Solution Overview

Problem

Existing aerosol-generating articles lack a mechanism to control the amount of air passing through perforations, making it difficult for users to adjust the cooling level effectively.

Innovation Solution

An aerosol-generating article with a cooling assembly and an air volume regulator that includes a covering member with through holes, allowing users to control the amount of air passing through perforations by moving the air volume regulator, thereby adjusting the cooling level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If perforations are provided for air passage to cool the aerosol-generating article, then cooling effect is improved, but user control over cooling amount is lost

Engineering Contradiction:
Improvecooling effectVSAvoiduser control over cooling
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The air volume regulator is designed to be movable relative to the cooling rod, allowing the user to dynamically adjust the covering area of the perforations. This dynamic adjustment mechanism enables real-time control over the amount of air passing through the perforations, thereby providing user control over the cooling effect while maintaining the cooling function.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If air volume regulator is added to control air passage, then user control over cooling is improved, but device complexity increases

Engineering Contradiction:
Improveuser control over coolingVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The air volume regulator is designed as a separate, movable component that can be independently adjusted relative to the cooling rod. This segmentation allows the control function to be added as a modular element rather than integrating complexity into the entire device structure, thereby improving user control while minimizing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air volume regulator employs a flexible covering structure that can move to cover or expose the perforations. This flexible design achieves the control function with a simple, lightweight component rather than a complex mechanical system, thus improving ease of operation without significantly increasing device complexity.

Inventive Principle:
Principle #30Flexible shells and thin films
