Progressive Brake Light Layout for Braking Intensity Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle brake lights do not effectively convey the intensity of braking, limiting the ability of following drivers to gauge the braking intensity of a preceding vehicle, which can lead to rear-end collisions.
Innovation Solution
A laterally elongated brake light that extends across the rear end of a vehicle, progressively illuminated from the center to the ends based on the engagement of the braking system, enhancing visibility of braking intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional brake light is used, then the structure is simple, but the braking intensity information is not effectively conveyed to following drivers
Solution Approach 1:
The brake light assembly is segmented into multiple independently controllable light emitting elements arranged in a gradient pattern across the rear surface. These segments can be illuminated at different intensities and patterns to encode braking intensity information, transforming a single-function light into a multi-level communication device that conveys progressive braking information without requiring complex mechanical components
Solution Approach 2:
The patent employs color or intensity variations in the light emission to differentiate braking intensity levels. By modulating the brightness, color temperature, or illumination pattern of the segmented light elements, the system communicates varying degrees of braking force to following drivers, using optical property changes rather than mechanical complexity to convey critical safety information
2Illumination intensity
If a brake light extends across the full width of the rear end, then the visibility and perception ability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
Rather than manufacturing a single large complex assembly, the brake light is divided into multiple standardized light emitting segments or modules that can be independently manufactured and then assembled in a specific gradient pattern. This modular approach achieves full-width coverage and enhanced visibility while simplifying the manufacturing process for each individual component and allowing for easier quality control and replacement
Solution Approach 2:
The patent integrates multiple light emitting elements, control circuits, and structural components into a unified brake light assembly that functions as a single communication device. By merging these components during the assembly process rather than requiring them to be manufactured as one complex piece, the system achieves full-width illumination coverage while maintaining ease of manufacture through modular integration techniques

AI summary
A vehicle brake light device includes a brake light that is mounted to a rear end of a vehicle. The brake light is turned on when a braking system of the vehicle is engaged thereby facilitating a driver of a following vehicle to be alerted that the vehicle is braking. Additionally, the brake light is progressively illuminated along a length of the brake light in accordance with a degree to which the braking system is being engaged thereby facilitating the driver of the following vehicle to be alerted to the degree to which the vehicle is braking such that the driver of the following vehicle can avoid a rear end collision with the vehicle. Furthermore, the brake light is laterally elongated to extend across a majority of a width of the rear end of the vehicle to enhance the driver of the following vehicle's ability to perceive the brake light.
