Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed cavity design is used in the aerosol generating device, then the device structure is simple and easy to manufacture, but the device cannot accommodate cartridges of different sizes and shapes

Engineering Contradiction:
Improvecompatibility with different cartridge typesVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into a fixed outer casing and a removable socket component. The socket can be detached and replaced to accommodate different cartridge types, while the main device body remains unchanged. This segmentation allows versatility without requiring the entire device to be redesigned for each cartridge variation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket is designed as a universal interface that can receive and adapt to multiple cartridge types through its standardized receiving cavity. By making the socket the universal component that interfaces with various cartridges, the device achieves multi-functionality while maintaining a consistent core structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the cavity shape is fixed, then manufacturing is simpler, but modularity and user convenience are reduced

Engineering Contradiction:
ImprovemodularityVSAvoidcavity manufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The cavity functionality is segmented from the main device body and placed in a separate, replaceable socket. This allows the socket to be manufactured with specific cavity shapes tailored to cartridge requirements, while the main device maintains a simple, standardized structure that is easier to manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket acts as an intermediary component between the device body and the cartridge. It provides the customized cavity interface needed for different cartridges without requiring the main device body to be complex or customized for each cartridge type, thus simplifying overall manufacturing.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a standardized receiving cavity is used, then device structure is simplified, but mechanical and electrical connection reliability varies with different cartridge types

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection interface complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connection interface is segmented into the socket component, which can be optimized for reliable mechanical and electrical connections with specific cartridge types. This allows the connection reliability to be improved without complicating the main device body, as the socket serves as a specialized interface layer.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket serves as an intermediary that ensures reliable mechanical engagement and electrical connectivity between the device and various cartridges. It provides the necessary adaptation and connection features without requiring the main device to have complex or variable connection structures for different cartridge types.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention concerns an aerosol generating device (12) comprising: - an outer casing (16); - a receiving cavity (18) ; - a power supply (22); - power connectors (26) arranged in the receiving cavity (18) for connecting a cartridge (14) to the power supply (22), the cartridge comprising a precursor storage portion (31) delimited transversally by a storage portion wall; - a socket (20) delimited transversally by a socket lateral wall. The socket is configured to be in a disengaged configuration in which the socket is away from the receiving cavity and in an engaged configuration in which the socket is inserted at least partially in the receiving cavity. The socket housing is adapted to receive said cartridge so as the storage portion wall faces at least partially the socket inner surface (35). The socket is adapted to guide said cartridge for electrical connection to the power connectors.
