Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual connection is used for diagnostic systems, then security and authorization control are improved, but time consumption and operational difficulty increase
Solution Approach 1:
The patent replaces the mechanical manual connection process with wireless communication technology. The portable device communicates with the machine through wireless signals, eliminating the need for physical connection while maintaining security through authentication mechanisms. This substitution resolves the contradiction by reducing time consumption without compromising security.
Solution Approach 2:
The system implements automatic authentication and authorization where the portable device automatically verifies its entitlement to access the machine. The agent at the machine automatically processes authentication requests and establishes secure communication channels without manual intervention, enabling self-service operation that reduces time while maintaining security controls.
2Reliability
If manual connection is required for diagnostics, then authorization security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent substitutes manual mechanical connection with wireless communication, making the system easier to operate. The portable device automatically establishes communication with the machine through wireless signals, eliminating the complexity of finding and connecting physical adapters while maintaining secure authorization through authentication protocols.
Solution Approach 2:
The system performs preliminary authentication actions before allowing access. The portable device authenticates its entitlement to access the machine in advance, and the agent at the machine pre-establishes secure communication channels. This preliminary action ensures security is maintained while making operation simpler, as no manual connection is needed during the actual diagnostic process.
3Reliability
If physical connection adaptors are used for various machines, then authorization control is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal wireless communication interface that works across different machine types. Instead of requiring separate physical connection adaptors for each machine type, the portable device uses a single wireless interface to communicate with any machine, maintaining authorization control through authentication mechanisms while significantly reducing device complexity.
Solution Approach 2:
The patent replaces the complex system of machine-specific physical adaptors with a unified wireless communication system. The portable device communicates with different machines through wireless signals, eliminating the need for multiple specialized adaptors and reducing overall system complexity while maintaining secure authorization control.
4Productivity
If network connectivity is added to diagnostic systems, then productivity and remote access are improved, but security risks increase
Solution Approach 1:
The patent implements preliminary authentication actions where the portable device authenticates its entitlement to access the machine before any data transmission occurs. The agent at the machine verifies authentication status and only then establishes secure communication channels for data exchange. This preliminary action enables network connectivity and remote access while maintaining security by ensuring only authorized devices can access the machine.
Solution Approach 2:
The system incorporates feedback mechanisms where the agent at the machine continuously monitors authentication status and communication security. The system provides feedback about authentication state and security status, allowing dynamic control of data transmission. This feedback mechanism enables productivity improvements through network connectivity while managing security risks through continuous monitoring and control.

AI summary
A system and method to troubleshoot a defect in at least one machine is provided. The system includes a portable device having a tracking system to detect when within a threshold proximity of a machine, and a controller to perform the steps of: authenticating the user to operate the portable device and communicating a first signal including the unique identifier of the portable device in response to detecting when within threshold proximity of the at least one machine. The system can further include an agent located at the machine to receive the first signal from the portable device, and in response to automatically verify authorization of the portable device to access the machine; and automatically trigger transmission of an operational data of the least one machine to the portable device over a secure channel.
