Vehicle Lamp Merging Turn and Reverse Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rear combination lamps on vehicles are limited in design and visibility, as they require separate turn and reverse lamps, which can complicate the design and reduce visibility for drivers of other vehicles or pedestrians, especially in dark or night conditions.
Innovation Solution
A vehicle lamp system that incorporates a multi-lamp configuration, where a single multi-lamp can function as both a turn lamp and a reverse lamp by selectively radiating different colors of light based on driving conditions, controlled by a controller that responds to turn and reverse signals, eliminating the need for separate lamps and enhancing visibility and design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate turn lamp and reverse lamp are used, then each lamp can perform its specific function, but the design becomes complicated and visibility is reduced
Solution Approach 1:
The patent combines the turn lamp and reverse lamp into a single integrated lamp unit. The lamp housing contains both a turn signal light source and a reverse light source, with corresponding reflectors for each function. A control unit selectively activates the appropriate light source based on driving conditions, allowing one lamp structure to perform multiple functions that previously required separate lamps.
Solution Approach 2:
The integrated lamp unit is designed to perform multiple functions: it can operate as a turn signal lamp, a reverse lamp, or both simultaneously. The single lamp housing accommodates different light sources (turn signal light source and reverse light source) that can be independently controlled to serve different purposes based on the vehicle's operating state.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution improves visibility for drivers and pedestrians by extending the area of the turn lamp when the vehicle is moving forward, while saving costs by eliminating the need for a separate reverse lamp, and enhances the design flexibility of the rear combination lamp.
Implementation Method 1
a reflector for reflecting the light radiated from the reverse light source and the turn light source

AI summary
A vehicle having a lamp includes a multi lamp disposed to radiate a first color light for backward movement or a second color light for a turn movement of a vehicle. A turn lamp is disposed near the multi lamp portion to selectively radiate a second color light for a turning movement. A controller controls the operation of the multi lamp and the turn lamp depending on a turn signal or a reverse signal.
