Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gas quality measurement devices are used with separate sampling, pressure reduction, and measuring components, then the measurement function is achieved, but the space requirement and device complexity increase significantly
Solution Approach 1:
The patent combines the sampling device, pressure reducing device, and measuring device into a single integrated measuring device. The sampling device includes a sampling probe connected via a line to a pressure reducing device, which is in turn connected to a measuring device, all within one unit. This integration eliminates the need for separate peripheral equipment and reduces overall system complexity while maintaining measurement reliability.
Solution Approach 2:
The integrated measuring device serves multiple functions simultaneously: it samples gas from the gas line, reduces the pressure of the sampled gas, and measures the gas quality. This multi-functionality is achieved within a single device structure, eliminating the need for multiple separate components and reducing installation space requirements.
2Reliability
If conventional installations with separate components are used, then the measurement capability is provided, but the investment costs and space requirements increase
Solution Approach 1:
The patent integrates the sampling device, pressure reducing device, and measuring device into a single compact unit. The sampling probe, connection line, pressure reducing device, and measuring device are all housed within one integrated structure, significantly reducing the space required for installation compared to conventional separate-component installations.
Solution Approach 2:
The patent employs a nested structure where the line connecting the sampling probe to the pressure reducing device is arranged internally within the integrated measuring device. This nesting minimizes external connections and reduces the overall footprint of the installation, allowing for compact mounting in limited spaces.
3Reliability
If conventional setups with large dead volumes are used, then the measurement function is achieved, but gas emissions increase significantly
Solution Approach 1:
The integrated design minimizes dead volume by combining all necessary components (sampling probe, line, pressure reducing device, measuring device) into a compact unit with short internal connections. This reduces the amount of gas that needs to be handled and minimizes emissions compared to conventional setups with extensive external piping and larger component volumes.
Solution Approach 2:
The pressure reducing device is integrated directly into the sampling line before the gas enters the measuring device. This preliminary pressure reduction within the integrated structure minimizes the volume of gas that needs to be transported and measured, thereby reducing emissions associated with gas handling in the measurement system.
4Reliability
If conventional installations with extensive peripheral equipment are used, then the measurement capability is provided, but the assembly effort and installation time increase
Solution Approach 1:
The patent integrates the sampling device, pressure reducing device, and measuring device into a single pre-assembled unit. This integration eliminates the need for complex on-site assembly of multiple separate components, significantly reducing installation time and effort while maintaining full measurement capability.
Solution Approach 2:
The integrated measuring device is designed to be pre-assembled and pre-tested as a complete unit before installation. The sampling probe, connection line, pressure reducing device, and measuring device are all configured and connected in advance, allowing for rapid installation by simply mounting the complete integrated unit at the desired location.
