An atomizer design featuring a liquid storage shell with isolated cavities, an ultrasonic atomizing core, liquid transporting cotton, a cooling block with atomizing and oil return holes, and an end cap that seals and fixes the cooling block to the core, facilitating heat transfer and diffusion, along with additional components like an insulating sleeve, conductive rod, and fan to enhance cooling and airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the ultrasonic atomizing core operates continuously, then atomization function is maintained, but temperature increases causing liquid decomposition and reduced core lifespan

Engineering Contradiction:

Improveatomization continuityVSAvoidatomizing core temperature

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The device is divided into separate functional cavities: a liquid storage cavity isolated from the functional cavity containing the ultrasonic atomizing core. This segmentation allows independent temperature management of different components while maintaining continuous atomization operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A cooling block is introduced as an intermediary component between the ultrasonic atomizing core and the liquid storage cavity. The cooling block absorbs heat from the atomizing core and transfers it to the liquid, acting as a thermal mediator that prevents temperature buildup while maintaining operation continuity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Temperature

If the cooling block is added to reduce temperature, then heat management improves, but device structure becomes more complex

Engineering Contradiction:

Improveatomizing core temperature controlVSAvoidatomizer structure

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The cooling block serves multiple functions simultaneously: it cools the ultrasonic atomizing core, stores liquid, and acts as a structural support element. By integrating these functions into a single component, the device complexity increase is minimized while achieving effective temperature control.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cooling block merges the cooling function with the liquid storage function into a single integrated component. This consolidation reduces the number of separate parts needed, thereby limiting the increase in device complexity while achieving dual purposes.

Inventive Principle:

Principle #5Merging (Combining)

3Temperature

If the liquid storage cavity and functional cavity are isolated, then heat accumulation is reduced, but manufacturing precision requirements increase

Engineering Contradiction:

Improveheat accumulation controlVSAvoidcavity isolation precision

Core Design Contradiction:

TemperatureVSManufacturing precision

Solution Approach 1:

The liquid storage cavity is extracted and separated from the functional cavity containing the ultrasonic atomizing core. This extraction creates a physical barrier that prevents heat transfer between the two cavities, reducing heat accumulation in the functional cavity while the separation structure itself becomes the focus of precision manufacturing.

Inventive Principle:

Principle #2Taking out (Extraction)
