Solution Overview

Problem

There is a demand for an aerosol generating device that is easy to use and carry while producing high-quality aerosols, with the ability to adjust the relative position of cartridges for efficient operation and flavor selection.

Innovation Solution

An aerosol generating device featuring a first cartridge with a delivery hole and a second cartridge with movable chambers, utilizing a magnetic body and electromagnet for adjustable positioning, allowing for easy handling and selection of different materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the second cartridge is fixed to the first cartridge, then the structure is simple and reliable, but the user cannot select different flavors or materials

Engineering Contradiction:
Improveflavor selection capabilityVSAvoidcartridge coupling mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the second cartridge movable relative to the first cartridge through a magnetic coupling mechanism. The electromagnet allows the second cartridge to be positioned at different locations along the first cartridge, enabling the user to select different chambers (and thus different flavors) by moving the second cartridge to align different delivery holes with the first cartridge's opening. This dynamic positioning resolves the contradiction by providing flavor selection capability while maintaining a relatively simple magnetic coupling structure.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the cartridges are designed as separate replaceable components, then the user can easily replace materials, but the device becomes larger and less convenient to carry

Engineering Contradiction:
Improvematerial replacement easeVSAvoiddevice size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent applies the merging principle by integrating the first cartridge (containing the aerosol generation system) and the second cartridge (containing multiple flavor chambers) into a single compact unit. Instead of making them completely separate replaceable components, the magnetic coupling allows them to function as one integrated device that is convenient to carry, while still enabling easy material replacement by simply detaching and reattaching the second cartridge with different flavor configurations.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the second cartridge contains multiple chambers for different materials, then the user can enjoy various flavors, but the relative position control becomes more complex

Engineering Contradiction:
Improveflavor varietyVSAvoidposition control mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the mechanics substitution principle by replacing complex mechanical position control mechanisms with a magnetic field-based control system. The electromagnet can attract or repel the magnetic body in the second cartridge to precisely control its position relative to the first cartridge without requiring complex mechanical linkages, gears, or motors. This allows for simple and reliable position control that enables the user to access different flavor chambers while maintaining device simplicity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
