Follow Me Navigation System With Dynamic Route Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems lack a seamless method for sharing and following personalized routes, especially in situations where real-time traffic avoidance is necessary, and verbal or written directions may not be sufficient for unfamiliar individuals.
Innovation Solution
A system comprising a direction recording device and a follow me device, connected via a server, that records and transfers route information, including GPS data, annotations, and multimedia, allowing users to follow the same route dynamically, even when parties are not traveling simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If verbal or written directions are provided, then the complexity of the navigation system is reduced, but the accuracy and reliability of route guidance deteriorate for unfamiliar individuals
Solution Approach 1:
The system creates a digital copy of the route taken by a familiar person (leader) and transmits it to followers' devices. This copy includes GPS coordinates, turn-by-turn directions, and route annotations, allowing followers to replicate the exact path without requiring real-time verbal guidance or complex manual navigation setup.
Solution Approach 2:
The system introduces a server as an intermediary that receives route data from the leader's device, processes it, and distributes it to followers' devices. This mediator handles the complex tasks of route optimization, format conversion, and real-time updates, keeping individual user devices simple while ensuring reliable route guidance.
2Adaptability or versatility
If real-time route information is shared dynamically, then the adaptability to traffic conditions improves, but the loss of time for data transmission and processing increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating alternative routes and pre-processing route data while the leader is still traveling. The server prepares multiple route options and formats route information in advance, so that when traffic conditions change, pre-computed alternatives can be quickly transmitted to followers without significant delay.
Solution Approach 2:
The system maintains continuous route information transmission from the leader's device through the server to followers' devices throughout the journey. This continuous data flow ensures that route updates are provided in real-time without interruption, allowing followers to continuously adapt their paths based on current traffic conditions while minimizing gaps in guidance.
3Loss of information
If detailed route information including multimedia is recorded and transferred, then the completeness of navigation data improves, but the quantity of data to be processed increases
Solution Approach 1:
The system segments route information into distinct categories: essential navigation data (GPS coordinates, turn directions), supplementary information (annotations, photos), and metadata (time stamps, location markers). This segmentation allows the system to prioritize transmission of essential data while optionally including supplementary information, reducing overall data volume while maintaining navigation completeness.
Solution Approach 2:
The system applies different quality levels to different parts of the route data. Critical navigation points (intersections, turns) receive high-detail information with multiple data types, while straight segments receive minimal data. This local quality adjustment ensures complete navigation information is provided where needed while reducing total data volume in low-complexity sections.

AI summary
A first navigation device records first direction information as the first navigation device traverses a route from a first location to a second location, and transmits the first direction information to a second navigation device while the second navigation device is following the first navigation along the route. After recording the first direction information and while transmitting the first direction information, the first navigation device records second direction information as the first navigation device traverses the route from the second location to a third location. The first navigation device transmits the second direction information to the second navigation device. The first direction information and the second direction information include information that allows the second navigation device to follow the route traversed by the first navigation device.
