Solution Overview

Problem

Existing atomizers for electronic cigarettes lack convenience in refilling tobacco liquid, as they often require complex mechanisms or sealing issues that complicate the injection process.

Innovation Solution

An atomizer design featuring a housing with a rotatable or slidable cover that exposes or covers injecting and vent holes, allowing easy access for refilling tobacco liquid, combined with a sealing mechanism using a seal ring to prevent leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a refillable atomizer is used to reduce usage cost, then the atomizer can be recycled and usage cost is reduced, but the injection process becomes complicated due to sealing issues and complex mechanisms

Engineering Contradiction:
ImproverecyclabilityVSAvoidinjection convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The atomizer is divided into a removable cover portion and a body portion. The cover can be detached to expose the injection hole, separating the refilling operation from the sealed storage state. This segmentation allows the atomizer to maintain sealing during normal use while enabling easy refilling when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover is designed to be movable between a closed position (sealing the injection hole and vent hole) and an open position (exposing the holes for refilling). This dynamic structure allows the atomizer to transition between sealed storage mode and open refilling mode, resolving the contradiction between maintaining seals and enabling convenient injection.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the injection hole is always exposed for easy refilling, then refilling convenience is improved, but liquid leakage occurs due to poor sealing

Engineering Contradiction:
Improverefilling convenienceVSAvoidsealing performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A seal ring is pre-installed around the injection hole and vent hole in the cover structure. This preliminary sealing arrangement ensures that when the cover is closed, the holes are automatically sealed without requiring additional sealing operations, preventing leakage while maintaining refilling convenience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A flexible seal ring (made of elastomeric material) is used to create a reliable seal around the injection and vent holes. The flexible nature of the seal ring allows it to deform and conform to the hole openings, ensuring effective sealing when the cover is closed while allowing easy access when opened.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If a cover mechanism is added to control exposure of injection and vent holes, then sealing performance is improved, but device complexity increases

Engineering Contradiction:
Improvesealing performanceVSAvoidcover mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function and the cover function are merged into a single component. The cover itself incorporates the seal ring, eliminating the need for separate sealing mechanisms. This integration simplifies the overall structure while maintaining effective sealing when the cover is closed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cover serves multiple functions: it seals the injection hole and vent hole when closed, provides a surface for user interaction (rotation or sliding), and protects the internal components. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure.

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