Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a general-purpose flow cytometer is used to measure blood preparations, then measurement capability is achieved, but operator workload increases due to cumbersome manual procedures for specimen preparation and detector settings
Solution Approach 1:
The blood preparation measurement device automatically performs specimen preparation and detector setting based on the measured object type, eliminating the need for operator intervention in these steps. The system self-adjusts measurement parameters and automatically prepares specimens by mixing with appropriate reagents, making the device serve itself rather than requiring continuous operator management.
Solution Approach 2:
The device automatically changes measurement parameters such as detector sensitivity, blood cell fractionation methods, and specimen preparation protocols based on the selected blood preparation type. This dynamic parameter adjustment resolves the contradiction by adapting the system configuration to match the measurement target, thereby simplifying operation while maintaining measurement accuracy.
2Productivity
If manual specimen preparation is performed for each measurement item, then measurement accuracy is maintained, but time consumption and reagent usage increase
Solution Approach 1:
The device merges multiple measurement item preparations into a single automated process. Instead of preparing specimens separately for each measurement item, the system combines specimen preparation, reagent mixing, and measurement execution into one integrated automated workflow, significantly improving productivity while reducing preparation time.
Solution Approach 2:
The system performs preliminary actions by pre-configuring measurement parameters and automatically preparing specimens before actual measurement begins. The device anticipates the measurement needs based on the selected blood preparation type and completes all preparatory steps automatically, eliminating time-consuming manual procedures.
3Measurement precision
If individual detector settings are made for each measurement, then measurement precision is achieved, but operational complexity increases
Solution Approach 1:
The device automatically adjusts detector sensitivity and measurement parameters based on the selected blood preparation type, eliminating the need for operators to manually configure each detector setting. The system self-optimizes measurement conditions while maintaining precision, thereby simplifying operation.
Solution Approach 2:
The system automatically changes detector parameters such as sensitivity levels and measurement thresholds based on the measured object type. This automated parameter adaptation maintains measurement precision while eliminating complex manual setting procedures.
