Front Braking Light Wiring Circuit Topology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle braking light systems primarily focus on rear lights, failing to effectively warn drivers and pedestrians in front of or beside a braking vehicle, especially in complex traffic scenarios, and often strain the electrical circuit, leading to reliability and failure issues.
Innovation Solution
The implementation of a front braking light system where a red rear stop lamp is connected in series with the brake switch and a green front stop lamp is connected in parallel via an auxiliary control unit, independent of the main control unit, reducing current load and ensuring separate operation from other vehicle lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If front stop lamps are connected in parallel to rear stop lamps via a common electrical circuit, then the wiring complexity is reduced, but the electrical circuit experiences significant current load strain causing reliability issues and failure rates
Solution Approach 1:
The patent divides the electrical circuit into two independent segments: a first electrical circuit for rear stop lamps and a second electrical circuit for front stop lamps. Each circuit has its own power supply connection, control unit, and wiring path, eliminating the current load strain that occurs when all lamps share a common circuit while maintaining manageable wiring complexity through modular design.
2Adaptability or versatility
If identical red colour is used for both front and rear stop lamps, then the signalling is consistent, but the front stop lamps may be confused with similarly coloured side marker lights and turn signals
Solution Approach 1:
The patent applies different colour qualities to front and rear stop lamps: rear stop lamps use the conventional red colour, while front stop lamps use a distinct green colour. This local differentiation ensures that each light serves its specific function with unambiguous visual identification, preventing confusion with other green front lights while maintaining consistent braking signal functionality across the vehicle.
3Reliability
If separate electrical circuits are used for front and rear stop lamps, then the reliability and failure rate are improved, but the device complexity and acquisition cost increase
Solution Approach 1:
The patent employs universal components and standardized wiring configurations for both the first electrical circuit (rear stop lamps) and the second electrical circuit (front stop lamps). Both circuits use similar control units, power supply connections, and wiring topologies, allowing the system to achieve improved reliability through circuit separation while minimizing complexity increases through component reuse and standardized designs.

AI summary
The wiring of front braking lights for vehicles refers to a front light signalling device for transport vehicles in road traffic. The device consists of a power supply to which at least one red rear stop lamp is electrically connected via a brake switch arranged in series and actuated by brake pedal or a pull rod from the vehicle and via the vehicle's main control unit. Downward of braking switch (2), the input of at least one green front stop lamp (6) is electrically connected in parallel to the red rear stop lamp (4) via auxiliary control unit (5), the input of which is connected upstream or downstream of the vehicle's main control unit (3), with the output of the at least one green front stop lamp (6) connected to the power negative pole of the vehicle power supply (1), and the vehicle's main control unit (3) and auxiliary control unit (5) electrically connected to the vehicle power supply (1)
