Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote diagnostic systems are used to access diagnostic software applications over the internet, then repair facilities can service multiple vehicle makes and models without local installations, but data transmission reliability deteriorates due to varying internet connectivity and latency
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting data transmission parameters (such as protocol selection, data packet size, timeout values, and compression levels) based on detected internet connectivity conditions and latency measurements. This allows the system to maintain reliable communication over varying internet connections while supporting multiple vehicle makes and models through the same remote diagnostic infrastructure.
2Measurement precision
If diagnostic data transmission parameters are customized for each vehicle configuration, then communication accuracy improves, but system complexity increases due to multiple configuration options
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple connectivity profiles with optimized transmission parameters for different vehicle types, makes, and models. When a diagnostic session is initiated, the system automatically selects and applies the appropriate pre-configured profile based on vehicle identification, eliminating the need for manual configuration and reducing system complexity while maintaining high transmission accuracy.
3Reliability
If manual configuration of diagnostic parameters is performed for each connection, then communication reliability improves, but time consumption increases during diagnostic sessions
Solution Approach 1:
The patent applies self-service by implementing automatic detection and selection of appropriate connectivity profiles based on vehicle identification information and internet connection characteristics. The system autonomously configures transmission parameters without requiring manual intervention from technicians, thereby maintaining communication reliability through optimized parameter selection while eliminating the time loss associated with manual configuration.
4Device complexity
If standardized transmission parameters are used for all remote diagnostic connections, then system simplicity is maintained, but adaptability to different vehicle makes and models deteriorates
Solution Approach 1:
The patent applies universality by creating a multi-functional connectivity profile system where a single standardized framework supports multiple vehicle makes, models, and communication protocols. The system maintains simplicity through a unified profile structure while achieving broad adaptability by incorporating vehicle-specific parameter sets within the universal framework, allowing one system to serve multiple diagnostic requirements.

AI summary
A system and method of establishing remote diagnostic data communications between a local diagnostic computer system and a remote diagnostic computer system comprising connecting a local vehicle diagnostic computer system at a repair facility to a vehicle at the repair facility to be in communication with an electronic system of the vehicle, initiating a connection between the local vehicle diagnostic computer system and a remote diagnostic computer system, where the remote diagnostic computer system is located remotely from the repair facility and comprises a diagnostic application program for use with the electronic system of the vehicle, and selecting a remote data connectivity profile based on one or more data connectivity factors with the remote data connectivity profile being operable to set diagnostic data transmission parameters between the remote and local vehicle diagnostic computer systems whereby diagnostic data is then communicated based on the remote data connectivity profile.
