Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems often route vehicles through hazardous areas, such as high-risk intersections and road construction zones, exposing drivers to collision risks due to unquantifiable environmental factors and lack of real-time risk assessment.
Innovation Solution
A system calculates a risk index for various areas based on historical collision data, traffic patterns, and sensor information, allowing for the selection of routes that avoid hazardous zones and providing real-time notifications to drivers through electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional navigation systems are used to provide routes, then route guidance functionality is provided, but vehicles are routed through hazardous areas exposing drivers to collision risks
Solution Approach 1:
The system performs preliminary risk assessment by calculating risk indices for various road segments and areas before the vehicle reaches them. Historical collision data, traffic patterns, and environmental factors are analyzed in advance to identify hazardous zones, allowing the navigation system to provide safe routes that avoid these areas before the driver encounters them.
Solution Approach 2:
The system continuously monitors real-time traffic data, collision reports, and environmental conditions to update risk indices dynamically. This feedback mechanism allows the navigation system to adjust route recommendations based on current safety conditions, ensuring that drivers are guided away from emerging hazardous areas while maintaining reliable route guidance functionality.
2Reliability
If risk index calculation is implemented to identify hazardous areas, then collision risk is reduced, but system complexity increases
Solution Approach 1:
The system leverages existing multi-functional data sources including historical collision databases, real-time traffic monitoring infrastructure, and environmental sensors that serve multiple purposes. By utilizing these existing systems for risk assessment in addition to their primary functions, the patent reduces the need for dedicated complex hardware while achieving reliable collision risk reduction.
Solution Approach 2:
The patent introduces a risk index calculation module that acts as an intermediary between raw data from multiple sources (collision databases, traffic sensors, environmental monitors) and the navigation routing system. This intermediary processes and synthesizes diverse data into a unified risk assessment, simplifying the integration complexity while maintaining comprehensive hazard identification capabilities.
3Reliability
If real-time risk assessment is provided to drivers, then safety is improved, but information processing requirements increase
Solution Approach 1:
The system extracts only the most critical risk factors and simplified metrics from comprehensive real-time data streams, focusing on key hazards that pose immediate threats to safety. By selectively processing essential information rather than analyzing all available data in real-time, the system maintains accurate safety assessment while reducing computational energy consumption in mobile devices.
Solution Approach 2:
The system implements partial real-time processing by continuously monitoring critical safety parameters while updating risk assessments at optimized intervals rather than continuously. This approach provides timely safety information to drivers without requiring excessive real-time processing power, balancing safety responsiveness with energy efficiency in mobile computing environments.
