Vehicle Road Projection Through Integrated Headlight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projection technologies for vehicles do not effectively display necessary information based on the vehicle's traveling state.
Innovation Solution
An image projection apparatus that projects information onto a road surface or vehicle surfaces using an acquisition unit to gather vehicle data and an image projection unit to display this information based on acquired data, including speed, steering angle, and navigation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional image projection technologies are used for vehicles, then the apparatus can project images onto road surfaces, but the projected information does not effectively display necessary information based on the vehicle's traveling state
Solution Approach 1:
The patent merges the image projection apparatus with the vehicle's existing headlight assembly, integrating the projector, light source, and control systems into a unified structure. This combination allows the system to project contextualized information (speed, steering angle, navigation data) onto the road surface without requiring entirely separate systems, thereby improving information display effectiveness while managing device complexity through integrated design
Solution Approach 2:
The headlight assembly is designed to serve multiple functions: traditional illumination for nighttime driving and image projection for information display. By making the headlight assembly universal, the system can project various types of information (speed, steering angle, navigation routes, warnings) using the same hardware platform, improving information display effectiveness without proportionally increasing device complexity
2Reliability
If the projector is incorporated at the front of the headlight, then the system can project images onto the road, but the headlight cannot directly irradiate light flux onto the outside of the vehicle
Solution Approach 1:
The headlight assembly is segmented into distinct functional zones: one region dedicated to the projector for image projection and another region for the traditional light source for direct illumination. This segmentation allows both functions to operate simultaneously without interfering with each other, ensuring that the light source can directly irradiate light flux onto the outside of the vehicle while the projector provides reliable image projection onto the road surface
Solution Approach 2:
The patent introduces a reflective structure or optical element as an intermediary between the light source and the projection path. This intermediary component allows the light flux from the headlight to be directed appropriately, enabling both the projector to incorporate images at the front and the light source to efficiently irradiate the outside of the vehicle by mediating the light paths to prevent interference between the two functions

Data Source
AI summary
Based on information about a vehicle, the information can be projected and displayed onto a road surface or the like. An image projection apparatus, which projects an image, includes an acquisition unit that acquires the information about the vehicle, and an image projection unit that projects the image based on the information acquired by the acquisition unit.
