Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional process gas chromatographs use discrete plumbing, then they can perform analyses, but they have an intrinsically large footprint resulting in complex and costly setups
Solution Approach 1:
The system divides the gas chromatograph into modular analytical modules that can be independently configured and connected to a shared manifold plate, allowing each module to be optimized for specific applications while using common infrastructure
Solution Approach 2:
The manifold plate serves as a universal interface that supports multiple analytical modules with different requirements, providing common sample introduction and carrier gas delivery while enabling diverse analysis types simultaneously
2Ease of repair
If gas chromatographs have multiple access points for maintenance, then servicing can be performed, but mounting for easy servicing becomes difficult and requires extra plant space
Solution Approach 1:
The system separates maintenance access into module-level interfaces that can be serviced independently from the main enclosure, allowing technical personnel to access and service individual modules without needing to disassemble the entire instrument or require excessive external access points
3Productivity
If existing compact gas chromatographs perform two analyses on the same sample gas stream, then they share timing for sample injection and measurement, but they are not independent and the faster analysis is limited by the slower one
Solution Approach 1:
The system divides the analysis process into independent modules, each with its own timing control and sample handling, allowing simultaneous independent analyses without mutual interference
Solution Approach 2:
Each analytical module operates with dynamic, independent timing control that can be optimized for its specific analysis requirements, allowing flexible scheduling and execution of multiple analyses without being constrained by the slowest module
4Ease of manufacture
If gas chromatographs have fixed plumbing and software, then they are easier to manufacture, but they limit adaptability to different application needs
Solution Approach 1:
The system separates the common infrastructure (manifold plate, carrier gas delivery) from the application-specific components (analytical modules), allowing the common parts to be manufactured once and reused while enabling flexible configuration for different applications
Solution Approach 2:
The manifold plate and shared infrastructure serve multiple functions across different analytical modules, providing a universal platform that can be manufactured once and adapted to support various analysis types through module substitution
