Front License Plate Deceleration Indicator for Pedestrian Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle safety systems do not effectively communicate a vehicle's deceleration or braking status to pedestrians and other vehicles in front of it, as conventional rear brake lights only inform those behind the vehicle, leading to potential safety hazards due to distracted driving and the increasing complexity of vehicle interactions.
Innovation Solution
A deceleration indication apparatus mounted on a vehicle's license plate frame, utilizing LEDs and accelerometers to visually signal deceleration or braking to pedestrians and other vehicles, with power sourced from the vehicle's battery or rear brake light system, and optionally incorporating sensors for pedestrian detection, providing a front-facing visual indication of the vehicle's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional rear brake lights are used, then those behind the vehicle are informed of braking status, but pedestrians and vehicles in front cannot detect the braking state
Solution Approach 1:
The patent applies inversion by placing brake indicator lights on the front of the vehicle instead of only on the rear. This allows pedestrians and vehicles in front to see the braking status, directly addressing the information loss problem while maintaining the original rear brake light function.
Solution Approach 2:
The patent extends the brake light information transmission from a single rearward dimension to multiple dimensions by adding front-facing indicators. This creates omnidirectional or multi-directional information dissemination, allowing braking status to be communicated to vehicles and pedestrians in various directions simultaneously.
2Reliability
If drivers pay full attention to the road, then safety is improved, but distracted driving becomes less problematic only if information is available
Solution Approach 1:
The patent implements feedback by providing real-time visual information about the vehicle's braking status to external observers. This feedback loop allows pedestrians and other drivers to adjust their behavior based on the observed braking state, improving overall system safety and reliability.
Solution Approach 2:
The front brake indicator lights serve as an intermediary that translates the internal braking state into visible external signals. This intermediary communication channel bridges the information gap between the driver's actions and the perception of pedestrians or other vehicles, enhancing safety without requiring direct driver attention.
3Device complexity
If brake light information is only transmitted to the rear, then the system is simple, but safety communication to all directions is incomplete
Solution Approach 1:
The patent segments the brake light system into separate directional components: rear brake lights for backward communication and front brake indicator lights for forward communication. This segmentation allows each component to perform its specific function independently, maintaining simplicity while achieving comprehensive directional coverage.
Solution Approach 2:
The patent creates a universal brake indication system that serves multiple functions: communicating braking status to vehicles behind (original function) and to pedestrians/vehicles in front (new function). This multi-functionality is achieved through separate light assemblies that can be activated by the same braking signal, reducing overall system complexity despite expanded functionality.

AI summary
A visual deceleration indicator signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car or otherwise, are activated when the vehicle decelerates. An accelerometer or other sensory device detects deceleration and sends a signal to illuminate the LEDs, thereby letting others know the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car. The indicator might be one color to indicate braking and another color to indicate it is on, but not braking.
