Dashboard Remote Image Display Layout for Clear Driver Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle dashboard display systems face issues of space clutter, high production costs, and readability challenges, particularly with traditional digital displays and Head-Up Displays, which can obstruct the driver's view and are bulky.
Innovation Solution
A display system comprising a source screen and a translucent plate in the dashboard cavity, forming a remote image offset from the screen, with adjustable angle and illumination options, including natural light and adjustable light sources, to create an open and bright perception of information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional digital display with protective glass is used, then the display function is provided, but the dashboard space is cluttered and production cost increases
Solution Approach 1:
The patent uses a light guide plate to create a virtual image copy of the display content, allowing the actual screen to be positioned in the upper cavity while the image appears on the dashboard surface. This copying approach eliminates the need for physical display components on the dashboard, freeing up space while maintaining the display function.
Solution Approach 2:
The display system transitions from a two-dimensional dashboard surface to a three-dimensional configuration by placing the source screen in the upper cavity and using optical paths to project the image to the dashboard level. This dimensional change allows space optimization while preserving display functionality.
2Area of stationary object
If a Head-Up Display is used to free up dashboard space, then dashboard space is freed, but production cost significantly increases due to complex technical infrastructure
Solution Approach 1:
The patent creates a virtual image copy through the light guide plate, which is a simpler and more cost-effective approach compared to complex Head-Up Display systems. This copying mechanism achieves the space-saving goal without requiring sophisticated optical infrastructure.
Solution Approach 2:
The light guide plate serves as a relatively simple and cost-effective optical element compared to complex HUD systems. It provides the necessary image projection function at a lower production cost, making it an economical solution for freeing dashboard space.
3Area of stationary object
If a Head-Up Display is used to free up dashboard space, then dashboard space is freed, but driver vision is hindered when focusing on the screen
Solution Approach 1:
The virtual image is projected to appear on the dashboard surface rather than floating in the driver's line of sight. This positioning of the image copy ensures that drivers can view the display without it obstructing their vision of the road, while still achieving dashboard space optimization.
4Area of stationary object
If a translucent plate is used to form a remote image, then dashboard space is freed and design is refined, but additional optical components are required
Solution Approach 1:
The light guide plate performs multiple functions: it guides light from the source screen, creates the virtual image, and serves as a structural component within the dashboard cavity. This multi-functionality reduces the need for separate optical components, balancing the complexity increase with functional consolidation.
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
Frees up dashboard space, reduces production costs, and enhances readability by projecting a virtual image that appears empty, providing a refined design and adjustable illumination effects.
Implementation Method 1
a translucent plate installed inside the cavity adapted to form an image offset from the source screen... the translucent plate having an upper edge and a lower edge, and defines a free space with the bottom of the dashboard, said offset image being formed in the free space defined by the plate and on the side opposite the source screen with respect to the translucent plate
