Hose Connector Coupling Pins to Prevent Sprinkler Loosening
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 sectors or areas, and lack effective arrangements to prevent such movement.
Innovation Solution
A hose connector design featuring a coupling sleeve with a shoulder and indents that engage with coupling pins on the water socket, preventing loosening and unintended rotation by forming a secure, form-fit connection, and allowing easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional coupling system is used to connect the water socket and sprinkler, then the coupling can be easily assembled and disassembled, but the sprinkler may inadvertently rotate around its axis due to angular momentum, causing the coupling to loosen or disassemble
Solution Approach 1:
The coupling pin is designed with an asymmetric cross-sectional shape (e.g., rectangular or D-shaped) that does not match a circular receptacle, thereby preventing rotational movement of the sprinkler relative to the water socket while maintaining easy linear insertion and removal of the coupling
Solution Approach 2:
The coupling system is divided into separate components (coupling pin and receptacle) that can be independently assembled and disassembled, allowing easy connection and detachment while the asymmetric shape of the pin prevents rotation during operation
2Adaptability or versatility
If the coupling allows free rotation for adaptability, then it can accommodate different orientations, but it leads to unintended sprinkling outside the set sector or area
Solution Approach 1:
The asymmetric cross-sectional shape of the coupling pin restricts the sprinkler to a specific orientation relative to the water socket, ensuring that water is sprayed only in the intended direction and preventing harmful unintended sprinkling outside the set sector

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).
