Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If technicians use traditional diagnostic methods for CAN bus issues, then they can identify problems, but the diagnostic process becomes extremely time-consuming and complex
Solution Approach 1:
The system performs preliminary automated diagnostics by connecting to the machine's electronic control modules and executing pre-programmed diagnostic routines that check CAN bus communication, controller responses, and system integrity before the technician begins manual troubleshooting
Solution Approach 2:
A portable diagnostic device serves as an intermediary between the technician and the complex electronic systems, translating machine data into understandable visual representations and guiding the technician through the diagnostic process with step-by-step instructions
2Ease of operation
If technicians travel to remote machine locations for diagnosis, then they can perform hands-on troubleshooting, but machine downtime increases significantly
Solution Approach 1:
The system replaces complex manual mechanical troubleshooting with automated electronic diagnostics that can be performed remotely or on-site using a portable device that communicates digitally with the machine's control modules, eliminating the need for lengthy manual inspection procedures
Solution Approach 2:
The diagnostic system enables technicians to independently troubleshoot and resolve CAN bus issues using the portable device's guided procedures and visual fault location capabilities, reducing dependence on extensive training and specialized knowledge
3Reliability
If internal diagnostic systems are used in machines, then basic issues can be detected, but sophisticated CAN bus problems cannot be diagnosed due to system limitations
Solution Approach 1:
The portable diagnostic device is designed to work with multiple machine types and communication protocols, providing universal diagnostic capabilities that extend far beyond the limited functions of internal systems while maintaining compatibility with existing machine architectures

AI summary
A system and method for diagnosing connection and communication in an industrial machine includes performing a software check to obtain software data related to software applications, performing a connectivity check to obtain connection status data for one or more controllers, and performing a CAN bus check to obtain CAN bus data. The software data, connection status data, and CAN bus data is analyzed to determine a likely cause of an industrial machine connection or communication issue. A solution to the industrial machine connection or communication issue is output to a technician based on the analyzed data.
