Engineering Contradiction Analysis
1Loss of information
If traditional methods (fragmented colored laminates, quantum dot loaded polymer beads, rare-earth doped glass microbarcodes) are used to produce encoded microparticles, then codespace and identification capability are improved, but manufacturing cost and process complexity increase significantly
Solution Approach 1:
The microparticle is divided into multiple distinct segments (e.g., 2-10 segments) along its length, with each segment having different optical properties (reflectivity, absorption, fluorescence). This segmentation enables high codespace through various segment arrangements while using simple spherical geometry and standard materials, reducing manufacturing complexity compared to traditional barcode methods
Solution Approach 2:
Different regions (segments) of the microparticle are assigned different local properties (optical characteristics such as reflectivity, absorption, or fluorescence). This allows encoding information through spatial arrangement of properties rather than requiring complex overall particle structures, simplifying the manufacturing process while maintaining high codespace capacity
2Loss of information
If traditional encoded microparticles are used, then identification capability is improved, but reliability and precision in detection are insufficient
Solution Approach 1:
The invention uses segments with different optical properties including variations in color, reflectivity, absorption, and fluorescence characteristics. These optical differences enable reliable and precise detection of microparticle codes through standard optical detection systems, improving detection reliability while maintaining high identification capability
Solution Approach 2:
The invention transitions from 2D surface barcodes to 3D spherical particles with segments arranged along the diameter. This dimensional change allows encoding in multiple spatial dimensions (position, orientation, optical property type), enhancing both identification capability and detection reliability through more robust optical signatures
3Measurement precision
If complex preprocessing procedures are used for traditional encoded microparticles, then detection accuracy is improved, but ease of operation and manufacturing flexibility deteriorate
Solution Approach 1:
The microparticles are designed with inherent optical contrast through segments of different optical properties, enabling them to be directly detected by standard optical systems without requiring complex preprocessing steps. The particles self-differentiate through their intrinsic optical characteristics, eliminating the need for additional labeling or preparation procedures
Solution Approach 2:
The segmented spherical design with varied optical properties creates a universal detection platform that works with multiple detection modalities (reflectivity-based, absorption-based, fluorescence-based systems). This multi-functionality allows a single particle design to achieve high detection accuracy across different assay types without requiring method-specific preprocessing
