Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data from mobile and stationary gas measuring devices are analyzed separately, then device complexity is reduced, but measurement precision and reliability deteriorate due to missed synergies and inability to perform cross-validation
Solution Approach 1:
The patent combines data from mobile gas measuring devices (worn by workers) and stationary gas measuring devices (fixed at locations) into a unified data analysis system. The central evaluation unit processes both data streams together, enabling cross-validation of measurements and synergistic analysis that improves measurement precision while maintaining manageable system complexity through integrated architecture
2Reliability
If joint data analysis is implemented, then reliability and error detection improve, but data processing time and computational requirements increase
Solution Approach 1:
The system performs preliminary actions by continuously processing and evaluating data in real-time as it is generated. The central evaluation unit continuously compares measurements from mobile and stationary devices, enabling immediate error detection and reliability validation without requiring batch processing or delayed analysis, thus minimizing data processing time while maintaining high reliability
3Reliability
If mobile gas measuring devices are used for personal protection, then worker safety is improved, but data availability for joint analysis is reduced due to limited transmission capabilities
Solution Approach 1:
The mobile gas measuring devices are designed with multi-functionality: they serve both personal protection functions (real-time alarm to worn workers) and data collection functions (transmitting measurements to central evaluation). This universal design ensures that the same device supports both safety monitoring and joint data analysis without compromising either function, maintaining data availability while improving worker safety

AI summary
A process and a system analyze data of at least one mobile gas measuring device as well as of a stationary gas measuring device (3a, 3b). Data are generated by the mobile gas measuring device and by the stationary gas measuring device (3a, 3b) as a function of a gas concentration and are transmitted to a central data processing unit (1). Further, the data are supplemented with information in relation to a location of the data generation before, during or after the transmission. The processed data of the mobile gas measuring device and of the stationary gas measuring device (3a, 3b) are sent to a data analysis unit (2), in which a joint analysis of the processed data of the mobile gas measuring device and of the stationary gas measuring device (3a, 3b) is carried out for generating at least one result value.
