Vehicular Light Source Housing for Automatic Driving Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving vehicle technologies impact vehicle design due to the need for multiple lamp units to alert drivers, leading to design inefficiencies and potential light mixture issues.
Innovation Solution
A vehicular apparatus with a housing that integrates first and second light sources emitting light in different wavelength ranges, specifically turquoise (490 nm-498 nm) and amber (577 nm-587 nm), to alert automatic driving, reducing the number of housings and preventing light mixture through strategic arrangement and reflecting structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate lamp units are provided to alert automatic driving, then the alerting function is achieved, but the impact on vehicle design increases and light mixture issues occur
Solution Approach 1:
The patent combines multiple light sources (first light source for alerting automatic driving and second light source for other functions) into a single housing. This merging approach maintains the alerting function while reducing the number of separate lamp units, thereby decreasing impact on vehicle design and preventing light mixture issues that would occur with multiple separate units positioned close to each other.
Solution Approach 2:
Within the single housing, the patent segments the light sources by providing specific structures (such as light shields or spatial separation) that prevent the light from the first light source from mixing with the light from the second light source. This segmentation of light paths maintains functional separation while achieving physical consolidation.
2Reliability
If multiple separate lamp units are provided to alert automatic driving, then the alerting function is achieved, but light mixture occurs between different light sources
Solution Approach 1:
By consolidating multiple light sources into one housing, the patent reduces the spatial proximity between different light sources compared to having multiple separate lamp units. This merging approach, combined with internal separation structures, prevents light mixture while maintaining the alerting function.
Solution Approach 2:
The patent introduces intermediary structures within the housing (such as light shields, reflectors, or spatial barriers) that act as mediators to prevent light from the first light source from mixing with light from the second light source. These intermediaries maintain functional separation without requiring completely separate housings.

Function Achieved in This Case
This solution minimizes the impact on vehicle design by consolidating light sources within a single housing and prevents light mixture, enhancing the alerting functionality while maintaining aesthetic and functional efficiency.
Implementation Method 1
first and second light sources that are provided in the housing to emit light having main wavelengths in mutually different wavelength ranges. The first light source emits light having a main wavelength in 490 nm-498 nm
