Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensor data is continuously transmitted via wireless communication, then the operating state information is always available to users, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by transmitting sensor data only at specific intervals or when changes occur, rather than continuously. The wireless communication interface is activated periodically to send signaling information from the controller to external devices, reducing energy consumption while maintaining information availability.
Solution Approach 2:
The system employs self-service mechanisms where the field bus device autonomously manages its communication activities. The controller determines when signaling information should be transmitted based on predefined criteria, and the wireless interface activates only when necessary, eliminating the need for continuous external control and reducing overall energy usage.
2Ease of operation
If a communication device is integrated in a higher-level bus system, then access to sensor data is provided, but the integration becomes complicated and operational reliability is reduced
Solution Approach 1:
The patent introduces an intermediary wireless communication interface that mediates between the field bus device and external communication devices. This wireless interface acts as a bridge, allowing users to access sensor data without complex integration into higher-level bus systems or physical access to secure areas, thereby simplifying the system architecture while maintaining data accessibility.
Solution Approach 2:
The communication functionality is extracted from the complex higher-level bus system integration and implemented as a separate wireless communication interface within the field bus device. This extraction allows sensor data to be accessed wirelessly without requiring complicated integration with external bus systems, reducing overall system complexity.
3Loss of information
If the wireless communication interface transmits data continuously, then information is always available, but energy is wasted
Solution Approach 1:
The wireless communication interface transmits signaling information periodically or event-driven rather than continuously. The controller generates signaling information based on sensor data and transmits it only when relevant changes occur or at scheduled intervals, ensuring information availability while preventing energy waste from unnecessary continuous transmission.
Solution Approach 2:
The system applies partial action by transmitting only the necessary signaling information derived from sensor data, rather than continuously transmitting all raw sensor data. The controller processes sensor data and transmits only relevant signaling information, reducing energy consumption while maintaining adequate information availability for operational monitoring.

AI summary
A field bus device for detecting an operating state of an automation device includes: a sensor for acquiring sensor data which indicate an operating state of the automation device; a controller configured to generate a signalling information based at least in part on the acquired sensor data; and a wireless communication interface configured to receive a request to transmit the generated signalling information via a wireless communication network and to emit the generated signalling information via the wireless communication network in response to the reception of the request.
