Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high intensity ultraviolet light source is used for sanitization, then germicidal kill rate is improved, but surface wear increases
Solution Approach 1:
The patent implements dynamic intensity adjustment of the ultraviolet light source based on real-time detection of surface type and movement speed. The controller modifies the light intensity dynamically during operation, increasing intensity when movement speed is high or surface requires higher dosage, and decreasing intensity when surface is sensitive or movement is slow, thereby resolving the contradiction between maintaining high germicidal effectiveness and preventing surface damage
Solution Approach 2:
The system incorporates sensors that detect surface type and device movement speed, providing real-time feedback to the controller. The controller processes this feedback and adjusts the ultraviolet light intensity accordingly, creating a closed-loop control system that adapts to varying conditions to optimize both sanitization effectiveness and surface protection
2Productivity
If light intensity is increased to achieve effective sanitization, then dosage delivery is improved, but surface damage risk increases
Solution Approach 1:
The patent changes the operational parameters of the ultraviolet light source by adjusting intensity levels based on detected surface characteristics and movement speed. The controller modifies intensity parameters in real-time, allowing the system to deliver appropriate dosage for different surfaces and operational conditions while avoiding excessive intensity that would cause surface damage
3Device complexity
If fixed intensity light source is used, then device complexity is reduced, but adaptability to different surfaces and speeds deteriorates
Solution Approach 1:
The system performs self-adjustment by using its own sensors to detect surface type and movement speed, processing this information through the controller, and automatically modifying the light intensity without external intervention. This self-service capability enables the device to adapt to varying conditions while maintaining a relatively simple overall structure

AI summary
A mobile sanitizer movable across a surface to sanitize the surface. The sanitizer may comprise an ultraviolet light source that illuminates the surface and a microprocessor control. The control may adjust the light source intensity in response to a speed of the movement of the light source relative to the surface. And, for instance, the control may drive a display indicating how movement of the device relates to sanitization settings input by a user.
