Solution Overview

Problem

Existing volatile material diffusers often lead to habituation as individuals become accustomed to a single fragrance, limiting the effectiveness of fragrance dispersion and requiring multiple fragrances to be used alternately to prevent this phenomenon.

Innovation Solution

The diffuser employs two containers with wicks and heaters, where one heater is continuously energized to emit a first fragrance and the other is intermittently energized to emit a second fragrance, with optional fan operation and light indicators to control the emission sequence, using a controller to alternate between the fragrances based on predefined or random timing to prevent habituation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single fragrance is continuously emitted from a diffuser, then the fragrance dispersion is simple and device operation is easy, but habituation occurs and fragrance effectiveness decreases

Engineering Contradiction:
Improvediffuser operation simplicityVSAvoidfragrance effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The diffuser alternates between emitting different fragrances at different time intervals. A controller switches between multiple fragrance sources periodically, preventing continuous exposure to a single fragrance and thereby preventing habituation while maintaining operational simplicity

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The diffuser system is divided into multiple independent fragrance emission channels, each with its own fragrance source. The controller selectively activates different channels at different times, enabling fragrance alternation without complicating the overall device operation

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple fragrances are emitted alternately to prevent habituation, then fragrance effectiveness is maintained, but device complexity increases

Engineering Contradiction:
Improvefragrance effectivenessVSAvoiddiffuser structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A single controller performs multiple functions: it manages the switching between different fragrance sources, regulates emission timing, and coordinates the operation of multiple fragrance channels. This multi-functionality allows fragrance alternation without proportionally increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple fragrance sources and their control mechanisms are integrated into a unified diffuser system with a common controller. The controller consolidates the management of multiple fragrances, reducing the overall complexity compared to having separate independent diffusers for each fragrance

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method of emitting two or more volatile materials from a diffuser includes the step of emitting a first volatile material using a first diffusion element for a first randomly determined period of time. The method further includes the step of emitting a second volatile material using a second diffusion element for a section randomly determined period of time.
