Sprinkler Extension Riser for Sunk Pop-Up Heads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pop-up sprinkler heads often sink below the ground surface, reducing their effectiveness in watering due to insufficient height, and existing solutions require significant physical labor or professional intervention for repair.
Innovation Solution
A sprinkler extension device that includes adjustable extension risers and couplings to raise the sprinkler head to the proper height without digging, allowing homeowners to easily and cost-effectively restore adequate water coverage without professional assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the sprinkler unit sinks below the ground surface, then the sprinkler can remain installed in the ground without removal, but the spray cap does not reach sufficient height to adequately spray water
Solution Approach 1:
The sprinkler system is divided into separate components: the fixed underground sprinkler body and the extendable spray cap assembly. This segmentation allows the spray cap to be extended upward independently to achieve sufficient spray height while leaving the sprinkler body installed in the ground.
Solution Approach 2:
The solution adds vertical extension to the spray cap, transitioning from a single-level ground-mounted configuration to a multi-level structure where the spray cap extends above the ground surface to achieve adequate spray height.
2Ease of operation
If a professional repairs the sprinkler by extending the threaded nipple, then the sprinkler height can be restored, but the repair requires significant physical labor and professional intervention
Solution Approach 1:
The invention uses a disposable or easily replaceable extension tube that can be inserted into the sprinkler body without complex tools or procedures. This temporary or replaceable component allows homeowners to quickly restore sprinkler functionality without the time-consuming process of extending the threaded nipple.
Solution Approach 2:
The extension tube design enables homeowners to perform the repair themselves without requiring professional intervention. The simple insertion mechanism allows any homeowner to restore sprinkler height and functionality independently, eliminating the need to hire professionals.
3Length of moving object
If the spray cap sits low in the ground, then the sprinkler remains compact and flush with the surface, but the water spray is blocked by grass and does not reach adequate distance
Solution Approach 1:
The extension tube elevates the spray cap from ground level to a height above the grass, transitioning the spray operation from a ground-level blocked state to an elevated unblocked state, allowing water to spray effectively over the grass rather than being blocked by it.

AI summary
A sprinkler extension device is disclosed to adjust a height of an existing pop-up sprinkler installed in the ground. An example sprinkler extension device includes an extension riser configured to mate on a first end to a sprinkler riser. The extension riser is further configured to mate on a second end to a spray cap of the existing pop-up sprinkler installed in the ground. The example sprinkler extension device also includes an extension coupling configured to mate on a first end to a sprinkler housing. The extension coupling is further configured to mate on a second end to a sprinkler head of the existing pop-up sprinkler installed in the ground.
