Side-View Mirror Warning Indicator System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional public service vehicle lighting systems are limited in their ability to provide supplemental warning signals to pedestrians and nearby vehicles, as they primarily rely on central lighting systems that may not effectively alert traffic from the side or rear, lacking sufficient supplemental lighting on side mirrors.
Innovation Solution
A side-view mirror warning indicator system featuring a plurality of light sources, including printed LEDs behind a partially reflective surface, capable of emitting visible light patterns in Stealth, Pursuit, and Traffic Advisor modes, utilizing phosphor dyes to alter light colors and microcontrollers for sequential actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional central lighting systems are used, then the vehicle can provide warning signals, but the visibility to side and rear traffic is insufficient
Solution Approach 1:
The lighting system is segmented into multiple independent light sources distributed across different locations on the vehicle (front, rear, and side mirrors). Each light source can be independently controlled to provide targeted illumination, improving overall visibility without requiring a single complex centralized system.
Solution Approach 2:
The warning signal system is extended from traditional two-dimensional placement (front and rear of vehicle) to three-dimensional distribution by incorporating light sources in the vertical dimension on side mirrors. This multi-dimensional arrangement ensures comprehensive coverage of surrounding traffic from multiple angles simultaneously.
2Illumination intensity
If supplemental lighting is added to side mirrors, then warning visibility is improved, but the mirror design becomes more complex
Solution Approach 1:
The warning light sources are merged with the side mirror assembly, combining two previously separate functions (mirror and lighting) into a single integrated component. This eliminates the need for separate mounting structures and reduces overall system complexity despite adding lighting functionality.
Solution Approach 2:
The side mirror assembly is designed to serve multiple functions: providing rearward visibility reflection and emitting warning light signals. This multi-functional design consolidates components and reduces the need for additional dedicated warning light structures, maintaining design simplicity.
3Reliability
If traditional light bars are used, then emergency warning is effective, but the system requires bulky electronics and complex installation
Solution Approach 1:
The patent replaces traditional mechanical light bar assemblies with LED-based light sources that can be directly integrated into existing mirror housings. This substitution eliminates the need for bulky mounting structures and complex wiring harnesses, reducing electronic system requirements while maintaining warning effectiveness.
Solution Approach 2:
The lighting system uses thin-film LED technology that can be integrated into the existing mirror housing structure without requiring bulky enclosures. This allows the warning system to be implemented using the existing mirror shell, eliminating the need for additional bulky electronic housings and simplifying installation.
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
Enhances the visibility of warning signals by providing recognizable light patterns on side mirrors, increasing attention from nearby traffic and pedestrians without requiring bulky electronics, thus supplementing existing lighting systems effectively.
Implementation Method 1
a warning indicator system configured to emit visible, recognizable light signals... a plurality of light sources disposed to emit light in patterns and/or colors visible through a partially light-reflective surface
Implementation Method 2
the partially light-reflective surface is a light transmitting substrate having a coating of a reflective substance disposed on one side thereof, the coating having a thickness allowing at least a partial transmission of light therethrough
Implementation Method 3
one or more layers of a phosphor dye are interposed between the reflective coating and the printed LEDs to alter a color of light emitted by the printed LEDs
Data Source
AI summary
A warning indicator system for a vehicle side-view mirror includes light sources disposed to emit light in patterns and/or colors visible through a partially light-reflective surface. One or more processors are operatively configured to actuate the light sources in predetermined sequences defining a stealth mode, a pursuit mode, and a traffic advisor mode. The partially light-reflective surface may be a light transmitting substrate having a coating of a reflective substance provided in a thickness allowing at least a partial transmission of light therethrough. The light sources may be printed light-emitting diodes (LEDs). Disposing the light sources in desired patterns to emit desired colors on actuation in a predetermined sequence allows configuring the side mirrors to emit visible light signals indicative of the stealth mode, a pursuit mode, and a traffic advisor mode.
