Vehicle Height Alerts for Low-Clearance Overpass Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, particularly tall vehicles like trucks or buses, frequently collide with overpasses due to misjudgment of vehicle height or clearance, inadequate signage, navigation errors, distractions, or carrying oversized loads, leading to significant damage.
Innovation Solution
A method that identifies the total vehicle height and compares it to proximal road clearance heights, generating warnings through a mobile application when a potential collision is detected, using GPS data and overpass information services to guide safe navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers rely on traditional warning signs and manual height judgment, then the system is simple and easy to operate, but collision risk increases due to misjudgment and inadequate signage
Solution Approach 1:
The patent introduces a mobile application as an intermediary between the driver and the road environment. The application serves as a mediator that automatically获取s vehicle height information, retrieves road clearance data, performs comparisons, and delivers warnings - eliminating the need for drivers to manually judge heights while keeping the underlying system relatively simple
Solution Approach 2:
The system enables self-service by allowing the mobile application to automatically obtain vehicle height information from various sources (vehicle specifications, GPS data, load information) without requiring manual input from the driver. The application independently performs all calculations and generates warnings autonomously
2Reliability
If drivers pay full attention to road signs and warnings, then collision prevention improves, but driving efficiency decreases due to distractions from navigation devices and passengers
Solution Approach 1:
The patent replaces the mechanical system of visual attention and cognitive judgment with an automated electronic system. Instead of relying on drivers to visually scan signs and mentally calculate clearance, the mobile application automatically retrieves data, performs comparisons, and issues warnings through audible or visual alerts, freeing the driver's attention
Solution Approach 2:
The system implements feedback by continuously monitoring the vehicle's location via GPS, comparing current position against stored road clearance data, and providing real-time warnings when potential collisions are detected. This closed-loop feedback mechanism ensures timely alerts without requiring constant driver attention to road signs
3Measurement precision
If navigation systems provide detailed route information, then routing accuracy improves, but drivers may be led onto low clearance routes without adequate warning
Solution Approach 1:
The patent applies preliminary action by pre-loading road clearance data for all roads proximal to the vehicle's route before the journey begins or during navigation. The mobile application has access to clearance information in advance, allowing it to identify and warn about low clearance areas before the vehicle reaches them, rather than reacting after the fact
Solution Approach 2:
The system implements preliminary anti-action by proactively identifying routes with low clearance areas and warning drivers before they encounter potential hazards. The mobile application compares the vehicle's height against upcoming road clearances and alerts drivers in advance, allowing them to take corrective action before entering dangerous zones
Data Source
AI summary
A method generates a warning that a total vehicle height of a vehicle may exceed a clearance height of a road. The method begins with identifying the total vehicle height. The method then downloads the clearance height of all roads proximal to the vehicle. The vehicle height is compared to the clearance heights downloaded. A warning is generated when the step of comparing identifies at least one clearance height that is less than the vehicle height.
