Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing germicidal UVC lighting systems face challenges in delivering evenly distributed doses of radiation, leading to potential over-exposure or under-exposure of microorganisms, especially with non-directional beams and obstacles blocking the radiation, which can result in ineffective disinfection and material damage.
Innovation Solution
The germicidal lighting system employs directional UVC radiation beams controlled by mechanical devices like robotic arms or swingable light fixtures, and AI-controlled systems to ensure even intensity distribution, using sensors and adjustable light sources to deliver precise doses close to the germicidal threshold, avoiding over-exposure and ensuring effective disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If diffusing non controllable scattering UVC beams are used, then the coverage area is large, but the dose distribution is uneven causing over-exposure or under-exposure
Solution Approach 1:
The system divides the UVC radiation into multiple controllable directional beams using separate light sources and optical elements, allowing independent control of each beam's intensity and direction to achieve uniform dose distribution across the coverage area
Solution Approach 2:
The system employs movable components including robotic arms and swingable light fixtures that can dynamically adjust the position and orientation of UVC beams to adapt to different surface geometries and maintain uniform dose distribution
2Reliability
If high intensity UVC beams are used to ensure germicidal effectiveness, then the germicidal dose is sufficient, but material damage and color fade occur
Solution Approach 1:
The system incorporates sensors and control systems that monitor the actual dose received by different areas and adjust the beam intensity in real-time to maintain the threshold for germicidal effectiveness while preventing over-exposure and material damage
Solution Approach 2:
The system dynamically adjusts UVC beam parameters including intensity, duration, and spatial distribution to deliver the minimum effective dose for germicidal activity while avoiding excessive radiation that would cause material degradation
3Device complexity
If stationary fixed light fixtures are used, then the device complexity is low, but the adaptability to varied surfaces and obstacles is insufficient
Solution Approach 1:
The system replaces fixed stationary fixtures with movable robotic arms and swingable light fixtures that can dynamically reposition themselves to accommodate varied surface geometries, angles, and obstacles while maintaining control over UVC beam delivery
Solution Approach 2:
The system employs universal positioning mechanisms and adjustable optical elements that enable the same device to effectively treat diverse surfaces including flat areas, vertical surfaces, curved surfaces, and areas around obstacles

AI summary
A germicidal lighting system may include a directional germicidal light source for emitting a beam of germicidal light. The directional germicidal light may be mounted movably with respect to a structure, which can in turn be movable. The directional germicidal light source may be moved and oriented relative to surfaces to be irradiated using the motion relative to the structure or the motion of the structure. The directional germicidal light source may be moved to scan a surface to smooth out dosage. Dosage may also be controlled using sensors to monitor the dosage applied.
