Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The development of effective diffusion systems for delivering volatile compounds, such as flavored essential oils, has been hindered by the slow adoption of passive, non-nicotinic, vapor-free, non-electronic devices, contrasting with the rapid growth of the electronic vaping market, especially among adolescents.

Innovation Solution

Development of unpowered, unheated devices for delivering volatile compounds that utilize natural materials and innovative mechanisms for inhalation, such as the FÜM device, which uses a flexible fibrous insert to hold essential oils and is activated by user inhalation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If passive, non-electronic devices are used for delivering volatile compounds, then safety and simplicity are improved, but device adoption and market growth are worsened

Engineering Contradiction:

ImprovesafetyVSAvoiddevice adoption

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The device utilizes the user's own inhalation action to drive the delivery system. When the user inhales, negative pressure is created that automatically draws the volatile compound through the wick and into the mouth, eliminating the need for external power sources or complex mechanisms while maintaining effective delivery

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces electronic heating and powered aerosolization systems with a purely mechanical passive diffusion system. The volatile compound is delivered through natural diffusion and user inhalation rather than electronic atomization, eliminating harmful electrical components while maintaining delivery effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If electronic heating systems are used for vapor generation, then compound delivery efficiency is improved, but device complexity and potential harm are worsened

Engineering Contradiction:

Improvecompound delivery efficiencyVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts and removes the electronic heating system from the device entirely. Instead of heating the volatile compound to generate vapor, the system uses the user's inhalation action to directly draw the compound through the wick and into the mouth, eliminating batteries, heaters, and control electronics

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device employs a disposable wick that is impregnated with the volatile compound. This simple, low-cost consumable replaces complex electronic delivery systems, allowing the device to be discarded after use rather than requiring recharging or maintenance of electronic components

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If heated aerosolization is used for compound delivery, then sensory experience quality is improved, but temperature control and energy consumption are worsened

Engineering Contradiction:

Improvesensory experience qualityVSAvoidtemperature control

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

Instead of heating the compound to create vapor that the user then inhales, the system inverts the process: the user inhales directly to draw the compound through the wick. This reverses the traditional vaporization approach and eliminates the need for temperature control while maintaining effective delivery and sensory experience

Inventive Principle:

Principle #13The other way round (Inversion)
