User Guidance System with Attraction-Based Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user guidance systems cannot guide users for purposes other than a stopover and lack flexibility in routing based on user preferences and attractions, leading to inefficient navigation.
Innovation Solution
A user guidance system that includes modules for acquiring departure and destination information, generating candidate routes, calculating points for desired or undesired routes and points, and providing point information to users based on attraction desirer settings, allowing for flexible routing and attraction management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bypass route guidance system is used to guide users to stores on bypass routes, then users can be directed to stopover locations during traffic jams, but the system cannot guide users for purposes other than store stopovers
Solution Approach 1:
The patent extends the bypass route guidance system to support multiple guidance purposes beyond store stopovers. The route guidance apparatus now handles diverse purposes including sightseeing, dining, and other attractions by integrating purpose information into the route calculation process, making the system universal for various navigation needs
2Adaptability or versatility
If the system provides multiple candidate routes with point calculations based on attraction desirer settings, then users can be guided according to various purposes and preferences, but the system complexity increases due to multiple acquisition units and calculation mechanisms
Solution Approach 1:
The patent combines multiple acquisition units (departure point acquisition, destination acquisition, point resource acquisition, desire information acquisition, non-desire information acquisition) into a unified route guidance apparatus that processes all inputs through a single point calculation unit. This merging approach manages complexity by consolidating functions while maintaining versatility
3Manufacturing precision
If the point calculation unit calculates points for desired and undesired via routes and via points, then users can be effectively guided to preferred locations while avoiding unwanted ones, but the calculation complexity increases
Solution Approach 1:
The patent uses parameter changes by introducing point values that represent attraction desirability. The point calculation unit adjusts route scoring based on desire information and non-desire information parameters, allowing precise route optimization through quantitative parameter manipulation rather than complex structural mechanisms

AI summary
A user guidance system includes a departure point acquisition unit that acquires departure point information, a destination acquisition unit that acquires destination information, a candidate route generation unit that generates a plurality of candidate routes, a point resource acquisition unit that acquires point resource information, a desire information acquisition unit that acquires desire information indicating a via point desired by the attraction desirer, a non-desire information acquisition unit that acquires non-desire information indicating a via point not desired by the attraction desirer, a point calculation unit that calculates a point that is imparted to the candidate route, or a via route or the via point included in the candidate route, and a point providing unit that provides point information indicating the point that is imparted to the candidate route or the via point included in the candidate route to a user.
