UV Bezel Lamp Self-Cleaning Vehicle Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle display surfaces in vehicles often become contaminated with dust, fingerprints, and fluids, requiring manual cleaning which can be inefficient and ineffective, especially in autonomous vehicle environments where frequent user interaction occurs.
Innovation Solution
An interior cleaning system that includes a display with a light-sensitive coating and a bezel lamp emitting UV light, activated by a computer processor to sanitize the surface, using titanium dioxide that reacts with organic matter to break it down into water and carbon dioxide, thereby cleaning the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning with cloth and cleaning solution is used, then cleaning can be performed, but it is inefficient and requires frequent user intervention
Solution Approach 1:
The display surface performs self-cleaning through photocatalytic action. When UV light illuminates the titanium dioxide coating on the screen, it generates reactive oxygen species that automatically decompose organic contaminants without requiring manual cleaning intervention.
Solution Approach 2:
The patent replaces the mechanical cleaning system (cloth and cleaning solution application) with a photochemical cleaning system. UV light activation of titanium dioxide coating substitutes for manual mechanical cleaning actions.
2Extent of automation
If titanium dioxide coating with UV light activation is used, then automated cleaning and sanitization is achieved, but device complexity increases
Solution Approach 1:
The titanium dioxide coating serves multiple functions: it acts as a photocatalyst for cleaning, provides antimicrobial sanitation, and maintains display visibility. The UV lighting system is integrated into the existing display structure, making it multi-functional rather than adding separate dedicated systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively kills bacteria and viruses on the display surface, reducing the need for manual cleaning and maintaining a hygienic interface in vehicles, especially in autonomous modes where user interaction is frequent.
Implementation Method 1
titanium dioxide that reacts with organic matter to break it down into water and carbon dioxide
Implementation Method 2
bezel lamp emitting UV light, activated by a computer processor to sanitize the surface
Implementation Method 3
light from the lamp activates the coating to clean the surface thereof... effectively kills bacteria and viruses on the display surface
