Integrated Vehicle Lighting Housing for Interior and Road Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost associated with requiring two separate vehicle lighting devices, one for interior illumination and another for exterior road-surface drawing, as existing solutions do not efficiently combine these functions in a single device.
Innovation Solution
A vehicle lighting device incorporating a housing with a first optical system for interior illumination and a second optical system for exterior information display, both utilizing light sources and lenses, allowing a single device to perform both functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate vehicle lighting devices are used (one for interior illumination and another for exterior road-surface drawing), then the illumination functions are reliable and effective, but the cost increases
Solution Approach 1:
The patent combines two separate lighting devices into a single integrated device. The housing contains both a first optical system for interior illumination and a second optical system for exterior road-surface drawing, allowing both functions to be performed by one device rather than requiring separate installations
Solution Approach 2:
The single lighting device is designed to perform multiple functions: the first optical system illuminates the vehicle interior while the second optical system draws colored images on the road surface. This multi-functional design eliminates the need for separate dedicated devices for each function
2Adaptability or versatility
If two separate vehicle lighting devices are installed, then each function is optimized independently, but the device complexity increases
Solution Approach 1:
The lighting device is segmented into distinct optical systems within a single housing. The first optical system with its light source and lens is separated from the second optical system, allowing each to be optimized for its specific function while being part of an integrated unit
