Solution Overview

Problem

Conventional aromatherapy diffusers with built-in water tanks are bulky and inconvenient for travel due to their size and are prone to water leaks, which existing solutions have not fully addressed.

Innovation Solution

An aromatherapy diffuser design without a built-in water tank, featuring a diffuser body with an oil storage cavity and an ultrasonic vibrator that can be immersed in a separately provided container, releasing essential oil and creating negatively charged mist when ultrasonic vibrations are applied.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a built-in water tank is included in the diffuser, then the diffuser can store water for extended use, but the overall size of the diffuser becomes larger and less portable

Engineering Contradiction:

Improvewater storage durationVSAvoiddiffuser size

Core Design Contradiction:

Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The water storage function is separated from the diffuser body. Instead of integrating a water tank into the diffuser, the patent uses a separate container for water storage. The diffuser body only contains the ultrasonic vibration mechanism and oil storage cavity, while water is supplied from an external container, achieving functional segmentation that reduces the diffuser's volume while maintaining water storage capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The water tank is extracted from the diffuser system entirely. The patent removes the built-in water tank from the diffuser body and uses a separate container that can be filled independently. This extraction allows the diffuser to be compact and portable while still providing extended water storage through the separate container.

Inventive Principle:

Principle #2Taking out (Extraction)

2Duration of action of moving object

If a built-in water tank is included in the diffuser, then the diffuser can operate continuously for longer periods, but water leaks occur around the tank

Engineering Contradiction:

Improvecontinuous operation timeVSAvoidwater leak

Core Design Contradiction:

Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

By removing the built-in water tank from the diffuser system, the patent eliminates the sealing interfaces that were previously prone to leakage. The separate container for water storage has no complex sealing requirements with the diffuser body, as water is supplied through a simple opening or removable connection, thereby eliminating the water leak problem while maintaining continuous operation capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a separate container as an intermediary between the user and the diffuser system. This intermediary handles water storage and supply functions, isolating the diffuser body from direct water contact except at the ultrasonic vibration interface. This mediation eliminates leakage issues while enabling extended operation through the separate water container.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Volume of moving object

If the diffuser body is made compact for portability, then the diffuser becomes easier to carry, but the oil storage cavity volume is reduced

Engineering Contradiction:

Improvediffuser body volumeVSAvoidessential oil storage capacity

Core Design Contradiction:

Volume of moving objectVSQuantity of substance

Solution Approach 1:

The patent segments the storage functions by using a separate container for water while maintaining a dedicated oil storage cavity within the compact diffuser body. The oil storage cavity is optimized for essential oil storage with a removable cap, allowing sufficient oil capacity in a compact form factor, while water storage is handled externally to avoid increasing the diffuser body volume.

Inventive Principle:

Principle #1Segmentation

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

This design eliminates the risk of water leaks and bulkiness, allowing for a portable aromatherapy solution that can be easily used with any container, providing convenient and efficient diffusion of essential oils while traveling.

Implementation Method 1

an ultrasonic vibrator arranged to generate ultrasonic vibrations, in such a manner that when the diffusion body is partially immersed in the water stored in the container, the essential oil is released to the water from the oil storage cavity while the ultrasonic vibrator is arranged to cause ultrasonic vibrations in the water so as to agitate the water molecules for releasing negatively charged mist and essential oil into ambient air

Methodology Applied

Scientific EffectUltrasonic vibration: Ultrasonic Vibration

AI summary

An aromatherapy diffuser includes a diffuser body and a diffusion device. The diffuser body has an oil storage cavity for storing a predetermined amount of essential oil. The diffusion device is supported in the diffuser body, and includes an ultrasonic vibrator arranged to generate ultrasonic vibrations, in such a manner that when the diffusion body is partially immersed in the water stored in the container, the essential oil is released to the water from the oil storage cavity while the ultrasonic vibrator is arranged to cause ultrasonic vibrations in the water so as to agitate the water molecules for releasing negatively charged mist and essential oil into ambient air.
