Electronic Cigarette Locking Mechanism for Secure Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes with heating devices have difficulty detaching for cleaning due to snap-fit mechanisms and exposed elastic lock buttons, leading to false triggering and inefficient cleaning processes.
Innovation Solution
The electronic cigarette design incorporates a first and second locking member with a driving mechanism, allowing for secure locking and easy detachment of the heating device via an external detaching device inserted through a through hole, preventing false triggering and facilitating cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heating device is secured with a snap-fit mechanism and exposed elastic lock button, then the heating device is firmly locked to the main body, but the exposed lock button is easily extruded when placed in a pocket causing false triggering
Solution Approach 1:
The patent removes the exposed elastic lock button from the external surface and relocates it inside the main body. The button is now accessible only through a through-hole, extracting the problematic exposed component while maintaining its locking function. This resolves the false triggering issue while keeping the detachment mechanism functional.
Solution Approach 2:
The through-hole acts as an intermediary structure that mediates between the need for secure locking and easy detachment. It provides controlled access to the internal lock button, allowing intentional detachment while preventing accidental extrusion. The hole serves as a gateway that reconciles the conflicting requirements.
2Reliability
If the heating device is firmly locked to the main body, then the connection is secure, but the heating device cannot be easily detached for cleaning
Solution Approach 1:
The locking mechanism transitions from a static snap-fit to a dynamic system with a controllable lock button. The button can be pressed to release the lock, allowing the heating device to transition between locked and unlocked states. This dynamic control enables both secure connection and easy detachment when needed.
Solution Approach 2:
The lock button mechanism allows the user to easily engage and disengage the locking mechanism without requiring tools or complex operations. The simple press-action enables self-service locking and unlocking, facilitating quick detachment for cleaning while maintaining secure connection during use.
3Ease of operation
If a through-hole is provided for inserting the detaching device, then the lock button can be accessed for detachment, but the through-hole may allow water entry
Solution Approach 1:
The through-hole is designed with specific local characteristics - it is positioned and sized to provide necessary access to the lock button while minimizing water intrusion risk. The hole's location and dimensions are optimized to balance accessibility with protection against harmful factors like water entry.
