Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital navigational maps are limited by proprietary systems that hinder cross-platform sharing of map information, especially for unmanned ground vehicles (UGVs), necessitating manual human intervention and lacking automated efficiency and safety in sharing map updates across different fleets.
Innovation Solution
A shared overlay map service with a truth maintenance module enhances credibility of map inputs by calculating credibility values based on various factors, filtering and promoting only credible updates across multiple devices, allowing seamless sharing and integration of map updates across different navigation systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary digital navigational map systems are used, then each system maintains its own map information securely, but cross-platform sharing of map information becomes limited and cumbersome requiring manual human intervention
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 navigational map systems. This mediator enables automated cross-platform sharing by translating and standardizing map information from proprietary systems into a common format that can be shared across different fleets and platforms without manual intervention.
Solution Approach 2:
The shared overlay map service provides universal functionality by serving multiple subscriber devices with different navigational map systems through a single platform. It handles diverse map input formats, processes credibility assessments, and distributes relevant map information to various types of users including human users and unmanned ground vehicles across different ecosystems.
2Productivity
If automated cross-platform sharing of map information is implemented, then efficiency and safety gains are realized, but additional complexity in system integration and control is required
Solution Approach 1:
The patent segments the complex sharing system into distinct functional modules: subscriber devices that generate map inputs, a shared overlay map service that processes and manages the information, and a truth maintenance module that assesses credibility. This segmentation allows each component to handle specific tasks independently, reducing overall system integration complexity while enabling automated cross-platform sharing.
Solution Approach 2:
The shared overlay map service acts as an intermediary that manages the complexity of cross-platform integration. It handles format translation, credibility assessment coordination, and information distribution, thereby shielding individual systems from the complexity of direct multi-platform integration while enabling efficient automated sharing.
3Area of stationary object
If all map inputs from multiple devices are shared, then comprehensive map coverage is achieved, but credibility and relevance of shared information cannot be guaranteed
Solution Approach 1:
The truth maintenance module implements a feedback mechanism that continuously assesses the credibility of map inputs based on multiple factors including source reliability, consistency with existing map data, and temporal relevance. This feedback loop enables the system to filter and prioritize high-quality information while maintaining comprehensive coverage, as the credibility assessment guides which map inputs are promoted for sharing.
Solution Approach 2:
The system changes the parameter of information quality by introducing credibility scoring that transforms raw map inputs into graded information with associated reliability metrics. This parameter transformation allows the system to maintain comprehensive geographic coverage while ensuring that shared information meets minimum credibility thresholds, as inputs below certain credibility levels are filtered or flagged for verification.
4Ease of operation
If manual specification of map location and recipients is required, then control over information sharing is maintained, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The shared overlay map service implements self-service functionality by automatically determining which map inputs are credible and which subscriber devices should receive the information. The system autonomously performs location identification, recipient selection based on relevance criteria, and information distribution, eliminating the need for manual specification while maintaining appropriate control through credibility-based filtering.
Solution Approach 2:
The system uses feedback mechanisms to automatically route map information to appropriate recipients. The truth maintenance module analyzes credibility factors and automatically determines distribution targets based on device location, user preferences, and relevance criteria, thereby eliminating manual specification steps while ensuring information reaches the most appropriate users efficiently.

AI summary
The described technology is generally directed towards digital map truth maintenance. Map inputs shared among multiple users of a shared overlay map service can have a range of credibility, from not credible to highly credible. The disclosed digital map truth maintenance technologies can be used to enhance credibility of shared map inputs. Credibility values can be calculated for map inputs, based on any of multiple factors. Map inputs having sufficiently high credibility, such as a credibility value determined to be above a threshold value, can be shared among multiple mobile devices.
