Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sample liquid is left to stand, then microparticles settle and concentration becomes non-uniform, but this causes clogging in feeding tubes and wastes sample liquid
Solution Approach 1:
The container is designed to be rotatable, transforming a static storage system into a dynamic one. By rotating the container, the sample liquid undergoes centrifugal force that prevents microparticle settling and maintains uniform concentration distribution, thereby preventing clogging in feeding tubes while preserving sample liquid for sorting operations.
Solution Approach 2:
The rotational motion of the container creates continuous movement and mixing of the sample liquid, preventing microparticles from settling and aggregating. This mechanical motion maintains uniform concentration distribution and prevents clogging in the feeding tubes, addressing the reliability issue while preserving sample liquid uniformity.
2Stability of the object's composition
If the sample liquid is stirred to disperse microparticles, then concentration uniformity improves, but the container structure becomes more complex
Solution Approach 1:
The container utilizes its own rotational capability to achieve mixing and dispersion of microparticles in the sample liquid. The rotation mechanism itself serves the dual purpose of preventing settling and maintaining uniform concentration, eliminating the need for separate stirring apparatus and reducing overall device complexity while achieving the desired concentration uniformity.
Solution Approach 2:
The rotatable container structure serves multiple functions: it stores the sample liquid, prevents microparticle settling through rotation, maintains uniform concentration distribution, and facilitates easy emptying. This multi-functionality achieves concentration uniformity without requiring additional complex stirring mechanisms, thereby resolving the contradiction between improving composition stability and reducing device complexity.
3Ease of manufacture
If the container has a simple structure, then manufacturing is easier, but the sample liquid cannot be easily taken out
Solution Approach 1:
The container incorporates a rotation mechanism that can be operated manually or automatically. By rotating the container, the sample liquid is brought to the discharge port through gravitational and centrifugal forces, enabling easy liquid removal without requiring complex valves or pumps. This dynamic approach maintains structural simplicity while significantly improving ease of operation for liquid removal.
Solution Approach 2:
The container design allows the sample liquid to flow freely to the discharge port when rotated, creating a gravity-assisted flow path. The rotational motion positions the liquid at the discharge level, enabling simple removal through gravity-driven flow rather than requiring complex pressurization or valve mechanisms, thus maintaining ease of manufacture while improving ease of operation.
