Solution Overview

Problem

Aerosol-generating devices suffer from liquid leakage, exposed mouthpieces, and accidental activation due to accessible buttons or switches, particularly when not in use or stored.

Innovation Solution

A customizable device comprising a first and second inhalation device with removably couplable end portions and a connector hub, allowing for various configurations to prevent liquid leakage and accidental activation, including a power-saving mode when coupled, and enabling interchangeable consumables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mouthpiece is exposed for easy access, then ease of operation is improved, but liquid leakage occurs and harmful factors increase

Engineering Contradiction:

Improveease of access to mouthpieceVSAvoidliquid leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device is divided into separate modular components: a reusable inhalation device and interchangeable consumable cartridges. The mouthpiece is segmented from the consumable, allowing the mouthpiece to remain protected while the consumable can be easily replaced. This segmentation enables the mouthpiece to be inaccessible during storage (preventing leakage) while remaining accessible during use (maintaining ease of operation).

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A connector hub serves as an intermediary component between the inhalation device and consumable cartridges. The connector hub provides a standardized interface that allows multiple consumables to be attached to a single inhalation device, enabling easy access to the mouthpiece while maintaining protection during storage through the modular configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If buttons or switches are accessible for easy activation, then ease of operation is improved, but accidental activation occurs and reliability deteriorates

Engineering Contradiction:

Improveease of activationVSAvoidaccidental activation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The activation mechanism is segmented and integrated into the consumable cartridge rather than being separately accessible on the device body. The button or switch is positioned within the consumable cartridge, requiring the user to attach the consumable to activate the device. This eliminates accidental activation of standalone buttons while maintaining ease of operation through the simple act of attaching the consumable cartridge.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If the device is configured for single consumable to simplify structure, then device complexity is reduced, but adaptability deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidconsumable compatibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The connector hub provides a universal standardized interface that can accommodate multiple types of consumable cartridges. The inhalation device is designed with a single connector hub that accepts various consumable configurations, enabling one device to serve multiple functions with different consumables. This maintains structural simplicity while significantly enhancing adaptability and versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If the device remains inactive during storage to prevent leakage, then reliability is improved, but power management complexity increases

Engineering Contradiction:

Improveleakage preventionVSAvoidpower management configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is pre-configured to automatically transition to an inactive state when the consumable cartridge is attached during storage. The connector hub and control circuitry are pre-programmed to detect the attachment of the consumable and automatically deactivate the heating element and power supply. This preliminary configuration ensures leakage prevention through automatic inactivation without requiring complex user intervention or manual power management.

Inventive Principle:

Principle #10Preliminary action

AI summary

A customizable device may include a first inhalation device and a second inhalation device, each including a mouth end portion and an upstream end portion. In a storage configuration, the mouth end portion of at least one of the first inhalation device or the second inhalation device is removably coupled to the other inhalation device. In an active configuration, the upstream end portion of at least one of the first inhalation device or the second inhalation device is removably coupled to the other inhalation device. A connector hub may couple the inhalation devices.
