Panorama Projection Unit for Motor Vehicle Dashboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle dashboards with multiple display and projection units become cluttered and distracting due to the complexity of images and control elements, diverting the driver's attention from essential information.
Innovation Solution
A panorama projection unit featuring a three-dimensional panoramic screen with rear-side projectors that map images and control elements without distortion, shielding the projection beams from the driver and passenger, and utilizing a semi-transparent rear-side coating and anti-reflection coating to reduce reflections and enhance visibility, allowing for a unified and clear display of vehicle functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices and projection units are distributed throughout the vehicle interior, then comprehensive display of vehicle functions is achieved, but the dashboard becomes cluttered and distracting to the driver
Solution Approach 1:
The patent consolidates multiple distributed projection units into a single panorama projection unit that projects images onto a panoramic screen spanning the entire front area of the vehicle. This merging approach maintains comprehensive display coverage while simplifying the overall system structure and reducing dashboard clutter
Solution Approach 2:
The panoramic screen serves as a universal display surface that can present multiple vehicle functions, control elements, and information types simultaneously across its entire area. This multi-functional approach replaces the need for multiple specialized display devices while maintaining adaptability to various display needs
2Adaptability or versatility
If multiple display devices are provided in different positions, then comprehensive vehicle function control is enabled, but installation space requirements increase
Solution Approach 1:
The patent combines multiple display functions and control interfaces into a single panoramic display system, reducing the number of separate display devices and their associated installation spaces while maintaining comprehensive vehicle function control capability
3Device complexity
If a large panoramic screen covers the full width of the vehicle interior, then multiple separate indicating devices are no longer needed, but the screen size and material requirements increase
Solution Approach 1:
The panoramic screen is divided into multiple projection areas, each handled by separate projection units that can be independently controlled. This segmentation allows the large screen to be managed as multiple smaller functional zones, reducing the complexity of controlling a single large display while maintaining the space-saving benefit
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
The solution reduces the error rate of conventional systems, provides improved creative freedom in dashboard layout, and reduces manufacturing costs and weight by integrating multiple functions into a single panoramic screen, ensuring only necessary images and control elements are displayed, thus enhancing driver focus and safety.
Implementation Method 1
an anti-reflection coating on its front
Implementation Method 2
the panoramic screen to include a semi-transparent rear-side coating on its back

AI summary
A panorama projection unit is disclosed which concentrates the projected images in a front area of the motor vehicle and temporarily or locally shades the projection beams between projection units and the display surfaces. The panorama projection unit includes a three-dimensional panoramic screen, a plurality of projectors which project images onto a rear side of the panoramic screen, and a central control unit which controls the projectors in such a way that the projected images are mapped without distortion on the three-dimensional panoramic screen.
