Photocatalyst Airflow Layout for Thin Wall-Mounted Deodorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deodorization apparatuses using photocatalyst carriers increase in size due to increased airflow path cross-sectional area, making them unsuitable for thin installations, such as wall mounting.
Innovation Solution
A deodorization apparatus design featuring a thin configuration with a photocatalyst unit between partition walls, a centrifugal blower positioned opposite the partition wall, and a light source adjacent to the second main wall, allowing air to pass through in a direction from the second main wall to the first main wall, with a light shielding wall to prevent direct light exposure.

Engineering Contradiction Analysis
1Productivity
If the area of the photocatalyst carrier is increased to improve air purification efficiency, then the cross-sectional area of the airflow path increases, but the deodorization apparatus increases in size making it unsuitable for thin installations
Solution Approach 1:
The airflow path is configured to extend in the thickness direction of the apparatus rather than expanding in planar area. The first and second partition walls create a flow path that moves air from the first main wall through the photocatalyst carrier to the second main wall, utilizing the thickness dimension to achieve efficient air purification without increasing the overall footprint or cross-sectional area of the apparatus.
2Length of stationary object
If a centrifugal blower is positioned opposite the partition wall to reduce thickness, then the apparatus achieves a thin configuration, but the airflow path configuration becomes more complex
Solution Approach 1:
The internal space is divided into multiple sections by the first and second partition walls, which are selectively connected to the first and second main walls. This segmentation allows the centrifugal blower to be positioned opposite the partition wall while maintaining a structured airflow path that moves air through the photocatalyst carrier in a controlled manner, reducing thickness without excessive complexity.
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 apparatus achieves a compact size suitable for wall mounting while maintaining effective air purification through the use of a plate-shaped photocatalyst carrier and a flat centrifugal blower, ensuring efficient airflow and reduced thickness.
Implementation Method 1
A deodorization apparatus (air purifier) for decomposing odor components in air by a photocatalyst is used
Implementation Method 2
a centrifugal blower disposed opposite to the photocatalyst unit with respect to the second partition wall... the centrifugal blower having a suction port that opens toward the first main wall and a discharge port that opens on a side facing away from the second partition wall
