Solution Overview

Problem

Existing electronic cigarettes typically have a single liquid reservoir, which limits flavor and nicotine customization, and can result in undesirable taste when the liquid solution is depleted faster than it can be replenished.

Innovation Solution

The electronic cigarette system incorporates dual tanks (liquid reservoirs) for storing flavorent and nicotine solutions, each connected to a separate atomizer with a heating element, allowing for independent vaporization and customizable flavor profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single liquid reservoir is used, then the device complexity is reduced, but the flavor and nicotine customization capability is limited

Engineering Contradiction:
Improveflavor and nicotine customization capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single liquid reservoir is segmented into two separate reservoirs: a first reservoir for flavorent solution and a second reservoir for nicotine solution. This segmentation allows independent control and customization of flavor and nicotine delivery, directly resolving the contradiction by enabling flavor and nicotine customization while maintaining manageable device complexity through modular design.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a single atomizer vaporizes both flavorent and nicotine solutions, then the device complexity is reduced, but the liquid solution can be depleted faster than it can be replenished causing undesirable taste

Engineering Contradiction:
Improvecontinuous vaporization reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The single atomizer is segmented into two separate atomizers: a first atomizer dedicated to vaporizing flavorent solution and a second atomizer dedicated to vaporizing nicotine solution. Each atomizer has its own wick and heating element, ensuring independent operation and preventing liquid depletion issues. This segmentation improves reliability of continuous vaporization while keeping device complexity manageable through functional specialization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Separate wicks are introduced as intermediaries between the liquid reservoirs and atomizers. The first wick transports flavorent solution from the first reservoir to the first atomizer, and the second wick transports nicotine solution from the second reservoir to the second atomizer. This intermediary system ensures controlled liquid delivery and prevents depletion issues, improving reliability without excessive complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If dual tanks with separate atomizers are used, then flavor and nicotine customization is enabled, but the device complexity increases

Engineering Contradiction:
Improveflavor and nicotine customization capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into two independent functional units: (1) first reservoir + first wick + first atomizer for flavorent, and (2) second reservoir + second wick + second atomizer for nicotine. This segmentation enables full flavor and nicotine customization capability while managing device complexity through modular, repeatable design patterns that simplify manufacturing and assembly.

Inventive Principle:
Principle #1Segmentation
