Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline connections in tap water systems experience nut loosening due to fluid vibrations, leading to potential malfunction and instability.
Innovation Solution
A quick connector structure with a U-shaped fixing portion and flexible portions that securely engage with a defining ring to stabilize the connection valve, using a fixer and defining ring mechanism to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut is used to screw the connecting valve onto the pipeline box, then the connection is initially secure, but the nut gradually loosens due to fluid vibrations
Solution Approach 1:
The patent applies the dynamics principle by designing a fixing mechanism where the U-shaped fixing portion can dynamically adapt to vibrations. The flexible portions allow the structure to move slightly with vibrations rather than resisting rigidly, preventing the loosening that occurs with static nut connections while maintaining secure fixation during normal operation.
Solution Approach 2:
The patent changes the physical parameters of the connection system by replacing a threaded nut connection with a U-shaped clamp structure. This fundamental parameter change from threaded engagement to circumferential clamping eliminates the loosening mechanism inherent in threaded connections subjected to vibrational loads.
2Ease of operation
If a traditional nut connection is used, then the installation process is simple, but the connection requires complex tightening and may still loosen over time
Solution Approach 1:
The patent extracts the problematic threaded nut component from the connection system and replaces it with a U-shaped fixing portion that clamps around the cylinder. This extraction removes the source of loosening while maintaining ease of installation through a simple clamp-and-secure mechanism.
3Reliability
If multiple fixing methods are used to prevent loosening, then connection reliability improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple fixing functions into a single integrated U-shaped fixing portion. This single structure simultaneously provides circumferential clamping, vibration resistance, and secure attachment to the pipeline box, eliminating the need for separate nuts, washers, and locking mechanisms while achieving superior reliability.

AI summary
A quick connector structure of a fluid shock absorber is applicable for a pipeline box configured to connect with a connection valve of at least one pipe line, and the pipeline box includes a coupling orifice configured to connect with the connection valve. The connection valve includes a fixer which has a cylinder, multiple positioning bosses, at least one U-shaped recess, and multiple flexible portions. The coupling orifice has multiple notches, and the coupling orifice also has multiple cutouts corresponding to the multiple flexible portions of the fixer. The coupling orifice accommodates the connection valve, and the multiple notches are engaged with the multiple positioning bosses, thus fixing the connection valve. The pipeline box includes a defining ring, and the defining ring has multiple indents and at least one U-shaped fixing portion. The at least one U-shaped fixing portion is fixed in a same direction as the U-shaped recess.
