Solution Overview

Problem

Aerosol generation devices, such as electronic cigarettes, face difficulties in consumable replacement due to friction and thermal bonding between the consumable and the heating chamber, making the process awkward and inconvenient for users.

Innovation Solution

An aerosol generation device with a cover that moves between open and closed positions, featuring dislodging elements to weaken the attachment between the consumable and the chamber, allowing for easy removal and insertion of consumables without attachment to the cover, utilizing snap-fit connectors and a resilient seal for efficient consumable management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the consumable is tightly fitted to the heating chamber for secure attachment, then the consumable remains stable during heating, but the consumable becomes difficult to remove after use due to friction and thermal bonding

Engineering Contradiction:

Improveconsumable attachment stabilityVSAvoidconsumable removal ease

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The heating chamber is divided into two functional regions: a first region that provides secure attachment during heating, and a second region that facilitates easy removal after use. This segmentation allows the chamber to perform both functions of holding the consumable securely and then releasing it easily, resolving the contradiction between attachment stability and removal ease.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the consumable is heated in the chamber to generate vapor, then the active ingredients are delivered to the user, but the consumable becomes attached to the chamber through thermal bonding and sticky substances

Engineering Contradiction:

Improvevapor generation efficiencyVSAvoidconsumable-chamber adhesion

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful adhesion effect is extracted and isolated to a specific region of the heating chamber. By designing the chamber with a first region for secure attachment and a second region for easy removal, the patent extracts the removal function from the overall heating process, allowing the consumable to be easily separated after vapor generation without compromising the heating efficiency.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the consumable replacement process requires manual manipulation and device reorientation, then the replacement can be performed, but the process becomes awkward and time-consuming for regular use

Engineering Contradiction:

Improvereplacement flexibilityVSAvoidreplacement time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The heating chamber's second region is designed to automatically facilitate consumable removal through its geometric features that reduce friction and thermal bonding. This self-service design allows the consumable to be easily removed without requiring complex manual manipulation or device reorientation, significantly reducing replacement time while maintaining replacement flexibility.

Inventive Principle:

Principle #25Self-service

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

Facilitates easy and convenient replacement of consumables by dislodging them from the chamber without sticking, enhancing user experience and reducing the complexity of the replacement process.

Implementation Method 1

the consumable may undergo thermal expansion when heated, making it more difficult to remove the consumable after use than it was to insert the consumable for use

Methodology Applied

Scientific EffectThermal expansion: Thermal Expansion

Implementation Method 2

heat a consumable without burning it to provide an aerosol (also referred to as a vapour) to a user for inhalation

Methodology Applied

Scientific EffectHeating: Heating

Implementation Method 3

The resilient seal is arranged such that, when the cover is in the closed position, the resilient seal contacts the flange part of the consumable

Methodology Applied

Scientific EffectElasticity: Elasticity

AI summary

An aerosol generation device comprising a chamber, a housing and a cover. The chamber is adapted to receive a consumable. The housing contains the chamber and comprises an opening through which the consumable can be removed from the chamber. The cover is configured to move between an open position where the opening of the housing is exposed and a closed position where the opening of the housing is closed. The aerosol generation device is adapted to generate an inhalable vapor from the consumable. The cover comprises one or more dislodging elements adapted to dislodge the consumable such that, when the cover moves from the closed position to the open position: an attachment is weakened between the chamber and the consumable, and the consumable is partially ejected from the chamber without becoming attached to the cover.
