Solution Overview

Problem

Existing electronic atomizing devices require separate airflow and suction passages, increasing their volume, complexity, and manufacturing cost due to the need for additional space to prevent liquid leakage.

Innovation Solution

The design integrates the airflow sensing passage into the output passage of the atomizing chamber, utilizing the existing space to reduce complexity and cost by extending the sensing passage through the atomizing chamber and liquid absorbing member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the airflow sensing passage and suction passage are arranged separately to prevent liquid leakage, then liquid leakage is prevented, but the device volume increases and structure becomes more complicated

Engineering Contradiction:

Improveliquid leakage preventionVSAvoidpassage arrangement complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the airflow sensing passage with the output passage by extending the sensing passage through the atomizing chamber and liquid absorbing member, allowing both airflow sensing and liquid protection functions to be integrated within a single passage structure, thereby reducing device complexity while maintaining leakage prevention

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The output passage is designed to serve multiple functions: it acts as both the aerosol output channel and the airflow sensing passage. By making the sensing passage a subset of the output passage structure, the design achieves multi-functionality that reduces overall device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate airflow sensing passage is arranged to prevent liquid pollution, then liquid pollution is prevented, but the manufacturing cost increases

Engineering Contradiction:

Improveliquid pollution preventionVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The sensing passage is combined with the existing output passage structure rather than being a separate component. This integration reduces the number of parts that need to be manufactured and assembled, thereby lowering manufacturing cost while maintaining pollution prevention capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The output passage structure is designed to fulfill dual purposes: aerosol delivery and airflow sensing. This multi-functionality eliminates the need for a dedicated separate sensing passage, reducing component count and manufacturing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If separate airflow sensing passage is arranged to prevent liquid leakage, then liquid leakage is prevented, but the device volume increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The airflow sensing passage is nested within the output passage structure. The sensing passage extends through the atomizing chamber and liquid absorbing member, utilizing the existing spatial arrangement of these components, thereby saving device volume while maintaining leakage prevention

Inventive Principle:

Principle #7Nested doll (Nesting)
