Solution Overview
Problem
Existing strong-UV lights for sterilization and disinfection face issues such as low sterilization efficiency, complex structure, large volume, heavy weight, installation difficulties, and high costs, particularly in ventilation and horizontal illumination UV lights.
Innovation Solution
The germicidal device incorporates a circular UV light source with a grating component to limit UV emission to horizontal directions, combined with a fan and ventilation holes for improved air circulation and sterilization efficiency, resulting in a compact, lightweight, and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ventilation UV lights are used to improve safety and enable air sterilization, then safety performance is improved, but sterilization efficiency decreases and device volume increases
Solution Approach 1:
The device segments UV light emission into multiple directional outlets (upward, downward, and lateral) rather than single-direction emission. This allows simultaneous achievement of upper space sterilization (like horizontal illumination) and air circulation sterilization (like ventilation lights), resolving the contradiction between safety and sterilization efficiency
Solution Approach 2:
The germicidal device integrates multiple functions: it can sterilize upper space surfaces, sterilize circulating air, and provide directional UV emission. By combining features of both horizontal illumination and ventilation lights, it achieves multi-functionality that resolves the trade-off between safety and efficiency
2Productivity
If fan power and light cavity are increased to improve air ventilation efficiency, then sterilization efficiency is improved, but device volume and weight increase
Solution Approach 1:
The device adds vertical UV emission dimensions (upward and downward outlets) in addition to lateral emission. This multi-dimensional approach expands sterilization coverage without requiring increased fan power or larger light cavity volume, thus improving efficiency without increasing weight
3Productivity
If large-power UV light sources are used to expand sterilization scope, then sterilization efficiency is improved, but device complexity and cost increase
Solution Approach 1:
Instead of using a single large-power UV light source, the device segments UV emission into multiple directional outlets with separate control. This segmentation allows flexible sterilization coverage adjustment and simplifies the overall system structure while maintaining extensive sterilization scope
