Solution Overview

Problem

Existing Mobile Satellite Services (MSS) systems with Ancillary Terrestrial Components (ATC) face challenges in providing flexible and feature-rich navigation services due to limitations in multicast transmissions and interactive communications across satellite and terrestrial networks, restricting user preferences and geographic coverage.

Innovation Solution

A hybrid satellite and terrestrial communication system that processes historical trip data to select points-of-interest (POI) based on community-of-interest ratings, allowing for graphical representation and navigation data display, enabling users to choose routes and destinations efficiently through a mobile or in-vehicle system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a hybrid satellite and terrestrial communication system is used to provide navigation services, then geographic coverage is improved, but system complexity increases

Engineering Contradiction:

Improvegeographic coverageVSAvoidsystem complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The navigation system is segmented into satellite and terrestrial components, each handling specific functions. The satellite portion provides broad geographic coverage, while the terrestrial portion handles detailed navigation services, allowing the system to achieve wide coverage without requiring the entire system to be overly complex.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hybrid communication system is designed to provide multiple services including navigation, voice communication, and data transmission through a unified platform. This multi-functionality allows the system to achieve broad geographic coverage while sharing infrastructure and reducing overall system complexity through resource consolidation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If multicast transmissions are implemented across satellite and terrestrial networks, then service efficiency is improved, but implementation difficulty increases

Engineering Contradiction:

Improveservice efficiencyVSAvoidimplementation difficulty

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

A network controller acts as an intermediary to manage multicast transmissions between satellite and terrestrial networks. This mediator coordinates the transmission processes, handles protocol conversions, and manages resource allocation, thereby improving service efficiency while reducing the implementation burden on individual network components.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If interactive communications with individual users are supported, then user service quality is improved, but network complexity increases

Engineering Contradiction:

Improveuser service qualityVSAvoidnetwork complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where user requests and responses are automatically routed and managed through the hybrid network. This allows individual user interactions to be handled efficiently with minimal manual intervention, improving service quality while the automated feedback loops manage network complexity.

Inventive Principle:

Principle #23Feedback

4Adaptability or versatility

If navigation search criteria are expanded to include more user preferences, then navigation flexibility is improved, but processing requirements increase

Engineering Contradiction:

Improvenavigation flexibilityVSAvoidprocessing requirements

Core Design Contradiction:

Adaptability or versatilityVSPower

Solution Approach 1:

The system pre-processes and stores navigation data according to common user preferences and criteria before actual navigation queries are made. By organizing data in advance based on anticipated user needs (such as preferred routes, destinations, and travel preferences), the system provides flexible navigation options without requiring intensive real-time processing when users actually search for directions.
