Electronic Fragrance Diffuser with Multi-Mode Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic fragrance diffusers lack customization options for diffusion schedules and do not account for olfactory fatigue, limiting user control over fragrance selection and rotation periods.
Innovation Solution
An electronic fragrance diffuser system with a housing for multiple fragrance containers and dispensers, featuring an electronic controller that operates in timed rotation, shuffle, blend, and run-through modes, allowing users to select rotation and shuffle periods, and blend percentages, to manage fragrance diffusion and prevent olfactory fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional electronic fragrance diffusers use fixed diffusion schedules, then device complexity is reduced, but user control and customization capability deteriorate
Solution Approach 1:
The patent implements dynamic diffusion schedules that allow users to customize rotation periods, shuffle intervals, and blend ratios. The electronic controller adapts the diffusion pattern in real-time based on user preferences, transforming a static fixed-schedule system into a dynamic customizable one that resolves the contradiction between simplicity and adaptability
Solution Approach 2:
The diffuser integrates multiple fragrance containers and dispensers that can operate in various modes (timed rotation, shuffle, blend, run-through). This multi-functional design allows a single device to provide both simple fixed scheduling and complex customized scheduling, satisfying both users who want simplicity and those who need customization
2Duration of action of moving object
If conventional diffusers use prolonged exposure to single fragrances, then diffusion duration is extended, but olfactory fatigue increases
Solution Approach 1:
The patent implements periodic rotation through multiple fragrance containers, where each fragrance is diffused for a predetermined rotation period before switching to the next. This periodic action prevents continuous prolonged exposure to a single fragrance, thereby preventing olfactory fatigue while maintaining extended overall diffusion duration through the sequence of multiple fragrances
Solution Approach 2:
The diffusion process is segmented into discrete time intervals (rotation periods) where different fragrances are activated sequentially. By dividing the continuous diffusion into segmented periods with different fragrances, the system prevents any single fragrance from causing fatigue while maintaining continuous diffusion coverage
3Device complexity
If conventional diffusers provide limited diffusion modes, then device complexity is reduced, but user customization capability deteriorates
Solution Approach 1:
The electronic controller is designed to support multiple diffusion modes (timed rotation, shuffle, blend, run-through) within a single unified system. This multi-functional architecture allows the device to offer extensive customization options while maintaining a cohesive control structure, resolving the contradiction between simplicity and versatility

AI summary
A fragrance diffuser includes a housing configured to house at least two fragrance containers each containing a corresponding one of at least two fragrances. The fragrance diffuser also includes at least two dispensers each configured to dispense a corresponding one of the at least two fragrances from a corresponding one of the at least two fragrance containers when the at least two fragrance containers are housed by the housing. The fragrance diffuser further includes an electronic controller configured to operate the fragrance diffuser in at least one of a timed rotation mode, a shuffle mode, a blend mode, or a run-through mode.
