Solution Overview

Problem

Existing navigation systems fail to accurately capture individualized user preferences and avoid specific prohibited areas, leading to routes that deviate from users' actual needs and preferences.

Innovation Solution

A method and device that receive user-input prohibited areas and generate navigation routes that completely bypass these areas, using touch or voice inputs, and utilize history and real-time data to optimize the route planning process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If navigation systems use advanced algorithms and big data analysis to calculate optimal routes, then route planning efficiency is improved, but the system fails to capture individualized user preferences and avoid specific prohibited areas

Engineering Contradiction:
Improveroute planning efficiencyVSAvoidindividualized user preferences
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by receiving and storing user-defined prohibited areas before route calculation. The navigation system allows users to pre-specify areas they wish to avoid, and this information is stored for subsequent route planning operations, ensuring individualized preferences are incorporated into the algorithm-driven route calculation process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies local quality by allowing users to define specific prohibited areas with precise geographic boundaries. Instead of applying uniform route planning across all areas, the system creates localized restrictions that affect only specific geographic zones, enabling the route calculation algorithm to optimize paths while respecting user-defined local preferences

Inventive Principle:
Principle #3Local quality

2Ease of operation

If navigation systems display routes straightforwardly on navigation map, then user understanding is improved, but the routes deviate from users' actual needs and preferences

Engineering Contradiction:
Improveuser understandingVSAvoidroute accuracy to user needs
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system implements feedback by continuously comparing the generated navigation routes against user-defined prohibited areas and adjusting the route calculation accordingly. The system receives feedback from user preferences, incorporates this feedback into the routing algorithm, and generates routes that both maintain clarity for user understanding and accurately reflect individualized preferences

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of the present disclosure relate to method, device, medium and product for navigation. The method comprises receiving (202) an indication of a prohibited area input by users. The method also comprises generating (204), based on the indication of the prohibited area, a navigation route that is separated from the prohibited area. In this way, the navigation route can be accurately customized, to prevent the navigation route from passing by the areas which the users do not want to enter and ensure that the navigation route is more in line with the actual needs and the preferences of the users, thereby enhancing the user experience of the navigation service.
