Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for vehicles do not adequately consider user preferences and capabilities when analyzing potential routes, particularly in terms of difficulty, traffic, speed, and road conditions, which may lead to unsuitable route selections.
Innovation Solution
A method and system that utilize a processor to analyze potential routes based on measures of difficulty, including lane changes, traffic and speed conditions, and road surface conditions, and allow users to input a desired tolerance for difficulty level, enabling the selection of routes that align with their preferences and vehicle capabilities.

Engineering Contradiction Analysis
1Ease of operation
If navigation systems analyze routes based only on time and distance, then route selection is simple and quick, but user preferences and capabilities are not adequately considered
Solution Approach 1:
The navigation system dynamically adjusts route evaluation criteria based on user-defined difficulty tolerance levels. The system transitions from static time/distance-based routing to dynamic multi-factor routing that adapts to individual user capabilities and preferences, allowing the same destination to yield different route recommendations for different users or the same user under different conditions.
Solution Approach 2:
The system introduces multiple new parameters beyond time and distance, including difficulty measures based on lane changes, traffic conditions, speed variations, and road surface conditions. Users can adjust the weight of these parameters through difficulty tolerance settings, enabling flexible adaptation of route selection to match user preferences and vehicle capabilities.
2Measurement precision
If navigation systems incorporate multiple factors including difficulty, traffic, speed, and road conditions, then route selection accuracy improves, but system complexity increases
Solution Approach 1:
The complex route evaluation process is segmented into distinct components: difficulty measurement (lane changes, turns), traffic condition assessment, speed condition analysis, and road surface condition evaluation. Each component is calculated separately and then integrated through the difficulty tolerance parameter, making the system manageable and allowing selective optimization of individual components.
Solution Approach 2:
The difficulty tolerance parameter serves as an intermediary that synthesizes multiple complex factors into a single user-friendly input. This mediator allows users to control the influence of various route characteristics without directly managing each parameter, simplifying the user interface while maintaining comprehensive route analysis capability.
3Measurement precision
If the system calculates difficulty measures based on lane changes, traffic, speed, and road conditions, then route difficulty assessment accuracy improves, but computational requirements increase
Solution Approach 1:
The system calculates difficulty measures for multiple potential routes in parallel, computing lane change requirements, traffic conditions, speed variations, and road surface conditions for each route. By performing these calculations for all candidate routes simultaneously rather than sequentially evaluating one route at a time, the system achieves comprehensive assessment while optimizing computational efficiency through parallel processing.
