Garden Sprinkler Driving Structure with Positioning Baffle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garden sprinkler designs face difficulties in adjusting nozzle direction and density, requiring complex misalignment of guiding members and resulting in uneven water spray distribution.
Innovation Solution
A driving structure comprising a main body, sprinkler unit, adjusting base, and driving member with a snap-fit connection and positioning baffle, allowing for easy adjustment of nozzle angles through a single rotation of the driving member, ensuring even and dense water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple guiding members with misaligned openings are used to adjust nozzle direction, then directional adjustment capability is improved, but adjustment complexity and time consumption increase significantly
Solution Approach 1:
The adjustment structure is divided into multiple guiding members (first guiding member with first guiding openings, second guiding member with second guiding openings) that can be independently adjusted. Each guiding member provides a specific degree of freedom for nozzle direction control, allowing complex directional adjustment to be achieved through simpler individual components working together.
Solution Approach 2:
The guiding members are designed to be movable relative to each other, with the second guiding member capable of moving along the first guiding member. This dynamic configuration allows the misalignment between guiding openings to be adjusted on-demand, providing flexible directional control without requiring a completely new structure for each spray pattern.
2Adaptability or versatility
If multiple sliders operate on different parts of the adjusting device, then comprehensive adjustment range is improved, but operational ease deteriorates due to difficult and time-consuming adjustments
Solution Approach 1:
Multiple adjustment functions are merged into a coordinated system where the first and second sliders work together on the same adjusting device. The guiding members are integrated such that their relative movements are coordinated, allowing comprehensive adjustment range to be achieved while simplifying the operational sequence compared to completely separate adjustment mechanisms.
3Adaptability or versatility
If separate adjustments are made at different parts of the spraying device, then comprehensive control capability is improved, but spray uniformity deteriorates due to inability to achieve uniform spray distribution
Solution Approach 1:
The coordinated adjustment mechanism provides inherent feedback through the mechanical linkage between guiding members. As the second guiding member moves relative to the first, the misalignment of guiding openings changes in a controlled manner that naturally distributes spray density more uniformly across the spray pattern, preventing the uneven distribution that occurs with independent separate adjustments.

AI summary
A driving structure for a garden sprinkler comprising: a main body, a sprinkler unit, at least one adjusting base, and at least one driving member. The main body has a main base and an upper cover corresponding to each other, the main base being hollow and having an assembly opening at an end configured to accept the sprinkler unit and for connection to a hose connector; the main base having a recess and a streaming surface, a plurality of first through apertures disposed on the streaming surface corresponding to a plurality of second through apertures with longer lengths disposed on the upper cover; the recess accepting the adjusting base and forming an enclosure with the upper cover; at least one through hole disposed in a middle portion of the main body and defined by integrating the main base with the upper cover, the through hole provided with a positioning baffle.
