Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional temperature and pressure sensors are provided at the site of gas analysis, then measurement precision is improved, but device complexity and installation costs increase due to required welding of additional flanges
Solution Approach 1:
The temperature and pressure sensors are integrated within the existing optoelectronic measurement rod structure. The sensors are nested inside the hollow measurement rod, utilizing the existing structural space rather than adding external components. This eliminates the need for additional flanges and welding operations while maintaining precise measurement capability at the gas analysis site.
Solution Approach 2:
The measurement rod is designed to serve multiple functions simultaneously: it acts as both the optical measurement path for gas concentration analysis and the housing for temperature and pressure sensors. This multi-functional design consolidates what would otherwise be separate measurement systems into a single integrated unit, reducing installation complexity while improving overall measurement precision.
2Ease of manufacture
If additional flanges and access points are added to the gas line, then sensor installation is enabled, but installation costs and operational disruption increase
Solution Approach 1:
The temperature and pressure measurement capabilities are merged with the existing optoelectronic measurement rod. By combining multiple sensing functions into a single device that already requires installation in the gas line, the invention eliminates the need for additional access points, flanges, and welding operations. The single measurement rod installation maintains plant operational efficiency while enabling comprehensive gas analysis.
3Device complexity
If optical measuring process is used to determine temperature and pressure, then device complexity is reduced, but measurement precision is insufficient except at very high temperatures
Solution Approach 1:
The measurement system is segmented into distinct functional components: the optoelectronic apparatus for optical measurement and separate temperature and pressure sensors for physical quantity measurement. This segmentation allows each component to perform its specialized function optimally - the optical system for gas concentration and the dedicated sensors for accurate temperature and pressure detection across various conditions, not just high temperatures.
