Solution Overview

Problem

Existing electronic cigarette vaporizers require complex processes for refilling and often result in resource waste, as they need special tools for liquid replenishment and can experience liquid overflow during refilling.

Innovation Solution

An electronic cigarette vaporizer design where the mouthpiece is dismountable, allowing direct filling of the liquid storage chamber, featuring a closed liquid storage system with a vaporizing tube, absorbent wick, and heating coil, and a vaporization separating sleeve to prevent leakage and facilitate easy reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vaporizer uses a sealed liquid storage chamber with a fixed inlet structure, then liquid leakage is prevented during normal operation, but refilling becomes complex requiring special tools and disconnection of connecting ends

Engineering Contradiction:
Improveliquid leakage preventionVSAvoidrefilling complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The vaporizer is divided into separable components: the mouthpiece assembly can be detached from the liquid storage chamber. This segmentation allows the liquid storage chamber to remain sealed during normal operation while enabling easy access for refilling by simply detaching the mouthpiece assembly, eliminating the need for special tools or disconnecting electrical connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inlet structure is extracted from the sealed liquid storage chamber and integrated into the detachable mouthpiece assembly. This extraction allows the main liquid storage chamber to maintain its sealed structure for leakage prevention, while the inlet function is preserved in the removable part that provides access during refilling.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the vaporizer requires disconnection of connecting ends for refilling, then the sealed structure is maintained, but the refilling process becomes complicated and time-consuming

Engineering Contradiction:
Improvesealed structure maintenanceVSAvoidrefilling time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The vaporizer is segmented into a sealed liquid storage chamber and a detachable mouthpiece assembly. This segmentation allows refilling to be performed by simply detaching the mouthpiece assembly rather than disconnecting electrical connecting ends, significantly reducing refilling time while maintaining the sealed structure of the liquid storage chamber throughout the process.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the vaporizer allows direct filling access, then refilling is simplified, but liquid may overflow into the vaporizing chamber during refilling

Engineering Contradiction:
Improverefilling easeVSAvoidliquid overflow into vaporizing chamber
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The vaporizer structure segments the filling access point away from the vaporizing chamber. The detachable mouthpiece assembly provides the filling access, while the liquid storage chamber maintains its sealed structure during refilling. This spatial segmentation allows easy refilling through the mouthpiece assembly without risking overflow into the vaporizing chamber, as the two chambers remain structurally separated.

Inventive Principle:
Principle #1Segmentation

4Strength

If the vaporizer uses a fixed non-detachable mouthpiece, then structural integrity is maintained, but resource waste occurs when the liquid is used up

Engineering Contradiction:
Improvestructural integrityVSAvoidresource waste
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The vaporizer is segmented into a reusable sealed liquid storage chamber and a detachable mouthpiece assembly. The sealed liquid storage chamber can be refilled and reused, reducing resource waste. The mouthpiece assembly can be detached and replaced as needed. This segmentation maintains structural integrity through proper connection interfaces while enabling resource conservation through refilling capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables recovery and reuse of the liquid storage chamber by allowing it to be refilled through the detachable mouthpiece assembly. Instead of discarding the entire vaporizer when liquid is depleted, users can recover the liquid storage chamber by refilling it, reducing resource waste while maintaining structural integrity through the sealed design.

Inventive Principle:
Principle #34Discarding and recovering
