The electronic aerosol provision device features a housing with an air inlet and an aerosol outlet, where an uninterrupted linear pathway exists between them, and an air inlet with at least one fixed obstruction that reduces the temperature of the aerosol exiting the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the device is made compact to improve ergonomics and ease of storage, then the device size is reduced, but hot aerosol may exit the air inlet and impact users' skin causing discomfort

Engineering Contradiction:

Improvedevice sizeVSAvoidhot aerosol impact on skin

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

A cooling element is introduced as an intermediary component between the aerosol generation chamber and the air inlet. This cooling element acts as a mediator that reduces the temperature of the aerosol before it exits through the air inlet, thereby preventing hot aerosol from impacting the user's skin while maintaining the compact device design.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent introduces a temperature dimension consideration into the compact device design. By adding the cooling element that operates in the thermal dimension, the device addresses the hot aerosol issue without compromising the compactness achieved in the spatial dimensions. This multi-dimensional approach allows simultaneous optimization of size and thermal comfort.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If a cooling element is added to reduce aerosol temperature, then user comfort is improved, but device complexity increases

Engineering Contradiction:

Improveaerosol temperatureVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cooling element changes the temperature parameter of the aerosol as it passes through. By incorporating this thermal parameter modification into the device, the aerosol temperature is reduced from a potentially harmful level to a comfortable level for user contact, while the structural complexity increase is minimized through efficient integration.

Inventive Principle:

Principle #35Parameter changes
