Navigation System for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedestrian safety in mixed-user environments is compromised due to collisions with faster-moving vehicles and other users, as existing navigation systems fail to effectively prevent intersections that lead to collisions.
Innovation Solution
A navigation system that utilizes a central processing server to receive and compare path information from multiple users, identifying potential collision points and sending navigation guidance to users via mobile applications to avoid these intersections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic signals are used to regulate vehicle and pedestrian interactions, then collision regulation is improved, but compliance is poor and mistakes occur
Solution Approach 1:
The system continuously receives real-time location and path data from multiple users, processes this information centrally, and provides immediate navigation instructions back to users. This closed-loop feedback mechanism replaces static traffic signals with dynamic, adaptive guidance that adjusts to current conditions and user behavior, ensuring reliable collision prevention without requiring strict rule compliance
Solution Approach 2:
Each user receives personalized navigation instructions tailored to their specific path and potential collision risks. The system empowers individual users with real-time guidance based on their own movement patterns and the movements of others, eliminating the need for centralized traffic signal control and improving compliance through personalized, context-aware instructions
2Reliability
If navigation system provides real-time path monitoring and collision warnings to all users, then pedestrian safety is improved, but system complexity and computational requirements increase
Solution Approach 1:
A central processing server acts as an intermediary that consolidates path data from all users, performs complex collision risk analysis, and generates navigation instructions. This centralized intermediary handles the computational complexity centrally rather than requiring complex processing in each user device, thereby improving safety through comprehensive monitoring while keeping individual user devices simple
Solution Approach 2:
The central processing server performs multiple functions: receiving location data, determining user paths, predicting future positions, identifying collision risks, and generating navigation instructions. By consolidating these diverse functions in a single multi-functional system, the patent achieves comprehensive safety monitoring without proliferating complex components across multiple devices

AI summary
A system for preventing collisions between users of the system. The system includes a central processing server receiving first path information relating to a first user and second path information relating to a second user. The central processing server determines a projected path of each user. The central processing server compares the projected paths identifies points of intersection, which are locations that put the users at risk of a collision. The central processing server sends navigation directions to avoid the collision to the first user.
