Solution Overview
Problem
Existing navigation systems are unable to effectively provide navigation services for non-ground-based or multi-modal vehicles, as they cannot reconcile navigation for different travel modes, such as air and ground travel, leading to inefficiencies and increased costs.
Innovation Solution
A navigation system that includes a control unit to calculate both non-terrestrial and ground navigation routes, generating a composite route for multimodal vehicles, and an interface unit to communicate this route, enabling continuous guidance across various travel modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing navigation systems are used for multimodal vehicles, then ground-based navigation can be provided, but navigation services for non-ground-based or multi-modal vehicles cannot be reconciled
Solution Approach 1:
The navigation system is designed to provide universal navigation services across multiple travel modes (ground-based, air, water) by implementing a unified routing algorithm that can handle different transportation modes. The system determines appropriate travel modes based on location data and provides continuous navigation guidance regardless of the specific mode being used, making the system adaptable to multimodal vehicles while maintaining reliable navigation accuracy.
2Reliability
If separate navigation systems are used for different travel modes, then each mode can be optimized, but the system complexity increases and costs rise
Solution Approach 1:
The patent merges separate navigation systems for different travel modes into a single unified navigation system. The routing algorithm integrates ground-based, air, and water travel routing capabilities into one cohesive system that determines the appropriate travel mode based on location data. This combination reduces system complexity and costs while maintaining optimized navigation performance for each specific mode through the unified algorithm.
3Device complexity
If a unified navigation approach is used for all travel modes, then system complexity is reduced, but the ability to provide optimized routing for specific modes is lost
Solution Approach 1:
The unified navigation system employs dynamic routing algorithms that adapt to the specific travel mode being used. The system determines the appropriate travel mode based on location data and dynamically adjusts the routing calculations to optimize for that specific mode's characteristics. This dynamic approach allows the system to maintain low complexity while achieving high routing efficiency for each mode through context-aware algorithm adjustments.

AI summary
A navigation system includes: a control unit configured to calculate a non-terrestrial navigation route for guiding a multimodal vehicle during a non-terrestrial travel segment; calculate a ground navigation route for guiding the multimodal vehicle during a ground travel segment beyond a mode-transition point; generate a composite navigation route based on the non-terrestrial navigation route and the ground navigation route for continuously guiding the multimodal vehicle over the non-terrestrial travel segment and the ground travel segment; and an interface unit, coupled to the control unit, configured to communicate the composite navigation route.
