Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If condensate is allowed to form on the airflow channel during use, then the atomizing function is achieved, but liquid leakage occurs and user experience deteriorates

Engineering Contradiction:

Improveatomizing functionVSAvoidliquid leakage

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful condensate that causes liquid leakage into a beneficial resource by designing liquid suction structures that utilize capillary forces to draw condensate from the airflow channel and transport it back to the atomizing member for re-evaporation and utilization, thereby eliminating waste and preventing leakage

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent introduces liquid suction structures as intermediary components between the airflow channel and the atomizing member. These structures include liquid suction grooves and liquid transport channels that act as mediators to transfer condensate from the harmful location (airflow channel wall) to the useful location (atomizing member)

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If condensate accumulates on the airflow channel wall, then atomization occurs, but liquid drops are brought out during subsequent suction affecting user experience

Engineering Contradiction:

Improveatomization efficiencyVSAvoiduser experience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by designing liquid suction structures that continuously and proactively remove condensate from the airflow channel wall before it can accumulate into liquid drops large enough to be brought out during user suction. The capillary-driven liquid suction grooves actively draw condensate away as it forms, preventing the harmful accumulation that would degrade user experience

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If traditional liquid suction structures are used, then some condensate is absorbed, but insufficient capillary force results in incomplete absorption and liquid leakage

Engineering Contradiction:

Improvecondensate absorptionVSAvoidabsorption completeness

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent applies parameter changes by optimizing the geometric parameters of the liquid suction structures, specifically designing liquid suction grooves with precise width and depth dimensions, and configuring liquid transport channels with appropriate cross-sectional areas. These parameter optimizations ensure that capillary forces are sufficient to completely absorb condensate and transport it reliably to the atomizing member

AI summary

An atomizer and an electronic atomizing device, includes an atomizing member and an airflow channel including an air outlet channel A first liquid suction structure and a second liquid suction structure having a fluid connection with the first liquid suction structure are defined on the air outlet channel to absorb a condensate formed on the air outlet channel by capillary forces. The second liquid suction structure is located between the atomizing member and the first liquid suction structure, and has a capillary force greater than that of the first liquid suction structure. A liquid storage groove that absorbs and stores the condensate by the capillary force is defined on the second liquid suction structure. The condensate in the first liquid suction structure reaches the second liquid suction structure by the capillary force of the liquid storage groove and is then absorbed and stored.
