Solution Overview

Problem

Current systems lack the capability to predict the course of a moving mobile device and navigate to intercept it, especially when both the user and the device are in motion.

Innovation Solution

A method and apparatus that utilize positioning data from a target device to generate a predicted target course, allowing an intercept device to calculate an intercept course that intersects with the target course at a different intercept destination, enabling navigation to intercept the moving target device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a system tracks the current location of a moving target device, then the position information can be obtained, but the system cannot predict the future course or intercept the moving device

Engineering Contradiction:
Improveposition information accuracyVSAvoidcourse prediction capability
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system performs preliminary actions by calculating a predicted target course based on current position and destination information before the interception occurs. This allows the intercept device to plan its intercept course in advance, rather than merely reacting to current position data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system transitions from static position tracking to dynamic course prediction by continuously updating the predicted target course as the target device moves. The intercept course is dynamically adjusted based on the evolving position and movement pattern of the target device.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the intercept device navigates to the specified destination geographic location, then it reaches the target's destination, but it cannot intercept the moving target device which has already passed or will not be at that location

Engineering Contradiction:
Improvenavigation simplicityVSAvoidinterception success rate
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system calculates the intercept destination and intercept course in advance based on predicted target position, allowing the intercept device to take preliminary navigation actions that will result in successful interception, rather than simply navigating to the original destination.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes the destination parameter from the original specified destination geographic location to a calculated intercept destination that accounts for the target device's movement. This parameter transformation enables the intercept course to intersect with the target's predicted path.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If the system uses a centralized remote location to receive and relay position information, then position data can be collected, but real-time course prediction and interception navigation cannot be performed

Engineering Contradiction:
Improveposition data volumeVSAvoidsystem architecture complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The system extracts the course prediction and intercept navigation functions from the centralized remote location and implements them locally at the intercept device. This eliminates the need for complex centralized processing while maintaining real-time interception capability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A system and method of navigating to a destination is provided. The method includes determining a target course for a moving target device using target positioning data and generating an intercept course using the target course and intercept positioning data received from an intercept device. The intercept course intersects the target course at a moving destination or fixed intercept destination. The target course and the intercept course are generated by the intercept device or a remote device which is remote from the intercept device
