Solution Overview

Problem

Existing atomizers and dispensers often suffer from fluid leakage when tilted, incomplete atomization resulting in larger droplets or streams, and difficulty in evacuating the bottle due to design limitations.

Innovation Solution

A dispensing system featuring a rotatable nozzle with a movable seal mechanism that allows for on/off positioning to control air and fluid flow, combined with a squeezable bottle design including a hand ledge for improved ergonomics and evacuation, which prevents leakage and ensures complete atomization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional aspirator atomizer is used with multiple fluid and air outlets, then atomization can be achieved, but fluid leakage occurs when the device is tilted or falls on its side

Engineering Contradiction:
Improveleak preventionVSAvoidorientation independence
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The seal rib is made movable relative to the outlet opening, allowing it to dynamically adjust its position based on device orientation. When the device is upright, the seal rib maintains sealing contact; when tilted or inverted, gravity causes the seal rib to move away from the outlet, preventing fluid leakage while maintaining adaptability to different orientations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The seal rib utilizes gravity and its own weight to automatically adjust its sealing position without requiring external control mechanisms. The seal rib self-regulates its sealing contact based on the device's orientation, eliminating the need for complex valves or actuators while preventing leakage

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If a traditional atomizer design is used, then fluid can be dispensed, but complete atomization is not achieved resulting in larger droplets or streams

Engineering Contradiction:
Improveatomization qualityVSAvoidatomizer structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The outlet structure incorporates localized features including a specifically configured outlet opening and seal rib geometry that create optimal fluid breakdown conditions. The seal rib's positioning and shape are locally optimized to shear and atomize fluid into fine droplets, achieving complete atomization without requiring complex multi-component atomizer assemblies

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If a bottle with a large bulb or reservoir is used, then liquid can be contained during use and air pocket provided for initial use, but complete evacuation of fluid from the bottle is not possible

Engineering Contradiction:
Improvefluid capacityVSAvoidevacuation efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The dip tube extends to the bottom of the bottle to extract fluid from the lowest point, while the seal rib mechanism at the outlet prevents air ingress during dispensing. This extraction approach allows complete fluid evacuation from the bottle without requiring a large air pocket, maximizing fluid capacity while maintaining full dispensability

Inventive Principle:
Principle #2Taking out (Extraction)
