Rotating Nozzle Assembly for Adjustable Squeeze Bottle Spray Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeeze bottle dispensers lack the ability to produce continuous spray patterns similar to trigger sprayers and cannot adjust liquid output patterns, limiting their application and efficiency compared to trigger sprayers.
Innovation Solution
A spray nozzle assembly for squeeze bottles that includes a rotating nozzle with multiple operational states (spray, foam, and stream modes) and a dip tube system, allowing for continuous flow and adjustable output patterns, enabling the bottle to be used in any orientation and providing an 'off' mode for controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a squeeze bottle uses a simple exit orifice for liquid dispensing, then the device complexity is reduced and manufacturing cost decreases, but the liquid output pattern is limited to a single solid stream and cannot be adjusted
Solution Approach 1:
The nozzle assembly incorporates a rotatable nozzle body with multiple operational states (spray, foam, stream modes) that can be dynamically switched by rotating the nozzle to different positions. This dynamic configuration allows the same physical nozzle to produce different liquid output patterns based on its rotational position, resolving the contradiction between simple structure and pattern versatility.
Solution Approach 2:
The nozzle assembly is designed as a multi-functional component that can perform multiple dispensing functions (spray, foam, stream) through a single device structure. The rotatable nozzle with multiple operational states enables one nozzle to replace what would traditionally require multiple separate nozzles or a complex trigger sprayer mechanism, achieving versatility without proportionally increasing complexity.
2Manufacturing precision
If a squeeze bottle is designed to produce only a solid stream pattern, then the manufacturing precision requirements are simplified, but the ability to produce spray patterns similar to trigger sprayers is lost
Solution Approach 1:
The rotatable nozzle mechanism allows the same manufactured nozzle to dynamically switch between spray and stream patterns through rotation to different operational states. This dynamic capability is achieved through mechanical rotation rather than requiring multiple precisely manufactured nozzle types, thereby maintaining simplified manufacturing precision requirements while gaining spray pattern versatility.
3Adaptability or versatility
If a trigger sprayer mechanism is used to achieve adjustable spray patterns, then the liquid output pattern versatility is improved, but the device complexity and material usage increase
Solution Approach 1:
The invention extracts and eliminates the complex trigger mechanism from the sprayer design, retaining only the essential spray pattern generation capability through a rotatable nozzle system. By removing the trigger mechanism while keeping the multi-mode nozzle, the device achieves spray pattern versatility without the associated complexity and material usage of a full trigger sprayer assembly.
Solution Approach 2:
The rotatable nozzle assembly represents a simpler, more cost-effective alternative to a trigger sprayer mechanism. By using a straightforward rotational selection system rather than a mechanical trigger pump system, the invention reduces material usage and manufacturing cost while maintaining the ability to provide multiple spray patterns.
4Productivity
If a squeeze bottle allows continuous spray flow, then the productivity is improved, but the ability to control dispensing (provide an off mode) is reduced
Solution Approach 1:
The rotatable nozzle provides dynamic control over spray flow through positional selection. By rotating the nozzle to different operational states including an 'off' position, the user can control dispensing on demand while maintaining the capability for continuous spray flow when needed, thus resolving the contradiction between productivity and control.
