Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency flasher systems in vehicles are insufficiently visible and not always deployable during emergencies, leading to safety hazards, and there is a need for enhanced visual communication to alert other drivers without manual activation.
Innovation Solution
A microcontroller-controlled system that operates vehicle lights in both flashing and strobing modes, with a strobe activation switch to enhance visibility by increasing the flash rate and providing an indicator light and audible signals for automatic deployment during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional hazard flasher switches are used, then the system is simple and easy to operate, but the visibility and attention-grabbing effectiveness is insufficient
Solution Approach 1:
The patent changes the operating parameters of the lighting system by introducing multiple flash rates (slow, fast, strobe) controlled by a microcontroller. This allows the same lighting components to provide enhanced visibility through variable flash patterns without requiring additional physical light sources or complex mechanical structures.
Solution Approach 2:
The patent replaces traditional mechanical flasher switches and timing mechanisms with an electronic microcontroller-based system. This substitution enables precise control over flash rates and patterns while reducing mechanical wear and improving reliability, thereby enhancing visibility without proportionally increasing mechanical complexity.
2Reliability
If hazard flashers are deployed manually, then the system remains simple, but occupants may be injured or unable to deploy them when needed most
Solution Approach 1:
The patent implements preliminary action by having the system automatically detect crash conditions and activate hazard lights without requiring manual intervention. Sensors continuously monitor for crash events, and upon detection, the microcontroller immediately triggers appropriate lighting patterns, ensuring emergency signals are deployed reliably even when occupants are injured or incapacitated.
Solution Approach 2:
The system performs self-service by automatically detecting emergencies and activating hazard lights without human intervention. The microcontroller monitors sensor inputs and autonomously controls the lighting system, making the system self-sufficient in detecting and responding to emergency conditions, thereby improving reliability without requiring constant manual operation.
3Speed
If faster flash rates are used to improve visibility, then attention-grabbing effectiveness increases, but the system becomes more complex
Solution Approach 1:
The patent applies dynamics by making the flash rate variable rather than fixed. The microcontroller dynamically adjusts between slow flash, fast flash, and strobe modes based on operational conditions and user input, allowing the system to optimize visibility and attention-grabbing effectiveness while maintaining manageable complexity through software control.

AI summary
A system includes a microcontroller that controls illumination of a plurality of vehicle lights that are operable in a flashing state wherein the plurality of lights operate as hazard flashers visible on a front and rear of a vehicle and a strobing state wherein the plurality of lights operate as strobing lights visible on the front and rear of the vehicle. The system includes a strobe activation switch that provides a signal to the microcontroller to operate the plurality of vehicle lights in the second strobing state. The microcontroller operates the plurality of vehicle lights in the first hazard flasher state in response activation of an existing hazard flasher switch. The strobing state has a flash rate that is perceptibly faster than a flash rate of the flashing state.
