Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital navigational map technologies face limitations in sharing map information across platforms, particularly for unmanned ground vehicles (UGVs), due to proprietary systems that hinder efficient and automated cross-platform communication, which affects fleet operations and public safety.
Innovation Solution
Implementing a policy-based navigation control system that allows for the collection of map inputs from mobile devices, applying policies to generate navigation advisories, and using shared overlay maps to facilitate automated, real-time, cross-platform sharing of map information among UGVs and other digital navigational map users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary digital navigational map systems are used by major providers, then each system can maintain its own control and security standards, but information sharing across platforms becomes limited and cumbersome
Solution Approach 1:
The patent introduces a shared overlay map service as an intermediary platform that receives map inputs from multiple subscriber devices using different digital navigational map types. This mediator synthesizes information from various proprietary systems into a unified shared overlay map, enabling cross-platform information sharing while preserving each system's independence and control mechanisms.
2Reliability
If manual specification of map location and recipients is required for sharing, then security and control can be maintained, but the process becomes cumbersome and inefficient
Solution Approach 1:
The system implements automated policies that enable subscriber devices to automatically share map information based on predefined criteria and conditions. The shared overlay map service automatically processes map inputs from multiple sources, synthesizes them, and distributes relevant information to appropriate subscribers without requiring manual intervention, thus maintaining control while significantly improving ease of operation.
3Productivity
If automated cross-platform sharing of map information is implemented, then efficiency and public safety gains can be realized, but system complexity increases
Solution Approach 1:
The patent segments the complex cross-platform sharing system into distinct functional components: subscriber devices that generate map inputs, a shared overlay map service that processes and synthesizes information, and policy mechanisms that govern information flow. This segmentation allows each component to be developed and maintained independently, managing overall system complexity while enabling automated cross-platform information sharing.
4Adaptability or versatility
If multiple digital navigational map types are integrated into a shared overlay map, then comprehensive information coverage is improved, but data synthesis and processing complexity increases
Solution Approach 1:
The shared overlay map service is designed as a universal platform capable of receiving and processing multiple digital navigational map types simultaneously. It implements a standardized interface and synthesis process that can handle diverse map data formats, enabling comprehensive information coverage across different platforms while managing data synthesis complexity through a unified processing approach.
Data Source
AI summary
The described technology is generally directed towards policy based navigation control. Map inputs including, e.g., information about blocked routes or other map information, can be collected from mobile devices. Policies can be applied to the map inputs in order to generate navigation advisories that synthesize information from multiple map inputs. For example, a size and shape of a route blockage zone can be determined from multiple discrete map inputs. In some embodiments, the techniques disclosed herein can be applied in connection with shared overlay maps to support automated, real-time, cross-platform sharing of map information, including navigation advisories, among digital navigational map users, including but not limited to unmanned ground vehicles.
