Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual triggering of clock signal is used for synchronization, then the measuring amplifier can be adapted to sensors without technically qualified knowledge, but manual operation leads to malfunctions and incorrect measurement results
Solution Approach 1:
The measuring amplifier automatically detects sensor connection through the plug connection contacts and triggers the clock signal itself without requiring manual intervention. The system serves itself by automatically recognizing when a sensor is connected and initiating the synchronization process, thereby maintaining ease of operation while eliminating manual errors that compromise reliability.
Solution Approach 2:
The measuring amplifier continuously monitors the connection state of the sensor through the plug connection contacts. When a sensor is detected, the system provides feedback by automatically triggering the clock signal to synchronize with the sensor's data transmission, ensuring reliable adaptation without manual intervention.
2Ease of operation
If manual triggering of clock signal is used, then no technical knowledge is required for adaptation, but the measuring amplifier may continue with previous settings instead of reading new sensor data
Solution Approach 1:
The measuring amplifier automatically detects sensor connection and initiates the data reading process without requiring manual knowledge or intervention. The system self-manages the entire adaptation process, ensuring that new sensor characteristic data is always read and processed, preventing information loss about sensor properties.
Solution Approach 2:
The measuring amplifier is pre-programmed to automatically detect sensor connection through the plug connection and trigger the clock signal before the user needs to take any action. This preliminary automatic action ensures that sensor data is read and processed immediately upon connection, preventing loss of characteristic information.
3Measurement precision
If automatic detection of sensor connection is implemented, then measurement accuracy is improved, but device complexity increases due to additional detection circuitry
Solution Approach 1:
The plug connection contacts serve multiple functions: they provide both the electrical connection for sensor operation and the detection function for automatic recognition. By making the connection contacts multi-functional, the system achieves automatic detection without adding separate detection circuitry, thus improving measurement precision while minimizing the increase in device complexity.

AI summary
The method involves providing a plug (5) comprising a contact pair (7) with a contact (8) and another contact (9) coupled with the former contact. Contacts (12, 13) of a measurement amplifier (4) contact with the contacts (8, 9), and an electrical potential is applied to the contact (8) by the amplifier. Electrical potential to the contact (9) of the contact pair is measured by the amplifier, and the electrical potentials of both the contacts of the contact pair are compared by the measuring amplifier.
