Solution Overview

Problem

Existing electronic vaporization devices face challenges in efficiently vaporizing liquid substrates to generate aerosols, particularly in ensuring consistent and controlled delivery of vaporized compounds.

Innovation Solution

The vaporizer incorporates an outer housing with a liquid storage chamber, a first liquid guide element made from an organic porous material, and a second liquid guide element, along with a heating element. The first liquid guide element is designed to seal the liquid storage chamber and guide the liquid substrate, while the second liquid guide element is configured to suck and transfer the liquid substrate to the heating element for vaporization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a liquid storage chamber is sealed with a rigid material, then sealing reliability is improved, but liquid guidance and transfer efficiency deteriorate

Engineering Contradiction:
Improvesealing reliabilityVSAvoidliquid transfer efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by using different materials for different functional regions of the liquid guide element. The first liquid guide element uses an organic porous material that provides both sealing capability and liquid guidance properties in the region where it contacts the liquid storage chamber opening, while maintaining structural integrity elsewhere.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs porous materials for the first liquid guide element, which allows the element to both seal the liquid storage chamber opening and guide liquid through its porous structure. The porosity enables liquid to pass through while the overall structure maintains sealing function.

Inventive Principle:
Principle #31Porous materials

2Stability of the object's composition

If the first liquid guide element is made from a rigid material, then structural stability is improved, but elasticity and adaptation to the opening deteriorate

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptation to opening
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent changes the material parameters by selecting an organic porous material with specific mechanical properties for the first liquid guide element. This material has intermediate stiffness - not too rigid to prevent adaptation, not too soft to lose structural stability. The Shore hardness is controlled within a specific range to balance these properties.

Inventive Principle:
Principle #35Parameter changes

3Strength

If the liquid guide element has high stiffness, then structural integrity is improved, but liquid suction and transfer capability deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoidliquid transfer capability
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The patent applies local quality by creating a gradient or variation in the liquid guide element structure. The element has different stiffness characteristics in different regions - softer near the liquid storage chamber for effective contact and liquid uptake, and more structured elsewhere to maintain overall integrity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses composite material approaches by combining organic porous material with specific structural configurations. This creates a material system that exhibits both structural integrity and high flexibility for liquid transfer, leveraging the properties of the organic porous structure.

Inventive Principle:
Principle #40Composite materials
