Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If rapid diagnostic tests (RDT) are used for malaria detection, then the diagnostic speed and ease of operation are improved, but the reliability and measurement precision deteriorate when parasite density is low or the test is stored for extended periods
Solution Approach 1:
The patent combines the rapid diagnostic test card with a smartphone microscope system. The smartphone camera captures images of the RDT card at high magnification, allowing digital analysis of the test results. This merging allows the system to maintain the speed and ease of RDT while improving reliability through digital image analysis that can detect faint bands that might be missed by visual inspection, especially useful when parasite density is low.
Solution Approach 2:
The smartphone microscope creates digital copies (images) of the RDT card results. These digital images can be analyzed, stored, and reviewed without affecting the original test. The copying process allows for enhanced analysis through image processing algorithms that can detect and measure the test bands more accurately than the human eye, thereby improving reliability while maintaining the rapid nature of the original test.
2Measurement precision
If microscopy with high magnification is used for parasite detection, then the measurement precision and reliability are improved, but the device complexity and ease of operation worsen due to requiring specialized equipment and trained technicians
Solution Approach 1:
The patent makes the smartphone microscope a universal device that can perform multiple functions: it can capture images of RDT cards, analyze blood smears for parasite detection, and potentially serve other diagnostic purposes. By using a smartphone (a ubiquitous device) as the base and attaching simple magnification optics, the system achieves high-magnification microscopy capabilities without requiring specialized microscope equipment. The smartphone's processing power and camera provide the analytical capabilities, while the attached optics provide the magnification, creating a multi-functional diagnostic tool that is both precise and simple.
Solution Approach 2:
The patent introduces a smartphone as an intermediary between the simple RDT card and the need for complex microscopy equipment. The smartphone acts as a mediator that bridges the gap: it captures images of the RDT card or blood smear, provides digital magnification and image enhancement, and uses processing algorithms to analyze the results. This intermediary approach eliminates the need for both complex traditional microscopes and trained technicians while maintaining high measurement precision through digital image analysis.
3Measurement precision
If traditional microscopy methods are used, then the diagnostic accuracy is improved, but the loss of time increases due to manual examination processes
Solution Approach 1:
The smartphone microscope enables continuous rapid examination of multiple samples. Once the device is set up, multiple RDT cards or blood smears can be examined sequentially without repositioning or recalibration. The smartphone's automated image capture and processing capabilities allow for continuous analysis, eliminating the time losses associated with manual microscope adjustment and manual image documentation. The system maintains high diagnostic accuracy while significantly reducing the time required for each examination and for examining multiple samples.
Solution Approach 2:
The patent replaces the manual mechanical examination process with automated digital imaging and processing. Instead of manually adjusting microscope focus, positioning slides, and documenting results, the system uses automated image capture by the smartphone camera, digital magnification, and computer-based image analysis algorithms. This substitution of mechanical manual operations with automated digital processes maintains high diagnostic accuracy while dramatically reducing the time required for examination.
