Vehicle Additional Lamp Mode Control via Braking Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aftermarket vehicle lamps cannot be conveniently switched between different operational modes using the original vehicle controls, limiting their functionality and user convenience.
Innovation Solution
A method that uses continuous and intermittent signals from the vehicle to control and switch the operational modes of additional lamps, allowing them to generate flickering or non-flickering light based on braking operations, without requiring additional switches or modifications, by utilizing existing braking and position lamp signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aftermarket vehicle lamps are used to provide multiple operational modes, then the alarming effect and functionality are enhanced, but the ease of operation deteriorates because they cannot be switched using original vehicle controls
Solution Approach 1:
The additional lamp system automatically detects vehicle braking states and autonomously switches between flickering and non-flickering modes without requiring manual user input. The control unit monitors braking signals and position lamp signals to determine when mode switching is appropriate, making the system self-serve the user's needs.
Solution Approach 2:
The system changes the operational parameter of the additional lamp (flickering frequency and pattern) based on detected vehicle states. By monitoring braking duration and position lamp activation, the control unit dynamically adjusts the lamp's output characteristics to match appropriate operational modes.
2Ease of operation
If additional control devices are added to switch lamp modes, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the additional lamp's operational modes, monitors vehicle braking signals, detects position lamp states, and manages mode transitions. By making the control unit multi-functional, no additional dedicated switching devices are required.
Solution Approach 2:
The control unit acts as an intermediary that translates existing vehicle signals (braking signals and position lamp signals) into appropriate additional lamp operational modes. This mediator approach allows the system to use existing vehicle control infrastructure rather than adding new control devices.
3Reliability
If the additional lamp provides flickering mode for enhanced alarming effect, then the safety alert capability is improved, but the reliability may deteriorate due to potential misoperation
Solution Approach 1:
The control unit continuously monitors vehicle braking signals and position lamp signals to determine when to activate flickering mode. This feedback mechanism ensures the additional lamp only operates in flickering mode when the vehicle is actually braking, preventing misoperation and ensuring reliable safety alerts.
Solution Approach 2:
The system pre-sets the additional lamp to non-flickering mode as the default state. Flickering mode is only activated after specific conditions are met (vehicle braking detected), ensuring the lamp operates correctly by default and only enhances functionality when needed.

AI summary
A method for controlling and switching operational modes of an additional lamp for a vehicle includes confirming a pre-set operating mode of the additional lamp. The additional lamp is switched from the pre-set operating mode to another operating mode only when a continuous first signal and intermittent plural second signals come from the vehicle. When the brake is operating and the additional lamp is in a non-flickering mode, the additional lamp generates non-flickering light. When the brake is operating and the additional lamp is in the flickering mode, the additional lamp generates flickering light. The additional lamp is turned off when the braking operation stops. When the braking operation continues and the additional lamp is in the flickering mode, the additional lamp keeps outputting flickering light. When the braking operation continues and the additional lamp is in the non-flickering mode, the additional lamp keeps outputting non-flickering light.
