Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple detection units with different analytical detectors are used to perform various tests, then the analytical options and test versatility are increased, but the complexity of accurately supplying various reagents to each detection unit increases
Solution Approach 1:
The fluid storage system is divided into multiple separately keyed compartments, each dedicated to storing a specific reagent or fluid type. This segmentation allows each compartment to be independently managed and supplied to specific detection units, reducing the complexity of managing a single complex supply system for multiple detectors.
Solution Approach 2:
Each compartment is equipped with a unique physical key pattern that is asymmetric and specific to that compartment. This asymmetric keying system ensures that only the correct compartment can be installed in its designated location, preventing incorrect reagent installation and simplifying the operator's task of ensuring proper reagent placement in a multi-detection unit system.
2Reliability
If physically keyed compartments are used to prevent incorrect fluid installation, then the reliability of reagent supply is improved, but the device complexity increases
Solution Approach 1:
Each compartment features a unique asymmetric physical key pattern that must match its corresponding slot. This simple yet effective asymmetric design ensures that only the correct compartment can be physically installed in the correct location, providing high reliability with minimal structural complexity.
Solution Approach 2:
The physical keying system provides automatic self-checking functionality. When an operator attempts to install a compartment, the key pattern automatically verifies compatibility with the slot, eliminating the need for additional verification steps or complex control systems to ensure correct reagent installation.
3Productivity
If barcoding and fluid counters are implemented to track reagent levels, then the productivity and operational efficiency are improved, but the device complexity increases
Solution Approach 1:
Each compartment is pre-labeled with a barcode containing identification information before installation. This preliminary action allows the system to automatically identify and track each reagent compartment upon installation, enabling efficient inventory management and reducing operational complexity through automated data capture.
Solution Approach 2:
Fluid counters are implemented to continuously monitor and provide feedback on reagent levels in each compartment. This feedback mechanism allows the system to automatically track consumption, alert operators when reagents are low, and manage inventory efficiently, improving productivity through automated monitoring rather than manual checking.
