A fluid processing module with a main body having a flow channel, an absorption filter perpendicular to the flow direction, a photocatalyst filter parallel to the flow direction, and a light source unit emitting light to the photocatalyst filter, with varying cross-sectional areas and flow speeds to optimize deodorization and sterilization efficiency without a fan, using guide portions to adjust flow speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fluid processing module is made compact to fit restricted space in storage devices, then space utilization is improved, but fluid processing efficiency and processing amount per hour are reduced
Solution Approach 1:
The flow channel cross-sectional area is varied along the flow direction, creating dimensional changes in the flow path. The channel transitions from a first cross-sectional area to a second cross-sectional area, utilizing spatial dimensionality optimization to improve fluid dynamics within a compact volume, thereby resolving the contradiction between compact size and processing efficiency
Solution Approach 2:
The patent changes the geometric parameters of the flow channel by varying the cross-sectional area along the flow direction. This parameter modification optimizes fluid velocity distribution and processing efficiency within the constrained module volume, addressing the trade-off between compactness and productivity
2Productivity
If the flow channel cross-sectional area is reduced to increase flow speed for better deodorization efficiency, then deodorization efficiency is improved, but the module occupies more space
Solution Approach 1:
The flow channel is designed with non-uniform cross-sectional area distribution, creating local quality variations along the flow path. Specific regions have optimized cross-sectional areas to achieve appropriate flow speeds for effective photocatalytic deodorization, while maintaining overall compact module dimensions through localized rather than global dimensional changes

AI summary
A fluid processing module includes a main body having a flow channel extending in a first direction therein and allowing a fluid to flow therein, an adsorption filter disposed perpendicular to the first direction inside the main body, a photocatalyst filter disposed parallel to the first direction inside the main body, and a light source unit disposed inside the main body and emitting light towards the photocatalyst filter. The fluid flows at a first flow rate in the region of the flow channel having a first cross-sectional area. The fluid flows at a second flow rate in the region of the flow channel having a second cross-sectional area. The photocatalyst filter has effective deodorizing efficiency when the fluid flows at the second flow rate.
