Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional engine brake installations fail to illuminate standard brake lights when the engine brake is activated, which can lead to a lack of visual warning for trailing motorists about impending speed reduction.
Innovation Solution
A brake light control module with a thyristor-based control circuit that connects the vehicle's electrical system to the brake light service line upon engine brake activation, using a trigger lead to send a gate signal to the thyristor, ensuring the brake lights are illuminated during engine braking, and includes a delay circuit to prevent false activation during gear shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional engine brake installation is used, then the engine brake system can slow the vehicle, but the standard brake lights are not illuminated to warn trailing motorists
Solution Approach 1:
The patent combines the engine brake activation signal with the brake light activation circuit. The control module monitors the engine brake activation line and automatically triggers the brake lights when the engine brake is engaged, merging two previously separate functions into a unified safety system.
Solution Approach 2:
The control module acts as an intermediary device that receives the engine brake activation signal and translates it into a brake light activation signal. This intermediary component bridges the gap between the engine brake system and the brake light system, ensuring proper signal transmission and timing.
2Reliability
If brake lights are activated during gear shifts, then false warnings may be given to trailing motorists, but without activation the safety warning is lost
Solution Approach 1:
The control module performs preliminary monitoring of gear shift conditions before activating the brake lights. By detecting gear shift events in advance and blocking the brake light activation signal during these periods, the system prevents false warnings while maintaining safety functionality during actual engine brake application.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor vehicle operating conditions, including gear shift status and engine brake activation state. This feedback allows the control module to intelligently determine when brake light activation is appropriate and when it should be suppressed to avoid false warnings.

AI summary
A brake light control module for activating brake lights of a vehicle in response to activation of an engine brake of said vehicle. A control circuit of the module features a thyristor, a power lead and service lead for connection to the vehicle's electrical system and brake light service line across the thyristor, and a trigger lead for connection between the thyristor's gate terminal and an engine brake activation line of the vehicle to switch the thyristor to its conductive state when the engine brake activation line is energized. A delay circuit is installed in the power lead to prevent energization of the service lead in the event of a momentary gate signal indicative of an engine brake assisted gear shift. An operational indicator mounted within the housing is activated when the engine brake activation line is energized, thus confirming proper installation of the module.
