Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle clusters are limited in displaying information, as they can only express 2D information, leading to limited information output, potential driver dizziness from stereoscopic images, and visibility issues due to ambient light, with existing solutions like head-up displays having structural limitations and eye fatigue problems.
Innovation Solution
A vehicle cluster incorporating a spatial image panel with a first and second lens array and a refractive medium, allowing for adjustable 3D image output in a predetermined space, reducing eye strain, and an air touch sensor for intuitive control, enabling clear stereoscopic images with improved visibility and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If stereoscopic images are output through a vehicle cluster, then 3D information is provided to the driver, but the driver may feel dizzy due to afterimages or vibrations
Solution Approach 1:
A spatial image panel is introduced as an intermediary component between the display and the driver. This panel includes a first lens array and a second lens array that work together to convert 2D display images into 3D spatial images, providing depth information without directly exposing the driver to harmful stereoscopic effects
Solution Approach 2:
The patent transitions from 2D flat display to 3D spatial imaging by adding a depth dimension. The spatial image panel creates virtual images at different depths in front of the display, allowing drivers to perceive 3D information while maintaining comfortable viewing conditions
2Device complexity
If information is displayed on a predetermined plane in a cluster, then the cluster structure is simple, but the amount of information that can be displayed is limited
Solution Approach 1:
The patent adds a depth dimension to the traditional 2D cluster display by introducing a spatial image panel with lens arrays. This creates a 3D display space in front of the cluster, significantly increasing information capacity while maintaining a relatively simple overall structure
Solution Approach 2:
The spatial image panel is positioned in front of the display, with the first and second lens arrays nested within the panel structure. This nested arrangement allows the 3D display functionality to be integrated into the existing cluster without requiring separate complex systems
3Ease of operation
If head-up display (HUD) is used to display information on the windshield, then the user can identify vehicle driving information without lowering the head, but visibility changes heavily depending on the peripheral brightness
Solution Approach 1:
The spatial image panel creates virtual 3D images that appear to float in front of the display, copying the essential information in a enhanced format. This allows drivers to maintain their gaze on the cluster while perceiving 3D spatial information, improving attention continuity
4Measurement precision
If the user moves the gaze to a designated cluster screen to identify driving information, then the information can be displayed clearly, but the driver's gaze is distracted
Solution Approach 1:
By creating 3D virtual images in space rather than on a flat screen, the patent allows drivers to perceive information with depth cues while maintaining a more natural viewing position, reducing the need for excessive gaze movement
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 enables clear, adjustable, and high-visibility stereoscopic images without causing driver dizziness, while allowing for intuitive control of vehicle functions through touch inputs, enhancing space efficiency and reducing eye fatigue.
Implementation Method 1
The spatial image panel includes a first lens array, a second lens array, and a refractive medium. The first lens array is disposed adjacent to the display and includes a plurality of first lenses arranged on the same plane. The second lens array is disposed in parallel with the first array so that the first lenses and second lenses overlap each other. The refractive medium is disposed between the first lens array and the second lens array.
