Solution Overview

Problem

Electric essential oil diffusers with a housing for receiving a bottle of oil often require users to remove the dropper or tilt the bottle, leading to messy spills and hand contamination, as the bottle needs to be emptied back into the diffuser, which can result in essential oil being spilled on hands or surfaces.

Innovation Solution

An electric essential oil diffuser equipped with a drip cutter having a valve with two positions, actuator, and spring mechanism that automatically opens when the bottle is attached and closes when removed, preventing oil from leaking and maintaining cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bottle is placed upside down to allow oil to flow by gravity into the reservoir, then the oil transfer is simplified, but essential oil spills onto hands or surfaces when emptying the reservoir back into the bottle

Engineering Contradiction:
Improveoil transfer operationVSAvoidessential oil spill
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The dropper is removed before inserting the bottle into the diffuser, and the reservoir is pre-filled or designed to accept oil without requiring manual emptying back into the bottle. This preliminary preparation prevents spillage during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The dropper is extracted and removed from the bottle before use in the diffuser. This eliminates the need to handle the dropper during operation, preventing oil from spilling onto hands when removing or reinserting the dropper.

Inventive Principle:
Principle #2Taking out (Extraction)

2Duration of action of stationary object

If the dropper is removed to allow insertion of absorbent element, then the diffuser can operate continuously, but user's hands become soiled

Engineering Contradiction:
Improvediffuser operation durationVSAvoidhand contamination
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The dropper is completely removed from the bottle before insertion into the diffuser. The bottle is then designed to fit directly into the diffuser without the dropper, allowing continuous operation while preventing hand contamination from handling the dropper during use.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The dropper is removed in advance before the diffuser operation begins. This preliminary action ensures that no further handling of the dropper is needed during operation, preventing hand soiling while maintaining continuous operation capability.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the reservoir is manually filled by the user, then the diffuser can be refilled, but it requires user intervention and potential spillage

Engineering Contradiction:
Improverefilling capabilityVSAvoidspill risk
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The diffuser system is designed to accept the oil bottle directly without requiring manual transfer of oil. The bottle fits into the diffuser housing and oil is delivered automatically via gravity or capillary action, eliminating manual refilling operations and associated spill risks.

Inventive Principle:
Principle #25Self-service

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

The solution prevents hand and surface contamination by ensuring the diffuser remains sealed when not in use, allowing for continuous operation without needing to empty the tank, thus maintaining cleanliness and reducing spills.
