Solution Overview

Problem

Conventional electronic cigarettes limit users to a single flavor profile, require cumbersome refilling of liquid reservoirs, and are prone to leakage, increasing device size and risk of damage.

Innovation Solution

An electronic smoking article with a micro-bead compartment containing multiple layered flavored micro-beads that release distinct flavors as aerosol flows through, allowing for interchangeable and refillable flavor profiles without liquid leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple liquid storage components are included in a single electronic device, then flavor variety is improved, but device size increases

Engineering Contradiction:
Improveflavor varietyVSAvoiddevice size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The invention divides the flavor storage function into separate micro-beads, each containing a different flavor. These micro-beads are placed in a single storage compartment, allowing multiple flavors to coexist in a compact space. The vapor stream selectively interacts with different micro-beads to deliver various flavors, resolving the contradiction between flavor variety and device size.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple flavored micro-beads are nested within a single micro-bead compartment, which itself is nested within the electronic smoking article housing. This nested arrangement allows multiple flavor units to occupy minimal space while maintaining individual flavor integrity, addressing both flavor variety and compactness requirements.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Duration of action of stationary object

If liquid reservoirs are made refillable for reusability, then device longevity is improved, but leakage risk increases

Engineering Contradiction:
Improvedevice longevityVSAvoidleakage risk
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The invention uses disposable micro-beads instead of refillable liquid reservoirs. The micro-bead compartment can be refilled with new micro-beads, but the micro-beads themselves are not meant to be refilled. This approach maintains device longevity through compartment reuse while eliminating leakage risk by using solid micro-bead structures that cannot leak.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention changes the physical state of flavor storage from liquid (prone to leakage) to solid micro-beads (leak-proof). This parameter change from liquid to solid form maintains the ability to refill the compartment while eliminating the fundamental leakage problem associated with liquid reservoirs.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a single flavor is used in the liquid storage component, then device simplicity is maintained, but flavor versatility deteriorates

Engineering Contradiction:
Improvedevice simplicityVSAvoidflavor versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The micro-bead compartment serves multiple functions: it stores multiple different flavors simultaneously, allows for refilling with various flavor combinations, and provides a unified interface for the vapor stream to interact with all flavors. This multi-functionality achieves flavor versatility without increasing device complexity.

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

Solution Approach 2:

The invention merges multiple flavor units (micro-beads) into a single storage compartment, creating a unified structure that handles multiple flavors. The vapor stream acts as a common medium to extract flavors from different micro-beads, combining multiple flavor delivery functions into one integrated system.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If liquid smoke is transported via wick using capillary action, then device simplicity is maintained, but flavor consistency deteriorates

Engineering Contradiction:
Improvedevice simplicityVSAvoidflavor consistency
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The invention replaces the passive capillary action transport mechanism with an active vapor-driven transport system. The heated vapor stream actively flows through the micro-bead compartment, ensuring consistent and controlled interaction with the micro-beads. This substitution maintains relative simplicity while dramatically improving flavor consistency through controlled vapor-phase mass transfer.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables a seamless transition between flavors without refilling, reduces device size, and minimizes leakage, providing a consistent and changing flavor experience while maintaining a compact and durable design.

Implementation Method 1

a vaporizing chamber with a heating coil attached for the liquid smoke to become vaporized therein

Methodology Applied
Scientific EffectVaporization: Evaporation

Implementation Method 2

the liquid in the cartridge is transported to the vaporizing coil via a transport medium, wherein a common medium is a wick. When the user inhales on the electronic cigarette, the liquid is 'pulled' from the reservoir into the vaporizing chamber using gravity and capillary action in the wick.

AI summary

A system and method for using a plurality of micro-beads that possess multiple flavor layers to provide a user of a smoking article a plurality of flavors that change as the flavor layers are exhausted throughout the smoking experience. When an aerosol flows over the plurality of micro-beads, the outermost flavor layer of each respective micro-bead mixes with the drawn in aerosol and is brought to the user to create a distinct, but flavor layer specific, aerosol. Further provided is the individual micro-bead compartment being attached to a reservoir of liquid that is able to be heated, vaporized, and moved through the compartment.
