Solution Overview

Problem

Existing electronic cigarettes face inefficiencies in liquid consumption due to the wicking effect, leading to unused liquid remaining in the reservoir, as the liquid holding material is exposed to air, causing oxidation of active components like nicotine, and the current designs fail to fully utilize the liquid supply.

Innovation Solution

A novel liquid supply system featuring a spiral container with a center passage and a sealing agent, where the spiral container is designed to facilitate complete liquid consumption through capillary action, ensuring that the liquid is drawn efficiently to the atomizer, and the sealing agent prevents leakage and refilling, allowing for a more efficient vaporization process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If liquid holding material is exposed to air through central passage, then liquid can be supplied to atomizer, but active components in liquid are oxidized

Engineering Contradiction:
Improveliquid supply efficiencyVSAvoidoxidation of nicotine
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces air exposure with an inert or oxygen-free environment by using a sealed spiral container design. The liquid is stored in a spiral configuration that is sealed from air, and liquid is delivered through a controlled interface that prevents oxidation while maintaining supply efficiency to the atomizer.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Ease of operation

If wicking effect is used to draw liquid from reservoir, then liquid can be delivered to atomizer, but liquid cannot be completely consumed

Engineering Contradiction:
Improveliquid delivery mechanismVSAvoidunused liquid remaining
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent segments the liquid delivery system into distinct functional zones: a sealed storage section with spiral configuration and a delivery section with controlled wicking. This segmentation allows complete consumption of liquid in the storage section while maintaining reliable delivery through the interface zone, eliminating the 10-20% waste associated with traditional single-zone designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spiral/dimensional configuration for the liquid container instead of a simple linear or cylindrical reservoir. This spiral arrangement increases the surface area and creates a progressive delivery path that maintains capillary action throughout the entire liquid volume, enabling complete consumption rather than leaving residual liquid at the bottom.

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

3Device complexity

If traditional reservoir design is used, then device structure is simple, but liquid consumption is incomplete

Engineering Contradiction:
Improvereservoir structureVSAvoidusable liquid volume
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The patent employs a nested configuration where the spiral liquid container is positioned within the housing structure, with the atomizer and wicking system nested at the delivery end. This nested arrangement maximizes the usable liquid volume within the available space while maintaining structural simplicity through integrated design rather than adding separate external components.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An electronic cigarette (10) including a liquid supply (34), an air inlet (38), an inhalation port (36), and an atomizer (26). The liquid supply (34) has a housing (340) with a spiral container (341), having an outlet (343) for directing a liquid (330) held within the container (341) out to the atomizer (26) and at least one inlet (342) sealed by a sealing agent (346) to impede movement of the liquid (330). An air channel leads from the air inlet (38) through the atomizer (26) to the inhalation port (36) for directing an aerosol generated at the atomizer (26) to the inhalation port (36).
