Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional direct testing methods are used with manual smearing and staining, then staining quality and observation precision are improved, but testing time and operational complexity increase significantly
Solution Approach 1:
The staining reagent is pre-loaded into the micro-cavities of the mesh structural body before the blood sample is applied. This preliminary preparation eliminates the need for manual smearing and subsequent staining steps, allowing the blood cells to be automatically stained upon contact with the pre-positioned reagent, thereby reducing testing time while maintaining staining quality
Solution Approach 2:
The mesh structural body acts as an intermediary carrier that holds the staining reagent in micro-cavities and facilitates its controlled delivery to the blood sample. This intermediary structure enables automatic reagent distribution and staining without requiring manual intervention, reducing both time and operational complexity while preserving measurement precision
2Measurement precision
If conventional direct testing methods with manual operations are used, then direct observation capability is improved, but ease of operation deteriorates due to skilled labor requirements
Solution Approach 1:
The patch performs self-service by automatically delivering the staining reagent from the micro-cavities to the blood sample without requiring manual smearing or staining operations. The mesh structural body's capillary action and controlled release mechanisms enable the system to function autonomously, eliminating the need for skilled labor while maintaining direct observation capability
Solution Approach 2:
The staining reagent is segmented and distributed across multiple micro-cavities within the mesh structural body. This segmentation allows for controlled, localized delivery of the reagent to different regions of the blood sample, enabling automatic staining without manual intervention and improving ease of operation while preserving observation precision
3Measurement precision
If conventional testing procedures are used, then comprehensive blood analysis is achieved, but device complexity and operational steps increase
Solution Approach 1:
The patch combines multiple functions into a single integrated device: the mesh structural body simultaneously serves as the support structure, the reagent reservoir (through micro-cavities), and the reagent delivery mechanism. This merging of functions eliminates multiple separate operational steps while maintaining comprehensive blood analysis capability, thereby reducing device and operational complexity
Solution Approach 2:
The mesh structural body is designed with multi-functionality, serving as both the structural support and the active reagent delivery system through its micro-cavities. This universal design allows a single component to perform multiple roles that would traditionally require separate devices and steps, simplifying the overall system while preserving blood test accuracy
