Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projection apparatuses for vehicles fail to effectively display various types of information necessary for vehicle travel, such as traveling state and navigation, on road surfaces.
Innovation Solution
An image projection apparatus that includes an acquisition unit to gather information and an image projection unit to project images based on vehicle-related data, utilizing a light control ECU to control the projection of images onto road surfaces, incorporating sensors and communication units for data input, and using projectors to display messages, navigation, and safety information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional image projection apparatuses are used for vehicles, then basic projection function is achieved, but effective display of various types of information necessary for vehicle travel is not realized
Solution Approach 1:
The image projection apparatus is designed to perform multiple functions beyond basic projection, including displaying navigation information, traveling state data, safety warnings, and communication messages on the road surface, making it a multi-functional information display system that adapts to various vehicle travel scenarios
Solution Approach 2:
The system uses the road surface as an intermediary medium to convey vehicle information to other road users. By projecting images onto the road surface between the vehicle and other drivers/pedestrians, it creates an effective communication channel that enhances situational awareness without requiring direct line-of-sight communication
2Adaptability or versatility
If simple projection without integrated sensors and communication units is used, then device complexity is reduced, but effective communication with other drivers and pedestrians is not achieved
Solution Approach 1:
The patent combines multiple previously separate systems into a single integrated image projection apparatus, merging sensor data acquisition, communication unit processing, and image projection functions into one unified system that displays all information types on the road surface through coordinated operation
Solution Approach 2:
The system divides information display into multiple functional segments: navigation information display, traveling state monitoring, safety warning projection, and communication message transmission. Each segment operates independently but contributes to the overall enhanced communication capability with other road users
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
Enables the projection and display of diverse information on road surfaces, enhancing vehicle safety and navigation through integrated image projection systems that utilize vehicle data for effective communication with other drivers and pedestrians.
Implementation Method 1
a light flux containing image information is projected onto a road surface or the like
Data Source
AI summary
Information related to a vehicle can be displayed by projecting an image based on the information on a road surface or the like. An image projection apparatus that projects an image includes: an acquisition unit that acquires information to be displayed; and an image projection unit that projects the image based on the information to be displayed acquired by the acquisition unit.
