Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If maintenance is performed on-site by local operators, then response time and service availability are improved, but maintenance quality and effectiveness deteriorate due to lack of operator expertise
Solution Approach 1:
The portable electronic device acts as an intermediary between the non-expert operator and the service center experts. It captures alarm signals from the electromechanical device, transmits them to remote experts via wireless communication, and receives back guided maintenance instructions. This mediator enables non-expert operators to perform expert-level diagnostics and maintenance tasks on-site without needing deep technical knowledge, thus improving response time while maintaining high maintenance quality.
Solution Approach 2:
The system implements a feedback loop where alarm signals from the electromechanical device are continuously monitored and transmitted to remote experts. The experts analyze these signals in real-time and provide feedback in the form of guided maintenance operations. The operator executes these operations and the results are fed back to the experts, who adjust their guidance accordingly. This continuous feedback mechanism ensures high maintenance quality even when performed by non-expert operators in remote locations.
2Productivity
If complex maintenance operations are performed on-site, then service speed is improved, but operational complexity increases due to need for expert knowledge and tools
Solution Approach 1:
The maintenance operation is segmented into distinct phases: alarm detection, signal transmission to service center, receipt of guided operations, and execution of maintenance tasks. The portable electronic device handles the complex signal processing and expert communication, while the operator focuses on executing straightforward physical maintenance tasks. This segmentation allows complex maintenance to be performed quickly on-site while the complexity is managed by the automated system rather than the operator.
Solution Approach 2:
The system enables self-service maintenance by providing automated alarm monitoring and transmission, along with expert-guided instructions. The portable device automatically performs signal capture, analysis, and communication with the service center, reducing the burden on the operator. Operators can independently perform maintenance operations using the guided instructions without requiring expert knowledge or complex toolkits, thus improving service speed while managing operational complexity.
3Reliability
If service center support is provided remotely via video conferencing, then expert knowledge becomes accessible, but service time and coordination complexity increase
Solution Approach 1:
The system replaces the mechanical video conferencing approach with an automated electronic communication system. Instead of setting up complex video calls and coordinating schedules, the portable device automatically transmits alarm signals and receives maintenance instructions through wireless communication protocols. This substitution of automated electronic communication for manual video conferencing provides equal access to expert knowledge while dramatically reducing service time and coordination complexity.

AI summary
A maintenance method of an electromechanical device comprises the steps of: - making available to a control unit of the electromechanical device data communication means based on a wireless communication protocol; - providing an operator a portable electronic device suitable to implement augmented reality and having a database in which is stored a list of maintenance operations that can be performed on the electromechanical device, - activating data communication between the electronic control unit and the portable electronic device and transferring from the first to the second the status signals and/or possible alarm signals; - in the presence of at least one alarm signal, correlating said alarm signal with at least one maintenance operation and communicating to the operator, thanks to augmented reality, the alarm signal and the maintenance operations related to said alarm signal.
