Problem
Current COVID-19 detection methods suffer from inaccuracy, which can lead to serious consequences, necessitating an improvement in detection accuracy.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the treatment liquid flows into the outer cylinder through the inner side wall of the inner cylinder, then the treatment liquid can react with the virus, but leakage may occur at the connection part between the inner cylinder and outer cylinder, causing pollution of the test strip
Solution Approach 1:
The inner cylinder is nested within the outer cylinder, with the inner cylinder positioned inside the outer cylinder such that treatment liquid flows from the inner cylinder through its side wall into the outer cylinder. This nested configuration contains the treatment liquid within a defined inner chamber during the reaction phase, preventing premature leakage while allowing controlled flow into the outer cylinder for subsequent test strip contact.
Solution Approach 2:
The device is segmented into distinct functional zones: an inner cylinder for initial virus-treatment liquid reaction, an outer cylinder for housing the test strip and receiving the virus-adsorbed treatment liquid, and a mounting cover with liquid supply assembly. This segmentation isolates the treatment liquid during critical reaction phases, preventing leakage onto the test strip while enabling controlled transfer between compartments.
2Object-affected harmful factors
If the inner cylinder and outer cylinder are hermetically connected, then leakage is prevented, but the device complexity increases
Solution Approach 1:
The mounting cover integrates multiple functions: it seals the open end of the outer cylinder, houses the liquid supply assembly, and provides structural support for the entire device. By combining these elements into a single integrated component, the number of separate connections and potential leakage points is reduced, simplifying the overall structure while maintaining hermetic sealing.
Solution Approach 2:
The outer cylinder serves multiple functions: it acts as a containment vessel for the treatment liquid, provides structural support for the mounting cover, houses the test strip chamber, and facilitates the flow of virus-adsorbed treatment liquid to the test strip. This multi-functionality reduces the need for additional separate components, simplifying the device while preventing leakage.

Implementation Method 1
the treatment liquid can react with the virus. Then, inverting the outer cylinder, the virus-adsorbed treatment liquid may flow into the test strip chamber
