Vehicle Projection Orientation Correction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often face difficulties in navigating from their vehicle to a destination due to unclear directions, especially when the exit location is unfamiliar, and existing navigation systems do not provide effective visual guidance on the ground.
Innovation Solution
A vehicle-mounted projection system that projects a map with directions onto the ground, automatically rotating the image to align with the determined route or orient north, allowing users to easily follow the path to their destination upon exiting the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user parks the vehicle at a destination, then the vehicle can be positioned at the location, but the user must walk a significant distance to reach the final destination
Solution Approach 1:
The patent projects navigation information from the vertical display plane (screen) onto the horizontal ground plane, creating a three-dimensional navigation experience. This allows users to see directions directly on the ground while walking, transforming the navigation interface from a static 2D screen to a dynamic 3D ground projection that moves with the user's position.
Solution Approach 2:
The ground projection serves as an intermediary between the vehicle's navigation system and the user's physical movement. Instead of requiring the user to constantly check a screen inside the vehicle or interpret abstract map directions, the system projects turn-by-turn directions directly onto the ground path the user will walk, making navigation intuitive and immediate.
2Loss of information
If traditional navigation systems provide directions on a screen, then navigation information is available, but the directions are not clear when the exit location is unfamiliar
Solution Approach 1:
The system uses color-coded projections to convey different types of navigation information. Blue projections indicate the current walking path, green projections indicate the destination or final destination point, and yellow projections may indicate alternative routes or points of interest. This color-coding system makes direction information immediately distinguishable and easy to follow.
Solution Approach 2:
The system pre-calculates and projects the complete walking route from the vehicle exit to the final destination before the user begins walking. This allows users to see the entire path ahead of time, understand where they need to go, and follow the projected guide lines on the ground without needing to make real-time navigation decisions.
3Ease of operation
If the projected image is not rotated, then the projection system is simple, but the user cannot easily discern direction information
Solution Approach 1:
The projection system dynamically adjusts the orientation and angle of projected directions based on the user's current position, movement direction, and the geometry of the walking path. As users move along the route, the projection system rotates and reorients the directional arrows and path indicators to始终保持 alignment with the intended walking direction, making the navigation information always readable and relevant.
Solution Approach 2:
The system continuously monitors the user's position and movement through sensors and GPS data, then uses this feedback to automatically adjust the projection orientation. This closed-loop control ensures that the projected directions remain accurately aligned with the actual path, accounting for variations in user movement speed, direction changes, and environmental factors.
