Solution Overview
Problem
Conventional image projection apparatuses for vehicles are inadequate in displaying various types of information necessary for vehicle travel, such as traveling state and navigation, effectively on road surfaces or vehicle surfaces.
Innovation Solution
An image projection apparatus that acquires and projects information onto road surfaces or vehicle surfaces using a configuration including an acquisition unit and an image projection unit, integrated with a light control ECU that utilizes various sensors and a projector to display images based on vehicle information, such as traveling speed, navigation data, and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional image projection apparatuses are used in vehicles, then basic projection function is achieved, but the ability to display various types of information necessary for vehicle travel is insufficient
Solution Approach 1:
The image projection apparatus is designed to perform multiple functions: projecting navigation routes, displaying vehicle traveling state information, and providing visual warnings to other road users. By integrating these diverse information display capabilities into a single projection system, the apparatus achieves multi-functionality without proportionally increasing complexity
Solution Approach 2:
The patent combines the navigation system, vehicle state sensing systems, and image projection system into an integrated apparatus. The control unit synthesizes data from multiple sources (navigation data, traveling state data) and coordinates their display through a unified projection interface, merging multiple subsystems into one cohesive system
2Loss of information
If multiple types of information are projected on road surfaces, then information effectiveness for vehicle travel is improved, but image recognition accuracy may be compromised
Solution Approach 1:
The projection apparatus divides the road surface into multiple distinct projection regions, each dedicated to displaying specific types of information (navigation route, traveling state, warnings). This segmentation prevents information overlap and ensures each information type maintains its visual clarity and recognizability
Solution Approach 2:
Different regions of the projection system are optimized for different information types, with appropriate brightness, color, and projection angles tailored to each information category. This local optimization ensures that each information element achieves maximum recognizability while maintaining overall information completeness
