Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projection technologies for vehicles do not effectively display necessary information based on the vehicle's traveling state.
Innovation Solution
An image projection apparatus that projects information onto a road surface or vehicle surfaces using an acquisition unit to gather vehicle data and an image projection unit to display this information, incorporating components like a CPU, RAM, ROM, and various sensors to control the projection based on vehicle information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional image projection technologies are used for vehicles, then basic projection function is achieved, but the information displayed does not effectively reflect the vehicle's traveling state
Solution Approach 1:
The patent combines multiple functions into a single projection system: acquiring vehicle traveling state data, processing this information, and projecting it onto the road surface. The control unit integrates data from various sensors (accelerometer, gyroscope, GPS) and merges it with projection control to display comprehensive vehicle state information, thereby reducing information loss without proportionally increasing device complexity.
Solution Approach 2:
The projection apparatus is designed to perform multiple functions: it can display vehicle speed, direction, acceleration, and other traveling state parameters simultaneously. The system adapts to different projection surfaces (road, wall, vehicle body) and can adjust projection content based on vehicle state, making it a universal display solution that handles diverse information requirements.
2Loss of information
If simple projection without vehicle data integration is used, then device complexity is low, but the information displayed is not relevant to vehicle traveling state
Solution Approach 1:
The control unit serves as an intermediary between the vehicle's sensor systems and the projection apparatus. It receives raw data from sensors (accelerometer, gyroscope, GPS), processes and interprets this information, and translates it into visual projections. This intermediary layer enables effective information display without requiring direct complex integration between all sensors and the projection system.
3Adaptability or versatility
If dynamic projection based on vehicle state is implemented, then information relevance is improved, but the system requires more complex acquisition and control mechanisms
Solution Approach 1:
The projection system is designed to be dynamic, continuously adjusting the projected information based on real-time vehicle state data. The control unit monitors changing parameters (speed, direction, acceleration) and dynamically updates the projection content and position. This dynamic adaptation allows the system to remain relevant to vehicle state without requiring a completely reconfigurable system for each parameter change.

AI summary
Based on information about a vehicle, the information can be projected and displayed onto a road surface or the like. An image projection apparatus, which projects an image, includes an acquisition unit that acquires the information about the vehicle, and an image projection unit that projects the image based on the information acquired by the acquisition unit.
