Cage-like Sprinkler Protector Shielding Head from Debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sprinkler heads in irrigation systems often suffer damage and clogging due to proximity to crops and foreign matter, leading to inefficiencies and blockages, as existing protective measures fail to prevent mud and debris accumulation while also inhibiting water flow.
Innovation Solution
A conical sprinkler protector with circumferentially disposed fingers forming a cage-like structure, featuring a hexagonal base, radially extending webs, and oblate paddles that elevate the sprinkler head, allowing water to flow freely while shielding it from impact and debris, constructed from two identical halves with a molded hinge and connecting clip for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the sprinkler head is positioned close to the ground to minimize evaporation, then water efficiency is improved, but the sprinkler head is damaged by impacting crops and foreign matter
Solution Approach 1:
A protective cage structure is introduced as an intermediary between the sprinkler head and the external environment (crops, foreign matter). The cage allows the sprinkler head to maintain its low position for evaporation prevention while the cage structure absorbs impacts from crops and debris, protecting the sprinkler head from damage.
2Reliability
If a sheath-like collar is attached to the sprinkler head for protection, then the sprinkler head is protected from impact, but mud and debris build-up blocks water flow
Solution Approach 1:
The protective structure is designed with non-uniform geometry - the cage has open spaces and varying wall thicknesses that allow water to pass through freely while still providing protection. The structure has different properties in different locations: solid protection where needed, and open spaces where water flow is required.
Solution Approach 2:
The cage structure functions as a porous protective barrier - it has openings and gaps that allow water to pass through while still providing mechanical protection. The structure is not solid but has controlled porosity that permits water flow while blocking debris.
3Object-affected harmful factors
If a protective cover is used to shield the sprinkler head, then impact damage is reduced, but the cover inhibits water escape from the sprinkler
Solution Approach 1:
The protective structure is divided into multiple segments or bars forming a cage rather than a solid cover. This segmentation allows water to pass through the gaps between segments while still providing protection from impacts. The structure is broken into discrete elements that permit water flow.
4Productivity
If the sprinkler head travels across fields close to crops, then irrigation coverage is improved, but foreign matter is caught inside the sprinkler head causing clogging
Solution Approach 1:
The cage structure serves as an intermediary barrier that prevents foreign matter (debris, plant material) from reaching the sprinkler head interior while allowing water to pass through. The cage filters out large particles before they can enter and clog the sprinkler mechanisms.

AI summary
A sprinkler protector including a housing which engages with a sprinkler or sprinkler pipe and a plurality of circumferentially disposed fingers forming a cage-like shroud over the sprinkler head. The protector shields the sprinkler from impact with foreign material but does not prevent the efficient spraying of water from the sprinkler for the purposes of irrigation.
