Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems in vehicles are dedicated to specific components, increasing complexity and cost by not being shared between vehicle subsystems, limiting their versatility and efficiency in illuminating multiple areas.
Innovation Solution
A lighting system integrated into a vehicle's display panel with a light source and light guide that selectively illuminates both the display panel and adjacent accessories, using apertures and a color filter to provide uniform and customizable lighting, and a control system to manage illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems are dedicated to specific components, then each component receives adequate illumination, but the overall system complexity and cost increase
Solution Approach 1:
The patent implements a universal lighting system where a single light source within the display panel serves multiple functions: illuminating the display panel itself and illuminating adjacent vehicle accessories through apertures. This multi-functional approach eliminates the need for separate dedicated lighting systems for each component, thereby reducing overall system complexity while maintaining adequate illumination for all areas.
Solution Approach 2:
The patent merges the lighting function for the display panel and the lighting function for adjacent accessories into a single integrated system. The light source, control circuitry, and power supply are combined in one unit, replacing multiple separate lighting systems and reducing the total number of components required in the vehicle.
2Illumination intensity
If conventional lighting systems are dedicated to specific components, then each component has specialized lighting, but the cost of the vehicle increases
Solution Approach 1:
By designing the display panel's lighting system to serve multiple purposes - illuminating both the display and adjacent accessories - the patent reduces the total number of light sources, control circuits, and power supplies needed. This universal approach lowers material costs, assembly costs, and maintenance costs compared to implementing separate dedicated lighting systems for each vehicle component.
3Device complexity
If a unified lighting system is implemented, then complexity and cost are reduced, but selective illumination of different areas becomes challenging
Solution Approach 1:
The patent segments the illumination areas by incorporating apertures at specific locations on the display panel - some facing the display and others facing adjacent accessories. The control system can selectively activate different aperture groups to illuminate different areas, providing zone-based selective illumination while maintaining a single unified light source and control architecture.
Solution Approach 2:
The patent implements dynamic control of the lighting system through a control circuit that can independently regulate the intensity and activation of different aperture groups. This allows the system to adaptively illuminate different areas based on operational requirements, providing versatile selective illumination capability while maintaining system simplicity through a unified control architecture.
