On-Road Projection System for Tire Path Hazard Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions fail to provide real-time feedback to drivers about their vehicle's relative position to road hazards, making it difficult to avoid damages from potholes and other poor road conditions, resulting in costly maintenance and repairs.
Innovation Solution
An on-road projection system integrated into vehicles, using a projector and computing device to generate a tire path projection on the road ahead, allowing drivers to precisely steer around hazards in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver attempts to precisely steer around road hazards, then vehicle damage can be avoided, but it becomes challenging to maintain lane position and visibility when weather conditions are poor or hazards are small
Solution Approach 1:
The patent introduces an intermediary system (projection system with lane markers and hazard indicators) that mediates between the driver and the road environment. This intermediary provides visual feedback about tire position and hazard location, making it easier for the driver to steer precisely around hazards while maintaining lane position, especially in poor weather conditions
Solution Approach 2:
The projection system provides real-time visual feedback to the driver by displaying lane markers that indicate tire position and hazard indicators that show upcoming road hazards. This feedback loop enables the driver to make precise steering adjustments to avoid hazards while maintaining proper lane position
2Loss of information
If no feedback system is provided, then the system remains simple, but the driver cannot determine or estimate whether the vehicle will encounter poor road conditions
Solution Approach 1:
The patent uses optical copying by projecting visual representations (lane markers and hazard indicators) onto the road surface. This creates a visual copy of the tire path and hazard information that the driver can see, providing road hazard information without requiring complex sensors or processing systems
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 drivers to make informed decisions to avoid road hazards, reducing wear and tear on vehicles and associated maintenance costs by providing real-time visual feedback of tire position relative to road hazards.
Implementation Method 1
The on-road projection system includes a projector and a computing device. The computing device causes the projector to generate a projection on a road as the vehicle is approaching the road hazard.
Data Source
AI summary
A method for visual hazard avoidance of a road hazard is provided. The visual hazard avoidance is implemented by an on-road projection system, which is integrated into a vehicle. The on-road projection system includes a projector and a computing device. The on-road projection system implements the method while the vehicle is in motion. The computing device causes the projector to generate a projection on a road as the vehicle is approaching the road hazard. Note that the projection identifies a tire path of the vehicle. The computing device also causes the projector to terminate the projection on the road once the road hazard in passed.
