Solution Overview
Problem
Existing vehicle interior lighting systems emit stray light that can distract drivers, especially during night or tunnel driving, impairing safety.
Innovation Solution
A lighting system with a light strip or light guide integrated into the instrument panel, designed to highlight contours and create a situational lighting atmosphere, reducing stray light and enhancing driver orientation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting system illuminates a large area in the vehicle interior, then the contours of interior components can be highlighted and orientation improved, but stray light is generated that disturbs the driver and reduces driving safety
Solution Approach 1:
The lighting system transitions from uniform area illumination to localized contour illumination. Light strips are positioned along the contours of the instrument panel, door panels, and center console to highlight edges and shapes without illuminating the entire interior space, thereby maintaining orientation benefits while minimizing driver distraction
Solution Approach 2:
The lighting system is divided into multiple independent light strips positioned at different locations (instrument panel, door panels, center console) rather than a single large illumination source. This segmentation allows selective illumination of specific contours and regions, reducing overall stray light while maintaining effective contour highlighting
2Ease of operation
If the lighting system highlights contours of interior components, then driver orientation and accessibility are improved, but the complexity of the lighting device increases
Solution Approach 1:
The lighting system uses thin, flexible light strips that can be easily conformed to and integrated into the contours of various interior components. These flexible strips simplify installation and integration compared to rigid lighting structures, reducing overall system complexity while achieving effective contour highlighting
Solution Approach 2:
The lighting elements are integrated into existing interior components such as the instrument panel, door panels, and center console rather than being separate add-on systems. This merging approach reduces overall system complexity by utilizing existing structural elements as mounting surfaces and integrating lighting functions into already-present components
