Vehicle Obstruction Warning System with Dynamic Suspension Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reporting and addressing road obstructions, such as potholes, are inefficient, leading to delays in clearance and insufficient warning time for drivers to avoid these hazards, especially in large metropolitan areas with severe weather conditions.
Innovation Solution
An in-the-road obstruction warning unit that automatically detects and reports obstructions, providing timely notifications to drivers through various sensors and communication systems, including accelerometers, microphones, and GPS, to alert them of upcoming hazards and potentially adjust vehicle suspension or control systems for avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers manually report road obstructions to the city, then the obstructions can be cleared, but there is considerable delay between reporting and clearance
Solution Approach 1:
The system performs preliminary detection and reporting of obstructions automatically before drivers encounter them. Sensors detect obstructions and the system reports their locations in advance, enabling proactive clearance planning and reducing the time between obstruction occurrence and city response.
Solution Approach 2:
The system establishes a feedback loop where sensor data about obstructions is continuously collected, analyzed, and reported to both drivers and city authorities. This real-time feedback mechanism enables faster response times and coordinated clearance actions based on actual road conditions.
2Ease of operation
If GPS-based guidance devices are used, then drivers can be directed to reroute, but they do not direct drivers to reroute for passable obstructions
Solution Approach 1:
The system changes the parameters used for routing decisions by incorporating real-time obstruction detection data from sensors. Instead of relying solely on predetermined GPS routes, the system dynamically adjusts routing recommendations based on detected obstruction locations, severity, and passability characteristics.
Solution Approach 2:
The obstruction detection system acts as an intermediary between the road environment and the driver's navigation system. It processes sensor data about obstructions and translates this information into actionable routing guidance, bridging the gap between physical road conditions and digital navigation instructions.
3Loss of information
If accelerometers are used to detect obstructions after impact, then obstruction locations can be reported, but drivers receive no warning before encountering them
Solution Approach 1:
The system performs preliminary detection of obstructions using sensors positioned to detect them before vehicle impact. By detecting obstructions in advance and calculating their locations, the system can provide warnings to drivers before they encounter the hazards, eliminating the need to wait for impact occurrence.
Solution Approach 2:
The system replaces purely mechanical impact-based detection (accelerometers triggered by collision) with a hybrid approach incorporating optical, acoustic, or other non-contact sensors that can detect obstructions before physical contact occurs, enabling advance warning capability.

Function Achieved in This Case
This solution enables drivers to receive timely warnings, allowing them to take appropriate action to avoid obstructions and reduces the impact of unavoidable hits by modifying vehicle suspension or control systems, thereby enhancing safety and reducing damage.
Implementation Method 1
The app uses the phone's accelerometer to sense when a bump is hit
Implementation Method 2
microphones, and GPS, to alert them of upcoming hazards
Implementation Method 3
The location of the bump, as determined using global positioning signals (GPS), is transmitted to a remote server

AI summary
A driver warning system automatically detects the existence of in-the-road, passable obstructions and provides timely notification to a driver in proximity of such an in-the-road, passable obstruction prior to it being encountered with sufficient warning time for the driver to avoid the in-the-road, passable obstruction. To detect in-the-road, passable obstructions, the warning unit of a driver whose vehicle hits an in-the-road, passable obstruction will automatically generate a signal that is indicative of the existence of the in-the-road, passable obstruction and its location. This signal may be transmitted to a server, which contains a database of located obstructions. The collected information about the detected in-the-road, passable obstructions are provided to various warning units, so that they, knowing the driver location, e.g., based on global positioning system (GPS), can provide the driver with a warning of any upcoming in-the-road, passable obstructions with sufficient lead time for the driver to avoid hitting the obstruction.
