Onboard Instant Messaging System for Seamless Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing onboard communication systems lack the ability to directly transmit and execute information such as addresses and music from instant messaging conversations to onboard devices, requiring users to manually copy and paste text or play music separately.
Innovation Solution
An onboard instant messaging method and system that integrates instant messaging technologies with onboard systems by associating user accounts with vehicles, determining permissions, and exchanging data between user terminals, instant messaging servers, and head units, allowing direct display or execution of messaging data like text, pictures, website links, and audio instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually copy and paste text from instant messaging to onboard navigation system, then address information can be input, but the operation process becomes complex and time-consuming
Solution Approach 1:
The patent introduces an instant messaging server as an intermediary between the user terminal and the head unit. The server receives messaging data containing address information, forwards it to the backend system for processing, and ultimately enables the address to be displayed on the head unit without manual copying. This intermediary mechanism automates the data transfer process, reducing both operational complexity and time consumption.
Solution Approach 2:
The system segments the address transmission process into distinct functional modules: the user terminal for sending messaging data, the instant messaging server for data exchange, the backend system for permission determination and processing, and the head unit for display. This segmentation allows each component to perform its specific function efficiently, eliminating the need for manual intervention in the overall process.
2Adaptability or versatility
If users manually input music information to onboard system, then music can be played, but the process lacks integration and requires separate operations
Solution Approach 1:
The head unit is designed with multi-functionality, capable of displaying messaging data, playing music, and providing navigation services through a single integrated interface. The system can process different types of data (text, audio links, music files) through the same data exchange mechanism, eliminating the need for separate input processes and enhancing system adaptability.
Solution Approach 2:
The patent merges the instant messaging function with the onboard system functions (navigation, music playback) into a unified system. Messaging data containing music information is transmitted through the same channel as address information, and both types of data are processed by the same backend system and displayed on the same head unit, creating an integrated user experience.
3Ease of operation
If direct data transmission from instant messaging to onboard device is implemented, then convenience is improved, but system security and permission control may be compromised
Solution Approach 1:
The backend system performs permission determination before forwarding messaging data to the head unit. The system checks whether the user has the necessary permissions to access certain functions (e.g., navigation, music playback) based on the association relationship stored in the backend system. This preliminary permission check ensures security is maintained while still enabling convenient direct data transmission.
Solution Approach 2:
The system implements a feedback mechanism where the backend system determines permissions based on the association relationship between the user terminal and the head unit, then forwards data only when permissions are granted. The instant messaging server also provides feedback by confirming successful data transmission between components, ensuring both convenience and security through controlled data flow.

AI summary
The invention relates to an onboard instant messaging method and system. The method comprises the steps of: associating an instant messaging user with a vehicle and storing an association relationship in a backend system; sending a permission determination request to an instant messaging server from a user terminal and forwarding the permission determination request to the backend system via the instant messaging server so that the backend system performs permission determination based on the association relationship, and proceeding to a data exchange step described below if the permission determination indicates success, otherwise ending the process; and sending messaging data or a user instruction to the backend system from the user terminal through the instant messaging server, and then forwarding same to a head unit by the backend system. According to the invention, instant messaging can be better integrated with an onboard system, thereby allowing users to uses an instant messaging service on a vehicle more conveniently.
