Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle emergency or hazard lights provide insufficient visual distinction and may desensitize drivers, and their deployment can be inappropriate or distracting when not warranted.
Innovation Solution
A device with selectively lighted segments that strobe in response to a vehicle's electrical system, including a microcontroller to control illumination and a power supply, forming a hazard symbol, and optionally wireless communication, to enhance visibility during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If standard emergency flasher lights are used, then the system is simple and energy-efficient, but the visual distinction from non-emergency lighting is insufficient
Solution Approach 1:
The patent applies periodic action by implementing a strobing illumination pattern where the emergency light alternates between on and off states at a high frequency. This creates a distinctive visual effect that differentiates emergency situations from standard flashing lights, directly addressing the insufficient visual distinction problem while maintaining relative system simplicity
Solution Approach 2:
The patent segments the illumination into multiple discrete light-emitting elements arranged in specific patterns (such as triangular configurations). This segmentation allows for more complex visual patterns and enhanced visual distinction compared to a single light source, while the modular nature of segmented LEDs keeps the system manageable in complexity
2Illumination intensity
If high visibility strobe is deployed, then visual distinction is enhanced, but driver desensitization and distraction occur when genuine emergencies do not exist
Solution Approach 1:
The patent incorporates feedback mechanisms through a microcontroller that monitors vehicle sensor data (such as collision detectors, airbag deployment status, and other emergency indicators) to determine whether actual emergency conditions exist. This feedback loop ensures the high-visibility strobe is activated only when genuine emergencies are detected, preventing driver desensitization and maintaining signal reliability
Solution Approach 2:
The system performs preliminary action by pre-programming the microcontroller with decision logic that evaluates emergency conditions before activating the strobe. This preliminary assessment prevents inappropriate activation, ensuring the high-visibility signal is reserved for genuine emergencies and maintaining its reliability
3Illumination intensity
If high visibility strobe is overused, then visibility is improved, but the driving public becomes desensitized over time
Solution Approach 1:
The feedback mechanism continuously monitors actual emergency conditions and prevents activation when no genuine emergency exists. This selective activation based on real-time feedback ensures the high-visibility strobe is used only when necessary, preventing public desensitization while maintaining maximum visibility effectiveness for actual emergencies
Solution Approach 2:
The system changes the operational parameter from frequent or continuous activation to conditional activation based on detected emergency severity and type. This parameter change in activation frequency and conditions prevents desensitization while preserving the strobe's visibility benefits for genuine emergencies
