Magnetic Cover Closure for Aerosol Stick Insertion Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-generating devices lack convenient and automatic mechanisms for opening and closing the insertion space, and fail to prevent foreign substances from entering the device.
Innovation Solution
An aerosol-generating device with a housing featuring an elongated insertion space, a cap with a movable cover, a spring for elastic force application, and a magnetic-force-generating unit that applies attractive or repulsive magnetic forces to control the cover's position, enabling easy opening and closing and automatic closure when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual cover mechanism is used to open/close the insertion space, then the device structure remains simple, but the user convenience and automatic closure function are compromised
Solution Approach 1:
The patent replaces the traditional mechanical spring-latch closure system with a magnetic-force-based system. The magnetic attraction force automatically pulls the cover to the closed position, eliminating the need for complex mechanical latches while maintaining simple overall structure. This resolves the contradiction by providing automatic closure (improving ease of operation) without significantly increasing structural complexity.
Solution Approach 2:
The magnetic force system enables self-service automatic closure - the cover automatically returns to the closed position after stick removal without requiring user intervention. The magnetic attraction continuously acts to close the cover, and the system self-regulates based on whether a stick is present, providing convenient automatic operation while keeping the mechanical structure simple.
2Ease of operation
If the insertion space remains open for stick access, then user convenience is improved, but foreign substances can enter the device
Solution Approach 1:
The magnetic force system prepares the cover in advance by continuously exerting attraction force to keep it closed. Before stick insertion, the cover is already positioned to protect the insertion space. After stick removal, the magnetic force immediately begins closing the cover again, preventing foreign substance entry. This preliminary protective action resolves the contradiction between accessibility and contamination prevention.
Solution Approach 2:
The system dynamically adjusts the cover position based on operational needs. During stick insertion, the cover opens; during normal operation and after removal, the magnetic force dynamically closes and holds the cover. This dynamic behavior allows temporary access when needed while maintaining protection during non-use, resolving the contradiction between ease of access and contamination prevention.
3Reliability
If automatic closure is implemented, then device security is improved, but the mechanism complexity increases
Solution Approach 1:
The patent substitutes complex mechanical automatic closure mechanisms (such as cam-follower systems, pneumatic actuators, or motorized systems) with a simple magnetic force system. The magnetic attraction provides reliable automatic closure through continuous force application, and the system naturally self-regulates based on stick presence. This approach achieves high reliability for automatic closure while keeping the mechanical structure remarkably simple, resolving the contradiction between reliability and complexity.
