Navigation Scenic View Routing Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital mapping systems fail to accurately route users to destinations while ensuring views of specific types of geographical features, such as mountains or waterfalls, along the route.
Innovation Solution
A geographical feature scoring engine assigns categorical scores to road segments or locations based on the extent to which particular types of geographical features can be viewed, using metrics like distance, visibility, size, count, popularity, and diversity, to provide navigation and map data that prioritizes user-specified geographical feature types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the navigation system selects the shortest route to the destination, then the travel time is minimized, but the user cannot guarantee views of specific geographical features along the route
Solution Approach 1:
The patent segments the route into multiple candidate routes, each evaluated for both travel time and geographical feature visibility. The system divides the routing problem into separate evaluations: one for efficiency (time) and one for scenic quality (feature visibility), then combines these evaluations to provide multiple routed options that balance both criteria.
Solution Approach 2:
The patent implements dynamic route selection by providing multiple routed options rather than a single fixed route. The system dynamically evaluates candidate routes based on real-time criteria including travel time and geographical feature visibility, allowing users to select from different route characteristics (fastest vs. most scenic) based on their current preferences.
2Ease of operation
If the navigation system prioritizes routes with views of specific geographical features, then user experience is enhanced, but the route duration increases
Solution Approach 1:
The patent applies partial action by providing multiple routed options with varying degrees of scenic quality rather than forcing users to choose between completely scenic routes (excessive scenic action) or completely efficient routes. The system generates candidate routes with different balances of travel time and feature visibility, allowing users to select the appropriate level of scenic emphasis for their needs.
Solution Approach 2:
The patent changes the evaluation parameters from a single criterion (travel time) to multiple criteria (travel time, geographical feature visibility, route characteristics). By introducing additional parameters for evaluating route quality, the system enables users to optimize for different combinations of parameters based on their preferences, transforming the routing problem from time-only optimization to multi-parameter optimization.
3Measurement precision
If the system evaluates multiple candidate routes based on geographical feature visibility, then route selection accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-identifying and evaluating multiple candidate routes before presenting them to the user. The system performs preliminary calculations of travel time, distance, and geographical feature visibility for each candidate route in advance, so that when users request route options, the computationally intensive evaluation work has already been completed. This reduces the real-time computational burden while maintaining high selection accuracy.
Solution Approach 2:
The patent creates simplified copies or representations of the routing problem for each candidate route evaluation. Rather than performing complex real-time analysis, the system uses pre-computed data structures and models that represent route characteristics, allowing for efficient comparison and selection. The detailed geographical feature data and route attributes are copied into standardized formats that enable rapid evaluation across multiple candidates.

AI summary
To provide navigation directions in response to a request for viewing a particular type of geographical feature on a route to a destination, a computing device receives a request for navigation directions from a starting location to a destination that specifies a particular type of geographical feature for viewing on a route to the destination. The computing device identifies at least one candidate route for navigating to the destination location that includes a road segment from which the particular type of geographical feature can be viewed, and selects a route from the set of candidate routes based at least in part on an extent to which the particular type of geographical feature can be viewed from each candidate route. Then the computing device provides a set of navigation directions for presentation on a client device for navigating to the destination location via the selected route.
