Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional geolocation methods, such as GPS, are inadequate for tracking objects in motion or in environments where line-of-sight visibility is limited, like enclosed structures or moving vehicles, as they require complex calculations and may not provide accurate location information in dynamic scenarios.
Innovation Solution
The use of inter-device radio frequency communication between stationary beacons and a tracking element, combined with virtualized three-dimensional mapping, allows for accurate triangulation and real-time location tracking across the X, Y, and Z planes, enhancing geolocation functionality in various environments, including cruise ships and multi-story buildings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional GPS-based geolocation methods are used, then global positioning capability is provided, but accurate tracking in enclosed structures or moving vehicles is inadequate
Solution Approach 1:
The system divides the tracking environment into multiple zones with stationary radio frequency elements distributed throughout enclosed structures or vehicles. Each element independently contributes to triangulation calculations, enabling accurate tracking within specific segments of the overall environment rather than relying on a single global system.
Solution Approach 2:
The patent introduces stationary radio frequency elements as intermediary components between the tracking element and the final location determination. These intermediaries relay radio frequency signals and enable triangulation calculations, serving as mediators that make tracking possible in environments where direct GPS satellite communication is blocked.
2Measurement precision
If GPS triangulation is used for moving objects, then location tracking is provided, but complex mathematical calculations are required and accuracy deteriorates in motion
Solution Approach 1:
The system pre-establishes a network of stationary radio frequency elements at known locations within the tracking environment before the tracking element moves. These elements are预先 configured to provide reference points for triangulation, eliminating the need for complex real-time calculations during motion and enabling continuous accurate tracking.
Solution Approach 2:
The patent creates a virtual model of the physical environment by mapping the positions of stationary radio frequency elements in three-dimensional space. This virtual representation copies the essential geometric relationships needed for triangulation, allowing the system to perform simplified calculations based on pre-stored spatial data rather than complex real-time mathematics.
