Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the e-liquid storage chamber is completely sealed to prevent vaporizable solution leakage, then solution leakage is prevented, but pressure imbalance occurs causing uneven vaporization and dry boiling

Engineering Contradiction:

Improvevaporizable solution leakageVSAvoidvaporization uniformity

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The e-liquid storage chamber is segmented into multiple independent chambers separated by partition walls. Each chamber can independently balance pressure through its own pressure balance hole, preventing pressure imbalance from affecting the entire storage system. This segmentation allows each chamber to maintain proper pressure for uniform vaporization while the overall system remains sealed against leakage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A pressure balance hole with a pressure balance membrane acts as an intermediary between the sealed e-liquid storage chamber and the external environment. The membrane allows pressure equalization to prevent dry boiling while the sealed structure maintains leakage prevention. This intermediary solution resolves the contradiction between sealing and pressure balance.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the e-liquid storage chamber is sealed to prevent leakage, then leakage is prevented, but sensor malfunction occurs due to solution infiltration in the airflow channel

Engineering Contradiction:

Improvevaporizable solution leakageVSAvoidsensor functionality

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The sensor is extracted from the airflow channel and positioned in a location that is not exposed to vaporizable solution. The sensor detects inhalation actions through alternative means that do not require direct exposure to the e-liquid vapor path, eliminating the risk of solution infiltration and sensor malfunction while maintaining the sealed storage chamber.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A protective structure or intermediary barrier is introduced between the sealed e-liquid storage chamber and the sensor area. This intermediary prevents vaporizable solution from reaching the sensor while still allowing the sensor to detect user inhalation actions, thus maintaining both leakage prevention and sensor functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the heating component operates at high temperature to vaporize solution efficiently, then vaporization efficiency is improved, but dry boiling and scorching occur due to pressure imbalance

Engineering Contradiction:

Improvevaporization efficiencyVSAvoidheating component stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Pressure balance holes are provided in the heating component structure to preliminarily establish pressure equilibrium between the heating chamber and external environment. This preliminary pressure balancing prevents negative pressure formation during high-temperature operation, ensuring continuous solution supply to the heating element and preventing dry boiling and scorching while maintaining efficient vaporization.
