Solution Overview

Problem

Aerosol generating apparatuses face issues with aerosol precursor deposition within the consumable cavity, requiring frequent cleaning due to the accumulation of dirt and debris on surfaces and the heating element, necessitating improved access and cleaning mechanisms without increasing the device's external size.

Innovation Solution

An aerosol generating apparatus with a movable closure element that selectively opens and closes an access opening to the consumable cavity, utilizing magnetic or form-fit mechanisms to maintain position, allowing easy cleaning and consumable insertion without altering the device's length, and incorporating magnetic sensors for operational control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a closure element is added to selectively open and close the access opening, then cleaning access and operational control are improved, but device complexity increases

Engineering Contradiction:
Improvecleaning accessVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The closure element is designed to be movable between a first position covering the access opening and a second position exposing it, enabling dynamic control of cavity access for cleaning and consumable insertion without permanent structural modifications

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The closure element serves multiple functions: it provides operational control by preventing accidental activation, facilitates cleaning access, and enables consumable insertion/removal, consolidating multiple needs into a single component

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

2Reliability

AI summary

The present disclosure relates to an aerosol generating apparatus. A drawback with known aerosol generating apparatuses is part of the aerosolised aerosol precursor or the aerosol precursor itself may remain within the aerosol generating apparatus, e.g. within a consumable cavity, and may deposit itself on surfaces or structures within the aerosol generating apparatus, requiring periodic cleaning of said surfaces or structures. Accordingly, there is provided an aerosol generating apparatus (1), comprising a housing (104) having a first side surface and a second side surface opposite the first side surface, a first opening (106a,b) arranged in one of the first and second side surfaces (108a,b), and a cavity (72) arranged for receiving a consumable (70), wherein the first opening is arranged as an access into the cavity (72), through one of the first and second side surfaces, a closure element (100), wherein the closure element (100) is arranged adjacent to the housing (104) and is moveable along the housing (104) between a first position (102a) and a second position (102b), wherein, in the first position (102a), the closure element (100) covers the first opening (106a,b), and in the second position (102b), the closure element (100) exposes the first opening (106a,b).
