Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large sample sizes are used for direct analysis of viscous samples, then measurement accuracy is improved, but analysis time increases and productivity decreases
Solution Approach 1:
The analysis system is segmented into multiple independent analysis channels (particle counter and ICP-OES) that operate in parallel. Each channel processes a portion of the sample independently, allowing simultaneous measurement of different parameters without requiring sequential analysis of large sample volumes.
Solution Approach 2:
A dilution system with automated sample preparation acts as an intermediary between the viscous sample and the analysis instruments. This intermediary component prepares the sample by diluting it to appropriate concentrations, enabling accurate measurement with smaller effective sample volumes and reducing analysis time.
2Reliability
If large sample sizes are required for analysis, then measurement reliability is improved, but solvent consumption increases
Solution Approach 1:
The measurement process is divided into separate analytical channels that can operate with smaller, optimized sample volumes. The particle counter and ICP-OES each require different but smaller volumes compared to analyzing all parameters in a single large-sample approach.
Solution Approach 2:
The system changes the concentration parameter of the sample through automated dilution, allowing reliable measurements to be obtained with smaller absolute sample volumes. The dilution factor is optimized to provide sufficient analyte concentration for accurate measurement while minimizing total solvent usage.
3Productivity
If samples are diluted prior to analysis, then instrument requirements are reduced and analysis speed improves, but handling complexity increases
Solution Approach 1:
The dilution and sample preparation system is fully automated, performing dilution operations without manual intervention. The system self-regulates sample flow, mixing, and delivery to the analysis instruments, eliminating the need for manual handling while maintaining analysis speed benefits.
Solution Approach 2:
An automated sample preparation station serves as an intermediary that handles all dilution operations. This intermediary device manages the complexity of dilution procedures internally while presenting a simple interface and requiring minimal user interaction.
4Measurement precision
If separate analysis methods are used for particle counting and composition analysis, then measurement precision for each parameter is improved, but system complexity and processing time increase
Solution Approach 1:
The analytical system is divided into specialized segments (particle counter for particle analysis, ICP-OES for elemental composition) that each excel at their specific function. This segmentation allows each instrument to be optimized for its specific measurement type while operating in parallel to reduce overall processing time.
Solution Approach 2:
The integrated system provides multi-functionality by combining particle counting and elemental composition analysis in a single coordinated platform. Both analyses use the same sample introduction system and can process samples simultaneously, reducing overall system complexity compared to completely separate systems.
