Mobility Link Navigation Across No-Vehicle Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems cannot provide travel paths in areas where vehicle travel is not possible, such as no-vehicle zones or backwoods, and do not support mobility links between vehicle terminals and vehicle-carried moving object terminals.
Innovation Solution
A smart mobility link system that includes a vehicle terminal with GPS, GIS, and user input capabilities to calculate and display a travel path to a parking location, and then relays mobility information to a vehicle-carried moving object terminal via short-range wireless communication to continue providing the travel path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a navigation system provides a travel path using only vehicle travel, then the vehicle can reach most destinations efficiently, but it cannot provide travel paths in areas where vehicle travel is not possible (no-vehicle zones, backwoods)
Solution Approach 1:
The travel path is segmented into two distinct segments: a first travel path from the starting point to a transfer point that can be traveled by vehicle, and a second travel path from the transfer point to the destination that can be traveled by a vehicle-carried moving object. This segmentation allows the system to provide continuous navigation coverage even in areas where vehicle travel is restricted.
Solution Approach 2:
A transfer point is introduced as an intermediary location where the user transitions from vehicle travel to vehicle-carried moving object travel. This intermediary enables the system to bridge the gap between areas accessible by vehicle and areas accessible only by moving objects, thereby expanding overall path availability.
2Adaptability or versatility
If the system supports multiple transportation modes (vehicle and vehicle-carried moving object), then it can provide continuous travel paths, but the system complexity increases due to coordination between different terminals
Solution Approach 1:
The navigation functions for vehicle travel and moving object travel are merged into a single integrated system. The server generates both the first travel path (for vehicle) and the second travel path (for moving object) as part of one unified navigation process, and the vehicle terminal coordinates both segments, reducing overall system complexity despite supporting multiple modes.
Solution Approach 2:
The vehicle terminal is designed with multi-functionality to serve dual purposes: it provides navigation for vehicle travel and also acts as a communication bridge to transmit the second travel path to the moving object terminal. This universal design reduces the need for separate specialized systems.
3Ease of operation
If the vehicle terminal provides the complete travel path, then the navigation is simple, but it cannot guide the user through the remaining distance in no-vehicle zones
Solution Approach 1:
The vehicle terminal acts as an intermediary that receives the complete travel path information from the server, processes it into two segments, and then transmits the relevant second travel path information to the moving object terminal. This intermediary role maintains navigation simplicity for the user while ensuring that remaining path information is preserved and transmitted appropriately.

AI summary
Provided is a smart mobility link system which provides a travel path through a vehicle terminal installed in a vehicle up to a location at which parking is allowed, and mobility is relayed to a vehicle-carried moving object terminal which is installed in a vehicle-carried moving object over a remaining distance so that the travel path can be continuously provided. Accordingly, a user can be guided through a travel path even in an area in which vehicle travel is not possible without additional manipulation of the user.
