Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting systems pose safety risks due to blind spots from rearview mirrors and glare from high beams, which can lead to driver distraction and increased accident likelihood.
Innovation Solution
A vehicle-mounted system featuring a directional and intensity-adjustable lamp system that includes a direction changing unit and a light intensity adjusting unit, integrated with image acquisition and processing to optimize light distribution and reduce glare, along with a dimming system and display system to enhance driver visibility and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high beam is used to improve road visibility, then illumination intensity is improved, but glare to other drivers increases causing safety hazards
Solution Approach 1:
The patent divides the vehicle lamp into multiple independent light emitting units arranged in different regions (left, middle, right). Each unit can be independently controlled to emit light in specific directions. The left and right region units illuminate road edges while the middle region unit illuminates the central road, allowing localized illumination without creating glare for oncoming drivers.
Solution Approach 2:
The vehicle lamp system is segmented into multiple light emitting units with different functions. The direction changing unit is also segmented into multiple units corresponding to different light emitting regions. This segmentation allows independent control of each unit's light direction and intensity, enabling the system to illuminate specific areas without causing glare to other drivers.
2Area of stationary object
If rearview mirrors are used to observe surrounding environment, then visual coverage is improved, but visual blind regions are created between mirror fields of view
Solution Approach 1:
The patent introduces a display system as an intermediary to complement the rearview mirror system. Image acquiring devices capture views from areas not visible in the mirrors, and the display system presents these images to the driver. This intermediary system fills the visual blind regions between mirror fields of view without requiring the driver to directly view blind spots.
3Object-affected harmful factors
If frequent switching between high beam and low beam is required to avoid glare, then glare interference is reduced, but driver distraction increases
Solution Approach 1:
The patent implements an automatic control system that monitors the presence of oncoming vehicles and automatically adjusts the beam pattern. The control unit receives signals from image acquiring devices to detect oncoming vehicles and automatically switches between different light emitting patterns without driver intervention. This eliminates the need for manual switching and reduces driver distraction while maintaining glare control.
4Illumination intensity
If conventional vehicle lamps are used to illuminate road ahead, then basic illumination is provided, but blind spots remain and glare cannot be effectively controlled
Solution Approach 1:
The patent implements local quality by assigning different light emitting units to different spatial zones. Left region units illuminate the left road edge, middle region units illuminate the central road, and right region units illuminate the right road edge. This localized illumination approach ensures complete coverage of the road ahead without creating blind spots, while each unit's directed beam prevents glare to oncoming drivers.
