Adjustable Garden Sprinkler with Threaded Control Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garden sprinklers have a fixed spraying angle, limiting their coverage area and requiring multiple units or frequent repositioning for larger gardens, making them inconvenient to use.
Innovation Solution
An adjustable garden sprinkler design featuring a base member with connecting pipes and irrigators, where a control member with threaded pipes and apertures allows for adjustable water outlet angle and direction through a screwing cap mechanism, enabling flexible nozzle positioning and enhanced coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sprinkler rod uses a fixed spraying angle structure, then the device complexity is reduced, but the coverage area is limited
Solution Approach 1:
The patent applies the dynamics principle by making the sprinkler rod adjustable in both angle and direction. The control member with threaded pipes allows the sprinkler rod to be dynamically repositioned to different angles and directions, transforming a static fixed-structure into a dynamic adjustable-structure, thereby resolving the contradiction between coverage area and device complexity.
Solution Approach 2:
The patent segments the sprinkler system into distinct functional components: the base member, the control member with threaded pipes, and the adjustable sprinkler rod. This segmentation allows independent adjustment of each component, enabling flexible positioning of the sprinkler rod without requiring complete redesign of the entire system, thus increasing coverage area while controlling overall device complexity.
2Area of stationary object
If multiple sprinklers are used to cover larger gardens, then the coverage area is increased, but the ease of operation deteriorates
Solution Approach 1:
The patent implements universality by designing a single sprinkler unit that can perform multiple functions through adjustment. The sprinkler rod can be positioned at different angles and directions to cover various areas, making one sprinkler equivalent to multiple fixed sprinklers. This eliminates the need to install and manage multiple separate units, thereby improving ease of operation while maintaining large coverage area.
3Area of stationary object
If sprinklers are frequently moved to cover different areas, then the coverage area is increased, but the ease of operation deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the sprinkler rod to be adjusted to different positions and orientations while remaining installed in one location. The threaded pipe mechanism allows quick and easy repositioning without requiring physical relocation of the entire sprinkler unit, thus achieving area expansion through adjustment rather than movement, improving ease of operation.
