Segmented Linear Lighting for Vehicle Navigation Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicles lack effective means to provide improved orientation to passengers during navigation guidance, as existing linear lighting devices primarily serve aesthetic purposes and do not convey directional information effectively.
Innovation Solution
A motor vehicle with a linear lighting device divided into segments, controlled by a device that determines direction information from navigation data and ego-positioning, to selectively activate and configure lighting segments for visualizing the destination direction, incorporating ambient brightness adjustment and passenger perspective consideration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If linear lighting devices are used for ambient illumination only, then aesthetic improvement is achieved, but directional information for navigation is not provided
Solution Approach 1:
The linear lighting device is designed to perform multiple functions: it provides ambient illumination for aesthetic purposes while simultaneously serving as a directional indicator for navigation guidance. The control device enables the lighting segments to visualize destination direction based on navigation data, transforming a single-function aesthetic component into a multi-functional system that combines illumination with information communication.
2Loss of information
If the lighting device is divided into multiple segments, then directional visualization capability is improved, but device complexity increases
Solution Approach 1:
The linear lighting device is divided into multiple independently controllable lighting segments along its extension. This segmentation enables selective activation of specific segments to indicate directional information towards the destination. The control device receives navigation data and activates appropriate segments to visualize the direction, allowing the system to communicate spatial information without requiring complex mechanical or electronic mechanisms beyond simple segment control.

AI summary
A motor vehicle, comprising at least one linear lighting device for directly or indirectly lighting a vehicle interior. The at least one lighting device extends, at least in some sections, horizontally along at least one component of the motor vehicle. The motor vehicle additionally comprises a position-sensing unit for sensing ego information describing a position and an orientation of the motor vehicle. The at least one lighting device is divided horizontally into a plurality of lighting segments, each having a fixed emission profile. The motor vehicle has a control device, configured to: determine a direction of the destination in relation to the motor vehicle; select a sub-group of the plurality of lighting segments comprising at least one lighting segment to be activated; and activate the at least one lighting segment belonging to the sub-group according to lighting brightness or lighting color of the at least one lighting segment.
