Geofence Geometry Decoupling for Accurate Physical Map Overlays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geofencing technologies are limited by centroid-based definitions that fail to accurately represent intended areas, leading to inconsistent content delivery and privacy issues, as they do not effectively associate geofences with the intent and context of content accessibility.
Innovation Solution
Geofences are defined by a plurality of geographic designators associated with unique IPv6 addresses, enabling precise boundary delineation and rule enforcement through a fencing agent embedded in drones or devices, ensuring compliance with geofence rules and metadata storage for notification systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If centroid-based geofence definitions are used, then the system is simple to implement, but the geofence boundaries fail to accurately represent intended areas
Solution Approach 1:
The geofence is segmented from a single centroid point into multiple geographic designators (vertices) that collectively define the boundary. This segmentation allows the geofence to accurately represent complex intended areas while maintaining systematic implementation through structured coordinate data.
Solution Approach 2:
The geofence definition transitions from zero-dimensional (centroid point) to two-dimensional (boundary polygon) representation. This dimensional change enables accurate depiction of area boundaries while the underlying data structure remains manageable through coordinate arrays.
2Measurement precision
If geofences are defined by multiple geographic designators with IPv6 addresses, then boundary accuracy improves, but data storage and processing complexity increases
Solution Approach 1:
The geographic designator structure serves multiple functions simultaneously: it defines boundary geometry, provides location identification through IPv6 addresses, and enables content delivery decisions. This multi-functionality reduces the need for separate data structures for each purpose.
Solution Approach 2:
The patent uses standardized data structure templates for geographic designators that can be replicated and reused across multiple geofences. This copying approach simplifies data management despite the increased precision requirements.
3Measurement precision
If precise geofence boundaries are implemented, then content delivery accuracy improves, but privacy issues arise from detailed location tracking
Solution Approach 1:
The system applies different levels of precision locally: geographic designators provide precise boundary definitions for content delivery decisions, while the actual user location tracking can be performed at coarser levels when precision is not required, thereby reducing privacy intrusion.
Solution Approach 2:
The geofence boundary acts as an intermediary between precise location data and content delivery decisions. Instead of directly using detailed user location information for all decisions, the system mediates through geofence membership determination, which can be performed with less precise location data.
4Productivity
If geofences are decoupled from maps, then geofence delivery efficiency improves, but system integration complexity increases
Solution Approach 1:
The system segments geofence data from map data into separate delivery streams. Geofences are delivered independently as geometric definitions, while maps provide contextual visualization. This segmentation enables optimized delivery paths for each data type.
Solution Approach 2:
A geofence management server acts as an intermediary between the geofence definition source and the client devices. This intermediary handles the decoupling logistics, managing geofence deliveries separately from map deliveries while maintaining proper associations through coordinate reference systems.
