Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solutions for raising buried rotary sprinkler heads are labor-intensive, time-consuming, and risk introducing debris into irrigation lines, and are often specific to a particular make and model, lacking universality.
Innovation Solution
A rotary sprinkler riser extension kit comprising an external and internal riser extension that can be easily installed without digging or cutting, raising the sprinkler head's elevation while maintaining functionality and preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional digging and splicing methods are used to raise sprinkler heads, then the sprinkler head elevation is increased, but the installation becomes labor-intensive and time-consuming
Solution Approach 1:
The riser extension system is divided into separate modular components: an external riser extension that attaches to the sprinkler cap and an internal riser extension that fits within the enclosure. This segmentation allows for easy installation without digging or splicing, as each component can be independently attached to achieve the desired elevation increase.
Solution Approach 2:
The external riser extension acts as an intermediary component between the sprinkler cap and the enclosure, providing the elevation increase without requiring modification of the existing irrigation line. This intermediary approach eliminates the need for labor-intensive digging and splicing operations.
2Length of stationary object
If conventional digging and splicing methods are used to raise sprinkler heads, then the sprinkler head elevation is increased, but the complexity of the installation process increases
Solution Approach 1:
By dividing the riser extension into external and internal components that can be independently attached, the system simplifies the installation process. The external component attaches to the cap while the internal component fits within the enclosure, eliminating the need for complex splicing operations.
Solution Approach 2:
The riser extension kit is designed to be self-installing through simple attachment mechanisms. The external riser extension threads onto the sprinkler cap and the internal extension fits within the enclosure, allowing installation without professional digging or splicing expertise.
3Length of stationary object
If conventional splicing methods are used to extend the riser, then the sprinkler head elevation is increased, but debris can enter the sprinkler line causing clogs
Solution Approach 1:
The external riser extension serves as a sealed intermediary component that connects the sprinkler cap to the enclosure without requiring opening the irrigation line. This sealed connection prevents dirt and debris from entering the sprinkler line during installation, maintaining system reliability.
Solution Approach 2:
The invention extracts the riser extension function from the underground irrigation line and places it above ground in the external riser extension component. This extraction eliminates the need to open and splice the underground line, preventing debris contamination.
4Manufacturing precision
If model-specific riser solutions are used, then the fit and functionality are optimized for particular sprinkler models, but the adaptability to different sprinkler makes and models is reduced
Solution Approach 1:
The external riser extension is designed with universal threading specifications that can accommodate multiple makes and models of rotary sprinkler heads. The standardized male and female threading allows the same external extension component to fit different sprinkler models, providing both adaptability and proper fit.
5Length of stationary object
If internal riser extensions are installed within the sprinkler head mechanism, then the elevation is increased, but the installation requires removing and reconstructing the sprinkler cap
Solution Approach 1:
The riser extension is segmented into external and internal components that can be installed independently. The external component attaches to the cap without requiring cap removal, while the internal component fits within the enclosure, eliminating the need to disassemble and reconstruct the sprinkler cap mechanism.
Solution Approach 2:
The external riser extension acts as an intermediary that provides the elevation increase externally, eliminating the need to modify the internal sprinkler cap mechanism. This approach saves installation time by avoiding cap removal and reconstruction.

AI summary
A rotary sprinkler riser extension kit is disclosed for use with a rotary sprinkler. The kit includes an external riser extension having an upper end and lower end, and defining a channel extending through the upper end and lower end. The channel is configured to accommodate the stem of the rotary sprinkler, the upper end is configured to attach to the cap of the rotary sprinkler, and the lower end is configured to attach to the enclosure of the rotary sprinkler. The kit also includes an internal riser extension having a height substantially equal to total length of the external riser extension, a width less than inner width of the enclosure of the rotary sprinkler, means for attaching to the geared lower end of the stem, a lower gear configured to rotate the rotary sprinkler, and means to raise the stem and channel water thereto in response to water pressure at an inlet to the enclosure.
