Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable analysis hub integrates multiple components for biomarker analysis, then the capability for point-of-care testing is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple previously separate components (optical sensing, stepper motors, fluid delivery, touchscreen interface, processor) into a single portable analysis hub. This merging of components enables point-of-care testing capability while managing the complexity through unified system architecture.
Solution Approach 2:
The analysis hub is designed as a universal platform capable of performing multiple biomarker analyses through customizable flow protocols and automated bead detection. The system can handle various assay types and biomarkers, making it adaptable to different clinical testing needs.
2Measurement precision
If biomarker testing is performed in far-off labs, then the analysis accuracy is improved, but the time delay for treatment planning increases
Solution Approach 1:
The patent replaces the traditional mechanical/physical transport system (shipping samples to distant labs) with an integrated optical detection and automated analysis system that can perform high-precision biomarker testing locally at the point of care, eliminating transport time while maintaining analysis accuracy.
Solution Approach 2:
The portable analysis hub acts as an intermediary between sample collection and final diagnosis, performing automated bead detection and data processing locally. This intermediary system bridges the gap between simple point-of-care devices and complex laboratory equipment, enabling accurate testing without requiring distant laboratory facilities.
3Reliability
If a standard platform for biomarker approval is established, then the regulatory approval process is improved, but the device complexity and standardization requirements increase
Solution Approach 1:
The patent separates the biomarker analysis system into distinct modular components (assay cards, optical detection module, fluid delivery system, data processing unit) that can be independently validated and approved. This segmentation allows each component to meet specific regulatory requirements while the integrated system provides the standardized platform needed for regulatory approval.

Function Achieved in This Case
Enables rapid, accurate, and reproducible biomarker analysis at the point of care, reducing the need for complex laboratory environments and facilitating the integration of biomarker testing into clinical decision-making.
Implementation Method 1
Once the blood sample and reagents have arrived at the microbeads, a set of biochemical reactions take place which trigger the beads to fluoresce proportionally to the concentration of the biomarker of interest. Digital images of these beads can then be obtained using a simple laboratory-based fluorescence microscope, portable analyzer, or other optical devices
