Solution Overview
Problem
Current medical testing methods for chronic diseases such as diabetes, kidney disease, liver disease, pancreas disease, and urinary tract infections require complex laboratory procedures, are time-consuming, and often necessitate hospital visits, making early detection and self-monitoring difficult and costly.
Innovation Solution
A medical care kit comprising chemical compositions for testing urine glucose, protein, bilirubin, bilinogen, pancreatic amylase, calcium, nitrite, ketone, and pH, allowing for simple, self-administered tests that do not require complicated apparatuses or electrical sources, with indicative spectra for easy interpretation and dynamic record-keeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional laboratory tests with chemical analysis are used, then measurement precision and reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The testing system is segmented into separate functional components: pre-packaged reagent strips containing specific chemical compositions for different analytes, a container for urine sample collection, and a reference chart for result interpretation. Each reagent strip is designed to test for specific substances (glucose, protein, bilirubin, etc.) independently, allowing users to perform multiple tests through simple sequential steps without requiring complex laboratory equipment or procedures.
2Measurement precision
If traditional laboratory tests are used, then measurement precision is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The reagent strips are pre-packaged with all necessary chemical compositions and reagents sealed within the strip structure before use. This preliminary preparation eliminates the need for users to manually prepare solutions, measure reagents, or set up complex testing equipment during the actual testing process. The container is also designed to be ready for immediate sample collection and testing, significantly reducing the time required to perform accurate urine analysis.
3Measurement precision
If traditional laboratory tests are used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system is designed for self-service operation where users can independently collect urine samples using the provided container, apply the sample to pre-packaged reagent strips, and interpret results using the included reference chart. The reagent strips automatically react with urine components to produce visible color changes that indicate the presence and concentration of various substances. This eliminates the need for laboratory technicians, complex equipment operation, or specialized training, making accurate urine testing accessible to ordinary users at home.
4Ease of operation
If self-administered tests are provided, then ease of operation and productivity are improved, but measurement precision may deteriorate
Solution Approach 1:
The reagent strips are designed with controlled chemical compositions and concentrations optimized for direct reaction with urine samples. Each strip contains specific chemicals at predetermined concentrations that produce reliable color changes corresponding to different analyte levels. The container is designed to maintain sample integrity and prevent contamination. These parameter optimizations ensure that even simple user-operated tests yield accurate and reliable results comparable to laboratory methods.
