Bracket and Housing for Aerosol Device Cartridge Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The aerosol generating device faces issues with the cartridge separating from the body during use, leading to damage and inconsistent power supply, which prevents aerosol delivery to the user.
Innovation Solution
A body for the aerosol generating device is designed with a housing assembly that includes an accommodation space for the cartridge, a battery for power supply, a first printed circuit board, and a bracket to support these components, ensuring stable coupling and miniaturization while preventing rapid temperature increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cartridge is made detachable from the body, then ease of operation is improved, but reliability deteriorates due to separation during use
Solution Approach 1:
The cartridge is designed with a detachable coupling mechanism that allows dynamic transition between attached and detached states. The coupling structure includes engagement features that securely connect the cartridge to the body during use, while allowing intentional detachment by the user, thus maintaining both operational ease and connection reliability.
2Volume of moving object
If the device is miniaturized, then portability is improved, but device complexity increases due to compact component arrangement
Solution Approach 1:
The device employs a nested arrangement where the cartridge is inserted into an accommodation space within the body housing. The battery, printed circuit board, and other components are arranged in a compact, space-efficient manner within the body, with the cartridge containing its own sub-components (reservoir, vibrator, liquid delivery element) in a nested configuration. This nesting approach minimizes overall device volume while managing component complexity through hierarchical organization.
3Device complexity
If the bracket supports multiple components, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The bracket is designed as an integrated support structure that combines multiple functions: supporting the battery, mounting the printed circuit board, and providing structural framework for the accommodation space. By merging these support functions into a single bracket component, the overall device complexity is reduced. The bracket incorporates positioning features and mounting holes with precise tolerances to ensure accurate component placement, addressing the manufacturing precision requirement through careful design of the unified structure.
