Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current navigation methods fail to flexibly adjust sections of a navigation route due to incomplete information collection or untimely updates, leading to suboptimal routes that do not meet user preferences, thereby reducing user experience.

Innovation Solution

A navigation method that allows users to erase sections of an initial navigation route through a route erasing operation, enabling the electronic device to determine and navigate along a target navigation route based on the modified path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device provides a complete navigation route according to starting point, end point and road information, then the navigation coverage is comprehensive, but the user cannot flexibly adjust suboptimal sections resulting in reduced user experience

Engineering Contradiction:

Improveroute adjustment flexibilityVSAvoidnavigation route optimality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The navigation route is divided into multiple sections that can be independently selected or erased. Users can erase specific route sections they do not want to follow, and the system automatically generates alternative routes for those sections. This segmentation allows flexible user customization while maintaining reliable navigation through automated route recalculation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The navigation route is made dynamic and adjustable during the navigation process. Instead of providing a fixed complete route, the system allows users to modify the route in real-time by erasing unwanted sections, and automatically recalculates alternative routes to maintain navigation reliability while adapting to user preferences.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the electronic device plans navigation routes based on available road information, then the navigation can be provided, but incomplete information collection or untimely updates result in suboptimal routes

Engineering Contradiction:

Improvenavigation route planning efficiencyVSAvoidroute information completeness

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system incorporates user feedback through the route erasing function. When users erase sections they find suboptimal, the system uses this feedback to understand user preferences and automatically generates alternative routes. This feedback mechanism helps improve route quality over time despite incomplete or outdated initial information.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes route parameters dynamically by generating alternative routes when sections are erased. Instead of relying solely on initial route planning with potentially incomplete information, the system adapts by recalculating routes with different parameters (alternative paths, different routing options) to compensate for information deficiencies.

Inventive Principle:

Principle #35Parameter changes

AI summary

A navigation method includes obtaining an initial navigation route, receiving a route erasing operation, and erasing a target section according to the route erasing operation. The target section includes at least a part of the initial navigation route corresponding to the route erasing operation. The method further includes determining a target navigation route according to the initial navigation route and the target section, and controlling an electronic device to perform navigation according to the target navigation route.
