Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used to evaluate blood characteristics, then the evaluation process becomes cumbersome and time-consuming, but the accuracy and speed of coagulation tendency assessment remain insufficient
Solution Approach 1:
The invention utilizes the phase transition of blood from liquid to foam state through controlled aeration. The foaming process transforms blood samples into a stable foam structure that preserves coagulation characteristics while enabling rapid optical measurement. This phase transition allows the system to achieve both high evaluation speed and accurate coagulation tendency assessment by measuring foam stability and structure rather than performing traditional coagulation tests
Solution Approach 2:
The invention replaces complex mechanical and chemical coagulation testing systems with an optical measurement system. By using imaging devices and light scattering analysis to measure foam characteristics, the system eliminates the need for cumbersome mechanical procedures while maintaining or improving measurement precision for coagulation tendency evaluation
2Ease of operation
If simple evaluation methods are used, then the process becomes fast and easy, but the accuracy of blood characteristics assessment is compromised
Solution Approach 1:
The foaming process creates a standardized foam phase from blood samples that inherently preserves coagulation properties. This phase transition provides a simple, uniform measurement medium that can be evaluated through basic optical means while maintaining high accuracy in assessing blood characteristics and coagulation tendency
Solution Approach 2:
The invention changes the measurement parameter from direct blood coagulation observation to foam stability and structural analysis. By measuring foam characteristics such as bubble size distribution, foam height, and drainage rate, the system achieves accurate blood characteristics assessment through simple, standardized optical measurements rather than complex procedural evaluations
