UV Sterilization Chamber With Electrostatic Spray for Curved Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization devices fail to effectively disinfect articles with curved shapes due to ultraviolet light not reaching shaded portions, leading to insufficient disinfection.
Innovation Solution
A sterilizing device with a cover and wall portion featuring micro nozzles for electrostatically spraying water and light-emitting elements for ultraviolet irradiation, enhancing disinfection by reaching shaded areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet light is used for sterilization, then sterilization can be performed, but shaded portions of curved articles cannot be effectively disinfected
Solution Approach 1:
The patent combines ultraviolet light irradiation with electrostatic water spraying in a single sterilization system. The water droplets generated by electrostatic spraying serve as a medium that can reach shaded areas while carrying disinfectant, complementing the ultraviolet light's sterilization effect and overcoming its limitation of unable to reach curved surfaces.
Solution Approach 2:
Water droplets generated by electrostatic spraying act as an intermediary carrier that can penetrate into shaded portions of articles. These fine water droplets disperse throughout the sterilization chamber and deposit on surfaces that ultraviolet light cannot directly reach, thereby mediating the disinfection process in hard-to-reach areas.
2Device complexity
If only ultraviolet light irradiation is used, then the sterilization device structure is simple, but sterilization efficiency is insufficient for curved articles
Solution Approach 1:
The patent merges ultraviolet light irradiation functionality with electrostatic water spraying functionality into an integrated sterilization system. This combination maintains structural simplicity while significantly enhancing sterilization efficiency by addressing the limitations of ultraviolet light alone through the addition of water-based disinfection that can reach all surfaces including curved ones.
