Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specific tests are conducted in a laboratory using specialized equipment, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a simplified copy of the laboratory sedimentation test that can be performed at home. The portable device replicates the essential function of measuring erythrocyte sedimentation rate using a small capillary tube and basic optical sensor, eliminating the need for complex laboratory equipment while maintaining diagnostic capability
Solution Approach 2:
The invention uses disposable or simple reusable components such as capillary tubes, basic optical sensors, and microprocessor units that can be manufactured at low cost. These components replace expensive laboratory equipment while providing sufficient functionality for pathology screening
2Measurement precision
If specific tests are conducted in a laboratory, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent divides the blood sample analysis into discrete, rapid measurement steps using a capillary tube format. The sedimentation process is segmented into measurable intervals within the tube, allowing for quick automated reading at specific time points rather than requiring continuous laboratory monitoring
Solution Approach 2:
The invention replaces complex laboratory mechanical and optical systems with a simplified portable device using basic optics and microprocessor control. The automated optical detection system quickly measures sedimentation distance without requiring manual observation or complex laboratory infrastructure
3Loss of time
If non-specific tests are used, then loss of time and cost are reduced, but loss of information increases
Solution Approach 1:
The patent measures the dynamic sedimentation process at multiple time points rather than a single endpoint measurement. By tracking the sedimentation rate changes over time, the system captures more information about blood characteristics, enabling better pathology differentiation while maintaining quick testing
Solution Approach 2:
The device provides immediate automated feedback through the microprocessor and display, comparing measured values against reference ranges to indicate potential pathologies. This instant feedback mechanism compensates for the simplified test design by providing intelligent interpretation that recovers diagnostic information

Function Achieved in This Case
Enables specific and cost-effective analysis of blood samples for pathology identification, reducing the need for extensive laboratory procedures and enabling monitoring of health conditions over time with minimal equipment and expertise.
Implementation Method 1
measuring a rate V at which corpuscular components (1a) contained in the blood sample (1) settle on the bottom of the container (2)
Implementation Method 2
The blood sample is then allowed to sediment, with the test tube set in a predetermined position, in order to be able to measure the rate V at which the corpuscular components (1a) contained in the blood sample (1) settle on the bottom of the container (2)
