Solution Overview
Problem
Typical air conditioners are limited in air purification as they only filter pollutants and do not completely remove them, leading to re-emission during filter replacement and inefficiency in large-scale applications.
Innovation Solution
A fluid treatment device incorporating a photocatalytic filter and a light source unit that physically and chemically purifies air by using UV light to activate photocatalytic materials, such as titanium dioxide, to decompose pollutants and sterilize air, with a frame and light source support member configuration optimized for maximum irradiance and area coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical filter is used to remove air pollutants, then the structure is simple and cost-effective, but the pollutants are not completely removed and may spread back during filter replacement
Solution Approach 1:
The patent combines a photocatalytic filter with a light source unit into an integrated air treatment device. The filter and light source are coupled together such that the light source is positioned to emit light toward the photocatalytic filter, creating a unified system that performs both filtration and photocatalytic decomposition, thereby improving pollutant removal completeness while maintaining reasonable device complexity
Solution Approach 2:
The patent introduces a photocatalytic filter as an intermediary between the light source and the air pollutants. The photocatalytic material on the filter surface acts as a mediator that, when activated by light, decomposes pollutants into harmless substances, enabling complete pollutant removal without simply trapping them in the filter
2Illumination intensity
If the light source is positioned close to the photocatalytic filter to maximize irradiance, then the photocatalytic efficiency is improved, but the light source may overheat the filter or create safety issues
Solution Approach 1:
The patent makes the distance between the light source and the photocatalytic filter adjustable rather than fixed. The light source support member can be positioned at different distances from the filter, allowing optimization of light irradiance while preventing excessive heat buildup, thus dynamically balancing photocatalytic efficiency with temperature control
Solution Approach 2:
The patent changes the parameter of light source-to-filter distance to optimize system performance. By adjusting this distance parameter, the system achieves sufficient light irradiance for effective photocatalysis while maintaining the filter temperature within safe operating limits, avoiding overheating and safety issues

AI summary
A fluid treatment device includes a photocatalytic filter for deodorizing and sterilizing a fluid; a frame for fixing the photocatalytic filter; and a light source unit coupled to the frame. The light source unit includes a light source support member and a light emitting diode, which is provided on the light source support member so as to emit light at the photocatalytic filter. The frame and the light source support member are coupled in a form that separates the photocatalytic filter from the light emitting diode.
