Portable Diffuser Airflow Path for Solid Fragrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diffusers for fragrance diffusion often lack efficient mechanisms to distribute fragrant media into ambient air, relying on ultrasonic transducers and fans which may not effectively disseminate fragrances from solid or semi-solid mediums.
Innovation Solution
A diffuser design featuring a base with openings, a fan, a receptacle with perforated bottom wall, and a lid that forces airflow through a fragrant medium, ensuring fragrance is carried into the ambient air, with optional features like textured surfaces, lighting, and operational mode control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ultrasonic transducers and fans are used to generate atomized droplets and airflow, then fragrance diffusion is achieved, but the mechanism is not effective for solid or semi-solid fragrant mediums
Solution Approach 1:
The invention changes the operational parameters of the fan system by introducing variable speed control with multiple operational modes. The fan can operate at different speeds to optimize airflow for different fragrant medium states (solid, semi-solid, or liquid), allowing the same device to effectively diffuse various types of fragrances by adjusting the airflow parameters rather than changing the entire diffusion mechanism
Solution Approach 2:
The diffuser is designed with a universal receptacle that can accommodate different types of fragrant mediums (solid wax, semi-solid gels, or liquid oils). The perforated bottom wall and adjustable fan speeds create a multi-functional system that reliably diffuses various medium states without requiring separate devices for each fragrance type
2Productivity
If a fan forces airflow through the receptacle and fragrant medium, then fragrance is carried into ambient air, but device complexity increases with multiple components
Solution Approach 1:
The invention merges multiple functions into integrated components. The base houses both the fan motor and power supply circuitry, the receptacle combines the fragrant medium container with a perforated bottom wall for diffusion, and the lid integrates airflow direction control. This consolidation achieves effective fragrance dissemination while reducing the number of separate parts compared to conventional designs
Solution Approach 2:
The device is segmented into modular components (base, receptacle, lid) that can be easily assembled and disassembled. The receptacle with perforated bottom wall is a separate insert that can be removed for refilling, and the lid attaches to complete the airflow path. This segmentation allows for simple manufacturing and maintenance while achieving the required diffusion functionality
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
Effectively disperses fragrance from solid or semi-solid media into the air, providing a more efficient diffusion mechanism compared to traditional methods, with customizable airflow and lighting options for user preference.
Implementation Method 1
The fan is configured to force airflow from an exterior of the diffuser, into the base through the at least one opening of the base, through the plurality of openings formed in the bottom wall of the receptacle, through the receptacle and about any fragrant medium therein, into a volume of space above the receptacle and enclosed by the lid, and out through the at least one opening in the lid to the ambient air external to the diffuser

AI summary
A diffuser includes a base, a fan mounted to the base, a receptacle provided over the fan and mounted to the base, a sleeve mounted on the upper surface of the base and enclosing the fan and receptacle, and a lid mounted over the sleeve. Each of the base and the lid comprises at least one opening formed about a periphery thereof. The receptacle comprises a bottom wall with a plurality of opening formed therethrough and a vertically extending sidewall to retain a fragrant medium therein. The fan forces airflow from an exterior of the diffuser, into the base through the at least one opening, through the plurality of openings formed in the bottom wall of the receptacle, through the receptacle and about any fragrant medium therein, into a volume of space above the receptacle enclosed by the lid, and out through the at least one opening in the lid.
