Color-Coded Road Navigation Using Transportation Guiding Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems often require drivers to frequently consult mobile devices or built-in navigation interfaces, which can be risky and inconvenient, especially in complex road networks, leading to safety and inconvenience issues.
Innovation Solution
A method and apparatus that utilize transportation guiding apparatuses integrated with road signs and traffic lines to provide accurate navigation information through color-coded instructions, allowing drivers to identify their route directly from real-world facilities without needing to match virtual navigation with real-world signage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers use mobile devices or built-in navigation interfaces to get navigation information, then navigation information can be provided to drivers, but driver safety deteriorates due to frequent device consultation while driving
Solution Approach 1:
The patent introduces transportation guiding apparatuses (road signs, traffic lines, projection devices) as intermediaries between the navigation system and the driver. These apparatuses display navigation information in the real world environment, allowing drivers to receive guidance without diverting attention from the road. The guiding apparatuses act as a mediator that translates digital navigation data into physical world visual cues.
Solution Approach 2:
The patent replaces the mechanical interaction of drivers manually checking mobile devices or screens with an automated optical display system. Projection devices and road signs automatically project navigation information onto the road surface or roadside structures, substituting the manual screen-checking action with passive visual reception in the driver's field of view.
2Loss of information
If traditional navigation interfaces are used, then navigation information can be displayed, but navigation accuracy deteriorates when matching virtual navigation with real-world transportation facilities
Solution Approach 1:
The patent employs color-coded navigation information displayed on transportation guiding apparatuses. Different colors indicate different route instructions (e.g., green for continue straight, yellow for prepare to turn, red for stop). This color-coding system enhances the precision of route identification by providing intuitive visual cues that directly correspond to required actions, eliminating the need for drivers to interpret text or match virtual maps with physical landmarks.
Solution Approach 2:
The patent transitions navigation information from a two-dimensional screen interface to a three-dimensional real-world projection. By projecting navigation cues onto the road surface, roadside structures, or using augmented reality overlays in the driver's field of view, the system adds spatial dimensionality to navigation information, making it directly comparable with the physical environment and eliminating matching errors.
3Loss of information
If drivers frequently check navigation devices, then navigation information can be received, but driver convenience deteriorates due to the need for frequent attention shifts
Solution Approach 1:
The patent implements preliminary action by projecting navigation information onto the road surface or roadside structures in advance of the required maneuver. Drivers receive turn direction, distance, and timing information before reaching the decision point, allowing them to plan and execute maneuvers smoothly without last-minute attention shifts or sudden steering corrections.
Solution Approach 2:
The navigation system provides self-service by automatically displaying guidance information in the driver's field of view without requiring manual device operation. The system continuously monitors vehicle position and autonomously updates the displayed navigation cues on road signs or projection surfaces, eliminating the need for drivers to manually interact with navigation devices.
