Vehicle Hazard Light Strobing Interface for Automatic Emergency Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle hazard lights, such as those based on decades-old blinker technology, are insufficiently visible during emergencies and often not deployed when needed, posing a safety risk and failing to provide clear visual communication to other drivers.
Innovation Solution
A system that integrates a strobing circuit with existing vehicle wiring harnesses to enhance hazard lights, allowing for faster strobing cycles and directional signaling, activated by existing vehicle flasher switches or safety system notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional blinker technology is used for hazard lights, then the system is simple and compatible with existing wiring, but the visibility and attention-grabbing capability is insufficient
Solution Approach 1:
The patent combines traditional hazard light functionality with strobing capability by integrating a strobing circuit that interfaces with existing vehicle wiring harnesses and flasher modules. This merging allows the system to maintain compatibility with legacy systems while adding enhanced visibility through strobing effects, resolving the contradiction between simplicity and visibility.
Solution Approach 2:
The system dynamically adjusts the lighting pattern from traditional steady blinking to enhanced strobing patterns with faster cycle rates. The strobing circuit modifies the temporal characteristics of the light output, creating more attention-grabbing visual signals while maintaining the same basic system architecture, thus improving visibility without proportionally increasing complexity.
2Speed
If faster strobing cycles are implemented, then visibility and attention-grabbing capability increase, but the cycle rate exceeds traditional blinker speeds
Solution Approach 1:
The patent introduces a strobing circuit as an intermediary component between the traditional flasher module and the hazard lights. This intermediary handles the complex timing and strobing control, allowing the traditional flasher module to continue operating at its designed speed while the strobing circuit imposes additional faster cycling on the light output, thus achieving high-speed strobing without overwhelming the entire control system.
Solution Approach 2:
The system segments the control function into two independent parts: the traditional flasher module that provides basic blinking control, and the added strobing circuit that provides enhanced faster cycling. This segmentation allows each component to operate within its optimal performance range without requiring complete system redesign, managing the complexity of high-speed strobing through functional division.
3Extent of automation
If hazard lights are activated manually by occupants, then deployment control is simple, but automatic deployment during emergencies is not achieved
Solution Approach 1:
The system incorporates automatic deployment capability where the hazard lights can be activated automatically by the vehicle's safety systems without requiring manual intervention by occupants. The strobing circuit interfaces with existing safety system notifications to trigger automatic hazard light deployment during emergencies, while still preserving the option for manual activation, thus achieving automation without completely replacing simple operation.
4Loss of information
If strobing hazard lights are used, then visibility and communication clarity improve, but energy consumption increases
Solution Approach 1:
The system uses periodic strobing action instead of continuous illumination to achieve enhanced communication clarity. By cycling the lights on and off at high speed, the system creates attention-grabbing visual signals that improve information transmission to other drivers, while consuming less energy than continuous high-intensity lighting would require, thus resolving the contradiction between communication clarity and energy consumption.

AI summary
A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.
