Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional micro pump structure is used, then the pump can transport liquid, but liquid dripping occurs at inlet and outlet ports due to incomplete sealing
Solution Approach 1:
The patent introduces elastic portions with adjustable elastic coefficients to change the mechanical parameters of the sealing system. By adjusting the elastic coefficient, the sealing force can be optimized to prevent liquid dripping while maintaining pump functionality. This directly addresses the sealing performance issue without compromising the pump's liquid transport capability.
Solution Approach 2:
The patent introduces leak-proof portions as intermediary sealing elements between the pump body and the external environment. These leak-proof portions act as mediators that bridge the gap between the mechanical pump structure and the sealing requirement, preventing liquid from escaping at the inlet and outlet ports through the elastic sealing mechanism.
2Reliability
If sealing structures are added to prevent dripping, then sealing performance improves, but device complexity increases
Solution Approach 1:
The patent merges the sealing function with the existing pump structure by integrating elastic portions and leak-proof portions into the inlet and outlet port assemblies. Rather than adding separate complex sealing systems, the sealing elements are combined with the structural components, achieving effective sealing while minimizing additional complexity.
Solution Approach 2:
By adjusting the elastic coefficient parameter of the sealing portions, the patent optimizes the sealing performance without requiring complex mechanical adjustments or multiple sealing layers. This parameter-based approach simplifies the overall device structure while maintaining reliable sealing, avoiding the need for complex adjustable mechanisms.

Function Achieved in This Case
The design prevents liquid from dripping by ensuring the outlet and inlet ports are sealed, allowing for efficient liquid transportation without leakage, offering strong flexibility and applicability through adjustable elastic coefficients.
Implementation Method 1
The first leak-proof member includes a first elastic portion and a first leak-proof portion... the first elastic portion, the first leak-proof portion and the outlet hole are setting in a same straight line... the first leak-proof portion is used for sealing the outlet hole. The second leak-proof member includes a second elastic portion and a second leak-proof portion... the second elastic portion, and the second leak-proof portion are setting in a same straight line... the second leak-proof portion is used for sealing the inlet port.
