Solution Overview

Problem

Existing electronic atomization devices face challenges in stabilizing and supporting heating elements, particularly those wound in a cylindrical shape, which are often retained from the outside by annular liquid guide elements, leading to potential instability and inefficiencies in aerosol generation.

Innovation Solution

The atomizer design includes a holder that is partially surrounded by and extends into the cylindrical heating element, providing internal support, along with a flexible liquid guide element squeezed between the tubular element and heating element, and a modular assembly with a lead fastener to secure conductive leads, enhancing stability and airflow path efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the heating element is supported from the outside by an annular liquid guide element, then the heating element can be retained in the device, but the heating element becomes unstable and aerosol generation efficiency decreases

Engineering Contradiction:

Improvestability of heating elementVSAvoidaerosol generation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent inverts the conventional support approach by moving the support structure from external (liquid guide element surrounding the heating element) to internal (holder extending into the heating element from the inside). This inversion resolves the contradiction by providing stable support while maintaining efficient aerosol generation, as the internal holder prevents heating element deformation without interfering with the external liquid guide element's function.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent segments the support function from the liquid guide element by introducing a separate holder component. The holder is configured to extend into the heating element to provide support, while the liquid guide element maintains its external positioning function. This segmentation allows each component to optimize its specific function without compromising the other, thereby improving both stability and aerosol generation efficiency.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the heating element is wound into a cylindrical shape and wrapped by an annular liquid guide element, then the heating element can be retained, but heat transfer to the holder increases

Engineering Contradiction:

Improveretention of heating elementVSAvoidheat transfer to holder

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary structure (the holder with its specific geometry and positioning) that mediates between the heating element and the holder body. The holder is configured to extend into the heating element to provide support while its design (including spacing from the heating element winding) prevents direct heat transfer, thus resolving the contradiction between retention and thermal isolation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the liquid guide element is made flexible and squeezed between the tubular element and heating element, then the liquid guide element can be retained, but the structure becomes more complex

Engineering Contradiction:

Improveretention of liquid guide elementVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a dynamic retention mechanism where the flexible liquid guide element is radially squeezed between the tubular element and the heating element. This dynamic compression provides secure retention while maintaining flexibility in the liquid guide element. The holder's positioning structure (with positioning clamping protrusions) simplifies the overall assembly by providing fixed reference points, thereby reducing structural complexity despite the flexible component.

Inventive Principle:

Principle #15Dynamics
