Rotatable Shutter Aperture for Aerosol Device Odor and Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generation devices with heating mechanisms face issues of cigarette smell and heat retention, leading to inconvenience and potential burns, as well as the spread of internal odors and foreign materials when not in use.
Innovation Solution
An aerosol generation device featuring a first housing with rotatable shutters and a second housing that surrounds the first, allowing for easy opening and closing of the aperture, preventing smell and material leakage, and facilitating air discharge to cool the device when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aperture remains open for easy access, then ease of operation is improved, but cigarette smell and heat retention worsen
Solution Approach 1:
The aperture is divided into multiple shutter blades that can be independently positioned. The shutters are segmented into blade bodies and blade tips, allowing partial opening configurations that balance accessibility with containment of smell and heat.
Solution Approach 2:
The shutter system transitions from a static open/closed state to a dynamic multi-position system. The rotatable second housing enables the shutters to be positioned at various angles, allowing the aperture to adapt its opening degree based on operational needs while maintaining containment when closed.
2Object-generated harmful factors
If the aperture is closed to prevent smell leakage, then harmful factors are reduced, but ease of operation worsens
Solution Approach 1:
The shutters are pre-positioned in a closed state by default, preventing smell and foreign materials from leaking before use. The spring member provides preliminary closing force, ensuring the aperture is sealed ready for operation without requiring user intervention to close it after use.
Solution Approach 2:
The second housing acts as an intermediary mechanism between the user and the shutters. By rotating the second housing, the user indirectly controls the shutter position, making the closing action as easy as opening while providing better seal engagement.
3Object-affected harmful factors
If the aperture remains closed to contain heat, then safety is improved, but heat dissipation worsens
Solution Approach 1:
The shutter system allows partial opening configurations where the aperture is not fully closed. This enables controlled heat dissipation through the partially open shutters, preventing excessive heat accumulation while maintaining sufficient containment to prevent burns during normal operation.
4Reliability
If multiple shutters are used to improve sealing, then reliability is improved, but device complexity worsens
Solution Approach 1:
Multiple shutter blades are merged into a single rotatable assembly controlled by one second housing. Rotating the second housing simultaneously positions all shutters, converting what would be multiple independent controls into a single unified control mechanism, thus reducing operational complexity while maintaining multi-blade sealing effectiveness.

Implementation Method 1
a plurality of shutters (220), provided on the first housing (210), to be rotatable about a virtual line extending in a width direction of the cigarette (7), and to open or close the first aperture (211)
Implementation Method 2
The second housing (230) slidably contacts the plurality of shutters (220) and rotates the plurality of shutters (220) according to a rotating manipulation by a user
