Navigation Apparatus Touch Screen Route Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems require complex and troublesome operations to change guide routes, involving multiple steps and tracing of entire roads, making it difficult for users to easily switch to preferred routes due to traffic jams or other conditions.
Innovation Solution
A navigation apparatus that displays traffic jam conditions on a touch screen, allowing users to simply select and change search conditions for specific road sections by tracing on a map, automatically updating the guide route to avoid congested areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the guide route change function is implemented using traditional menu operations, then the system can change guide routes, but the operation becomes complicated and troublesome requiring multiple steps
Solution Approach 1:
The patent replaces traditional mechanical menu-based operations with a graphical touch screen interface. Users can directly touch and drag route sections on the displayed map to modify the guide route, eliminating the need for multiple menu navigation steps and making the route change operation intuitive and simple.
Solution Approach 2:
The patent introduces a visual drag-and-drop interface as an intermediary between the user and the route modification function. By allowing users to directly manipulate route representations on the screen through touching and dragging, the system provides a natural and easy-to-understand interaction method that bridges the gap between user intent and system action.
2Manufacturing precision
If the user traces the entire road to correct a route section, then the route can be corrected, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent divides the route into discrete editable sections that can be independently modified. Instead of requiring users to trace entire roads, the system allows users to select and modify specific route segments by simple touch and drag operations, significantly reducing the time and effort required for route correction while maintaining precision.
Solution Approach 2:
The patent implements partial action by allowing users to modify only the specific portion of the route that needs correction, rather than requiring complete route re-tracing. The drag-and-drop interface enables users to make localized adjustments to route sections, achieving the necessary correction with minimal user input and time investment.
3Reliability
If the system requires thorough tracing of replacement roads, then the new route can be established, but the operation becomes troublesome and complex
Solution Approach 1:
The patent replaces the mechanical tracing operation with a simplified touch-based drag-and-drop interface. Users can establish new routes by visually selecting and dragging between points on the map, eliminating the need for tedious tracing while the system automatically calculates and validates the route, ensuring reliability through automated processing rather than manual precision.

AI summary
A traffic jam guide image showing traffic jam conditions of a plurality of road sections ahead of a current location of a vehicle is displayed together with a map image during a guidance of a guide route from the current location to a destination. Based on a user operation performed on a touch screen, an object road section in which a search condition is to be changed and the search condition in the object road section are set. A second guide route from the current location to the destination is searched for based on the search condition set for the object road section such that the user has only to perform a simple operation through a touch screen to automatically change the search condition and set the road section to which the changed search condition is applied.
