Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are integrated into the existing monitoring function, then the system structure remains simple, but the ability to perform different evaluations and calculations of working parameters is limited
Solution Approach 1:
The system separates sensor data processing into distinct functional modules: a data acquisition module for recording sensor signals and a computing unit for executing specific algorithms. This segmentation allows different evaluations to be performed independently while maintaining a clear system structure.
Solution Approach 2:
The computing unit is designed to execute multiple different algorithms for calculating various working parameters from the same sensor data. This multi-functionality enables flexible configuration of sensor data recording and adjustment of result data calculation without requiring separate hardware for each evaluation type.
2Measurement precision
If a single monitoring device records sensor data, then the system structure remains simple, but the data processing capability and temporal resolution are insufficient for detailed analysis
Solution Approach 1:
The system divides data processing into two separate pathways: a monitoring device for basic monitoring at lower sampling rates and a computing unit with a data acquisition module for detailed analysis at high sampling rates. This segmentation provides both sufficient monitoring capability and high-resolution data analysis without overwhelming system complexity.
Solution Approach 2:
The system implements differentiated sampling rates where the monitoring device uses a lower sampling rate sufficient for basic monitoring, while the data acquisition module uses a higher sampling rate for detailed analysis. This partial action approach optimizes resource usage by applying excessive measurement precision only where needed.
3Loss of information
If all sensor data are processed and stored with high temporal resolution, then complete analysis capability is achieved, but data storage requirements and processing load increase significantly
Solution Approach 1:
The system segments data processing by function and resolution requirement: the monitoring device handles basic monitoring with lower data volume, while the computing unit processes only the necessary high-resolution data for specific algorithm executions. This segmentation maintains data completeness for analysis while significantly reducing overall data storage requirements.
Solution Approach 2:
The system applies different data processing quality levels to different purposes: high temporal resolution is applied only where needed for detailed algorithm analysis, while lower resolution suffices for general monitoring. This local quality approach optimizes the balance between data completeness and storage requirements.

AI summary
A system for working on a track with a track maintenance machine has a machine controller and a work unit controlled thereby, with sensors being arranged to monitor the work unit. In this context, the sensors are coupled to a data acquisition module for the separate recording of sensor data, with the data acquisition module being connected to a computing unit in which a first algorithm for calculating result data from the sensor data is set up. In this way, the system contains additional structural components for processing sensor signals. With the data acquisition module and the computing unit, different evaluations of the working mode can be performed independently of an existing monitoring function.
