Solution Overview
Problem
Current navigation systems for visually impaired individuals fail to provide accurate and adaptive route guidance, especially in dynamic and indoor environments, lacking effective obstacle detection and avoidance capabilities.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional map programs provide turn by turn instructions at selected points of interest, then route guidance is provided, but obstacle detection and avoidance capability is lacking
Solution Approach 1:
The patent combines traditional map-based route guidance with sensor-based obstacle detection systems. The navigation system integrates GPS/location data with sensor inputs (ultrasonic sensors, LIDAR, cameras) to create a hybrid system that provides both route instructions and real-time obstacle awareness, resolving the contradiction between reliable route guidance and adaptability to dynamic obstacles
Solution Approach 2:
The system continuously monitors the environment through sensors and adjusts the navigation route in real-time based on detected obstacles. This feedback mechanism allows the system to maintain reliable route guidance while adapting to changing conditions, as the path is dynamically modified when obstacles are detected
2Extent of automation
If self-driving cars autonomously navigate routes, then vehicle navigation is automated, but processing and accounting for dynamic obstacles remains difficult
Solution Approach 1:
The patent divides the navigation system into separate functional modules: route guidance module, obstacle detection module, and path planning module. This segmentation allows each component to specialize in its function, with the obstacle detection module independently processing sensor data to identify dynamic obstacles, while the path planning module adjusts the route based on this information
Solution Approach 2:
The system performs preliminary actions by detecting and classifying obstacles before they become immediate hazards. The sensor system continuously scans the environment and identifies potential obstacles in advance, allowing the navigation system to plan alternative routes proactively rather than reactively
3Adaptability or versatility
If navigation systems are designed for standard routes via streets, then outdoor navigation is supported, but indoor navigation amongst changing environments is not adequately covered
Solution Approach 1:
The patent designs a universal navigation system that can operate in multiple environments (outdoor streets and indoor spaces) using the same core architecture. The system uses sensor fusion and adaptive algorithms that work whether the user is navigating a familiar street or an unfamiliar indoor space with dynamic obstacles, making the system versatile across different contexts
