Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operator confirmation is used for start and end states, then the system can identify process steps, but the logging precision and reliability deteriorate
Solution Approach 1:
The system automatically detects process step transitions by evaluating sensor data against stored exit rules without requiring operator intervention. The computer unit autonomously determines when process steps begin and end based on sensor parameter values, making the system self-sufficient in logging operations.
Solution Approach 2:
The manual mechanical confirmation process is replaced by an automated electronic evaluation system. The computer unit substitutes human operators by automatically comparing sensor data with exit rules to identify process step transitions, eliminating the need for manual input.
2Reliability
If automated sensor-based transition detection is implemented, then logging reliability improves, but device complexity increases
Solution Approach 1:
The computer unit serves multiple functions: it stores process step definitions, manages sensor data acquisition, evaluates exit rules, and generates logs. This multi-functional approach consolidates complexity into a single device rather than distributing it across multiple specialized components.
Solution Approach 2:
Exit rules and process step definitions are stored in advance in the computer unit before operation begins. This preliminary preparation allows the system to automatically and reliably detect transitions during operation without requiring complex real-time decision-making logic.
3Measurement precision
If multiple sensor parameter values are monitored for exit rules, then process step identification accuracy improves, but the time required for data processing increases
Solution Approach 1:
The computer unit continuously monitors sensor parameter values and continuously evaluates them against stored exit rules without interruption. This continuous evaluation ensures that process step transitions are detected immediately as they occur, minimizing processing delays while maintaining high accuracy through multi-parameter monitoring.

AI summary
The invention relates to a method for carrying out a construction measure, in particular a foundation engineering measure, with a construction device, in particular with a foundation engineering machine, which has a plurality of actuation elements and sensors for recording operating states relating to the actuation elements, and with a computer unit, by which recorded parameter values of the sensors are received when carrying out the construction measure. According to the invention provision is made in that for a construction measure a number of different defined process steps are stored, in that from one defined process step to at least one subsequent defined process step a transition takes place as a result of at least one exit rule, wherein to each exit rule at least one characteristic parameter value of at least one sensor is assigned, and in that the recorded parameter values of the sensors are checked as to the exit rules and, if they occur, a transition from an associated defined process step to a subsequent defined process step is detected.
