Engineering Contradiction Analysis
1Productivity
If manual data collection and entry is used, then device complexity is reduced, but productivity decreases and human error increases
Solution Approach 1:
A mobile device serves as an intermediary between field operators and control electronics, enabling wireless data collection and configuration. The mobile device includes a user interface for field data input, a processor for data processing, and communication interfaces for wireless transmission to control electronics, eliminating the need for manual keyboard entry in control rooms.
Solution Approach 2:
The patent replaces manual mechanical data entry processes with automated electronic data collection and wireless transmission. Field data is collected through electronic inputs on the mobile device and automatically transmitted to control electronics, substituting the mechanical process of manual keyboard entry with automated digital communication.
2Measurement precision
If manual data entry is used, then device complexity is reduced, but measurement precision decreases due to human error
Solution Approach 1:
The system enables self-service data collection where the mobile device automatically captures field data through electronic inputs without requiring manual transcription. The device processes and transmits data automatically, eliminating human error associated with manual data entry while maintaining simplicity through automated operations.
3Productivity
If on-site data collection is implemented, then productivity improves, but loss of time for data transmission may increase
Solution Approach 1:
The mobile device enables continuous data collection and transmission operations in the field. Data can be collected and transmitted wirelessly in real-time or near-real-time, maintaining continuous operational flow without requiring trips to control rooms or batch processing delays, thus minimizing time loss while maximizing productivity.

AI summary
A mobile device is used in conjunction with control electronics and associated assets and sensors to facilitate the setup or modification of programming in the electronics. The mobile device is used to initially commission sensors by collecting data from the field, such as sensor identity, asset identity and measurement points, and uploading the collected data to the electronics. The mobile device may also be used to select programming in the control electronics for analyzing sensor signals from a particular sensor. The mobile device is also used to collect data from the field for use in linearizing sensor signals when they are received by the control electronics and to transmit maintenance commands to the control electronics thereby causing a programming change in the control electronics to prevent the transmission of a type of command or a type of information, such as a shutdown command or an alarm or alert.
