Vehicle Display Arrangement Using Image Splitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display arrangements for motor vehicles are costly due to the high expense of imagers, making it impractical to install additional displays for presenting information to occupants.
Innovation Solution
A projection apparatus with an image splitter separates the image into two sections, allowing for the projection of different information onto separate display areas using a single imager, with the ability to adjust brightness and orientation for optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imagers are installed to display information to multiple occupants, then information presentation capability is improved, but manufacturing costs increase
Solution Approach 1:
The single image generated by one imager is segmented into multiple image sections using an image splitter, which divides the image into separate sections that can be projected to different occupants or display areas, enabling one imager to serve multiple functions
Solution Approach 2:
A single imager is designed to perform multiple functions by projecting different image sections to different occupants simultaneously, making the imager universal for serving driver, passenger, and multiple display areas without requiring separate imagers for each function
2Ease of manufacture
If a single imager is used for multiple display areas, then manufacturing costs are reduced, but image content differentiation capability is limited
Solution Approach 1:
The image from a single imager is divided into multiple distinct image sections by the image splitter, allowing different content to be presented in each section to different occupants or display areas, thus achieving content differentiation with one imager
Solution Approach 2:
An image splitter is introduced as an intermediary device between the single imager and multiple display areas, enabling the imager to produce differentiated content for each occupant by separating the image into distinct sections with different information
3Ease of operation
If display areas are positioned at different locations, then information accessibility is improved, but optical path complexity increases
Solution Approach 1:
The image splitter divides the image not only spatially but also directs different sections along different optical paths to different display areas, adding dimensional separation that simplifies the overall optical configuration while maintaining accessibility
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 solution reduces manufacturing costs by utilizing a single imager to present multiple types of information to vehicle occupants, improving comprehension through distinct and adjustable image presentation.
Implementation Method 1
the image splitter may be constructed as a concave reflector, in particular a concave mirror
