Solution Overview

Problem

Existing electronic vaporizers face issues with e-liquid overflow and leakage due to the e-liquid injection hole being located on the side of the housing, necessitating additional sealing members that increase size and cost.

Innovation Solution

An electronic vaporizer design with a sealing assembly integrated within the e-liquid storage chamber, using an atomization core sealing member and e-liquid injection hole sealing member to seal the e-liquid injection hole, which opens or blocks the hole without increasing the device's size, utilizing an elastic material and a rotating mechanism for effective sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an additional sealing member is added to seal the e-liquid injection hole, then sealing effectiveness is improved, but device size and manufacturing cost increase

Engineering Contradiction:
Improvesealing effectivenessVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent combines the sealing function with the existing atomization core structure. The atomization core is designed with an integrated sealing assembly that includes a sealing ring, eliminating the need for separate additional sealing members. This merging of functions achieves effective sealing while maintaining compact device size.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The atomization core serves multiple functions: it acts as both the heating element for vaporization and the sealing component for the e-liquid injection hole. The sealing assembly integrated into the atomization core structure provides universal functionality, preventing leakage without requiring dedicated separate sealing components.

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

2Reliability

If an additional sealing member is added to seal the e-liquid injection hole, then sealing effectiveness is improved, but manufacturing cost increases

Engineering Contradiction:
Improvesealing effectivenessVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The sealing function is merged into the atomization core structure, which is already a necessary component of the vaporizer. This integration reduces the total number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining effective sealing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The atomization core performs both vaporization and sealing functions, eliminating the need for separate sealing components. This multi-functionality reduces bill of materials costs and simplifies the manufacturing process, addressing the cost concern while ensuring reliable sealing.

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

3Ease of operation

If the e-liquid injection hole is opened for refilling, then e-liquid replenishment is enabled, but leakage risk increases due to shaking

Engineering Contradiction:
Improverefilling convenienceVSAvoidleakage risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The sealing assembly is pre-configured in the atomization core structure, creating a sealed environment before refilling occurs. When the e-liquid injection hole is opened for refilling, the surrounding sealing structure is already in place, preventing leakage during the refilling process and subsequent shaking.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The integrated sealing assembly provides a protective barrier around the e-liquid injection hole before refilling occurs. This pre-established sealing structure cushions against potential leakage during shaking by maintaining a sealed environment even when the injection hole is temporarily opened.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
