Luminant Trim for Motor Vehicle Door Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for enhancing vehicle visibility in dim lighting conditions, such as fog or darkness, are inadequate as they either complicate installation, are expensive, or fail to illuminate the car door effectively when closed or open, particularly with tinted windows.
Innovation Solution
A luminant trim is applied to the car door and window frame, using reflective tape or electrically powered LEDs that can be easily integrated into the vehicle's electrical system, ensuring visibility both inside and outside the vehicle, regardless of the window's position, and providing various signaling capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective material is placed in a groove on the vehicle body, then visibility in dim lighting is improved, but the installation complexity increases and the reflective material is exposed to ultraviolet deterioration
Solution Approach 1:
The invention extracts the reflective material from complex grooves and relocates it to a simple adhesive strip that can be directly applied to the vehicle body surface, eliminating the need for groove formation while maintaining visibility enhancement
Solution Approach 2:
The patent uses inexpensive adhesive-backed reflective strips that can be easily applied and replaced, sacrificing the durability of permanent installations for ease of installation and cost-effectiveness
2Illumination intensity
If taillights are added to door edges, then visibility when doors are open is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The invention uses reflective materials that passively return light from existing headlights without requiring additional power sources, control systems, or complex manufacturing, allowing the vehicle to illuminate itself using ambient light
Solution Approach 2:
The reflective strips serve multiple functions: enhancing visibility when doors are open, marking vehicle contours, and providing safety signaling, all through a single simple component
3Illumination intensity
If luminant component is applied to window frame, then visibility through window is improved, but the cost and installation complexity increase
Solution Approach 1:
The invention extracts the luminant function from complex integrated systems and implements it through simple adhesive strips that can be independently applied to the window frame, separating the illumination function from the window assembly
Solution Approach 2:
The patent uses flexible adhesive-backed reflective strips that can be easily conformed to and applied on the window frame surface, providing simplicity in both design and installation
