Movement Assistance Device Route Selection for On-Time Vehicle Meeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement assistance technologies only present users with a single route to a meeting location, limiting their options for reaching the destination on time.
Innovation Solution
A movement assistance device and method that calculate multiple routes from the user's current location to the meeting location, determining which routes allow the user to arrive on time with a dispatched vehicle, and presenting these options to the user for selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one route is presented to the user, then the system complexity is reduced, but the user's movement options are limited
Solution Approach 1:
The patent segments the route information by dividing multiple possible routes into separate, distinct route options. Each route is calculated and presented as an independent choice to the user, allowing the system to maintain simplicity in presenting individual routes while providing diversity through multiple segmented options.
Solution Approach 2:
The system dynamically adjusts the number and type of routes presented based on real-time conditions. The route calculation unit can generate different numbers of routes depending on traffic conditions, user preferences, and other dynamic factors, making the system adaptable without requiring complex manual configuration.
2Adaptability or versatility
If multiple routes are calculated and presented to the user, then the user's movement options increase, but the calculation time and processing load increase
Solution Approach 1:
The system calculates a partial set of routes rather than exhaustively calculating all possible routes. The route calculation unit generates a sufficient number of viable route options (e.g., 3-5 routes) that meet the user's requirements, rather than calculating every theoretically possible path, thus reducing calculation time while still providing adequate choice.
Solution Approach 2:
The system performs preliminary route calculations by pre-processing route data and storing it in advance. When a user requests routes, the system retrieves and filters pre-calculated route information rather than performing complete route calculations from scratch, significantly reducing the time required to present multiple route options.
3Reliability
If multiple routes are presented with detailed information, then the user can make better decisions, but the information processing complexity increases
Solution Approach 1:
The system applies local quality by providing different levels of information detail for different routes based on their characteristics. For example, routes with special conditions (traffic congestion, construction zones) receive more detailed information, while standard routes receive concise information. This allows the system to improve decision accuracy where needed without uniformly increasing information processing complexity across all routes.

AI summary
A movement assistance device guides a user to a meeting location for meeting a vehicle. The movement assistance device calculates a first required time until the vehicle arrives at the meeting location, and a plurality of routes from the user's current location to the meeting location. The movement assistance device calculates a second required time for the user to arrive at the meeting location from the user's current location for each route. The movement assistance device then determines the route associated with the second required time as a route via which the vehicle could be met on time when a second required time is the same as or shorter than the first required time. The movement assistance device then causes the communication device to output information that indicates the route or routes determined to be the route or routes via which the vehicle could be met on time.
