Solution Overview
Problem
UV sterilization apparatuses face challenges in maintaining effective sterilization performance due to increased distance from the emission source and degradation in high-temperature environments, particularly in enclosed spaces like vehicle passenger compartments.
Innovation Solution
A UV sterilization apparatus with a movable sterilization unit and a heat sink, controlled by a motor and pulley system, allows for positioning adjustment and enhanced heat dissipation by opening a communication path with the outside environment to manage temperature and improve sterilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sterilization unit is positioned in an enclosed space, then sterilization coverage is improved, but heat dissipation deteriorates
Solution Approach 1:
The sterilization unit is designed to be movable between an extended position (outside the enclosure) and a retracted position (inside the enclosure). The driving unit enables dynamic positioning adjustment, allowing the system to optimize between sterilization coverage and heat dissipation based on operational requirements
Solution Approach 2:
The sterilization unit can be extracted from the enclosed space during operation. When heat dissipation becomes critical, the unit is moved outside the enclosure through the driving mechanism, separating the heat-generating component from the confined thermal environment
2Reliability
If the sterilization unit is placed close to the target, then sterilization effectiveness is improved, but heat accumulation worsens
Solution Approach 1:
The system dynamically adjusts the position of the sterilization unit using the driving unit. During sterilization operations, the unit is positioned close to the target for maximum effectiveness. When heat accumulation reaches critical levels, the unit is automatically repositioned outside the enclosure to dissipate heat
3Reliability
If the sterilization unit operates continuously, then sterilization performance is maintained, but heat dissipation becomes insufficient
Solution Approach 1:
The sterilization unit is extracted from the enclosed space for heat dissipation purposes. The driving unit enables the unit to move outside the enclosure when thermal management is required, allowing continuous operation by periodically removing the heat source from the confined space
Solution Approach 2:
The system implements periodic positioning adjustments where the sterilization unit alternates between operating inside the enclosure and dissipating heat outside. This periodic movement allows continuous sterilization performance while managing heat accumulation through cyclical repositioning
