Solution Overview

Problem

Existing aerosol-generating devices face issues with improper positioning or disengagement of aerosol-generating articles during use, which can lead to suboptimal atomization and waste of the article.

Innovation Solution

An aerosol-generating device equipped with a receiving region, an atomizer, a locking element, and a controller. The locking element securely holds the aerosol-generating article in place during operation, and the controller activates the locking element when the atomizer is activated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking element is added to securely hold the aerosol-generating article, then the reliability of the device is improved, but the device complexity increases

Engineering Contradiction:

Improvearticle positioning stabilityVSAvoidlocking mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking element is designed to automatically engage with the aerosol-generating article upon insertion into the receiving region, without requiring manual operation. The controller automatically activates the locking element when the atomizer is activated, making the system self-regulating and reducing operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking element is controlled by a controller that activates it electronically when the atomizer is activated, replacing purely mechanical locking mechanisms with an electronically controlled system that integrates with the device's existing control architecture.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If the locking element is activated continuously, then the article positioning stability is improved, but the energy consumption increases

Engineering Contradiction:

Improvearticle position stabilityVSAvoidlocking element energy consumption

Core Design Contradiction:

Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The locking element is activated periodically based on the operational state of the atomizer. The controller activates the locking element when the atomizer is activated and can deactivate it when the atomizer is not in use, creating a periodic activation pattern that matches the operational requirements.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The locking element is activated in advance when the atomizer is activated, ensuring the article is securely held before atomization begins. This preliminary locking action prevents positional displacement during the entire atomization process.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the aerosol-generating article is allowed to move during operation, then the ease of operation is improved, but the atomization efficiency deteriorates

Engineering Contradiction:

Improvearticle insertion flexibilityVSAvoidatomization efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The aerosol-generating article is designed as a disposable component that is inserted into the receiving region, locked in place during operation, and then discarded after use. This allows for easy replacement of articles while maintaining stable positioning during each individual use cycle.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
