Solution Overview

Problem

Existing smoking articles and electronic aerosol provision systems lack consumer control over flavor delivery, as flavorants are present in each inhaled puff at a fixed level and duration, without user-adjustable options.

Innovation Solution

A flavor delivery device comprising an electrical heating element and a flavorant provider with a substrate material that softens and releases flavorant vapor when heated, allowing for controlled flavor addition to the aerosol stream.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If flavorant is included in the source liquid for aerosol generation, then the aerosol delivers consistent flavor with each puff, but the consumer has no control over the level and duration of the flavor experienced

Engineering Contradiction:
Improveconsistent flavor deliveryVSAvoidconsumer control over flavor
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The flavor delivery system is segmented into two independent components: the source liquid reservoir and the flavorant provider. This allows the flavorant to be delivered separately from the aerosol generation process, enabling independent control of flavor levels and duration while maintaining consistent aerosol delivery.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating element's power delivery is made dynamic and adjustable, allowing the consumer to control the temperature and thus the rate of flavorant release. This dynamic control enables adjustment of both flavor intensity and duration according to consumer preference.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If flavorant material is held in a substrate material that softens under heat, then controlled release of flavorant vapor is achieved, but the device complexity increases

Engineering Contradiction:
Improvecontrolled flavor releaseVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The substrate material serving as the flavorant provider is merged with the heating element assembly. The substrate is positioned to receive heat directly from the heating element, combining the flavor release function with the existing thermal management structure and reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The substrate material is selected to undergo a phase change or softening at a specific temperature range. By controlling the heating element's temperature parameter, the system achieves controlled flavorant release without requiring complex mechanical control mechanisms.

Inventive Principle:
Principle #35Parameter changes
