Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If emission data is aggregated from multiple sources, then comprehensive emission monitoring is achieved, but data traceability and verification become more difficult
Solution Approach 1:
The system segments emission data by source type (e.g., combustion sources, process emissions, fugitive emissions) and maintains separate calculation chains for each segment. This allows comprehensive aggregation while preserving traceability to individual sources through structured data organization and source-specific metadata.
Solution Approach 2:
The system introduces an intermediary data structure that links aggregated emission data back to original sensor readings and calculation methods. This intermediary layer maintains verification pathways without preventing data aggregation, enabling both comprehensive monitoring and source-level traceability.
2Measurement precision
If detailed emission calculations are performed, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts calculation detail based on source characteristics and regulatory requirements. Different emission sources receive appropriately detailed calculation methods (e.g., mass balance for process emissions, stack testing for combustion sources), avoiding unnecessary complexity while maintaining required precision.
Solution Approach 2:
The system changes calculation parameters based on data availability and source type. It selects from multiple calculation methods (emission factors, mass balance, direct measurement) and adjusts input parameters dynamically, achieving high precision where needed while simplifying calculations for sources with limited data.
3Reliability
If uncertainty analysis is included, then measurement reliability is improved, but data processing time increases
Solution Approach 1:
The system performs uncertainty analysis preliminarily during data collection and initial processing. By calculating uncertainty components as data is gathered rather than performing comprehensive uncertainty analysis on final aggregated data, the system improves reliability without proportionally increasing total processing time.

AI summary
A method for display emission data associated with a site device includes obtaining sensor data from at least one sensor associated with the site device, determining, based on the sensor data, emission data corresponding to emissions associated with the site device over a period of time using one or more emission systems, generating display data corresponding to the emission data and traceable relationships between the emission data and the sensor data, and operating a display device to provide the display data to a user.
