Rotating Ejection Oozing Hose for Plant Irrigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oozing hoses for plant irrigation lack effective dispersion of water, leading to uneven watering and potential clogging, as they rely on linear ejection of water, which results in low dispersal efficiency and vulnerability to clogging from foreign matter.
Innovation Solution
A rotating ejection type oozing hose with a rotation generator at each ejection opening, applying a rotational force to the water stream, dispersing it over a wider area and maintaining uniform pressure, thereby enhancing irrigation coverage and preventing clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of outlets is increased to improve water dispersion coverage, then the irrigation area is expanded, but the water pressure becomes weak toward the direction in which water travels along the hose
Solution Approach 1:
The patent applies a rotational force to the water stream as it exits the hose through the outlets. This dynamic modification transforms the linear water flow into a rotating spray pattern, causing the water to disperse in a circular motion. The rotation mechanism allows the water to cover a wider area without requiring multiple outlets, thereby maintaining adequate water pressure while expanding the effective irrigation zone.
2Shape
If the diameter of outlets is made narrow to improve water dispersion, then the water stream is finer, but the spraying area is reduced and outlets are easily clogged by foreign matters
Solution Approach 1:
Instead of using narrow-diameter outlets that are prone to clogging and limited in spraying area, the patent maintains larger outlet diameters and applies rotational force to the water stream. The rotation transforms the water flow into a dispersed spray pattern that covers a wider area. This approach avoids the clogging issues associated with narrow outlets while achieving fine water distribution through the rotational dispersion mechanism.
3Device complexity
If conventional linear ejection is used to simplify the hose structure, then the device complexity is reduced, but the water dispersion effect is low and uneven wetting occurs
Solution Approach 1:
The patent introduces a rotational force application mechanism at or near the outlets to transform linear water ejection into rotational spray. This dynamic addition, while increasing structural complexity, achieves uniform water dispersion and even wetting across the irrigation area. The rotation mechanism can be integrated into the hose structure in a way that maintains relative simplicity while dramatically improving water distribution uniformity.

Function Achieved in This Case
The rotating ejection type oozing hose effectively disperses water over a large area, ensuring even wetting of plants and soil without cave-in damage, while minimizing the impact of water load and maintaining water pressure, thus providing uniform irrigation without the need for increased outlets or reduced diameters.

AI summary
The present invention relates to a rotating ejection type oozing hose for plant cultivation, comprising: rotation generating means (200) formed in ejection openings (102) that are formed at an interval along the longitudinal direction of a hose (100) so as to endow a flow of water, which is ejected from the inner space (104) of the hose (100) to the outer space (106) thereof, with a rotational force, wherein the rotation generating means (200) comprise barrel-shaped rotating spaces (212), which lead to the ejection openings (102), and which are formed inside the hose (100); each rotating space (212) is defined by a side portion (210) and by a bottom portion (240), the side portion (210) being formed to extend from the inner wall of the hose (100), a rotational force endowing passage (214) being formed on the side portion (210), the rotational force endowing passage (214) being a horizontal passage connected from the inner space (104) of the hose (100) to the rotating space (212), and the bottom portion (240) being configured to close the lower end of the side portion (210); and the rotational force endowing passage (214) is oriented to face a point, which deviates from the center portion (P) of the rotating space (212), thereby endowing the flow of water, which flows into the rotating space (212) via the rotational force endowing passage (214), with a rotational force.
