Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultraviolet (UV) air sterilization systems face inefficiencies due to the need to operate in vacant spaces to avoid UV irradiation on humans, limiting their effectiveness and requiring enclosed sterilization environments, which slows down the air sterilization process by relying on natural convection.
Innovation Solution
The UV air germicidal lamp system incorporates a base frame with an air inlet and outlet, a fan, and a UV germicidal module with a lamp module, where the UV germicidal module is designed to prevent UV leakage, allowing operation in spaces with humans by using a fan to accelerate air convection and a duct system that retains air within the UV lamp module for extended exposure, enhancing sterilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If UV lamps are operated in a vacant space to avoid UV irradiation on human body, then safety is improved, but sterilization efficiency deteriorates
Solution Approach 1:
The system divides the space into a UV irradiation zone (cavity) and a safe zone by using the duct system as a physical barrier. Air is segmented and channeled through the ducts, allowing UV lamps to operate continuously without direct exposure to humans while still achieving sterilization of the air passing through the irradiation zone.
Solution Approach 2:
The duct system acts as an intermediary between the UV lamps and the surrounding environment. It allows UV radiation to sterilize air within the duct while preventing direct UV exposure to humans outside the duct system, enabling continuous operation without requiring vacant spaces.
2Object-affected harmful factors
If natural convection is used for air sterilization in an enclosed space, then safety is improved, but sterilization speed deteriorates
Solution Approach 1:
The system uses a fan to create forced air convection, replacing natural convection. The fan drives air through the duct system and UV irradiation zone at controlled speeds, significantly increasing the sterilization rate while maintaining safety by confining UV radiation within the duct system.
3Productivity
If a duct system is used to retain air within the UV lamp module, then sterilization efficiency is improved, but device complexity increases
Solution Approach 1:
The duct system serves multiple functions: it channels air through the UV irradiation zone, contains UV radiation to prevent human exposure, and creates air retention for enhanced sterilization. By integrating these functions into a single component system, the patent achieves improved sterilization efficiency without proportionally increasing complexity.
