Rotating Nozzle Assembly for Adjustable Fluid Dispensing Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensers lack versatility in providing multiple dispensing modes, such as spray and stream patterns, which limits their application in various uses and user preferences.
Innovation Solution
A nozzle assembly with a sliding or rotating nozzle mechanism that allows for different dispensing modes by adjusting the alignment of spray channels, enabling the user to switch between 'OFF', 'SPRAY', and 'STREAM' modes through sliding or rotating the nozzle relative to the shroud, thereby modifying the fluid flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single nozzle configuration is used, then the device structure is simple, but the dispensing versatility is limited
Solution Approach 1:
The nozzle is made movable relative to the shroud through sliding or rotating mechanisms, allowing the nozzle to dynamically change its position and orientation. This enables a single nozzle assembly to provide multiple dispensing modes (stream, spray, aerated foam) by adjusting the nozzle's position, thereby improving dispensing versatility without requiring multiple fixed nozzles
Solution Approach 2:
The nozzle assembly is designed to perform multiple functions through a single integrated structure. The movable nozzle can be positioned in different locations and orientations to achieve various dispensing patterns, making the same hardware configuration capable of providing stream mode, spray mode, and aerated foam mode, thus eliminating the need for separate nozzle assemblies for each dispensing mode
2Adaptability or versatility
If multiple nozzle configurations are provided, then the dispensing versatility is improved, but the device complexity increases
Solution Approach 1:
Multiple nozzle positions and orientations are combined into a single movable nozzle assembly. Instead of providing separate fixed nozzles for each dispensing mode, the invention integrates all required configurations into one nozzle that can be moved to different positions, thereby maintaining dispensing versatility while simplifying the overall structure and improving ease of operation through centralized control
3Adaptability or versatility
If the nozzle is made movable to provide different dispensing modes, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The movable nozzle assembly incorporates self-aligning features and mechanical guides that automatically position the nozzle in the correct location and orientation during operation. The sliding and rotating mechanisms include built-in alignment features that ensure precise nozzle positioning without requiring extremely tight manufacturing tolerances on all components, thereby reducing overall manufacturing precision requirements while maintaining dispensing pattern control

AI summary
A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.
