Transparent Hose Nozzle Assembly for Clog-Visible Portable Sprayers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable sprayers have short, small diameter tubing that restricts fluid flow and spray pattern adjustment, leading to clogging issues and difficulty in identifying blockages.
Innovation Solution
A custom sprayer assembly with a larger diameter hose and transparent nozzle, featuring a threaded custom tank fitting, elongated barbed portion, and adjustable spray head, allowing for a longer hose connection and clear fluid flow visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If small diameter tubing is used in conventional sprayers, then the device can be compact and portable, but fluid flow is restricted resulting in small spray patterns
Solution Approach 1:
The patent changes the diameter parameter of the tubing from small (conventional) to large (garden hose, 5/8 inch or greater), fundamentally altering the flow characteristics to enable high volume fluid delivery while maintaining portability through the use of flexible hose material
2Length of moving object
If short tubing is used in conventional sprayers, then the tank can be compact, but the operator must carry the tank close to the surface to be sprayed
Solution Approach 1:
The patent extends the tubing length parameter from short (conventional) to long (20 feet or greater garden hose), enabling the operator to remain at a distance from the spray surface while maintaining fluid delivery capability
3Adaptability or versatility
If conventional spray wands are used, then the structure is simple, but spray pattern adjustment is limited and clogging is difficult to detect
Solution Approach 1:
The patent applies transparency (optical property change) to the nozzle housing, enabling visual detection of fluid flow and clogging conditions without adding mechanical complexity to the nozzle structure
Solution Approach 2:
The patent incorporates an adjustable spray head that can be rotated to different positions (0, 45, 90 degrees) to dynamically change the spray pattern from vertical to horizontal, providing versatility without significant structural complexity

AI summary
A portable sprayer and a sprayer assembly for use with a conventional, pressurizable spray tank are provided. The sprayer assembly includes a custom tank fitting, a length of hose and a custom spray nozzle. The custom tank fitting includes a threaded portion, a nut shaped central portion and an elongated barbed portion extending from the nut shape central portion. One end of the hose is attached to the elongated barbed portion of the custom tank fitting and an opposite end of the hose is attached to the custom spray nozzle. The threaded portion of the custom tank fitting is engageable with corresponding threads in a pressure tank and, preferably, includes ten threads pre inch. The custom spray nozzle includes a sprayer housing that is at least partially transparent.
