UV Sterilization System With Marker-Based Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization systems using ultraviolet ray irradiation are ineffective for sterilizing large spaces such as rooms and factories, as they do not easily adapt to wide-ranging sterilization targets like viruses and bacteria that float in the air and adhere to surfaces, requiring cumbersome measures like air replacement or antiseptic spraying.
Innovation Solution
A sterilization system with a light source unit, horizontal and vertical angle adjustment units, and a controller that uses a marker sensor to direct ultraviolet rays across a wide area by rotating the light source unit in both directions, allowing for easy setting and adjustment of the irradiation range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a fixed sterilizer is used for sterilization, then the sterilization function is provided, but the sterilization range is limited and cannot cover wide spaces
Solution Approach 1:
The sterilizer incorporates horizontal and vertical angle adjustment units that enable the light source to rotate and change its irradiation direction dynamically. This transforms the fixed sterilizer into an adjustable system, allowing the sterilization range to be expanded to cover wide spaces while maintaining operational ease through automated control
Solution Approach 2:
The control unit automatically controls the angle adjustment units to direct the light source toward markers placed by the user. The system self-adjusts its orientation based on marker positions, eliminating the need for manual complex adjustments and enabling users to easily define the sterilization range by simply placing markers
2Reliability
If air replacement or antiseptic spraying is used to sterilize spaces, then sterilization is achieved, but the workload is large and equipment changes are required
Solution Approach 1:
The invention replaces complex mechanical sterilization methods (air replacement systems, spraying equipment) with a simpler optical system. The ultraviolet light source combined with angle adjustment units and marker-based control provides effective sterilization without requiring cumbersome mechanical equipment or extensive operational procedures
Solution Approach 2:
The system changes the approach to sterilization by using adjustable angular parameters (horizontal and vertical angles) to control the light source direction. This parameter-based control allows the same device to adapt to different sterilization ranges and spaces, providing reliable sterilization effectiveness without increasing system complexity

AI summary
A sterilization system of an embodiment includes a light source unit, a horizontal angle adjustment unit and/or a vertical angle adjustment unit, and a controller. The light source unit emits ultraviolet rays in a radiating form. The horizontal angle adjustment unit adjusts a horizontal angle of the light source unit by causing rotation of the light source unit in a horizontal direction. The vertical angle adjustment unit adjusts a vertical angle of the light source unit by causing rotation of the light source unit in a vertical direction. The controller receives a marker signal transmitted from a marker via a marker sensor, controls rotation of the horizontal angle adjustment unit and/or the vertical angle adjustment unit to direct an optical axis of the light source unit to the marker, and stores a horizontal angle and/or a vertical angle of the light source unit in response to a position setting request.
