Torque-Isolated Connector for Aerosol Device Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustion suction devices face issues where the accommodation portion and power source rotate with the suction port when it is removed, making it difficult to replace or replenish the aerosol source without causing misalignment and potential electrical disconnection.
Innovation Solution
A main body unit with a connector system that includes a first rotation connector to release the connection between the power source and accommodation portion, and a second rotation connector to release the connection between the accommodation portion and suction port, using different torque levels to prevent co-rotation, ensuring secure and easy detachment and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotation connection mechanism is used to attach the atomization unit to the power unit, then the connection between components is secured, but the accommodation portion and power source rotate with the suction port during detachment, causing misalignment and potential electrical disconnection
Solution Approach 1:
The rotation connection mechanism is divided into two independent segments: a first rotation connector for connecting the power source to the accommodation portion, and a second rotation connector for connecting the accommodation portion to the suction port part. This segmentation allows each connector to be optimized independently, enabling the second connector to detach without causing the first connector to rotate, thus preventing misalignment and electrical disconnection while maintaining secure connections.
2Adaptability or versatility
If the suction port is removed from the accommodation portion for replacement, then the aerosol source can be replenished, but the accommodation portion and power source rotate with the suction port, making replacement difficult
Solution Approach 1:
The connection system is segmented into two independent rotation connectors with different torque characteristics. The second rotation connector (accommodation portion to suction port) uses smaller torque, allowing the suction port to be detached without rotating the accommodation portion or power source. This enables easy aerosol source replacement while preventing the problematic co-rotation that made replacement difficult.
3Device complexity
If a single rotation connection is used for all components, then the structure is simple, but all components rotate together during detachment, causing misalignment
Solution Approach 1:
Instead of using a single rotation connection for all components, the system is divided into two separate rotation connectors: the first rotation connector (power source to accommodation portion) and the second rotation connector (accommodation portion to suction port part). This segmentation prevents all components from rotating together during detachment, maintaining alignment precision between the power source and accommodation portion while still allowing the suction port to be removed for aerosol source replacement.

AI summary
A main body unit of an aerosol generation device including a power source; an accommodation portion having a cylindrical shape and configured to store an aerosol source; a suction port part formed with a suction port configured to suck an aerosol made from the aerosol source atomized; and a connector connecting the power source, the accommodation portion, and the suction port part in an axial direction extending a central axis of the maim body unit is provided. The connector includes a first rotation connector configured to release a connection between the power source and the accommodation portion by applying a first torque around the central axis, and a second rotation connector configured to release a connection between the accommodation portion and the suction port part by applying a second torque smaller than the first torque around the central axis.
