AR HUD Optical Head Separation for Vehicle Dashboard Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality head-up display systems for vehicles have large volumes of controller hosts, poor heat dissipation, complex imaging light paths, large space requirements, and poor imaging quality due to the internal arrangement of the image projection head and controller host.
Innovation Solution
The system rearranges the augmented reality image projection main optical head outside the dashboard and the controller host inside, with a light path allowing light to pass through the dashboard, reducing the volume of the controller host and simplifying the imaging path, and uses a reflective imaging plate, such as a front windshield or specular film, to enhance imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the augmented reality image projection main optical head is arranged inside the augmented reality head-up controller host, then the system structure is compact, but the controller host volume becomes large and heat dissipation becomes poor
Solution Approach 1:
The patent divides the system into two separate parts: the augmented reality image projection main optical head is arranged outside the dashboard while the controller host is arranged inside the dashboard. This segmentation allows the optical head to be separated from the controller host, reducing the controller host volume and improving heat dissipation conditions for the optical head.
Solution Approach 2:
The patent utilizes the spatial dimension by arranging components in different locations relative to the dashboard. The optical head is positioned outside the dashboard while the controller host is inside, creating a three-dimensional spatial distribution that resolves the volume-heat dissipation contradiction.
2Device complexity
If the augmented reality image projection main optical head is arranged inside the controller host, then the system is integrated, but the imaging light path becomes complex
Solution Approach 1:
The patent segments the imaging system by placing the optical head outside the dashboard and the controller host inside, which simplifies the internal light path structure within the controller host while maintaining system functionality through coordinated operation of the separated components.
3Area of stationary object
If the augmented reality image projection main optical head is arranged inside the controller host, then the system is compact, but the dashboard space requirements increase
Solution Approach 1:
The patent separates the optical head from the controller host and places the optical head outside the dashboard. This segmentation reduces the volume of the controller host that needs to be accommodated within the dashboard space, thereby freeing up dashboard area for other vehicle components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the volume of the controller host, improves heat dissipation, simplifies the light path, and enhances imaging quality, providing a more compact and effective augmented reality display for drivers.
Implementation Method 1
light emitted by the augmented reality image projection main optical head is capable of passing through the light path to reach the augmented reality head-up controller host
Implementation Method 2
continuing to pass, through light reflection in the augmented reality head-up controller host, out of the light path to reach the reflective imaging plate
Implementation Method 3
and then achieving augmented reality head-up imaging through reflection of the reflective imaging plate
