Dynamic Navigation to Moving Targets with Adaptive Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation technologies are limited in navigating to moving target devices, as they primarily focus on fixed locations, lacking efficient real-time route updates and power management for location tracking.
Innovation Solution
Implementing a system where a source device continuously generates and updates a path to a moving target device in real-time by using real-time location updates from the target device, switching between low-accuracy and high-accuracy position tracking based on distance, and utilizing a server to perform complex computations and send updated routing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-accuracy position tracking is used continuously, then navigation accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the position tracking accuracy adjustable and adaptive rather than fixed. The system dynamically switches between high-accuracy and low-accuracy tracking modes based on real-time conditions such as distance to target and movement state, allowing the tracking precision to vary with operational requirements rather than maintaining constant high accuracy
Solution Approach 2:
The patent changes the parameter of position tracking accuracy based on operational context. When the source device is far from the target or both devices are moving in the same direction, the system reduces tracking accuracy to conserve power. When proximity is detected or relative movement creates navigation challenges, the system increases accuracy to ensure safe and effective navigation
2Measurement precision
If route updates are performed frequently, then navigation accuracy is improved, but computational load and power consumption increase
Solution Approach 1:
The patent implements periodic action by updating the navigation route at specific intervals or triggers rather than continuously. Route updates occur periodically or when specific conditions are met (such as distance thresholds or significant position changes), balancing navigation accuracy with reduced computational overhead and power consumption compared to continuous real-time updates
3Reliability
If continuous real-time tracking is maintained, then navigation reliability is improved, but power consumption increases
Solution Approach 1:
The patent makes the tracking intensity dynamic rather than static. The system adjusts tracking intensity based on operational phase: using higher intensity tracking when reliability is critical (such as during final approach or when obstacles are present) and reducing intensity during stable cruising phases, thereby maintaining navigation reliability while optimizing power consumption

AI summary
A source device can navigate towards a moving destination target device, such as when two mobile phones are moving towards each other. The source device can receive an initial position of the target and a route to the target. As the source device and target device simultaneously move, the route can be updated. For example, if a distance of movement exceeds a threshold (e.g., 1 mile) the route can be updated. In another embodiment, a target device can switch between position tracking devices so as to provide less accurate position information, but save power, or provide high accuracy position information at the cost of higher power consumption. Generally, the switching between position tracking devices and the frequency at which the route to the destination point can be based on the distance apart between the source device and target device.
