Solution Overview

Problem

Existing diffusers are messy, inefficient, and impractical due to water spillage, lack of heat control based on oil type, and large size, making them unsuitable for indoor use.

Innovation Solution

A compact diffuser apparatus with a supporting base, recessed receptacle, and insert containing a heating coil, ventilation holes, and a reservoir that uses a conductive element for power transfer and an identification chip for intelligent heat control, allowing for different heat settings based on liquid type and minimizing spills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a water reservoir is used in existing diffusers, then fragrance dispersion is achieved, but water spillage occurs during refilling and the device becomes messy

Engineering Contradiction:
Improverefilling convenienceVSAvoidwater spillage
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent removes the water reservoir component entirely from the diffuser system. Instead of using water as a carrier medium, the invention uses a wick-based delivery system that directly transports liquid fragrance composition from the reservoir to the heating element, eliminating the need for a separate water reservoir and associated spillage issues.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a wick as an intermediary substance between the liquid fragrance reservoir and the heating element. The wick capillary transports the liquid composition through capillary action, serving as a mediator that eliminates the need for direct water handling and refilling operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the same heat is applied to all oil types, then the device is simple to operate, but dispersion effectiveness varies by oil type

Engineering Contradiction:
Improveheat control by oil typeVSAvoidheat setting mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic heat control where the heating element can adjust its temperature settings based on the specific liquid composition being diffused. The system includes controls that allow users to modify heat levels according to oil type, enabling optimal dispersion for different fragrance compositions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent allows changing the temperature parameter of the heating element to match different liquid composition requirements. By adjusting the heat setting parameter based on the specific oil or fragrance type, the system optimizes vaporization and dispersion effectiveness for each composition.

Inventive Principle:
Principle #35Parameter changes

3Volume of moving object

If existing diffusers are designed for indoor use, then they should be compact, but they become too large when including water reservoirs

Engineering Contradiction:
Improvediffuser sizeVSAvoidindoor suitability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent removes the bulky water reservoir component from the diffuser design. By eliminating the need for a separate water reservoir and using a integrated wick-based delivery system, the overall device volume is reduced, making it more suitable for compact indoor placement on countertops and tables.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the liquid storage reservoir, delivery mechanism, and heating element into a single integrated unit. The wick capillary system is incorporated directly within the housing structure, combining multiple functions into one compact assembly that eliminates the need for separate water reservoir compartments.

Inventive Principle:
Principle #5Merging (Combining)
