Solution Overview

Problem

Existing flavor inhalation articles lack the ability to efficiently impart intense sensory experiences to users, as conventional methods for adding sensory components to lining sheets have limitations in intensity and effectiveness.

Innovation Solution

A flavor inhalation article comprising a flavor-generating segment, a mouthpiece segment, and a lining sheet, where the mouthpiece segment and lining sheet contain sensory components, with the lining sheet being liquid-permeable to facilitate migration of the sensory components into the mouthpiece segment, enhancing the sensory experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If sensory components are added only to the lining sheet, then the structure remains simple, but the sensory intensity and effectiveness are insufficient

Engineering Contradiction:
Improvesensory component deliveryVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The invention divides the sensory component delivery system into two segments: the lining sheet and the mouthpiece segment. The lining sheet contains sensory components that contact the lips, while the mouthpiece segment contains additional sensory components that are delivered to the mouth. This segmentation allows each component to contribute differently to the overall sensory experience, increasing total sensory delivery without requiring complete redesign of the entire structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-dimension sensory delivery (lining sheet only) to a multi-dimension approach by adding sensory components to the mouthpiece segment as well. This creates two distinct delivery pathways: one through the lining sheet to the lips and another through the mouthpiece segment to the mouth, effectively adding a spatial dimension to sensory component distribution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the lining sheet is made liquid-permeable to facilitate sensory component migration, then sensory delivery to the mouth is improved, but the structural integrity may be compromised

Engineering Contradiction:
Improvesensory component migrationVSAvoidlining sheet integrity
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The lining sheet is designed with non-uniform properties: the region corresponding to the mouthpiece segment is made liquid-permeable to facilitate sensory component migration, while other regions maintain standard lining sheet properties. This local modification allows the lining sheet to perform its primary function of lip contact while also enabling controlled migration of sensory components to the mouth through the mouthpiece segment region.

Inventive Principle:
Principle #3Local quality
