Solution Overview

Problem

Existing aerosol generation devices lack the ability to control airflow based on user preferences and external stimuli, leading to inconsistent smoking experiences.

Innovation Solution

An aerosol generation device equipped with a sensor unit that detects stimulation to control the opening and closing of multiple airflow passages through independent opening and closing control members, adjusting airflow based on temperature, puff frequency, touch, or duration to enhance user satisfaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the flow of airflow is strengthened to lower suction resistance, then user comfort is improved, but heat sensation increases at the beginning of smoking

Engineering Contradiction:

Improvesuction resistanceVSAvoidheat sensation

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

The device performs preliminary action by detecting temperature or puff count beforehand and pre-adjusting the airflow passage opening in advance. When temperature is high or puff count is low, the system proactively opens the airflow passage to increase airflow, thereby preventing excessive heat sensation before it occurs. This anticipatory adjustment resolves the contradiction by preparing the airflow condition in advance rather than reactively.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the flow of airflow is weakened to increase suction resistance, then smoking satisfaction is improved, but heat sensation increases

Engineering Contradiction:

Improvesuction resistanceVSAvoidheat sensation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device employs feedback by continuously monitoring temperature and puff count, then adjusting the airflow passage opening accordingly. When temperature rises or puff count indicates need for cooling, the system increases airflow opening to reduce heat sensation. This closed-loop feedback mechanism dynamically balances suction resistance and heat sensation, resolving the contradiction adaptively based on real-time conditions.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple airflow passages are added to enable dynamic control, then airflow control flexibility is improved, but device complexity increases

Engineering Contradiction:

Improveairflow control flexibilityVSAvoidnumber of airflow passages

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device applies segmentation by dividing the airflow control into multiple independent airflow passages, each with its own opening/closing control member. This allows selective control of different airflow paths based on detection results (temperature, puff count). By segmenting the airflow system, the device achieves flexible adaptive control while managing complexity through modular independent control units.

Inventive Principle:

Principle #1Segmentation
