Sprinkler Nozzle Adjustment via Pivot-Driven Angular Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzle adjustment apparatuses for sprinklers lack a smooth operation mechanism, as they are not fixed to a pivot, resulting in inefficient adjustment of water distribution patterns.
Innovation Solution
A nozzle adjustment member with a pivot support and adjustment piece having guiding openings, allowing the nozzles to tilt and move at different angles, driven by a pivot system integrated with a hollow pipe and nozzle cover, enabling smooth adjustment of water jets and distribution patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If nozzles are adjusted by parallel displacement or displacement on two-sides in different directions, then sprinkling patterns with different angles can be provided, but the operation is not smooth and the adjustment apparatus is not located by a fixed pivot
Solution Approach 1:
Instead of moving nozzles horizontally through parallel displacement, the invention inverts the adjustment mechanism by rotating nozzles around a fixed pivot point. The adjustment piece rotates around the pivot, causing nozzles to tilt and move at different angles through arc-shaped paths, providing smooth operation and multiple sprinkling patterns.
Solution Approach 2:
The invention introduces an adjustment piece as an intermediary component between the pivot and nozzles. This adjustment piece includes guiding openings that guide nozzles and a control part that enables smooth rotational adjustment around the pivot, mediating the transformation from simple displacement to complex angular movement.
2Adaptability or versatility
If nozzles are moved synchronously at an angle, then different sprinkling patterns can be achieved, but the adjustment apparatus lacks a fixed pivot location
Solution Approach 1:
The invention inverts the approach by establishing a fixed pivot point as the stable reference and allowing nozzles to move relative to it through rotation. This provides both the stability of a fixed pivot location and the versatility of multiple sprinkling patterns through angular adjustment.
Solution Approach 2:
The invention transitions from two-dimensional horizontal displacement to three-dimensional angular movement around a fixed pivot. The nozzles move in arc-shaped paths in multiple dimensions, achieving different sprinkling patterns while maintaining a stable pivot location.
3Adaptability or versatility
If multiple nozzles are adjusted independently, then various water distribution patterns can be created, but the device complexity increases
Solution Approach 1:
The invention merges multiple nozzles with the adjustment piece into an integrated assembly. The adjustment piece includes guiding openings for multiple nozzles and a unified control part, allowing synchronized adjustment of all nozzles through a single rotational motion around the pivot, reducing device complexity while maintaining versatility.
Solution Approach 2:
The adjustment piece serves multiple functions: it guides multiple nozzles, provides the rotational adjustment mechanism, and includes the control part for operation. This multi-functionality reduces the need for separate adjustment mechanisms for each nozzle, simplifying the overall device structure.

AI summary
A nozzle adjustment member for a sprinkler is revealed. A plurality of nozzle tubes aligned in at least one row is positioned on a wall of a hollow pipe. A top end of the nozzle tube is projecting to an outside of the hollow pipe. At least one pivot support is disposed on the outside of the hollow pipe. Each pivot support is pivoted with an adjustment piece having a plurality of guiding openings. The guiding openings are positioned over the plurality of nozzle tubes correspondingly. A nozzle cover is connected with the outside of the hollow pipe for covering the adjustment piece. A plurality of long through holes for mounting the corresponding nozzle tubes is arranged at the nozzle cover. Around a pivot hole, the adjustment piece swings so as to drive the plurality of nozzle tubes moving at an angle and different water distribution patterns are provided.
