Solution Overview

Problem

Existing e-vaping devices face issues with separate formulations reacting with each other in the reservoir, leading to degradation and reduced shelf-life, which affects the sensory experience.

Innovation Solution

The device includes a power supply and control circuitry that independently control dispersion generation by separate cartridges, allowing for independent power supply to each cartridge based on cartridge information, and uses a divider to isolate cartridges, preventing reactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple formulations are held in a single reservoir to provide multiple sensory experiences, then the versatility of the e-vaping device is improved, but the formulations react with each other causing degradation and reducing shelf-life

Engineering Contradiction:
Improvesensory experience varietyVSAvoidformulation stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent divides the single reservoir into multiple separate cartridges, each containing a different formulation. This segmentation prevents direct contact and chemical reactions between formulations while allowing the device to offer multiple sensory experiences by selecting from different cartridges.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a dispersion generator as an intermediary component that processes formulations after they are loaded into separate cartridges. This mediator allows the formulations to be kept separate during storage while still enabling their controlled use for sensory experience generation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If separate formulations are stored together in a reservoir, then the device complexity is reduced, but the formulations degrade due to reactions between them

Engineering Contradiction:
Improvereservoir structureVSAvoidshelf-life
Core Design Contradiction:
Device complexityVSDuration of action of stationary object

Solution Approach 1:

Instead of using a single complex reservoir structure, the patent segments the formulation storage into multiple separate cartridges. This simplifies the overall device architecture while extending shelf-life by preventing chemical reactions between formulations through physical separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs disposable cartridges that are pre-filled with formulations. These cartridges are designed to be replaced rather than maintained, which simplifies the device structure and ensures formulation stability by keeping each formulation in its own sealed cartridge until use.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If multiple formulations are kept in separate cartridges, then the formulation stability is improved, but the device complexity increases due to multiple connectors and control mechanisms

Engineering Contradiction:
Improveformulation stabilityVSAvoidcontrol system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent incorporates cartridge information storage and control circuitry that reads this information to automatically control dispersion generation. This feedback mechanism manages the complexity of multiple cartridges by using automated control based on cartridge identification, reducing the need for complex manual control systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses a universal connector design that can interface with different cartridge types while maintaining a standardized connection protocol. This multi-functional connector handles both electrical connections and mechanical attachment, reducing the overall device complexity despite supporting multiple separate cartridges.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A base for an e-vaping device is configured to couple with multiple cartridges configured to generate separate, respective dispersions. The cartridges may include one or more atomizer assemblies or vaporizer assemblies. The base may include multiple connectors electrically coupled to the power supply. The connectors may be configured to couple multiple dispersion generators to a power supply of the base. The base may include control circuitry configured to independently control dispersion generation by dispersion generators coupled to the base. The control circuitry may independently control dispersion generation by the first and second cartridges based on cartridge information accessed through at least one of the first and second connectors. The control circuitry may control dispersion generation by controlling power supplied to the dispersion generators.
