Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separate provision of LiDAR and display devices on vehicles or mobile robots leads to interference with sensing areas, increased cost, and distortion of images due to water droplets, particularly in limited spaces.
Innovation Solution
An integrated image display device with a rotatable housing containing a scanning unit and image display unit, where the scanning unit and image display unit are spaced to avoid overlap, and a control unit manages rotation speeds and light source activation to integrate LiDAR sensing and image generation without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LiDAR and display are provided separately on the top portion of mobility, then both functions can be implemented, but the display interferes with the sensing region of LiDAR, reducing the sensing area
Solution Approach 1:
The patent merges the LiDAR sensing function and display function into a single integrated device. The housing contains both the scanning unit (LiDAR) and image display unit, allowing both functions to be performed without requiring separate installations that would interfere with each other's operational space
Solution Approach 2:
The patent arranges the scanning unit and image display unit in different spatial dimensions within the housing. The scanning unit is positioned to scan in specific directions while the display unit is arranged on the housing surface, utilizing three-dimensional space arrangement to prevent overlap between sensing and display regions
2Adaptability or versatility
If LiDAR and display are provided separately, then both functions can be implemented, but it is difficult to secure space for installing both in limited space on top portion of mobility
Solution Approach 1:
The patent combines LiDAR and display into a single integrated housing unit, reducing the total volume required for installation. Instead of requiring separate mounting spaces for two independent devices, the integrated design allows both functions to share a common housing structure
Solution Approach 2:
The patent nests the scanning unit and image display unit within a single housing structure. The scanning unit is positioned inside the housing while the display unit is arranged on the housing surface, creating a nested configuration that maximizes space utilization
3Adaptability or versatility
If LiDAR and display are provided separately, then both functions can be implemented, but cost is increased
Solution Approach 1:
The patent merges two separate devices (LiDAR and display) into a single integrated unit, reducing the total component count and assembly requirements. This integration reduces manufacturing complexity and material costs compared to providing separate LiDAR and display devices
Solution Approach 2:
The housing serves multiple functions simultaneously: it protects the scanning unit, provides the scanning mechanism, and displays images. This multi-functionality reduces the need for separate components and structures, thereby reducing overall manufacturing cost
4Ease of operation
If display is configured in a way of simply projecting an image, then image can be displayed, but image is distorted due to formation of water droplets
Solution Approach 1:
The patent rotates the housing at a preset speed when generating an image, creating a dynamic display mechanism. This rotation prevents water droplets from forming on the display surface by continuously moving it, thereby maintaining image quality without compromising display simplicity
Solution Approach 2:
The patent uses periodic rotation of the housing at preset speeds to prevent water droplet formation. The periodic motion creates conditions unfavorable for condensation while maintaining the simplicity of the display projection method

Implementation Method 1
utilizes the time, intensity and the like of the reflected light which is reflected from a surrounding object or terrain
Implementation Method 2
a laser radar device such as a light detection and ranging (LiDAR) is used to detect a surrounding terrain or object
Implementation Method 3
generating of an image on the side surface of the housing by afterimage effect caused by the rotation of the housing

AI summary
A display image device includes a sensor in which when a surrounding object is detected through a scanning unit, an image display unit operates together with and the image for message delivery to an outside is implemented, so that Light Detection and Ranging (LiDAR) sensing function and image implementation may be integrated, a package may be reduced and a LiDAR sensing area may be secured.
