Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complexity and increased driving risk when manually entering location information from one device to another, such as from a mobile phone to a vehicle's navigation system.
Innovation Solution
A method and apparatus that enables a first intelligent device to display location information and send a message to a second device to output related location information without manual entry, utilizing short-range wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual entry of location information is used, then accuracy of information transfer is improved, but operation complexity increases and driving safety deteriorates
Solution Approach 1:
The patent uses NFC technology to create a contactless copy transfer mechanism. When the mobile phone approaches the vehicle head unit, the location information is automatically copied and transferred without manual entry, eliminating the contradiction between accurate information transfer and operational simplicity
Solution Approach 2:
The system enables self-service operation where the location information transfer is automatically initiated when devices are in proximity. The user simply needs to bring the phone near the head unit, and the system automatically completes the information transfer without requiring manual input or complex operations
2Loss of information
If manual entry of location information is used, then information accuracy is improved, but driving safety deteriorates
Solution Approach 1:
The patent replaces the mechanical manual entry process with an automated NFC-based wireless transfer system. This substitution eliminates the need for drivers to manually input location information, thereby maintaining information accuracy while significantly improving driving safety by removing distracting operations
3Ease of operation
If automatic transfer of location information is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent introduces NFC technology as an intermediary mechanism that enables automatic information transfer. This intermediary layer handles the complexity of wireless communication and data transfer protocols, allowing the user interface to remain simple while the backend system manages the technical complexity of automated transfer

AI summary
This application discloses a geographic information processing method, which may be applied to a terminal like a head unit, an in-vehicle PC, a mobile phone, or a smart band, and may be applied to a scenario in an intelligent vehicle. The method includes: A first device displays first location information on a corresponding first plane, and then the first device sends a first message to a second device. The first message indicates the second device to output location information related to the first location information. After receiving the first message, the second device may output, based on the first message, second location information related to the first location information. This helps simplify a user operation.
