Flavor Inhalation Pipe Coupling Device for Stable Cartridge Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flavor inhalation pipe systems lack stable coupling of the flavor generation cartridge to the pipe body, leading to unreliable replacement and potential hygiene issues during cartridge change, as the cartridge can drop or slip out, and direct contact is required for handling.
Innovation Solution
A flavor inhalation pipe design featuring a tubular pipe body with a coupling device that elastically secures the mouthpiece to the pipe body, allowing for stable inhalation and easy replacement of the flavor generation cartridge without direct handling, using a cap and engaging lugs within guide grooves to manage the cartridge's insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flavor generation cartridge is detached in its entirety from the pipe body, then the cartridge can be replaced, but the cartridge may drop into or slip out of the pipe body before the user holds it, making reliable replacement not guaranteed
Solution Approach 1:
The mouthpiece serves as an intermediary component that remains coupled to the pipe body while the cartridge is detached. The mouthpiece acts as a stable handle for the user to hold and manipulate during the replacement process, eliminating the need to directly handle the potentially unstable cartridge. The coupling device maintains the mouthpiece's connection to the pipe body through the engagement of the engaging lug with the guide groove, providing a reliable intermediary grip point.
2Ease of operation
If the coupling structure uses engaging projections and grooves, then the cartridge can be detached, but the structure cannot completely eliminate the play of the cartridge with respect to the slider, preventing stable holding
Solution Approach 1:
The coupling system is segmented into two independent functional components: the engagement mechanism (engaging lug with guide groove) that provides stable holding, and the detachment mechanism (push-out direction force) that enables easy removal. This segmentation allows each component to optimize its function without compromising the other, resolving the contradiction between stability and ease of detachment.
Solution Approach 2:
The coupling device transitions from a static engagement state to a dynamic detachment state. During normal use, the engaging lug maintains constant engagement with the guide groove groove wall, providing stable holding. During replacement, the user applies force in the push-out direction to overcome the elastic urging force, dynamically changing the engagement state to allow cartridge removal while maintaining stability during normal operation.
3Ease of operation
If the user directly touches the flavor generation cartridge to hold it, then the cartridge can be manipulated, but hygiene is compromised during replacement
Solution Approach 1:
The mouthpiece serves as a hygienic intermediary that the user can hold without direct contact with their hands touching the mouthpiece interior. The mouthpiece remains coupled to the pipe body through the coupling device, providing a clean handle for manipulation during replacement while eliminating direct hand contact with the mouthpiece, thus maintaining hygiene.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures stable coupling of the mouthpiece to the pipe body, allowing for easy and hygienic replacement of the flavor generation cartridge, preventing accidental drops and maintaining hygiene by avoiding direct contact with the mouthpiece during handling.
Implementation Method 1
a coupling device detachably coupling the proximal end of the pipe body and the distal end portion of the mouthpiece to each other, wherein the coupling device has a coupling position in which the pipe body and the mouthpiece are coupled to each other with the mouthpiece elastically pressed with a predetermined urging force against the pipe body

AI summary
A flavor inhalation pipe includes a hollow cylindrical pipe body (10), a tobacco cartridge (12) accommodated, as a flavor generation cartridge, in the pipe body (10), a mouthpiece (30) coupled to the tobacco cartridge (12) and projecting from the pipe body (10), and a coupling device (40) coupling the pipe body (10) and the mouthpiece (30) to each other. The coupling device (40) has a coupling position in which the mouthpiece (30) is pressed against the pipe body (10) with a predetermined urging force to elastically coupled the two, and a release position which is assumed after the mouthpiece (30) in the coupling position is pushed into the pipe body (10) and then rotated and in which the coupling of the mouthpiece (30) to the pipe body (10) is released.
