Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual color-based testing is used, then the screening process is simple and accessible, but the measurement precision is subjective and inaccurate
Solution Approach 1:
The patent replaces manual visual color comparison with automated image processing and computer vision algorithms. The system captures images of the test strip using a mobile device camera and uses machine learning models to objectively analyze color changes, substituting human visual assessment with automated digital image analysis to eliminate subjectivity while maintaining accessibility.
Solution Approach 2:
The patent introduces an intermediary layer of image processing software and augmented reality technology between the test strip and the user. This intermediary captures the color data, processes it through trained machine learning models, and presents results in an user-friendly format, bridging the gap between simple testing and accurate measurement.
2Reliability
If specialized electronic readers are used, then the measurement precision is increased and reliability is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent makes the testing system universal by using a mobile device camera that can serve multiple purposes (testing, photography, communication) instead of requiring a dedicated electronic reader. The same device that captures images can also store, process, and share results, eliminating the need for specialized equipment while maintaining reliability through software-based analysis.
Solution Approach 2:
The patent creates a digital copy of the test strip results through image capture, replacing the need for physical electronic readers. The camera captures an optical copy of the color changes, which is then processed digitally, allowing the test results to be stored, analyzed, and transmitted without requiring specialized reading equipment.
3Measurement precision
If clinical visits are required for testing, then the measurement precision and professional oversight are ensured, but the loss of time and accessibility are reduced
Solution Approach 1:
The patent enables self-service testing where individuals can perform the screening at home without requiring clinical visits. The system provides built-in guidance through the mobile application, automatic image capture instructions, and integrated result interpretation, allowing users to independently complete the testing process while maintaining accuracy through automated analysis.
Solution Approach 2:
The patent performs preliminary testing and screening actions at home before potential clinical visits. The system captures test strip images, processes results, and provides preliminary diagnoses that can guide whether further clinical intervention is needed, performing the initial screening function in advance and reducing unnecessary clinic appointments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accessible and cost-effective early detection of chronic diseases through portable and reliable image-based analysis, eliminating the need for clinical visits and providing accurate results.
Implementation Method 1
These tests can include the use of color-based reaction testing, whereby a test pad is exposed to urine, blood, saliva, feces or sweat. Each reagent test pad on the dipstick is chemically treated with a compound that is known to change color in the presence of particular reactants.
Implementation Method 2
a user device having image capturing and processing capabilities configured to capture an image and a processor. The user device is configured to locate, based on the one or more calibration elements, the test matrix in the image, determine if the test matrix indicates the presence of the chronic disease by comparing a detected contrast of the one or more reagents
Data Source
AI summary
A system for diagnostic screening of a chronic disease includes a test matrix and a user device. The test matrix has a calibration surface including one or more calibration elements and one or more reagents. The user device has image capturing and processing capabilities configured to capture an image and a processor configured to locate, based on the plurality of calibration elements, the test matrix in the image, determine if the test matrix indicates the presence of the chronic disease by comparing a detected contrast of the one or more reagents with the test matrix to an augmented reality trained database, and generate a screening report based on the determination.
