Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid outlet device uses a conventional sealing structure, then the device is simple in structure, but residual liquid continues to discharge after closing affecting user experience
Solution Approach 1:
The patent employs a dynamic sealing mechanism where the sealing element can change its state between open and closed positions. The sealing element is designed to be movable along the liquid flow direction, transitioning from a first position (open) to a second position (closed) to dynamically control liquid discharge and prevent residual liquid leakage.
Solution Approach 2:
The sealing element utilizes elastic deformation as a parameter change mechanism. By applying elastic force to deform the sealing element, the patent achieves reliable sealing contact with the outlet wall, ensuring complete closure and preventing residual liquid discharge while maintaining structural simplicity.
2Reliability
If the liquid outlet device uses an elastic sealing element, then the sealing performance is improved, but the device requires higher manufacturing precision
Solution Approach 1:
The patent employs a flexible sealing element that can elastically deform to conform to the outlet structure. This flexible component compensates for minor variations in manufacturing precision through its elastic properties, ensuring reliable sealing without requiring extremely high manufacturing tolerances for the rigid outlet structure.
3Ease of operation
If the liquid outlet device uses a movable sealing element, then the liquid discharge control is improved, but the device complexity increases
Solution Approach 1:
The sealing element is designed to automatically transition between open and closed states based on liquid pressure and elastic force without requiring external control mechanisms. The element self-regulates its position, moving to the closed state when liquid pressure decreases to prevent residual discharge, thereby maintaining ease of operation while minimizing added complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents residual liquid from being discharged from the liquid outlet opening after the device is closed, enhancing user experience by ensuring efficient and complete liquid management.
Implementation Method 1
The protrusion part is configured to elastically deform when a liquid pressure of the liquid inlet flow channel exceeds a preset value, so that the liquid discharge opening communicates with the liquid outlet flow channel. The protrusion part is capable of resetting against the liquid pressure less than or equal to the preset value.

AI summary
A liquid outlet device and a liquid outlet system are provided. The liquid outlet device includes an outer housing assembly provided with a liquid inlet flow channel and a liquid outlet member installed to the outer housing assembly. The liquid inlet flow channel can form a liquid discharge opening on the outer housing assembly. The liquid outlet member can be enclosed with the outer housing assembly to form a liquid outlet flow channel. A protrusion part of the liquid outlet member can elastically abut against the outer housing assembly, and seal the liquid discharge opening disposed opposite to the protrusion part, so that the liquid can act positively on the protrusion part under the action that the liquid pressure of the liquid inlet flow channel exceeds a preset value. The protrusion part can further reset against the liquid pressure less than or equal to the preset value.
