Segmented Brake Light Layout for Braking Intensity Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile taillights do not provide clear information about the braking intensity of the leading vehicle, leading to potential collision risks and inefficient driving due to uncertainty in following distance and braking force.
Innovation Solution
A separate brake light is added to display the braking intensity of the leading vehicle, using a triangle-shaped brake light with eight rows of circular holes, each row illuminating differently based on the braking force, allowing the following vehicle to adjust its braking accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate brake light is added to display braking intensity, then information clarity about braking force is improved, but device complexity increases
Solution Approach 1:
The brake light system is segmented into multiple independent light-emitting units arranged in vertical rows, where each row or group of rows can be independently controlled to display different braking intensity levels. This segmentation allows the system to convey multiple levels of braking information using a modular structure.
Solution Approach 2:
The patent transitions from traditional horizontal or single-point brake light arrangements to a vertical multi-row configuration. By utilizing the vertical dimension with multiple rows of light-emitting units, the system can display graduated braking intensity levels (e.g., different numbers of illuminated rows corresponding to different braking forces) without significantly increasing horizontal space occupation.
2Measurement precision
If multiple rows of lights are used to indicate different braking levels, then braking intensity display capability is improved, but manufacturing complexity increases
Solution Approach 1:
The light-emitting units are segmented into distinct rows that can be independently controlled, with each row representing a specific braking intensity threshold. This segmentation simplifies the control logic and manufacturing process compared to a fully continuous variable system, as each row can be addressed independently to indicate different braking levels.
Solution Approach 2:
Different rows of light-emitting units are assigned different functions corresponding to different braking intensity ranges. The local quality of each row (its illumination state) provides specific information about the current braking level, allowing precise braking force indication through localized control of individual rows rather than requiring uniform adjustment across the entire light assembly.

AI summary
Existing automobile taillights integrate turn signals, running lights, and brake lights. This invention separates the brake light therefrom and adds a separate brake light. Viewed from the rear of the automobile, one brake light device is added on each side between the license plate and the existing taillight, one on the left and one on the right. This brake light is a triangle with a warning function. Eight rows of circular hole lights are uniformly distributed within the triangle, with every two rows forming one group, totaling four groups. Depending on the different braking force, this brake light will display different illumination levels from bottom to top. All four groups being fully illuminated corresponds to the heaviest brake pedal depression level. From heavy to light, the next level is the lower three groups of lights illuminating, followed by the lower two groups illuminating, and sequentially the bottommost one group illuminating. In this way, the following vehicle can perform reasonable braking on its own vehicle according to the illumination level of the leading vehicle's brake light, thereby avoiding excessive or insufficient braking operations, reducing safety accidents, and improving driving efficiency.
