Releasable Mouthpiece Locking Mechanism for Child-Resistant Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mouthpiece locking mechanisms in personal vaporization devices are permanently connected, making it difficult to refill or access the e-liquid reservoir without damaging the device, leading to contamination and failed tests, and lacking child-resistant features.
Innovation Solution
A releasable locking mechanism with doubly hooked arms on the mouthpiece and a release pin allows for secure attachment and detachment, enabling easy access to the e-liquid reservoir while maintaining child-resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanently connected mouthpiece locking mechanism is used, then child-proof safety is improved, but the ability to access e-liquid for refilling or testing is lost
Solution Approach 1:
The locking mechanism is divided into separate components: a mouthpiece with doubly hooked arms and a cartridge with corresponding engagement features. This segmentation allows the mouthpiece to be detached from the cartridge through a controlled release mechanism, enabling e-liquid access while maintaining safety during normal use.
Solution Approach 2:
A release pin or tool acts as an intermediary to trigger the release of the doubly hooked arms from the cartridge. This intermediary mechanism provides a controlled way to access the e-liquid reservoir without compromising the child-proof safety during normal operation.
2Reliability
If a permanently connected mouthpiece locking mechanism is used, then security against unauthorized access is improved, but the ability to perform destructive removal for testing is eliminated
Solution Approach 1:
The locking mechanism transitions from a static permanent connection to a dynamic releasable connection. The doubly hooked arms can be engaged during normal use to provide security, and disengaged when controlled removal is needed for testing or refilling, providing adaptability.
Solution Approach 2:
The mechanical state of the locking mechanism can be changed from locked to unlocked through the release pin. This parameter change allows the system to adapt between different operational modes: secure during use, accessible for testing when needed.
3Ease of operation
If a releasable mouthpiece locking mechanism is used, then access to e-liquid for refilling is enabled, but the complexity of the locking mechanism increases
Solution Approach 1:
The release function is extracted as a separate, simple mechanism (release pin) that acts on the doubly hooked arms. This extraction allows the main locking structure to remain relatively simple while adding the necessary release capability through a separate, easy-to-implement component.
Solution Approach 2:
Instead of requiring complex multi-step release procedures, the mechanism is designed so that a simple insertion of the release pin directly disengages the doubly hooked arms. This inverted approach simplifies the release operation rather than complicating it.
4Adaptability or versatility
If a releasable mouthpiece locking mechanism is used, then the mouthpiece can be removed to save cartridge contents, but the risk of contamination during removal increases
Solution Approach 1:
The release pin serves as an intermediary that enables controlled detachment of the mouthpiece from the cartridge. This controlled release minimizes the risk of contamination by providing a clean, deliberate separation mechanism rather than forceful or uncontrolled removal.
Solution Approach 2:
The release mechanism is designed to be activated before any potential contamination can occur. By providing a pre-planned release path through the doubly hooked arms, the system prevents contamination by avoiding the need for destructive removal methods.

AI summary
A releasable mouthpiece locking mechanism comprises one or more pairs of flexible, hooked arms that can be disposed in an interior portion of a mouthpiece housing. The arms can engage a tube of a vaporization cartridge to lock the vaporization cartridge and can be radially displaced to release the vaporization cartridge.
