Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are used to service various communication protocols, then compatibility with different vehicle systems is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal diagnostic device that can service multiple communication protocols (ISO9141, ISO14230, CAN, etc.) through a single unified interface. The device incorporates protocol identification circuitry that automatically detects and adapts to the appropriate communication protocol, eliminating the need for multiple specialized devices while maintaining full compatibility with different vehicle systems
2Adaptability or versatility
If multiple devices are used to service various communication protocols, then compatibility with different vehicle systems is improved, but cost increases
Solution Approach 1:
The patent merges multiple protocol-specific diagnostic devices into a single integrated unit. The unified device combines protocol identification, adaptation logic, and communication interfaces for ISO9141, ISO14230, CAN, and other protocols into one device, thereby reducing the total cost of servicing equipment while maintaining the ability to service various vehicle systems
3Productivity
If remote reprogramming is enabled, then service efficiency is improved, but communication reliability requirements increase
Solution Approach 1:
The patent implements preliminary connection validation and system readiness checks before initiating remote reprogramming operations. The device verifies communication链路 stability, checks ECU accessibility, and confirms proper protocol handshaking before transferring reprogramming data, thereby ensuring communication reliability while enabling efficient remote service operations

AI summary
Disclosed are methods, systems, and apparatus for remote reprogramming of an automotive controller and determining and reporting vehicle carbon emissions using a local device, a client device, a technician device and a system server. The local device is connected to the automotive controller and is wirelessly connected to the client device. The client device is connected to the technician device through a system server. Programming configurations, including firmware, settings, and parameter updates, are selected from a technician device, sent to the system server, and uploaded to local device using J2534 communication protocol. The client device receives the fuel consumption data from the local device and sends the data to the system server. The system server determines the carbon emissions based on the fuel consumption and reports the emissions to a third-party to certify carbon offset.
