated by the guide structure. This segmentation allows the light source unit to be positioned in the fluid passage space where it can effectively interact with contaminants while maintaining a relatively simple overall device structure.
Solution Approach 2:
The guide structure acts as an intermediary component between the fan and the filter, creating a designated fluid passage path that directs airflow through the light source unit. This intermediary structure enables effective light-contaminant interaction without requiring complex redesign of the entire air cleaning system.
2Reliability
If the light source unit is positioned away from the filter, then the sterilization function is improved, but the interaction between light and contaminants is reduced
Solution Approach 1:
The guide structure extends in the fluid passage direction, creating a three-dimensional fluid passage space that allows the light source unit to be positioned adjacent to the filter while maintaining effective interaction distance. This dimensional arrangement enables both sterilization and deodorization functions to operate simultaneously at optimal levels.
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
The air cleaning module significantly enhances deodorization efficiency by ensuring effective interaction between the light and contaminants, leading to improved air purification and sterilization, as demonstrated by increased removal rates of acetaldehyde and organic materials.
Implementation Method 1
The light source unit is provided between the fan and the filter to provide a light having a wavelength to sterilize a contaminant source in the fluid
Implementation Method 2
The filter is a photocatalytic filter, and the light source unit provides the light to the photocatalytic filter to react with the photocatalytic filter
