Solution Overview

Problem

Conventional electronic smoking devices face challenges with liquid flow control, as existing wicking systems using cotton or silica materials are difficult to handle, prone to variability, and lack the ability to adjust liquid flow rate with temperature or air suction, leading to thermal degradation and inconsistent performance.

Innovation Solution

The implementation of a capillary tube system comprising two adjustable plates with a variable spacing between them, forming a liquid flow passage from the liquid reservoir to the atomizer, which allows for controlled liquid supply by adjusting the plate separation using electromagnets, thermal expansion elements, or bimetal structures, enabling fine-tuned liquid flow based on user puffing and temperature changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wicking systems using cotton or silica materials are used, then liquid can be supplied to the atomizer, but the system is difficult to handle, prone to variability, and lacks the ability to adjust liquid flow rate

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces conventional mechanical wicking systems (cotton or silica materials) with a capillary tube system formed by two adjustable plates. This substitution enables precise control of liquid flow rate through adjustable plate spacing while eliminating the handling difficulties and variability associated with traditional wicking materials.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a dynamic liquid flow control system where the spacing between the two plates can be adjusted to vary the liquid flow rate. This dynamic adjustment capability allows the system to adapt liquid supply to match user puffing patterns and temperature changes, resolving the contradiction between ease of operation and reliability.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If fixed wicking systems are used, then liquid supply is simple, but the system cannot adjust liquid flow rate with temperature or air suction, leading to thermal degradation

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a dynamic plate spacing mechanism that allows the capillary tube dimensions to be adjusted in response to temperature changes and air suction patterns. This dynamic adaptation enables the system to vary liquid flow rate as needed, preventing thermal degradation while maintaining manageable device complexity through the elegant simplicity of the two-plate design.

Inventive Principle:

Solution Approach 1:

The patent implements a dynamic adjustment mechanism for the plate spacing that enables precise control of liquid flow rate to optimize aerosol production efficiency. The two-plate capillary tube design maintains relatively simple device complexity while providing the necessary control capabilities, as the adjustment mechanism can be integrated into the existing device structure without adding significant complexity.
