Solution Overview
Problem
There is a need for a compact fluid processing module that can efficiently purify air in closed storage devices while minimizing power consumption and maintaining effective deodorization and sterilization efficiency.
Innovation Solution
The fluid processing module includes a main body with a flow channel, an absorption filter, a photocatalyst filter, and a light source unit. The flow channel has varying cross-sectional areas to adjust flow speeds, ensuring the photocatalyst filter operates within an effective range for deodorization without the need for a fan, thus reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fluid processing module is made compact, then space utilization is improved, but fluid processing efficiency and fluid processing amount per hour are reduced
Solution Approach 1:
The flow channel is designed with non-uniform cross-sectional area, creating different flow conditions in different regions. The cross-sectional area is smaller in the photocatalyst filter region to increase flow speed and improve processing efficiency, while maintaining overall compact module dimensions. This local variation in geometry allows the module to achieve high processing efficiency within a compact form factor.
2Productivity
If a fan is added to increase flow speed, then deodorization efficiency is improved, but power consumption increases
Solution Approach 1:
The flow channel geometry itself serves to control and optimize fluid flow speed without requiring external power input. By designing the channel with varying cross-sectional area, the system uses the fluid's own kinetic energy and pressure differential to achieve the required flow speeds for effective deodorization, eliminating the need for powered fans or pumps.
Solution Approach 2:
The patent replaces the mechanical fan system with a passive fluid dynamics solution. Instead of using a powered mechanical device to increase flow speed, the invention uses carefully designed channel geometry that naturally accelerates fluid flow through conservation of mass and energy principles, substituting a powered mechanical system with a passive geometric solution.

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 absorption 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.
