Inverted Pushbutton Nozzle for Hygienic Perfume Dispensing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing perfume testers require direct skin contact with the pushbutton or bottle, leading to potential germ transmission and excess perfume spray issues.

Innovation Solution

A pushbutton with a vertical nozzle for perfume discharge and excess juice recovery, allowing actuation without gripping the bottle and minimizing skin contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the pushbutton is oriented horizontally with the nozzle facing sideways, then the user can easily press it, but the user must grip the bottle and manipulate the nozzle direction, causing direct skin contact with the tester

Engineering Contradiction:

Improveease of pressing pushbuttonVSAvoidskin contact with tester

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The pushbutton is inverted so that the nozzle opens upward instead of sideways. This allows the user to press the pushbutton from above without needing to grip the bottle or manipulate the nozzle direction, thereby eliminating direct skin contact with the tester while maintaining ease of operation

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

A smelling blotter is introduced as an intermediary between the user's finger and the pushbutton. The user presses the pushbutton through the blotter, which absorbs excess perfume and prevents direct skin contact with the tester components

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the nozzle sprays perfume horizontally, then the spray reaches the user easily, but excess perfume spreads on the bottle and surrounding surfaces

Engineering Contradiction:

Improvespray delivery to userVSAvoidexcess perfume spray

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The spray direction is inverted from horizontal to vertical, spraying upward toward the user's finger or smelling blotter. This prevents excess perfume from spreading on the bottle and surrounding surfaces while still delivering the fragrance to the user

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The excess perfume that would normally be wasted on the bottle and surfaces is converted into a beneficial feature by directing it upward where it can be absorbed by the smelling blotter or user's finger, turning a harmful spillage issue into an effective fragrance delivery mechanism

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Eliminates direct skin contact with the tester, reducing germ transmission and minimizing excess perfume spray on the bottle and surrounding surfaces.

Implementation Method 1

When a pressure is exerted on the pushbutton, perfume can be sprayed onto the skin or onto a smelling blotter

Methodology Applied

Scientific EffectPressure: Pressure Increase

Implementation Method 2

the means for recovering the excess juice make it possible not to wet the finger of the user: all the juice is absorbed by the smelling blotter

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)
