Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UV sterilizing box structures face challenges in achieving effective sterilization while maintaining a high flowrate, as they often require longer or flattened flow channels, which increase volume and flow resistance, respectively.
Innovation Solution
A UV sterilizing box structure with a round chamber and arc-shaped guiding channel, where the inlet and outlet are positioned on different sides, allowing fluid to flow spirally under inertia, increasing exposure time to UV rays and reducing flow resistance, thus enhancing sterilization efficiency and flowrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the flow channel is lengthened to prolong irradiating time, then sterilization effectiveness is improved, but the volume of the sterilizing box increases
Solution Approach 1:
The patent employs a circular chamber configuration with arc-shaped guiding channels instead of linear flow paths. This curved geometry allows fluid to spiral through the chamber, increasing the effective path length and irradiation time while maintaining a compact circular footprint, thus resolving the contradiction between prolonged irradiation and box volume.
2Duration of action of moving object
If the flow channel is flattened to decrease irradiating distance, then sterilization effectiveness is improved, but flow resistance increases and flowrate is reduced
Solution Approach 1:
The arc-shaped guiding channels provide a gradual curved path that decreases the perpendicular distance from UV sources while maintaining smooth flow transitions. This prevents flow separation and excessive resistance that would occur with abrupt flattening, thus achieving close irradiation distances without sacrificing flowrate.
Solution Approach 2:
The patent transitions from a two-dimensional flattened channel concept to a three-dimensional spiral flow path within the circular chamber. This allows the fluid to approach UV sources from multiple spatial dimensions, achieving comprehensive irradiation while maintaining adequate flow velocity through the volumetric space.

AI summary
The invention is a UV sterilizing box structure. A box body has a round chamber, an inlet, and an outlet. The round chamber is formed with an arc-shaped guiding channel. A UV light module is disposed on a side of the box body. An external fluid enters the round chamber via the inlet and spirally flows through an inside of the round chamber along the arc-shaped guiding channel so as to make the fluid in the box body generate a flow with a specific direction and stay for enough time to be sufficiently irradiated by UV rays. Thereby, a better effect of sterilization may be obtained.
