Server-Based Vehicle Diagnosis Software Authorization and Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle diagnosis devices are bundled with software for all brands by default, leading to increased costs and inefficiencies as maintenance technicians often only diagnose faults for specific vehicle types, limiting flexibility and autonomy in software configuration.
Innovation Solution
A method and system that utilize a server to manage software authorizations based on user identity and vehicle type, allowing users to acquire and configure only the necessary software for specific vehicle types, reducing the need for full software bundles and enabling flexible software configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle diagnosis devices are bundled with software for all brands by default, then users can diagnose any vehicle type, but the cost of the diagnosis device and maintenance increases
Solution Approach 1:
The patent segments the software functionality by vehicle type, dividing the monolithic software bundle into separate software modules for different vehicle types (e.g., domestic vehicles, foreign vehicles, new energy vehicles). Users only need to download and install the software modules corresponding to the vehicle types they actually diagnose, rather than paying for all vehicle types. This segmentation resolves the contradiction by maintaining versatility through modular availability while reducing cost through selective installation.
Solution Approach 2:
The patent implements dynamic software configuration where the software bundle is not fixed but can be dynamically adjusted based on user needs and actual diagnosis requirements. The system allows users to flexibly add or remove software modules for different vehicle types as needed, transforming the static all-inclusive software model into a dynamic, on-demand software selection model that adapts to specific usage scenarios.
2Adaptability or versatility
If vehicle diagnosis devices include all software functions by default, then users have complete diagnostic capability, but the device complexity and software configuration burden increases
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically identifies the user's actual diagnostic needs and configures the appropriate software bundle without requiring manual selection. The server automatically determines which software modules should be included based on the diagnosis requests and user profile, then configures and delivers the optimized software package. This self-service approach resolves the contradiction by providing complete diagnostic capability when needed while eliminating the complexity of manual software configuration.
3Adaptability or versatility
If users purchase full software bundles, then all vehicle types can be diagnosed, but the cost-effectiveness and resource utilization decreases
Solution Approach 1:
The patent applies partial action by providing users with exactly the software coverage they need rather than the complete set for all vehicle types. The system analyzes actual diagnosis requirements and provides a partial software bundle that covers only the relevant vehicle types, eliminating payment for unnecessary vehicle type coverage. This resolves the contradiction by maintaining adequate versatility for actual needs while significantly improving cost-effectiveness through reduced software licensing costs.

AI summary
A method, a system, and a device for diagnosing a vehicle, and a server. The method is applied to a server and includes: receiving vehicle diagnosis request information sent by a vehicle diagnosis device, where the vehicle diagnosis request information includes identity information of a user and a vehicle type; determining whether the user has an authorization of vehicle diagnosis software corresponding to the vehicle type, based on the identity information of the user; returning authorization information, for the vehicle diagnosis device to diagnose a to-be-diagnosed vehicle, if it is determined that the user has the authorization; and returning prompt information to prompt the user to acquire the authorization of the vehicle diagnosis software corresponding to the vehicle type and then to diagnose the to-be-diagnosed vehicle, if it is determined that the user does not have the authorization.
