Innovation Solution
A communication method utilizing a WEB server that establishes HTML5 Websocket connections between a user's device and a vehicle diagnosis equipment, enabling real-time data interaction and instruction transmission through TCP/IP Socket connections, allowing for remote diagnosis without the need for specific diagnostic apps or platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If near-end diagnosis equipment with specialized diagnosis programs is used, then professional diagnosis capability is achieved, but device complexity and ease of operation deteriorate for ordinary users
Solution Approach 1:
The patent introduces a server as an intermediary between the user's terminal device and the vehicle diagnosis equipment. The server hosts the complex diagnosis programs and processes, while users access them through simple web browsers. This mediator approach allows ordinary users to perform professional-level diagnostics without needing specialized local equipment or software installation.
Solution Approach 2:
The patent replaces the traditional mechanical/software-based diagnosis system (requiring specialized hardware and installed programs) with a web-based system using HTML5 Websocket technology. This substitution eliminates the need for complex local software installations and specialized diagnosis equipment, allowing access through standard web browsers while maintaining professional diagnostic capabilities.
2Ease of operation
If simple data interchange methods are used, then ease of operation is maintained, but real-time performance and data exchange capability deteriorate for complex diagnostics
Solution Approach 1:
The patent changes the communication protocol parameters by implementing HTML5 Websocket connections instead of traditional simple data interchange methods. This allows full-duplex communication with real-time data exchange capabilities while maintaining the simplicity of web-based access. The Websocket protocol enables bidirectional, persistent connections that support complex diagnostic operations requiring real-time feedback.
3Measurement precision
If specialized diagnosis equipment is required, then diagnosis precision is improved, but device complexity and accessibility worsen
Solution Approach 1:
The patent makes the diagnosis system universal by enabling access through standard web browsers on various devices (smartphones, tablets, computers) without requiring specialized diagnosis equipment. The server consolidates the diagnostic functionality, allowing any network-accessible device to perform professional-level vehicle diagnostics while maintaining high diagnosis precision through the sophisticated analysis algorithms running on the server.
