Hose Connector Indent Locking for Anti-Rotation Water Sockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose connectors for watering systems often loosen or disassemble due to rotational movement of sprinklers, leading to unintended sprinkling outside set areas or safety hazards, as they lack effective mechanisms to prevent loosening and rotation.
Innovation Solution
A hose connector design featuring a coupling sleeve with a shoulder having at least one indent, which engages with coupling pins on the water socket to prevent loosening and rotation, allowing for secure and aligned coupling with watering devices like sprinklers, and includes a tapered or chamfered profile to reduce wear and improve service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hose connector with smooth shoulder is used, then the coupling is simple and easy to manufacture, but the connector loosens or disassembles due to rotational movement of sprinklers
Solution Approach 1:
The patent introduces asymmetric features (indentations) on the shoulder surface of the hose connector that engage with corresponding protrusions on the sprinkler body. This asymmetric geometry prevents rotational movement while maintaining a relatively simple overall connector structure, directly resolving the contradiction between coupling stability and structural complexity.
2Reliability
If a hose connector without anti-rotation features is used, then the manufacturing process is simple, but the connector allows unintended rotation and disassembly
Solution Approach 1:
The patent divides the shoulder surface into segmented regions with distinct indentations and engagement features. This segmentation provides anti-rotation functionality through discrete geometric elements rather than complex continuous structures, making the features easier to manufacture while ensuring reliable coupling security.
3Reliability
If a hose connector with basic coupling features is used, then the device complexity is low, but the coupling allows loosening under rotational stress
Solution Approach 1:
The patent incorporates preliminary anti-rotation features (indentations with engagement protrusions) into the connector design before coupling occurs. These pre-configured geometric features automatically engage to prevent rotational loosening, providing durable coupling without requiring complex active mechanisms or post-assembly adjustments.

AI summary
A water socket (110) couplable with a water system, the water socket (110) comprising: a base body (112) defining an annular surface and having a longitudinal axis (LL1); a coupling nipple (114) defined with the base body (112) along the longitudinal axis (LL1), and one or more coupling pins (116) operatively coupled on the annular surface of the base body (112), wherein the one or more coupling pins(116) is movable with respect to the base body (112) along the longitudinal axis (LL1), to an open position and a closed position, and wherein coupling of the hose connector (150) and the water socket (110) is such that the one or more coupling pins (116) at least partially moves to the open position within the base body (112), based on engagement of the coupling pin (116) with the at least one indent (162).
